Abstract

Child maltreatment is not a new issue. It has existed in various forms in every society

since the early days in history. However, it is only in the past four decades that abuse

and neglect of children has attracted widespread interest among health professionals

and the general public. There is now a large body of evidence that identifies four

main maltreatment forms: physical, sexual, emotional maltreatment and neglect.

Child maltreatment is a substantial public health problem, as it is associated with

immediate and long-term health problems.

Most research into child maltreatment has been conducted in English-speaking,

developed countries. Although there has been a small but steady increase in the

number of studies from less developed countries over the past decade, there remains

a relative dearth of research in these populations, especially in Asia. Over the years,

most research projects around the world tend to be focused on only one type of child

maltreatment (usually either child sexual abuse or child physical maltreatment), and

many studies do not examine risk factors in depth, or address the possible outcomes

of various forms of maltreatment.

Children have always held a very important place in the culture and traditions in

Vietnam. In 1989, Vietnam was the first Asian country and the second country in the

world to sign and ratify the United Nations Convention on the Rights of the Child.

Since then Vietnam has adopted various measures to promote children’s rights and

particularly children’s rights to be protected from abuse and exploitation. Despite

strong political support for the rights of children, there is little formal research into

child maltreatment. From the small amount of available evidence and media reports,

it appears that children in Vietnam are vulnerable to maltreatment, just as they are all

over the world. It is clear that information about the extent and health consequences

of different forms of child maltreatment from scientifically sound studies is still far

from sufficient. Thus, more research is essential to ensure effective and culturally

appropriate responses to protect children from maltreatment.

v

The primary aim of this research was to examine the nature and co-occurrence of

four forms of child maltreatment including sexual, physical, emotional maltreatment

and neglect among Vietnamese secondary and high school adolescents in both urban

and rural settings, and determine the extent to which such adverse experiences

impact on self-reported health risk behaviours and physical and mental health.

A mixed methods design including qualitative interviews and focus group

discussions, and a cross-sectional survey was employed in this study. Incorporation

of qualitative inquiry added a cultural dimension on child maltreatment and informed

to develop appropriate quantitative measures.

Following 8 focus group discussions and 16 in-depth interviews as well as a pilot

study of 299 adolescents in Vietnamese schools, a cross-sectional survey of 2,591

adolescents randomly selected from eight secondary and high schools in one urban

district and one rural district was undertaken between 2004 and 2005. Data were

collected by self-administered questionnaires in class rooms. Key information

included demographics, family characteristics and environment, and four scales

measuring sexual abuse, emotional and physical maltreatment and neglect as well as

standard brief assessments of health related risk behaviours, mental and general

physical health.

The study clearly revealed that experiences of different forms and co-occurrence of

child maltreatment among school adolescents were prevalent in Vietnam. The

prevalence estimates of at least one type of physical and emotional maltreatment,

neglect and sexual abuse were 47.5%, 39.5%, 29.3% and 19.7% respectively. A

significant proportion of respondents (41.6%) was exposed to more than one form of

child maltreatment, of which 14.5% and 6.3% experienced three or four

maltreatment forms.

Results from multivariate logistic regression analyses showed that the prevalence of

child physical and emotional maltreatment and neglect among adolescents was not

statistically different between urban and rural districts. However, children from rural

vi

schools were more likely to report unwanted sexual experiences than their

counterparts in urban schools. There was no significant gender difference in reports

of adverse sexual experiences. In contrast, girls were more likely to report emotional

maltreatment and neglect whereas boys were more likely to experience physical

maltreatment. Furthermore, family environment assessed by parental quarrelling,

fighting, perceived quality of parental relationship and emotional support appeared to

be the most consistent factors significantly predicting each form of child

maltreatment.

After controlling for a wide range of potential confounding factors, many significant

correlates between each type of maltreatment, each level of maltreatment co-

occurrence and each health risk behaviour were found. In general, the pattern of

correlations between child maltreatment and health risk behaviours was similar for

females and males. Emotional maltreatment significantly correlated with most

behaviours examined. Physical maltreatment seems more likely to be associated with

involvement in physical fights and being threatened. Sexual abuse was significantly

related to smoking, drinking, being drunk, and involvement in fighting. Statistically

significant associations between neglect and self-harm such as involvement in

fighting, feeling sad and hopeless, suicidal thoughts and attempts were found.

Clearly, co-occurrence of child maltreatment was significantly associated with

almost all examined health risk behaviours and a dose-response relationship was

observed in most of the dependent variables.

Regarding continuous measures of mental and physical health, multivariate

regression analyses revealed that presence of four types of child maltreatment

explained a small but significant proportion of variance (from 5% to 9%), controlling

for a wide range of background variables. Additionally, while each form of child

maltreatment had independent effects on depression, anxiety problems, low self-

esteem and poor physical health emotional maltreatment appeared to be the strongest

influence on mental and physical health of both female and male adolescents.

Analysis of variance also clearly suggested that exposure to increasing numbers of

vii

maltreatment forms significantly increased the risk of mental and physical health

problems in a dose-response fashion.

The present study extends a small body of previous research examining poly-

victimization in developed nations to an Asian country. The data contribute new

knowledge on cross-cultural child maltreatment problems. Considerable

commonalities as well as some differences in the findings in Vietnam compared with

earlier research were found. One important conclusion concerns the significant

independent associations between various types of child maltreatment, as well as the

cumulative effects of poly-victimization on a wide range of health risk behaviours,

depression, anxiety, self-esteem, and general physical health. This pioneering

research in Vietnam provides timely and substantial evidence that can be used to

raise public awareness of the nature of child maltreatment and the harmful effects of

not only sexual and physical abuse but also other forms of emotional maltreatment

and neglect which have not received attention before. These results from a

community-based sample have demonstrated the urgent need for prevention

programs. The current study provides an impetus for more comprehensive research

in this sensitive area in the near future so that culturally and politically relevant

evidence-based responses to child maltreatment can be developed in Vietnam.

Chapter 1: Introduction 1.1 Background

For a long time in many parts of the world, child maltreatment has been documented

in art and literature. However, the issue did not attract widespread attention from

health professionals and the general public until the early 1960s, with the publication

of an influential article “The battered child syndrome” in the Journal of the American

Medical Association, by paediatrician Henry Kempe and his colleagues (1962). As a

direct impact of this article, before the year 1970, all states in the US had established

child abuse reporting laws (Cicchetti & Carlson, 1989). By the end of the 1960s,

child abuse had emerged as a social problem in other parts of the world, and reports

of child abuse cases flooded the periodical literature (Freeman, 2000).

According to the World Health Organization (WHO), child maltreatment including

child physical maltreatment, emotional maltreatment, sexual abuse, and neglect, is a

public health problem in both developed and developing countries, impairing the

health and welfare of children and adolescents. WHO has estimated that 40 million

children aged 0-14 years around the world suffer from abuse and require health care

and social services (McMenemy, 1999). Consequences of child abuse are often

immediate, impinging on the formative years and can be long lasting, following

victims throughout their lives. Moreover, child abuse affects not only children, but

also other family members and can ruin or contaminate communities, damaging

complex social and familial relations and interactions. Over the past decades, many

researchers have documented the higher frequency of health problems among

maltreated survivors. Possible pathways through which maltreatment might influence

health are behavioural, social, cognitive, and emotional. These four types of

influences form a complex matrix of inter-relationships, impacting on health

(Kendall-Tackett, 2002).

1

This global problem requires both international and local collaborations to design

and implement culturally acceptable ways to alleviate the burden on children,

families, and communities. McMenemy (1999) summarised the international

recommendations to combat the child maltreatment problem as follows:

• Development of worldwide data collection on child maltreatment;

• Sharing of interventions and best practices for prevention;

• Continuing evaluation and research on prevention; and

• Development of national programmes for prevention and provision of social

support for children and families.

While progress in terms of extensive research, development and implementation of

preventive measures and signs of declining abuse rates may have been made in North

America, Australia and Western Europe (Dunne, Purdie, Cook, Boyle, & Najman,

2003; Jones, Finkelhor, & Kopiec, 2001), there remains a significant need to advance

initiatives in the countries of Asia, South America, Eastern Europe, and Africa. The

extent of child maltreatment and its impact in most parts of the developing world is

unknown or not well documented, but there is increasing evidence that problems do

exist and are of growing concern to policy makers, health professionals, researchers

and the general public (D'Antonio, Darwish, & McLean, 1993; Kawewe & Dibie,

1999; Qiao & Chan, 2005).

Over the past decade there has been a small but steady increase in the number of

articles from less developed countries published in English language journals such as

“Child Abuse & Neglect” and “Child Maltreatment” (Lachman et al., 2002).

However, there remains a relative dearth of research on child abuse in developing

countries in general and within Asian cultures in particular. Additionally, a review of

the literature on child maltreatment in less developed world reveals that most

research projects tend to be targeted at the prevalence of only one type of child

maltreatment (usually either child sexual abuse or child physical maltreatment), and

many studies do not examine risk factors in depth, or address the possible outcomes

of maltreatment.

2

When people report that they were maltreated as a child it should be understood that

this often occurs within a complex web of childhood adversity. Often, children are

maltreated in multiple ways (Higgins & McCabe, 2000a; Moeller, Bachmann, &

Moeller, 1993). The co-occurrence of various maltreatment forms may have either a

cumulative or an interactive impact. Wolfe and McGee (1994) argued that different

types of child maltreatment interact in a manner that is more detrimental to

development than the influence of one type alone. However, the majority of child

maltreatment studies have examined the impact of individual types of child

maltreatment in isolation (Higgins & McCabe, 2000b). Evidence from recent

research examining more than one type of child maltreatment has drawn attention to

the fact that co-occurrence of child maltreatment is reported by many respondents

(Benbenishty, Zeira, & Astor, 2002; Meston, Heiman, Trapnell, & Carlin, 1999;

Scher, Forde, McQuaid, & Stein, 2004; Stephenson et al., 2006). Clearly, attempts to

evaluate co-occurrence and a full exploration of the interrelationships of multiple

forms of child maltreatment in a single study are critical to understanding relative

and cumulative effects of child maltreatment.

Although the Vietnamese government has demonstrated commitment to promotion

of children’s rights and child protection most activities implemented across the

country have targeted extreme cases of sexual abuse such as child rape or

commercial sexual exploitation of children (UNICEF, 2002). There is a paucity of

research examining the extent to which Vietnamese children are exposed to child

maltreatment. Furthermore, so far no research investigating the associations between

various types of child maltreatment and health outcomes among the general

population has ever been conducted in Vietnam.

To respond to the compelling need for evidence on the child maltreatment issue in

Vietnam, in this project we conducted a school-based survey of various forms of

child maltreatment among school children from grade 7 to grade 11 (aged from 12-

18 years) in both urban and rural areas in Vietnam. Four different types of child

maltreatment were assessed: physical maltreatment, emotional maltreatment, sexual

abuse, and neglect. The effects of co-occurrence of these types of child maltreatment

3

on adolescents’ self-reported health risk behaviours, mental and physical health were

also explored. This study is among the first of this kind conducted in Asian countries.

On the whole, the study not only contributes evidence to child maltreatment research

in developing countries but also helps to raise awareness and develop culturally

appropriate measures for child maltreatment prevention and intervention in Vietnam.

1.2 Research aim and objectives Research aim

The primary aim of this research was to examine the nature and co-occurrence of

various forms of child maltreatment reported by Vietnamese school children from

grade 7 to grade 11 in both urban and rural settings and to determine the extent to

which such maltreatment experiences impact on self-reported health risk behaviours

and the physical and mental health of the children.

Research objectives

It follows that the objectives of the research were to:

1. Estimate the lifetime prevalence of sexual abuse, physical maltreatment,

emotional maltreatment and neglect as well as multiple type maltreatment rates,

experienced by school adolescents in one urban district and one rural district.

2. Identify risk factors for each form of child maltreatment from various

background variables including demographic characteristics, family

characteristics and environment.

3. Describe various health risk behaviours of school adolescents.

4. Measure physical and mental health of school adolescents.

5. Examine independent effects of each form of child maltreatment and potential

cumulative impact of co-occurrence of maltreatment on health risk behaviours as

well as on physical and mental health of these adolescents.

1.3 Outline of thesis

Chapter 1 has set the background and outlined the purpose of this study.

Chapter 2 reviews the literature related to a wide range of child maltreatment issues.

Initially, while acknowledging the complexity and difficulties of reaching a global

definition of child maltreatment, the review presents widely-used child maltreatment

definitions and classifications by researchers worldwide. The review provides

essential information for selecting the operational definition of child maltreatment to

be used in this research.

The chapter includes a review of estimated prevalence of child sexual abuse, physical

maltreatment, emotional maltreatment, and neglect reported in the international

literature. A wide range of risk factors and possible effects of each form of child

maltreatment and the co-occurrence of multiple types of maltreatment on the victims

are then explored in detail. As enormous child maltreatment research using different

samples have been published worldwide, for the purpose of our study, the review

mainly focuses on the studies among community or school-based adolescents and

early young adult samples. Key information about Vietnam and small body of local

research on child maltreatment is also presented. Based on the literature review, the

chapter ends by proposing the hypotheses of this study.

Chapter 3 The chapter begins by briefly considering significant methodological

issues of child maltreatment research. Then the research methods used for this study

and the main results of the pilot study, focusing on instrument development and

validation are described.

Chapter 4 reports the estimated prevalence of child sexual abuse, physical and

emotional maltreatment and neglect as well as the rates of maltreatment co-

occurrence among adolescents. Demographic variables, family characteristics and

family environment variables that emerged as significant risk factors for each form

of child maltreatment are presented.

Chapter 5 reports the rates of various health risk behaviours of adolescents. This

chapter also provides results of analysis of the associations between sexual abuse,

physical and emotional maltreatment, and neglect as well as between multiple-type

maltreatment and each health risk behaviour.

Chapter 6 estimates the relative effects of each form of child maltreatment and

cumulative effects of poly-victimization on depression, anxiety, self-esteem, and

general physical health of adolescents. Significant associations are also reported

between a wide range of background factors and depression, anxiety, self-esteem and

physical health.

Chapter 7 contains a discussion of the main research findings. The strengths,

limitations and the implications of this study are also discussed.

Chapter 2: Literature Review

2.1 Definition of child maltreatment

In 1999, the WHO Report of the Consultation on Child Abuse Prevention proposed

the following definition, which covers a broad spectrum of abuse (WHO, 1999):

Child abuse or maltreatment constitutes all forms of physical and/or emotional

ill-treatment, sexual abuse, neglect or negligent treatment or commercial or other

exploitation, resulting in actual or potential harm to the child’s health, survival,

development or dignity in the context of a relationship of responsibility, trust or

power. (p.15)

While this definition is quite broad, covering various aspects of abuse and neglect,

the vagueness and ambiguity surrounding the definition of this particular complex

problem still make it difficult to operationalise internationally. Awareness of cultural

factors therefore must remain high as these influence all aspects of the problem from

definitions of child abuse and occurrence to its effective prevention.

Behaviours towards children considered as abusive or neglectful vary and the

labelling of behaviours is a contentious issue. World Vision in partnership with the

International Society for the Prevention of Child Abuse and Neglect and Chapin Hall

Centre for Children, University of Chicago designed a five-country study,

interviewing community leaders, caregivers, and children to explore perceptions of

child maltreatment (Dorning, 2002). Despite some cultural differences, a wide range

of behaviours were consistently mentioned in defining child maltreatment by most

respondents and there were some common perceptions in behaviours considered

abusive in all five countries, namely Ghana, Kenya, Thailand, Brazil, and Romania.

However, there are also points of departure between Western and Eastern attitudes

7

on a number of issues closely related to child abuse, especially physical punishment

and emotional expression (Lansford et al., 2005; Michaelson, 2004). Some

definitions focus on the behaviours or actions towards the child while others consider

maltreatment takes place only if there is harm or threat of harm to the child (Dorning,

2002; Straus, Hamby, Finkelhor, Moore, & Runyan, 1998). Given this culturally

variability in the concept of child maltreatment, what definition used to research the

occurrence of different types of child maltreatment cross-culturally?

Within a broad definition of child maltreatment from WHO, a large body of literature

and research on different parts of the world has generally classified child

maltreatment into four major types: physical abuse, sexual abuse,

emotional/psychological abuse, and neglect (Browne, 2002; Clemmons, DiLillo,

Martinez, DeGue, & Jeffcott, 2003; Corby, 2000; D'Antonio et al., 1993; Dong,

Anda, Dube, Giles, & Felitti, 2003; Futterman Collier, McClure, Collier, Otto, &

Polloi, 1999; Goddard, 1996; Meadow & Bamford, 1997; Miller-Perrin & Perrin,

1999; Schwartz-Kenney, McCauley, & Epstein, 2001; Stephenson et al., 2006;

Wolfe, 1999; Zoroglu et al., 2003). In a group meeting of world experts organised by

the WHO and the Global Forum for Health Research, an extensive review and

discussion of different countries’ definitions of child maltreatment provided widely

accepted definitions of sub-categories of child maltreatment as given below (WHO,

1999).

• Physical abuse of a child is that which results in actual or potential physical harm

from an interaction or lack of an interaction.

• Sexual abuse is the involvement of a child in sexual activity that he or she does

not fully comprehend, that violates the laws or social taboos of society. Child

sexual abuse is evidenced by activity between a child and an adult or another

child who by age or development is in a relationship of responsibility, trust or

power, the activity being intended to gratify or satisfy the needs of the other

person.

• Emotional/Psychological abuse may include the failure to provide a

developmentally appropriate and supportive environment, and include acts that

8

have an adverse effect on the mental health and social development of a child.

Such acts include restriction of movement, denigrating, and threatening, scaring,

discriminating, ridiculing or other forms of hostile or rejecting treatment.

• Neglect is the failure to provide for the development of a child in all aspects such

as: health, education, emotional development, nutrition, safe living conditions etc

in the context of resources reasonably available to the family or caretakers and

causes harm or potential harm for a child.

The above definitions are sound in that they have provided a general framework for

investigation of child maltreatment internationally. The conduct of research on such

sensitive and complex subjects presents practical problems regarding clearly

identifying operational criteria for each type of child maltreatment. No single

definition is likely to be suitable for every purpose; rather it must reflect study

objectives and hypotheses. However, we can conceptualize different types of child

maltreatment experiences as a continuum of behaviours toward the child. Through

comprehensive review of the literature (see Appendix 1) a list of behaviours

commonly placed under each sub-category of child maltreatment has emerged as

follows:

• Physical maltreatment: frequently includes shaking, slapping, punching,

beating, kicking, tying, and burning.

• Sexual abuse: includes non-contact events such as talking in sexual way,

exposing private parts, forcing to watch sexual things, and contact events such

as touching or fondling, attempting to have any type of sexual intercourse and

penetration.

• Emotional/psychological maltreatment: The habitual verbal harassment of a

child by disparagement, criticism, threat and ridicule. Emotional or

psychological abuse includes behaviours that threaten or intimidate a child. It

includes threats, name calling, belittling and shaming.

• Neglect: Failure of caretakers to provide for a child’s fundamental needs

except in the context of unavoidable effects of living in poverty. Although

neglect can include children’s necessary emotional needs, neglect typically

concerns adequate food, housing, clothing, and medical care.

9

In sum, efforts have been made to provide definition and classification of child

maltreatment which can provide a conceptual framework for practitioners and

researchers in the field of child protection. Even though there have been ongoing

debates about cultural variation in different aspects of child maltreatment perception,

a continuum of adverse experiences which are commonly used by researchers to

examine the occurrence and effects of deferent types of child maltreatment has

emerged as generally accepted. Fergusson and Mullen (1999) provided very clear

discussion of these issues and strongly recommend that in order to describe the

extent and the severity of child maltreatment experiences in a systematic and reliable

manner, a list of behaviourally-specific questions should be used.

2.2 International prevalence of child maltreatment

There is wide variation in the estimated prevalence of child maltreatment. The

variation can be attributed to differences in the definition of maltreatment, study

populations, framing of questions about maltreatment, procedures used for collecting

data, the types of maltreatment and the response rate. It is also important to

emphasise that methodological factor only contribute some of the variance. Observed

differences in incidence between cultures, or over different times, may be genuine.

The research into child maltreatment prevalence published so far primarily assesses

sexual abuse and secondly physical maltreatment, and only a small body of extant

studies have assessed emotional maltreatment and neglect. While there are several

published studies reviewing epidemiological data on the prevalence of child sexual

abuse and methodological factors influencing the prevalence estimation (Dunne,

2002; Fergusson & Mullen, 1999; Gorey & Leslie, 1997), we are not aware of any

similar paper reviewing child physical and emotional maltreatment and neglect

prevalence. The reviews reported that the high rates of child sexual abuse are found

among clinical samples, which include participants such as attendees at psychiatric

and child guidance clinics, people coming from criminal justice systems, and

children coming to the attention of welfare agencies (Fergusson & Mullen, 1999).

Reviewing 13 child sexual abuse prevalence studies among female general

population samples and student samples, Dunne (2002) found the average prevalence

10

rates to be remarkably similar in these two types of sample (27.7% vs. 29.8%

respectively). He suggested that deviation from random population sampling per se

might not necessarily be the cause of the significant degree of prevalence variation

among studies. In an integrated review of 16 cross-sectional surveys among non-

clinical populations about child sexual abuse from North America, Gorey and Leslie

(1997) found definition of abuse and response rate had a profound effect (50% of the

prevalence variance) on these estimates. The higher the response rate and the

narrower the abuse definition the lower prevalence estimated. However, neither

sampling method, type of sample nor data collection method explained significant

proportions of the prevalence variation.

As mentioned earlier, the studies among clinical populations suggest higher

prevalence rates than maltreatment prevalence estimations among the general

population and student samples. As a result, it would be unreasonable to conclude

that these estimates from clinical samples fairly represent the problem in the general

population. For the purpose of this project therefore, the review will focus on studies

conducted among non-clinical samples, especially among young adults, university

and college students and school-based samples of adolescents.

Prevalence studies with community-based samples mainly rely on retrospective

reports by adults about their childhood experiences. The adult groups studied most

frequently include samples from the general population, college or university

students. There has been much less research on child maltreatment among

adolescents from school-based samples.

Child physical abuse/maltreatment (CPA)

Studies with young adults and older adults in the United States and other developed

countries reveal self-reported childhood physical abuse prevalence rates from 10% to

34% in males and 6% to 40% in females (Dube, Anda, Felitti, Edwards, & Croft,

2002; MacMillan et al., 1997; May-Chahal & Cawson, 2005; Meston et al., 1999;

Springer, Sheridan, Kuo, & Carnes, 2003). Studies in some Chinese societies and

11

other developing countries tend to yield higher rates of CPA. Apart from the

differences due to inconsistencies in study definitions and methodology, the

differences in prevalence of CPA between Western and Asian countries may be

mainly rooted in cultural attitudes towards physical punishment in child rearing.

Hahm and Guterman (2001) reviewed literature on CPA in South Korea and found

relatively high rates documented in recent studies. The authors listed 7 main studies

on CPA conducted during 1994-1998 with school children and/or parents as sample

populations and using Conflict Tactics Scale or modified versions of Conflict Tactics

Scale as study instruments. The results varied from 23.2% to 81.5% reporting

moderate violence and from 8.2% to 76.8% reporting severe forms of violence

including kicking, beating, throwing or threatening with a knife or a gun. In Hong

Kong, it has been shown in a recent survey among randomly selected parents of

children under the age of 16 that 46.1% of children were subjected to severe violence

and 52.6% subjected to minor violence during the preceding year (Tang, 1998).

A comparative study of school children’s experience of violence in China and Korea

found that family violence during the preceding year was experienced by 70.6%

Chinese children (42.2% minor, 22.6% serious and 5.8% no classification) and

68.9% Korean children (9.4% minor, 51.3% serious and 8.2% no classification)

(Kim et al., 2000). Another study in Hong Kong limiting the reported time to 3

months and using different violence classifications among a random sample of

secondary school students found different figures. According to this study,

prevalence rates of being beaten to injuries by family members in the past 3 months

was 1.1%, being beaten by parents for no apparent reason was 2.0%, corporal

punishment was 4.9%, and any of the above three was just 6.6% (Lau, Liu, Cheung,

Yu, & Wong, 1999).

Lau and colleagues (2005) used secondary data from a large-scale cross-sectional

survey among 95,788 secondary school students in Hong Kong to determine the

prevalence of physical maltreatment. Physical maltreatment was measured by two

indicators. First, indicators of students who had experienced corporal punishment by

12

their family members in the last 6 months were measured. Second, whether or not

respondents had been injured during a beating without provocation by parents in the

last 6 months were measured. Study results show that similar proportions (4.1%) of

males and females reported corporal punishment during the preceding 6 months.

Nearly three per cent (2.9%) of the sample reported being injured by family members

from a beating occurring without provocation, and this prevalence was slightly

higher in males (3.1%) than females (2.7%). The estimated prevalence of CPA in this

study corroborates those results revealed by the previously mentioned study by Lau

et al. in 1999.

A cross-cultural comparison of four post-communist bloc countries (Latvia,

Lithuania, Macedonia, and Moldova) with more than one thousand students aged 11-

14 years old was conducted between 1998 and 2000 (Sebre et al., 2004). In this

study, CPA was measured using the 10 physical abuse items of the Conflict Tactic

Scale measured during the past year. Respondents were identified as being physical

abused if they marked “sometimes”, “often” or “always” for any items or at least

“rarely” for the more severe items. Significant differences in the incidence of

physical abuse were noted across countries (Latvia: 17.4%; Lithuania: 26.0%;

Macedonia: 12.1%; and Moldova: 29.7%). The authors accounted for the variation in

CPA prevalence among countries in three ways. First, there are real differences in

overall parental behaviour. Second, CPA may be conceptualized differently by

students in these countries. Children may consider parent behaviours, viewed as

abusive by experts, as “normal” therefore not report these behaviours. Third, children

may differ in willingness to report their parent’s behaviours due to social-cultural

traditions and prohibition.

Recently, two studies on child maltreatment in Middle Eastern societies reported

remarkably different figures on prevalence of CPA. About ninety per cent of female

students aged 14-18 years old in a Bedouin-Arab in Southern Israel community had

experienced some act of CPA (Elbedour, Abu-Bader, Onwuegbuzie, Abu-Rabia, &

El-Aassam, 2006). In contrast, Stephenson and colleagues (2006) reported that the

prevalence of CPA among school adolescents (11-18 year olds) in Kurdistan

13

province, Iran was 38.5% at home and 43.3% at school (with male: 45% at home and

55.7 at school; female: 28.0% at home and 22.6% at school). Differences in research

definitions of CPA was one of the main reasons explaining the difference of reported

prevalence of these two studies. The latter study used a much narrower definition of

CPA with only two questions. The first question was a general screening item

regarding self-perception of physical abuse experience of the respondent asking

whether the child had ever been physically maltreated at home or school. The second

question asked about the degree of physical maltreatment including bleeding,

scratching, or bruising; broken bones; burning; tying; the need for medical care, if

children responding “yes” to the first question. The children who endorsed any of

these experiences were classified as CPA.

Very few researchers have attempted to study the prevalence of different forms of

child maltreatment across cultures. So far, cross-culturally comparable data on CPA

come from the World Studies of Abuse in the Family Environment (WorldSAFE)

project (Hunter & Bangdiwala, 2004). This was an international multi-site study,

conducted in Chile, Egypt, India and the Philippines. In these countries, a core

instrument has been used to survey population-based samples of mothers, aged 15-49

years about various discipline practices, including harsh punishment that might be

considered abusive. Table 2.1 presents the study results from four countries on

prevalence of self-reported parental abusive discipline. The findings are compared to

those from a national survey conducted in the United States using the same

instrument.

Clearly, harsh punishment is quite common in these countries. Parents in Egypt,

India and the Philippines more frequently reported harsh punishment of their children

than their counterparts in Chile and the United States. Recently, Lansford et al.

(2005) found significant difference in mother reported frequency of using physical

discipline in a cross-cultural study in 6 countries. The rank order from high to low

frequency of mother reporting using physical discipline was Kenya, India, Italy,

Philippines, China and Thailand. Appendix 1 documents the findings of some

14

childhood physical abuse prevalence studies worldwide with population-based

participants at adolescent and early adult ages.

Child sexual abuse/maltreatment (CSA)

Estimates of prevalence of childhood sexual abuse vary widely between studies

depending upon the operationalized definitions, study samples, the ways in which

data are collected, the age cut-off for childhood, and the age difference between

victims and perpetrators. Many studies among non-clinical samples of adults in the

United States (US) estimate self-reported childhood sexual abuse rates of 2.2 % to

29% in men (Ambuel, Butler, Hamberger, Lawrence, & Guse, 2003; Dong et al.,

2003; Scher et al., 2004) and 7% to 43% in women (Ambuel et al., 2003; Dong et al.,

2003; Scher et al., 2004; Walker et al., 1999; Wise, Zierler, Krieger, & Harlow,

2001).

Finkelhor (1994) reviewed more than 20 epidemiological surveys with large non-

clinical populations from the US, Canada and 19 other countries, including 10

national probability samples. The studies showed sexual abuse histories in at least

7% of the females and 3% of the males, ranging up to 36% of women in Austria and

15

29% of men in South Africa. Another review of reports from Europe indicated that 6-

36% girls and 1-15% boys under the age of 16 experienced some type of sexual

abuse (Lampe, 2002).

Various studies conducted in the US among school-based adolescents reveal CSA

rates ranging from 3 % to 8% of boys and 10% to 30% of girls (Bensley, Spieker,

Van Eenwyk, & Schoder, 1999; Grossman, Milligan, & Deyo, 1991; Harrison,

Fulkerson, & Beebe, 1997; Lodico, Gruber, & Diclemente, 1996; Riggs, Alario, &

McHorney, 1990). In contrast to North America, less research on the prevalence of

CSA has been conducted in Europe and other developed countries with school

samples. Two studies carried out in Switzerland and Sweden among school children

aged 17 or younger showed relatively different figures of 33.8% for girls and 10.9%

for boys in Switzerland whereas 11.2% for girls and 3.1% for boys in Sweden having

experienced at least one sexual abuse event. However, the latter study excluded peer

abuse in its CSA definition (Edgardh & Ormstad, 2000; Halperin et al., 1996). These

figures are higher than findings from another school-based sample conducted by

Martin et al. (2004) in Australia reporting 2.0% males and 5,4% females experienced

CSA. Importantly, the differences might be explained by variation in the question

used to assess sexual abuse. The two former studies used a list of sexual abuse events

while the latter used only one question “have you ever been sexually abused?”.

Studies conducted among adolescent samples in some Asian countries shows that

CSA’s prevalence seems to be at the lower point of the range in comparison to other

parts of the world. Diverse findings on CSA prevalence rates have been revealed in

several empirical studies with high school or college students carried out in China,

Hong Kong, and Malaysia. These studies used similar broad definitions of CSA

including non-contact and contact events however there were differences in the age

cut-off for events in childhood. The participants were asked to report their childhood

sexual experiences occurring before age 16 in China, 17 in Hong Kong, and 18 in

Malaysia studies. CSA rates ranged from 2.1 – 4% for boys and from 7 – 25% for

girls (Chen, Dunne, & Wang, 2002; Chen, Dunne, & Han, 2004; Singh, Yiing, &

Nurani, 1996; Tang, 2002). Of those studies, Chen et al. (2002) found the highest

16

rate of around 25% of high school Chinese female students subjected to any of ten

forms of CSA. However, non-penetrative forms accounted for the majority of the

cases.

A study among more than two hundred female school students in Israel revealed that

more than half of respondents (53.3%) reported experiencing at least one sexual

abuse event (Elbedour et al., 2006). Using a different definition of CSA (touching

and/or intercourse), Alikasifoglu and colleagues (2006) found that among nearly

2,000 Turkish female students (mean age: 16.3; SD: 1.05) 11.3% reported touching

sexual abuse, 4.9% reported forced intercourse, and 3.0% experienced both types of

CSA. Again, it is clear that due to the large differences in definition, data gathering

techniques, the wording of individual questions and cultural differences between

respondents in the ways they interpret the questions, it is impossible to establish

more precise conclusions about the prevalence of CSA. A more exhaustive summary

of studies that attempt to estimate childhood sexual abuse prevalence among

community-based adolescent samples from various countries is given in Appendix 1.

Child emotional abuse/maltreatment (CEA) and child neglect (CN)

Professionals working in the area of child abuse have found it extremely difficult to

operationally define CEA and CN. There is considerable uncertainty regarding legal

definitions. In comparison to CPA and CSA, child emotional abuse and neglect is

under-recognized. Behl et al. (2003) reviewed 2,090 articles pertained to child

maltreatment published from 1977-1998 in six specialty journals and found that the

major proportion of articles addressed specific types of child maltreatment were

32.7% for CSA, 20.2% for CPA, 9% for CN and only 4.2% for CEA. Most estimates

of CEA and CN prevalence have been obtained from clinical samples or case reports

(Jellen, McCarroll, & Thayer, 2001). There has been a dearth of figures based on the

general population in most countries.

17

So far, most epidemiological studies documenting rates of CEA and CN with

samples from the general population have been done in North America and some

other developed countries such as the United Kingdom. Again, rates vary

considerably depending on definitions, methodologies and samples recruited. Walker

et al. (1999) reported prevalence among women for CEA of 24%, prevalence of

physical neglect and emotional neglect were 12% and 21%, respectively. A study by

Dong et al. (2003) showed lower prevalence rates among a sample of adult health

plan members. Child emotional abuse was reported by overall 10.6% of the study

population with 13.1% of women and 7.6% of men reporting CEA. May-Chahal and

Cawson (2005) estimated CEA and CN prevalence using mid point score of seven

emotional dimensions defined on a continuum of behaviours and three level

definition of CN severity measured different neglect events. This study found that

among nearly three thousand young adults (18-24 year olds) randomly selected

throughout the United Kingdom, 6.0% reported CEA, 6.0% experienced serious

absence of care, 9.0% experienced intermediate level of neglect, and 2.0% reported

neglect at the level of cause of concern.

Studying a sample of high school students in Mpumalanga, a poor province in South

Africa, Madu (2001) found the considerably higher rate of CEA (35.3%) compared

to those reported in studies conducted in the developed countries mentioned above.

However, lower rate of CEA (26.9%) among South African university students was

also reported by the same author (Madu, 2003). The inconsistency of these two

prevalence rates in South Africa may stem from differences in socio-economic

backgrounds of the two samples.

Child emotional abuse prevalence also varied significantly among the four former

communist bloc countries indicating rates of 10% to more than 30% in a school-

based study (Latvia: 28.8%; Lithuania: 33.3%; Macedonia: 12.5%; and Moldova:

32.1%) (Sebre et al., 2004). Child emotional abuse and neglect prevalence at home

and school was examined in a school-based study in Iran (Stephenson et al., 2006).

Strikingly high rates of students reported experiencing at least one emotional abuse

18

event at home (female: 64.7%, male: 74.5%) and one neglect event at home (female:

71.1%, male: 86.5%).

International estimates of prevalence of CEA have emerged from the WorldSAFE

project (Runyan et al., 2002). Table 2.2 shows the findings of emotional punishment

from surveys across five countries in this project.

There is evidence to suggest that most CEA acts are more common in Egypt than

other study countries. The practices of threatening children with abandonment,

kicking the child out of the household, and being locked out of the house, however

vary greatly among the countries. Cultural factors seem to strongly influence how

parents choose emotional punishment strategies toward their children.

Unfortunately, research on CEA and CN with general population samples seems to

be neglected in most developing countries. It is therefore difficult to delineate a clear

picture on these problems. However, it is believed that the problems exist and are of

growing concern to policy makers, health workers, researchers, and the general

public (Hildyard & Wolfe, 2002; Jinadu, 1986). (Appendix 1 summarised several

recent studies on CEA and CN).

19

Multiple-type maltreatment (MTM)

The experience of child maltreatment is complex at the individual level, as a child

may suffer more than one form of maltreatment in a given abuse episode, or may

experience different forms of abuse at different times. Multiple-type maltreatment

refers to the co-occurrence of one or more forms of child maltreatment. It is

important to distinguish between individuals who have experienced only one

maltreatment form and those who have experienced two, three, or more types of

child maltreatment because of cumulative effects of MTM (Higgins & McCabe,

2001b). However, there are few research reports the prevalence rates of co-

occurrence of child maltreatment and almost all are conducted in developed

countries.

A growing body of empirical evidence shows that co-existence of more than one

form of maltreatment is not uncommon. Higgins and McCabe (2000a) examined the

co-occurrence of CSA, CPA, CEA, CN and childhood exposure to family violence

reported by a community sample of 175 Australian men and women. Overall, 43.4%

of participants reported experiencing more than one form of child maltreatment,

while 15.4%, 11.4%, 9.7%, and 6.9% of the total sample were classified as

experiencing two, three, four and five forms of maltreatment respectively. Moeller et

al. (1993) found a similar pattern among a large community sample in the US with

45% of the participants reporting two or three types of child maltreatment (i.e.,

physical, sexual, or emotional abuse). In a very large study among 8629 adult Health

Maintenance Organisation members in the United States, Dube et al. (2001)

examined 10 categories of adverse childhood experiences (ACEs) including

emotional, physical, sexual abuse, emotional and physical neglect, battered mother,

household substance abuse, mental illness in household, parental separation or

divorce, and incarcerated household member. Nearly forty per cent (38.1%) of all

participants reported having experienced more than one type of ACEs and over; 17%

of women and 11% of men reported four or more of these ACEs. In a survey of a

representative population-based sample in the metropolitan Memphis, US, Scher et

al. (2004) found a lower proportion of adults (13.5%) who met criteria for

20

experiencing more than one form of child maltreatment classified as emotional,

physical, sexual abuse, emotional and physical neglect.

To date the only school-based study reporting the prevalence of MTM including 4

types (CPA, CEA, CSA, and CN) of child maltreatment was conducted in Turkey

(Zoroglu et al., 2003). This study involved 862 students (mean age: 15.9; SD: 1.8) of

four high schools in Istanbul. Nearly fourteen per cent (13.8%) of respondents

reported having experienced two or more types of child maltreatment, of which 8.7%

reported two types, 3.8% three types and 1.3% all four forms of trauma.

Although estimates vary, it is nevertheless clear that a significant proportion of

individuals experience multiple forms of child maltreatment. Given the accumulating

evidence of co-occurrence of maltreatment types, it appears important for researchers

to explore and document co-existence among different forms of maltreatment and to

examine the possible cumulative effects of MTM on health and well-being

(Clemmons et al., 2003; Kinard, 1994; Simpson & Miller, 2002).

Overall, the main conclusions from reviewing research worldwide on prevalence of

child maltreatment are:

First, child maltreatment has been found in all countries where it has been measured

(Fergusson & Mullen, 1999). However, the prevalence of child maltreatment varies

widely from study to study depending largely on research definitions, sample

characteristics, response rate (Gorey & Leslie, 1997) and cultural characteristics

(Meston et al., 1999). Definitional and methodological inconsistencies, differences in

study population and timing of investigation across epidemiological studies on child

abuse have made it extremely difficult to draw firm conclusions regarding the rates

of different forms of maltreatment as well as the extent to which these forms have

co-existed in the general population (Simpson & Miller, 2002).

21

Second, most child maltreatment prevalence is reported from the United States and

other developed countries. There is a dearth of child maltreatment research in

developing countries in general and in Asian developing countries in particular.

Third, despite the need for information on all types of child maltreatment and

multiple types of maltreatment, most research worldwide mainly focuses on CSA

and CPA. As a result, relatively little is known about CEA, CN and MTM.

2.3 Risk factors for child maltreatment

Why does child maltreatment occur? This is a complex question. A variety of

theories have been developed to answer this question and research has generated

various frameworks for observing, understanding, explaining, and intervening in

child maltreatment. Discussed below are the main theories as to why child

maltreatment occurs. Each theory emphasizes particular aspects, and none provides,

on its own, comprehensive account.

Attachment theory (Rutter, 1982) emphasises that nature and quality of attachment

between parents or other caretakers has considerable impact on ability to protect the

child from aggression or neglect. A failure of attachment may therefore not only be

consequence of abuse, it may contribute to it. Poor infant-caretaker attachment must

be considered as a risk factor for child maltreatment. The theory focuses on the

personal dynamics of attachment, rather than stress factors such as unemployment,

marital discord or financial difficulties. This theory focuses on personal

relationships, rather than social circumstances.

Psychopathology theories (Miller-Perrin & Perrin, 1999) propose that various forms

of child maltreatment are committed by individuals who are seriously disturbed by

some types of mental illness or personality disorders. However, many experts argue

that psychopathology is observed in only a small percentage of child abuse

perpetrators (Groff & Hubble, 1984; Williams & Finkelhor, 1990). Yet, from the

psychological perspective (Wilson-Oyelaran, 1989) it is presumed that the

22

psychologically malfunctioning parents or caretakers may be potential child

maltreatment offenders. Those people can be identified by a series of contributory

characteristics such as low self-esteem, a history of childhood abuse and intolerance

for frustration and criticism.

Social learning theory (Elliott, Thomas, Chan, & Chow, 2000; Miller-Perrin &

Perrin, 1999), a widely accepted explanation of how socialization plays a role in

child maltreatment, emphasizes that child abuse is a problem not derived from

personality traits or lack of attachment, but through inappropriate reinforcement or

modelling. Modelling is a process in which a person learns social and cognitive

behaviours by simply observing and imitating others. Social learning theory rests on

several observations. First, maltreatment tends to perpetuate itself from one

generation to the next (Frias-Armenta, 2002; Morton & Browne, 1998; Newcomb &

Locke, 2001); second, a large number of studies have successfully linked exposure to

violence in childhood, either directly or through observation, to violence in

adulthood (Bensley, Van Eenwyk, & Wynkoop Simmons, 2003; Williams &

Finkelhor, 1990).

Sociological models (Corby, 2000), also known as socio-cultural or environmental

models (Browne, 2002), focus on the social environment and other cultural patterns

which would interfere with parents’ or caregivers’ ability to cope with the day-to-day

environment. Within these models, child maltreatment is examined in terms of the

social context in which it occurs. Factors associated with abuse from this perspective

include: cultural attitudes toward violence; social stress arising from inadequate

housing, unemployment, family size; social isolation, and other financial stresses and

pressures.

Maltreatment is multifaceted and children in families are embedded in complex and

interrelated social systems that affect conditions within families (Macdonald, 2001).

Each of these theories has explanatory power with a restricted range of variables, but

they are not able to successfully integrate divergent viewpoints and provide a holistic

23

framework for arranging a large body of knowledge about the causes and

perpetuation of the problem.

A broader, more comprehensive model can be found in the ecological mode. This is

the most widely adopted model, providing a multidimensional perspective and helps

to understand the multifaceted nature of child maltreatment (Belsky, 1993; Corby,

2000; Hecht & Hansen, 2001; Korbin, 2003; Krishnan & Morrison, 1995; , 2002;

Leventhal, 2003; Wilson-Oyelaran, 1989). The ecological model of child

maltreatment has origins in models for human development; in which children are

seen to live within a series of interconnected systems conceived as ever widening

concentric circles or inter-nested spheres. This model has been used to conceptualise

the problem as a multifaceted phenomenon based on an interplay between personal,

situational and socio-cultural factors. These factors are nested in four different levels

labelled from the innermost to the outermost as the individual, micro-system:

relationship or family, the exo-system: community, the macro-system: societal

(Ellsberg, Pena, Herrera, Liljestrand, & Winkvist, 2000) (Figure 2.1).

Figure 2.1: Ecologically integrative model of child maltreatment

Adapted from: Krug et al. (2002)

A large body of studies has examined the risk factors of CSA and CPA while CEA

and CN have received comparatively little research attention (see Black et al.). While

no specific causes definitively have been identified leading parents or caregivers to

24

abuse or neglect children, epidemiological research conducted over the past four

decades suggests that some factors belonging to different layers of the model are

fairly consistent over a range of contexts. Children within families and environments

in which these factors exist have a higher probability of experiencing maltreatment.

However, it is important to note that a risk is not a certainty. The factors mentioned

below may be only statistically associated and not causally linked.

Individual level

A number of characteristics related to child and adult factors may be associated with

risk of maltreatment: for example, characteristics of the child (such as gender, age,

temperament, disabilities etc); adult attitudes, attributions, and cognitive factors;

prior history of abuse; alcohol and drug abuse; and demographic factors (such as

young marital age, marital status, and family size) (Black, Smith Slep, & Heyman,

2001; Brown, Cohen, Johnson, & Salzinger, 1998; Dietz, 2000; Krishnan &

Morrison, 1995; Madu, 2003; Madu & Peltzer, 2000; Moore, 1992; Paavilainen,

Astedt-Kurki, Paunonen-Ilmonen, & Laippala, 2001; Salter et al., 2003; Schumacher,

Smith Slep, & Heyman, 2001).

Child factors

With any type of child maltreatment, research shows that victims may possess certain

characteristics associated with increased risk for child abuse. However, these factors

should not be taken as evidence that these victims cause the maltreating behaviours

to which they are subject.

Gender: There are significant gender differences in risk of some forms of abuse and

neglect, especially child sexual abuse. The literature on child maltreatment among

adolescent community-based samples (see Appendix 1) shows that there is no clear

pattern of gender differences in CEM and CN. However, boys seem to be at risk of

being physically abused more than girls (Benbenishty et al., 2002; Hibbard,

Ingersoll, & Orr, 1990; Lau, Chan, Lam, Choi, & Lai, 2003; Meston et al., 1999;

25

Youssef, Attia, & Kamel, 1998a, , 1998b; Zoroglu et al., 2003). Conversely, girls are

more likely to be victims of sexual abuse than boys; this essentially reflects the fact

that they account for about 60% - 70% of the child sexual abuse victims (Chen,

Dunne et al., 2004; Edgardh & Ormstad, 2000; King et al., 2004; Pedersen &

Skrondal, 1996; Singh et al., 1996; Tang, 2002). However, recent studies in different

cultures among college and school-based samples have shown unexpected

equivalence in the rate of CSA among boys and girls (Haj-Yahia & Tamish, 2001;

Madu & Peltzer, 2000). Interestingly, a study conducted by Zeira et al. (2002) on

sexual harassment experiences of Arab and Jewish students occurring at a school

setting in Israel found sexual harassment to be much more common among boys than

girls in all measures. These findings suggest different patterns of maltreatment

vulnerability for boys and girls, which have implications for further research.

Age: National Incidence Studies in the United States and population-based studies

have consistently found that gender and age are related to risk of abuse

(HealthCanada, 2001; Jones & McCurdy, 1992; Lau et al., 2005; Windham et al.,

2004). Toddlers, preschool children and young adolescents are the most frequent

victims of physical and emotional maltreatment. Although child physical abuse

affects a sizeable proportion of all age groups, the highest rate of injuries due to

physical abuse is found among older children (12-17 years of age), probably because

of increasing parent-adolescent conflict. Neglect may occur more often in the early

childhood with incidence declining with age (Belsky, 1993). In contrast, sexual

abuse is relatively constant from age 3 onwards, with children’s vulnerability from

early preschool years throughout childhood. The mean age of onset of sexual abuse

appears to be about 11-12 years, and this has been reported by studies in both

Western and Asian cultures (Chen, Dunne, & Han, 2006; Kogan, 2004; Oaksford &

Frude, 2001; Tang, 2002).

Disabilities: Generally, children who have special needs, including children with

disabilities and children with chronic illness or with difficult temperaments, low birth

weight/small for gestational age may be at greater risk of maltreatment (Black,

Heyman, & Smith Slep, 2001a; Brown et al., 1998; , 2002; Macdonald, 2001;

26

Windham et al., 2004). A large population based epidemiological study among

50,278 participants from 0-21 years of age conducted by Sullivan and Knutson

(2000) in the United States showed that overall rate of maltreatment among children

who had an identified disability for which they were receiving special education

services were more than three times more likely to be abused than were children

without an educationally relevant disability. In addition, the study also revealed that

children with a behaviour disorder or language impairment and mentally retarded

children are among much higher risk groups of being abused than children with

visual impairments, learning disabilities or autism.

Adult factors

Research also shows that adult factors potentially contribute to maltreatment. Over

the past decades a number of the characteristics of child maltreatment perpetrators

have been documented.

Demographic factors: Demographic factors are among the most common

variables studied as potential risk factors for different forms of child maltreatment.

All researchers are emphasising that most demographic variables are markers, not

causal, variables. Demographic variables influencing risk of child maltreatment may

include age, gender, ethnicity, religion, education, employment status, socio-

economic status, marital status, and size of family.

Black et al. (2001a) reviewed studies on risks of CPA and found that several

perpetrator demographic variables including young maternal age, low parental

education, mother’s employment status (unemployment or part-time job) and length

of residence of less than 14 years in a community were significantly associated with

minor and/or severe CPA. However, parents’ age was the only variable that had a

medium effect size. Mother’s age was also found to be a significant risk factor of

physical maltreatment in a female school adolescent sample of the Bedouin-Arab

community in Southern Israel. The older the mother, the less likely the girl was to be

subjected to physical abuse (Elbedour et al., 2006).

27

The relationships between perpetrators of CSA and demographic factors have been

explored in a large body of literature and a number of risk factors have emerged.

Finkelhor and Baron (1986) reviewed community studies and found that a child is at

higher risk of sexual abuse when he or she lives without one of the biological parents

or the child reports having a stepfather. A study among high school students in

grades 9 and 10 in three schools in Northern Province South Africa found that three

demographic factors proved to be significant discriminators of childhood sexual

abuse: ethnicity (not Northern Sotho), mother employed at above the level of a

labourer, and having a stepparent present during childhood (Madu & Peltzer, 2000).

Calculating effect sizes for several child sexual abuse studies in the United States,

Black et al. (2001) noted that moderate to strong effect sizes were found for

perpetrators who were less educated, poorer, and from outside the child’s family.

As far as child emotional abuse and neglect are concerned, according to Schumacher,

Smith Slep, and Heyman (2001) the only demographic variable playing a role as a

risk factor for child neglect with moderate or strong effect size was fertility (greater

number of live births, more pregnancies, and more unplanned conceptions). No

socio-demographic risk factors for child emotional abuse were found to have

moderate effect sizes (Black, Smith Slep et al., 2001). However, several studies

conducted in Western countries have found that low-income families, younger

parents and Asian ancestry also significantly increased the potential risk of neglect

(Chaffin, Kelleher, & Hollenberg, 1996; Jones & McCurdy, 1992; Meston et al.,

1999; Sedlak, 1997). Family income and ethnicity are also reported to be

significantly related to child emotional maltreatment (Meston et al., 1999; Sedlak,

1997).

Personality and adjustment factors: No set of characteristics or personality

traits has consistently been associated with maltreatment by parents or caregivers

(Belsky, 1993). Comprehensive reviews indicate that studies of underlying

personality traits have been unable to identify clear patterns associated with child

maltreatment (Wolfe, 1985). In contrast, Friederich and Wheeler (1982) argued that

there is a considerable amount of evidence that personality does play a role as a

28

determinant of child abuse. Various reviewers of the relevant literature draw

different conclusions regarding the role of personality and psychological resources.

This may arise because of the inconsistencies apparent in the available data.

However, recent studies seem to be more consistent in reporting some adjustment

factors in those who are physically abusive or neglectful such as low self-esteem,

more emotionally reactive and avoidance-focused problem-solving, stressful life

events and parenting stress, emotional distress, loneliness, anxiety, depression,

interpersonal problems (Black, Heyman et al., 2001a; Brown et al., 1998;

Schumacher et al., 2001)

History of maltreatment: Childhood abuse history appears to strongly influence

subsequent parenting. Individuals with poor parental experiences or those who did

not have their own needs met in childhood may find it very difficult to meet the

needs of their own children.

Child maltreatment studies have commonly found that some parents or caregivers

maltreated as children are at higher risk of abusing their own children or having

abused children (Finkelhor, Moore, Hamby, & Straus, 1997; Hemenway, Solnick, &

Carter, 1994; Ozturk Ertem, Leventhal, & Dobbs, 2000). One study investigated the

relationship between parent’s history of prior sexual victimization in a nationally

representative sample (Finkelhor et al., 1997). Parents were interviewed about their

sexual victimization experiences in childhood with two items (e.g. “before the age of

18, were you ever forced to have sex by an adult or older child, including who was

member of your family, or outside your family?”). The result shown that parents’

history of child sexual abuse was strongly associated with having a sexually abused

child (odds ratio = 10.2). Black and colleagues (2001a) reviewed child physical

abuse studies, which have the richest risk factor research literature for any form of

child maltreatment, and found support for the concept of intergenerational

transmission of child physical abuse.

Substance abuse: Parental substance abuse is reported to be a contributing factor

in between one- and two-thirds of cases of child maltreatment that reach the US child

29

welfare system (Magura & Laudet, 1996) and among court samples (Murphy et al.,

1991). Research provides ample empirical evidence for the link between parental or

caregiver substance abuse and increased risk for all forms of child maltreatment

(Chaffin et al., 1996; Dube et al., 2001; Famularo, Kinscherff, & Fenton, 1992;

Jaudes, Ekwo, & Van Voorhis, 1995; Kelleher, Chaffin, Hollenberg, & Fischer,

1994; Walsh, MacMillan, & Jamieson, 2003; Windham et al., 2004). For example, a

retrospective study of maltreatment experience in Chicago found children whose

parents misused alcohol and other drugs were almost three times more likely to have

been abused and more than four times more likely to be neglected than children of

parents who did not misuse substances (Jaudes et al., 1995). A recent comprehensive

population survey among more than 8000 participants in Canada (Walsh et al., 2003)

reveals that prevalence of physical and sexual abuse was significantly higher, with

more than two times increased risk among those reporting parental substance abuse

histories. There was a trend toward risk increasing with only parental, only maternal

and both parent substance abuse, respectively. A longitudinal study concerned with

the sequelae of parental substance abuse among Child Protective Service cases

closed after investigation found parental substance abuse greatly increases the

likelihood of poorer family functioning and re-reports for maltreatment to the Child

Protective Service agencies (Wolock & Magura, 1996).

Substance abuse can interfere with a parent’s mental functioning, judgment,

inhibitions, and protective capacity. Parents significantly affected by the use of drugs

and alcohol may neglect the needs of their children, spend money on drugs instead of

household expenses or get involved in criminal activities that jeopardize their

children’s health and safety. Additionally, studies suggest that substance abuse can

influence parental discipline choices and child-rearing styles (Magura & Laudet,

1996).

Knowledge and attitude toward child development: Negative attitudes and

attributions about a child’s behaviour and inaccurate knowledge about child

development may play a contributing role in child abuse (Dukewich, Borkowski, &

Whitman, 1996; Zuravin & Taylor, 1987). For example, Dukewich et al. (1996)

30

found maternal knowledge and expectancies about child development are more

predictive of abuse potential than is maternal psychological adjustment among

adolescent mothers. Other studies have also found that mothers who physically abuse

their children have both more negative and higher than normal expectations of their

children, as well as less understanding of appropriate developmental norms

(Twentyman & Plotkin, 1982; Williamson, Borduin, & Howe, 1991).

Relationship level (micro-system)

Relationship level factors associated with increase risk of child maltreatment include:

family environment; parenting styles; interactions among family members such as

anger; conflict; and social isolation (Bagley & Mallick, 2000; Black, Smith Slep et

al., 2001; Coohey & Braun, 1997; Gracia & Musitu, 2003; Jones & McCurdy, 1992;

Kasim, Shafie, & Cheah, 1994; Kellogg, 2002; Moore, 1992; Schumacher et al.,

2001). While these factors alone may not directly cause maltreatment, they

frequently contribute to negative patterns of family functioning.

Domestic violence has been reported as a risk factor at the micro-system level.

Strikingly, Osofsky (2003) noted that in 1990 the rates of physically abused and

neglected children in homes where domestic violence occurs weree 15 times higher

than the national average in the United States. According to published studies, in 30

to 60 percent of families where spousal abuse takes place, child maltreatment also

occurs (Appel & Holden, 1998; Edleson, 1999). Children in violent homes may

witness parental violence, may be victims of physical abuse themselves, and may be

neglected by parents who are focused on their partners or unresponsive to their

children due to their own fears.

A cohort study among married couples with children having at least one spouse on

active duty in the US Army during 1989-1995 reported that families with identified

spouse abuse were 5 times as likely as families without identified spouse abuse to

have a subsequent substantiated case of child abuse. After adjusting for rank of

soldier and parental age, families with spouse abuse were still twice as likely to have

31

a report of child abuse compared to other military families (Rumm, Cummings,

Krauss, Bell, & Rivara, 2000).

McGuigan and Pratt (2001) conducted a longitudinal study investigating the effects

of domestic violence during the first 6 months of child rearing on 3 forms of child

maltreatment (CPA, CEA and CN) up to the child’s first 5 years. The logistic

regression models established a significant relationship between domestic violence

and physical abuse, emotional abuse and neglect. Furthermore, beyond the effect of

known risk factors, domestic violence during the first 6 months of child rearing more

than tripled the likelihood of physical abuse and more than doubled the likelihood of

emotional abuse and neglect occurring during the child’s first 5 years.

This pattern was also found with child physical abuse of spouse-abusing parents in a

study of a large and nationally representative sample of American couples conducted

by Ross (1996). The study shows that marital violence is a statistically significant

predictor of child physical abuse after controlling for five demographic variables

(age of the respondent; age of selected child; socio-economic status of the family;

race of the respondent; and gender of the child), and corporal punishment of the

respondent as a teenager. The possibility of physical child abuse increases in

accordance with the amount of the violence against a spouse.

Very little research in developing countries has examined the risk factors for child

maltreatment at the micro-system level. Recently, a study conducted in Iran among

school adolescents has shown that quality of parental relationship was one of several

factors significantly associated with all types of child maltreatment examined (CPA,

CEA and CN) after controlling for other factors, including child’s age, region,

gender, birth order, school performance, mother’s education and employment, and

other household members’ use of addictive substances (Stephenson et al., 2006).

Odds of reporting physical maltreatment, emotional maltreatment, and neglect

increased with the severity of conflicts between parents. Relative to children whose

parents had no conflicts, children whose parents had any form of conflict reported

greater odds of physical maltreatment (less severe conflict OR = 3.46 and severe

32

conflict OR = 5.67), emotional maltreatment (less severe conflict OR = 3.53 and

severe conflict OR = 7.14), and neglect (less severe conflict OR = 2.07 and severe

conflict OR = 3.35) at home.

Community level (exo-system)

The third level includes the community contexts in which social relationships are

embedded, such as workplaces, neighbourhoods, school and peer groups. It is

important to determine the extent to which these factors are correlated with being a

victim or a perpetrator of abuse. Although interest in community/neighbourhood

influences on child maltreatment has increased recently, research seeking to uncover

the relationship between this level and child maltreatment has lagged behind research

into individual and family correlates. There is consensus that growing up in

neighbourhoods with high levels of unemployment, concentrated poverty, excessive

numbers of children per adult resident, and high population turnover are associated

with higher risk than that for children from wealthier and more stable communities.

This holds true for severe CN, CEA and CPA as well as CSA victimization (Coulton,

Korbin, & Su, 1999; Coulton, Korbin, Su, & Chow, 1995; Hadi, 2000; Hunter, Jain,

Sadowski, & Sanhueza, 2000; Korbin, Coulton, Lindstrom-Ufuti, & Spilsbury, 2000;

Molnar, Buka, Brennan, Holton, & Earls, 2003; Schumacher et al., 2001).

It is not clear why socio-economic characteristics of neighbourhoods are correlated

with child maltreatment. Attributes of the individual families living in a

neighbourhood and characteristics of the neighbourhood have contributed to the

variation in different forms of child maltreatment. Distinguishing different factors is

complex in child maltreatment research (Korbin, 2003). Most contextual studies do

not investigate multilevel factors. For example, they may focus on neighbourhood

features without incorporating family factors.

A recent study in the US examined whether differences among neighbourhoods on

parent-to-child physical aggression remain significant after family characteristics are

taken into account. This study used a unique study design incorporating data from

33

individuals and families living in 80 diverse neighbourhoods in Chicago (Molnar et

al., 2003). The study found differences in parent-to-child physical aggression

between families are greater than differences between neighbourhoods, based on

intraclass coefficients of .54 versus .02 respectively. No other multilevel study exists

therefore, it is suggested that further research on the multidimensional nature of child

maltreatment is needed using a clear definitions of neighbourhood and community.

Societal/ Structural level (macro-system)

The final level of risk factors includes the larger societal factors affecting the

occurrence of child maltreatment. Factors thought to be influential are dominant

cultural views and attitudes permeating the society at large such as laws, health,

educational systems, social and economic policies, and cultural norms (for instance,

norms that give priority to parental rights over child welfare, norms valuing boys

over girls etc.) (Ferrari, 2002; Johnson, 2002; Kim et al., 2000; Schumacher et al.,

2001). Krug et al. (2002) suggested the factors at this level as follows but to date

they have not been investigated as risk factors for child maltreatment in most

countries.

• The role of cultural values and economic forces;

• Inequalities related to gender and income;

• Cultural norms regarding gender role, parent-children relationship;

• Child and family policies;

• The nature and extent of health care system for infants and children;

• The strength of the social welfare system;

• The nature and extent of social protection and the responsiveness of the criminal

justice system;

• Larger social conflicts and war.

In summary, the value of ecological theory for child maltreatment lies in its capacity

to generate perspectives accommodating the influence of environmental context.

Before applying this model, researchers tended to confine their analysis of

34

environmental influences in close proximity to the child only. The ecological

model’s strength lies also in its ability to build a bridge between the fields of

psychology and sociology accounting for multilevel risk factors from individual to

societal levels.

An ecological model, like any other theory, is far from perfect. An ecological theory

is unable to depict how and why certain influences become powerful and come to

dominate the ecological system in certain circumstances. Additionally, the

interactions among these levels and factors are poorly understood and further in-

depth longitudinal research is required.

2.4 Consequences of child maltreatment

Child maltreatment is a heinous act. These acts are not only hurtful at the time they

occur; they are also detrimental to the child’s growth and development and may

affect their entire life and the lives of following generations (Walker et al., 1999).

Multiple, varied and substantial are terms that can be used to describe the effects of

childhood maltreatment on its victims. Multiple means that a wide array of

symptoms can emerge from maltreatment. Varied, since there is no clear or

consistent set of victim responses associated with the severity or type of

maltreatment. Substantial is used because childhood maltreatment may alter the

course of the victims’ lives in negative ways.

Among the most common types of research conducted to assess the effects of child

maltreatment are retrospective studies with or without comparison groups, follow-up

testing of maltreated and non-maltreated groups among various clinical samples, or

population-based samples including university students, school students and adults in

the general population. Variation exists across studies in the definition of child

maltreatment as well as the length of time elapsed from the time of the maltreatment

occurred.

35

Child fatality and burden of ill health

Children die from maltreatment in all countries in the world. However, accurate

statistics are difficult to find. In the United States, New Zealand and Australia

(among others), there are multi-disciplinary death-review teams that analyse the

causes of child deaths. The reliability of these data varies depending upon the

definitions, diligence, and data organisation. Child abuse was the second leading

cause of death in children in the US (Johnson, 2002). The national estimate of the

child abuse and neglect fatality rate in the US in 2004 was 2.03 per 100,000 children

and the youngest children suffered the highest rates of fatalities (Child maltreatment

2004). In New South Wales, Australia, 2.9% of deaths in children aged 1-17 years

were found to be due to homicide or non-accidental injury in 1988-1999. Between

1991 and 2003, 112 children and young people died from homicide, fatal assault

and/or neglect in Queensland, Australia. The fatalities rates have fluctuated from

year to year of approximately 0.3 to 1.7 per 100,000 (Annual Report Deaths of

children and young people Queensland 2004-05). However, one study conducted by

US Centre for Injury Control found that 85% of the deaths from child abuse in the

United States were recorded as due to other causes (Johnson, 2000). A study in New

Zealand reviewing reported death cases of children 16 years of age or under during

the period 1978-1987 revealed the same pattern: fatal child abuse is substantially

under-diagnosed in official sources of mortality data (Kotch, Chalmers, Fanslow,

Marshall, & Langley, 1993). Therefore such figures of child maltreatment fatalities

need to be treated with caution.

Survivors of child maltreatment often suffer from health problems both short term

and long-term. Some consequences can be easily observed in the form of physical

trauma such as bruises and welts, burns and scalds, fractures, and other physical

injuries. Keshavarz and colleagues (2002) found in their study that bruises were the

most frequently observed injury in 25% of cases, reported for child abuse from 1996-

1998, hospitalised at a New York metropolitan Paediatric Emergency Department.

36

Recently, a study in the US evaluating cause of injury and patient outcomes in young

children with abdominal injuries reported that among 927 cases of children aged 0-4

years extracted from the National Paediatric Trauma Registry, child abuse accounted

for 15.75%. Additionally, patient outcomes were more severe in abused children.

Child abuse is independently associated with a 6-fold higher rate of in-hospital

mortality compared to falls caused by other childhood activities (Trokel, DiScala,

Terrin, & Sege, 2004).

Furthermore, researchers and professionals working in this field from different parts

of the world have not only documented data on mortality and easily observable

physical injuries but also examined the long-term effects of child maltreatment.

Examples include studies finding that abuse survivors are sick more often and more

likely to seek health care (Arnow, Hart, Hayward, Dea, & Barr Taylor, 2000;

Mammen, 1996). McCauley and colleagues (1997) reported the various symptoms

were significantly related to a history of childhood physical or sexual abuse in

women in primary care practices: nightmares, back pain; frequent or severe

headaches, pain in the pelvic, genital, or private areas, eating binges or self-induced

vomiting, frequent tiredness, problems sleeping, abdominal or stomach pain, vaginal

discharge, breast pain, choking sensation, loss of appetite, problems urinating,

diarrhoea, constipation, chest pain, face pain, frequent or serious bruises, and

shortness of breath. Others studies also noted that adult subjects who suffer multi-

types of adverse childhood events are at increased risk of wide range of health

problems including cancer, stroke, diabetes, hepatitis, ischemic heart disease, chronic

pain syndromes, binge eating disorder (Grilo & Masheb, 2002; Lampe et al., 2003).

There is also ample evidence that abuse in childhood is associated with an increased

incidence of adult mental health problems such as depression, anxiety, anger, self-

esteem, fear, personality disorder and sexual dysfunction (Frias-Armenta, 2002;

Current methods of collecting statistics on health and mortality are not adequate

measures of the burden of disease and ill health resulting from child maltreatment

(Djeddah, Facchin, Ranzato, & Romer, 2000). It is estimated, however, that the

burden of ill health caused by child abuse accounts for a significant portion of the

global burden of disease (WHO, 1999).

Over the past decades the correlations between childhood maltreatment, especially

CSA and CPA, and a wide range of adverse adult health outcomes have been well

established (Fergusson & Mullen, 1999; Springer et al., 2003). For the purpose of

this project, the following section will focus on reviewing the literature on common

child maltreatment effects according to four types of child maltreatment and the co-

occurrence of child maltreatment mainly among community-based adolescent and

young adult samples. The intention is not to be exhaustive; as such review would be

very lengthy. Rather, the aim is to illustrate the diversity of problems associated with

each form of maltreatment. Then, the collective pattern is summarised in Table 2.3 to

show the similarities and differences in possible outcomes for each type of abuse.

The review in the remainder of this chapter is limited to community-based studies in

developing countries. In this respect, the collection of research is considerably

exhaustive. Occasionally, studies from the United States and other western countries

are cited, usually because there is no comparable study in developing countries. A

more exhaustive compilation of studies worldwide is given in Appendix 2.

Physical maltreatment consequences

Physical health

Physical maltreatment can vary from minor to severe and in extremely severe cases it

can cause fractures, brain injury or even death. However, when studies conducted

among population-based samples consider the initial impact of physical maltreatment

on children then it will be the immediate pain and suffering and medical problems

caused by the physical injury. A school based study with more than 3,000

adolescents (13-19 year olds) in Hong Kong found more than 1 per cent of the

38

adolescents reported being beaten to injury by family members in the preceding 3

months (Lau et al., 1999). More recently a large-scale study among more than 90,000

secondary students also in Hong Kong estimated relatively similar rate of

respondents (2.9 %) who reported being beaten to injury by family members during

the preceding 6 months (Lau et al., 2005). Perkins and Jones (2004) reported that

20.1% of students from a large-scale school based survey (16,313 adolescents from

43 public schools in Michigan, the United States) conducted in 1993-1994, had ever

experienced physical abuse from adults causing a scar, black and blue marks, welts,

bleedings, or broken bones. The large difference in figures from Hong Kong and the

US may be mainly due to the differences in assumption of physical maltreatment

time and perpetrators.

Regarding physical health consequences of physical maltreatment at home (Youssef

et al., 1998a) and in school settings (Youssef et al., 1998b), Youssef and colleagues

found striking results from a school-based study with more than two thousands

students enrolled in secondary and high public schools in Alexandria, Egypt during

the scholastic year 1996-1997. Among 37.5% students who reported having physical

maltreatment at home, 25.5% had experienced inflicted physical injuries including

bumps and contusions (61.4%), wounds (53.3%), fractures (5.7%), loss of

consciousness (6.7%), concussion (0.5%), and loss of vision in one eye (0.5%). More

than one fifth of the injury cases reported seeking medical care. In school settings,

the consequences of physical maltreatment by teachers were even worse. More than

one thousand boys (79.9%) and five hundred girls (61.5%) reported having

experienced physical maltreatment at school during the scholastic year. The

estimated prevalence of inflicted physical injuries among reported physical

maltreatment cases at school was 26.5% for boys (bump, contusions: 67.4%,

wounds: 40.4%, fractures: 7.1%, loss of conscious and concussion: 2.1%) and 18.5%

for girls (bumps or contusions: 72.6%, wounds: 30.5%, fractures: 6.3%).

In Hong Kong, Lau and colleagues (1999) found much lower rate (1.1%) of

secondary school students reported having been injured due to being beaten by

family member in the proceeding 3 months in comparison with Egyptian students.

39

Additionally, the authors also found an association between physical maltreatment

and other physical health consequences. Students who had experiences of physical

maltreatment by family members during the proceeding 3 months were generally

more likely to report somatic conditions, asthma, epigastric pain, dizziness,

headache, burn, cuts or other accidents, and stays in hospital in the past thee months.

Many of these correlations were statistically significant.

Mental health

Making links between physical maltreatment and psychological health is an

important step in examining the consequences of child physical maltreatment.

Psychological symptoms that often have been found to correlate with child physical

maltreatment include depression, anxiety, aggression, dissociation, posttraumatic

stress disorders (PTSD), paranoid ideation (Hanks & Stratton, 2002; Lansford et al.,

2002; Malinosky-Rummell & Hansen, 1993)

Quite a few studies have examined the relationship between physical maltreatment

and mental health outcomes among community children and adolescent samples. In a

twelve-year prospective study with data collected annually from 1987 to 1999 among

a community-based sample of 585 children in the US, Lansford et al. (2002) found

that physical maltreatment in the first five years of life significantly predicts

psychological problems (level of aggression, anxiety, depression, dissociation,

PTSD) controlling for the effects of other factors associated with physical

maltreatment. Results of this study provided evidence that effects of early physical

maltreatment may persist over a long period (at least 12 years). A special advantage

of that prospective study is that, the findings are not inflated by retrospective biases

which most studies in child maltreatment area could not overcome.

Further insight into associations between physical maltreatment and mental health

emerged from a survey of nearly 500 secondary school students in Hong Kong (Lau

et al., 2003). Psychological outcomes were measured by Teacher’s Report Form and

the Child Behaviour Checklist (CBCL) completed by parents and teachers

40

(Achenbach CBCL). Lau et al. found that students who reported experiencing two

forms of physical maltreatment (being beaten for no reason by family members in the

last 6 months and ever beaten to injury by family members), had poor mental health.

Correlates between physical maltreatment and anxiety and stress were also reported

in another school-based study in Hong Kong conducted by Lau and colleagues

(1999).

Studies in other countries also showed correlations between physical maltreatment

and several psychological symptoms in school and community adolescent samples. A

lifetime prevalence of Generalized Anxiety Disorder was found to be associated with

experiences of physical abuse among 119 young people (aged 18-21 years) in Japan

(Yamamoto et al., 1999). Similar significant associations (Pearson correlations)

between physical abuse and psychosocial symptoms including depression, anxiety,

dissociation, PTSD, anger, sexual concerns, and somatic problems were reported in a

school-based, cross-cultural study in 4 post-communist bloc countries (Latvia,

Lithuania, Macedonia, and Moldova) (Sebre et al., 2004). The strongest association

found in these countries was between physical abuse and anger, with the highest

correlation in Macedonia [r(275) = .54, p<.001].

Behavioural and academic problems

Physical maltreatment is linked to a wide range of risky behaviours in adolescents

such as self-injurious behaviours, suicidal thoughts and attempts, substance use, and

academic difficulties (Malinosky-Rummell & Hansen, 1993). Lansford et al. (2002)

found in the prospective study mentioned above that adolescents physically

maltreated early in their lives were absent from school more than 1.5 times as many

days, and were significantly less likely to anticipate attending college, compared with

non-maltreated counterparts, controlling for other covariates (socioeconomic status,

family stress, maternal social support, single-parent status, child exposure to

violence, child temperament, and harsh parental treatment during adolescence).

41

Findings from several other studies among population-based adolescent or early

adulthood samples in different countries also support the significant correlations

between CPA and increase in the likelihood of health risk behaviours including

smoking, drinking, other drug use, suicide attempts, involvement in physical fights,

self-mutilation, running away from home, and poor academic achievement (Csoboth,

Birkas, & Purebl, 2003; Fergusson & Lynskey, 1997; Lau et al., 1999; Lau et al.,

2003; Lau et al., 2005; Youssef et al., 1998a). In one of the most comprehensive

studies to date Fergusson and Lynskey (1997) found that among a cohort of 1,025

New Zealand-born children in a 18-year longitudinal study, young people reporting

exposure to childhood physical maltreatment had significantly increased rates of

violent offending, suicide attempts, violent victimization and alcohol abuse, even

after adjusting for various confounding factors (gender, exposure to sexual abuse,

family history of offending, change of parents, exposure to family life events,

maternal age, parental illicit drug use, family income, socioeconomic status,

childhood disadvantages, and family arrangement).

Sexual abuse consequences

Of the published studies with population-based samples of adolescents and young

adults, most measure variables such as depression, anger, anxiety, self-esteem, fear,

and personality disorders. A number of studies examined health risk behaviours,

including substance use, anorexia and bulimia, unsafe sex and teenage pregnancy,

sexual revictimization, and poor school performance (Fergusson & Mullen, 1999;

Hanks & Stratton, 2002; Kenney, Reinholtz, & Angelini, 1997; Krahe, Scheinberger-

Olwig, Waizenhofer, & Kolpin, 1999; Saewyc, Magee, & Pettingell, 2004). There is

a complex pattern of putative effects of sexual abuse, and there are many unresolved

controversies (Haj-Yahia & Tamish, 2001). Some researchers suggest that CSA

almost always leads to short-term and long-term detrimental consequences in

survivors, while others argue that a considerable number of CSA victims do not

report any symptoms at all (Kendall-Tackett, Williams, & Finkelhor, 1993; Rind,

Tromovitch, & Bauserman, 1998).

42

Mental health

Most studies to date have examined correlation between CSA and mental health in

isolation from other concurrent forms of child maltreatment. Overall, the data show

that many CSA victims suffer both acute and chronic psychological problems. The

findings from many studies have been summarised elsewhere (Fergusson & Mullen,

1999). However, it is important in this brief review to focus mainly on studies

conducted outside of North America. A cross-sectional survey was conducted among

a convenience sample of 652 Palestinian undergraduate students (mean age = 20.64

years, SD =2.28 years) to explore correlations of CSA with a wide range of

psychological symptoms (Haj-Yahia & Tamish, 2001). Comparison (t test) of abused

and nonabused participants was examined for nine psychological symptoms:

psychoticism, hostility, anxiety, somatisation, phobic anxiety, paranoid ideation,

depression, obsessive-compulsive, and psychological distress, according to sexual

abuse age (under 12 year olds, 12-16 year olds, and over the age of 16), and

perpetrators (family members, relatives and strangers). The study found that

respondents who were sexually abused by any perpetrators at any age reported

significantly higher levels of all nine psychological symptoms compared with their

nonabused participants.

Similar observation of the relationship between CSA and mental health (depression)

was also found among school-based adolescents in China (Chen et al., 2006; Chen,

Dunne et al., 2004; Chen, Han, & Dunne, 2004). Child sexual maltreatment was

categorized as contact and non-contact abuse experiences that occurred against the

respondents’ will before the age of 16. Depression was significantly higher among

self-reported sexually abused male and female students. However, there was no

significant correlation between CSA and self-esteem, measured by the Rosenberg

scale. Similar findings emerged from a cross-sectional survey of 892 female students

of a medical school in China. Compared to respondents who had no experience of

CSA, sexually abused females (contact and noncontact events) had higher levels of

depression (Chen, Han et al., 2004).

43

Bal et al. (2003) examined correlations between self-reported sexual abuse and

trauma symptoms in nearly a thousand adolescents (aged from 11 to 19 years old)

from a general secondary school, a technical secondary school and vocational

training in Belgium. Trauma symptoms were measured by the Trauma Symptom

Checklist for Children, which includes assessment of: Fear, Depression, Post-

traumatic stress, Dissociation, Anger, and Sexual problems. Multivariate analysis

including gender as a covariate was performed to compared trauma symptom score

between adolescents who reported experiences of sexual abuse and those who

reported different stressful events in her or his life such as exposure to disaster, fire

or explosion, serious accident, being attacked, street fights or war, physical neglect,

abduction, serious disease, death of someone close, witnessing serious injury to

someone, and other events. The authors reported that sexually abused adolescents

significantly reported more fear, depression, post-traumatic stress, dissociation

complaints, anger, and more sexual problems. The research also found that avoidant

coping strategies can be seen as mediator between sexual abuse event and

consequent trauma symptoms.

Adolescent problem behaviours and poor school performance

Quite a few studies have explored the possible effects of childhood sexual

victimization upon various adolescent health risk behaviours. Researchers from

different parts of the world consistently find that adolescents who experienced CSA

were more likely to report smoking, drinking, substance use, suicidal thinking and

attempts, involvement in physical fighting, anti-social behaviours such as stealing

property or causing physical damage to property (Anteghini, Fonseca, Ireland, &

Blum, 2001; Champion et al., 2004; Chen et al., 2006; Chen, Dunne et al., 2004;

King et al., 2004; Martin et al., 2004; Pedersen & Skrondal, 1996; Tomori, Zalar,

Kores Plesnicar, Ziherl, & Stergar, 2001). Various studies indicate that adolescents

who are sexually abused are more likely to begin early consensual sexual activity,

engage in sexual risk taking, or have a teenage pregnancy and revictimization

(Chandy, Blum, & Resnick, 1996; Fergusson, Horwood, & Lynskey, 1997; Kenney

et al., 1997; Krahe et al., 1999; Saewyc et al., 2004).

44

In a large and comprehensive study of 2,946 students in grade 8 and 11 in Cape

Town, South Africa, using ordinal logistic regression, controlling for several

background factors such as race, age, social amenities, family living arrangement,

King et al. (2004) found that students who had ever consumed alcohol were two

times higher than abstainers to report attempted rape or actual rape experience.

Respondents who reported being a victim of sexual violence had significantly

engaged in increasing level of anti-social behaviours in comparison to non-abused

participants (OR = 1.44). Rape and attempted rape were also significant predictors of

suicidal ideation (OR = 2.48) and attempted suicide (OR = 3.20). Stratification by

gender revealed that among girls, alcohol consumption (OR = 2.7), suicide attempts

(OR = 3.13) and anti-social behaviours (OR = 1.47) were significantly related to

sexual abuse. In the contrary, for boys suicidal behaviours were only marginally

significantly correlated with sexual victimization.

Higher rates of early onset of consensual sexual activity, multiple sexual partners,

unsafe sex, teenage pregnancy, sexually transmitted disease, and sexual

revictimization were reported from a long-term study of female adolescents in New

Zealand when various potential confounders had been controlled for (Fergusson et

al., 1997). According to Fergusson, Horwood, and Lynskey (1997) CSA victims had

greater sexual vulnerability during adolescence, perhaps because of many childhood

and family characteristics associated with CSA also were correlated with increased

sexual risk behaviour during adolescence. Fergusson et al. (1997) also suggested that

childhood sexual abuse may encourage victims into early engagement in sexual

activity which, in turn, heightens the sexual risks during adolescence.

Gender differences in the impacts of CSA on various health risk behaviours and

school performance were examined in the Adolescent Health Survey conducted in

Minnesota during the 1986-1987 school year with a sample of more than 36,000

students from grade 7 to 12 in public schools (Chandy et al., 1996). Among 370

males and 2,681 females who self-reported a history of sexual abuse, females were

more likely to engage in internalizing behaviour while males were more likely to

engage in externalizing behaviours. Male adolescents with a sexual abuse history

45

tended to report school performing below average and had higher drop out risk,

delinquency, and sexual risk-taking behaviours compared to abused female

adolescents. In contrast, sexually abused females were more likely to report suicidal

thinking and behaviours, eating disorders and frequent use of alcohol than their male

counterparts. However, males who reported sexual victimization exhibited more

extreme alcohol drinking and more frequent and extreme use of marijuana.

Emotional maltreatment and neglect consequences

In comparison to research into physical and sexual maltreatment, there is a relative

dearth of information on the consequences of emotional maltreatment and neglect

(Hildyard & Wolfe, 2002; Trickett & McBride-Chang, 1995). However, some

experts believe that child emotional maltreatment and neglect is not uncommon and

perhaps has higher prevalence than other forms of maltreatment, and that it has

destructive on health and well-being of the young victims (Crosson-Tower, 2005;

Crosson -Tower, 1999; Egeland, Sroufe, & Erickson, 1983; Glaser, 2002; Hildyard

& Wolfe, 2002; O'Hagan, 1993). Emotional maltreatment may result in a myriad of

long-term impacts. A chronic pattern of maltreatment might destroy a child’s sense

of self and personal safety (Briere & Runtz, 1990). There is also consensus among

child psychiatrists and psychologists that early emotional security is of paramount

importance for later emotional maturity and that even though resilient children and

adolescents may be found to have survived a great degree of emotional deprivation,

the long term consequences of CEA tend to prevail (Corby, 2000; Miller-Perrin &

Perrin, 1999). Neglect, unlike physical maltreatment or sexual abuse which are

usually incident-specific, is often a chronic problem and less obvious so it is more

difficult to identify (Hildyard & Wolfe, 2002). Literature indicates that neglect is

closely linked to emotional maltreatment in that they may lead to similar adverse

consequences (Hanks & Stratton, 2002; Kairys & Johnson, 2002). Some possible

effects of these two forms of maltreatment are:

• Feelings low self-esteem, negative emotional or life view, anxiety, depression,

and suicidal thought and behaviour.

46

• Poor emotional health, including emotional instability, impulse control problems,

anger, self-injury, eating disorders, and substance use.

• Impaired social skills, including antisocial behaviours, attachment problems, low

social competency, low sympathy for others, self-isolation, aggression, and

delinquency.

• Reduced learning ability, including poor school performance and impaired moral

reasoning.

• Poor physical health, including failure to thrive, somatic complaints, poor adult

health.

One study which specifically examined child emotional maltreatment among a

community-based adolescent sample, was conducted in Palestine (Khamis, 2000).

One thousand school children aged from 12-16 years were interviewed at school and

available parents were interviewed at home. Emotional maltreatment was measured

by a 20-item scale consisting of three factors (1: Emotional Abuse - verbal or

emotional assault, close confinement and threatened harm; 2: Emotional Neglect -

inadequate nurturance and affection, child isolation and neglect; 3: Corrupting -

encouraging child maladaptive behaviours such as lying and cheating). After

adjusting for the effects of different variables including child characteristics, parents’

socio-demographics, economic hardship, and family characteristics, emotional

maltreatment was significantly correlated with poor academic performance. In a

cross-cultural comparison of self-report emotional maltreatment among school

students aged 10-14 years old from four post-communist bloc countries, Sebre et al.

(2004) found that emotionally abused respondents in all countries reported

significantly higher psychological symptoms (depression, anger, dissociation, PTSD,

anxiety, sexual concerns and somatic problems) than nonabused participants. The

largest correlation was observed between emotional abuse and anger in four

countries.

Two studies in the United States employed robust design including a case-control

study (Kendall-Tackett & Eckenrode, 1996) and a longitudinal study (Kurtz, Gaudin,

Wodarski, & Howing, 1993). These studies examined the effects of child neglect

47

with school aged samples. Kendall-Tackett & Eckenrode (1996) compared academic

achievement and disciplinary problems between 324 neglected children and

adolescents and 420 matched non-maltreated children and adolescents. Results

revealed that neglected participants had poorer academic performance, had lower

grades, more suspensions, more disciplinary referrals, and more repeated classes

when controlling for gender and socio-demographic status. Kurtz, Gaudin, Wodarski,

and Howing (1993) found that in comparison to the non-maltreated group, neglected

children marginally differed on the measures of socio-emotional development in

school, at home, in the community and with peers after taking into account the

effects of socio-economic status. Notably, neglected students showed severe

academic delays.

Reflections on the broad patterns in evidence linking child maltreatment to health

From the review of the available literature it is evident that the widespread

prevalence of child physical maltreatment, emotional maltreatment, sexual abuse and

neglect as well as the numerous developmental issues and mental health

consequences associated with them has also been recognized (Hanks & Stratton,

2002; Hildyard & Wolfe, 2002; Staudt, 2001; Trickett & McBride-Chang, 1995).

Table 2.3 summarises a number of consequences correlated with each form of child

maltreatment. There is considerable overlap of a wide range of negative outcomes of

individual maltreatment types. However, this literature has been segmented, with

researchers focusing their efforts only on particular forms of maltreatment, which

does not reflect the lived experience of child maltreatment victims.

Children who suffer one type of maltreatment are at risk of other forms of

maltreatment (Clemmons et al., 2003; Higgins & McCabe, 2001b). Studies have

found that different forms of child maltreatment clearly are correlated with each

other and with many background factors such as child and parent characteristics,

socio-economic status, family environment, and community characteristics etc

(Berger, Knutson, Mehm, & Perkins, 1988; Fontes, 2005; Newcomb & Locke, 2001;

Newcomb, Locke, & Goodyear, 2003; Turner, Finkelhor, & Ormrod, 2006). There

are two important implications for research into the effects of child maltreatment.

First, examining effects of only one form of child maltreatment may substantially

underestimate the cumulative impacts of a spectrum of maltreatment exposure on

49

young people. Second, focusing on effects of only one form of child maltreatment

and failure to take into account the effect of various confounding factors and

concurrent maltreatment forms may result in overestimation of the relative impact

upon health of the single maltreatment form that is measured. To fill this gap, studies

have begun to document the effects of the co-occurrence of various forms of

maltreatment and a small body of research has been able to partition the effects of

other maltreatment domains while examining the potential influence of individual

forms of child maltreatment on adverse outcomes (see Appendix 2).

Consequences of co-occurrence of child maltreatment

In recent years there has been growing interest in measuring the consequences of co-

occurrence of various forms of child maltreatment (Ambuel et al., 2003; Clemmons

et al., 2003; Dong et al., 2003; Dube, Felitti, Dong, Giles, & Anda, 2003; Dube et al.,

2006; Hobfoll et al., 2002; Locke & Newcomb, 2004; Newcomb & Locke, 2001;

Walker et al., 1999). Higgins and McCabe (2000a) examined the co-occurrence of

adverse childhood experiences including sexual abuse, physical abuse, emotional

abuse, neglect, and exposure to family violence reported by a community sample of

175 Australian men and women. It was found that 43% of participants reported

experiencing more than one type of maltreatment, while 15.4%, 11.4%, 9.7% and

6.9% of the sample were classified as suffering two, three, four and five types of

maltreatment as a child, respectively. Greater mental health problems significantly

correlated with reports of a larger number of different child maltreatment types.

Moeller, Bachmann and Moeller (1993) reported similar results in their study in the

USA among a sample of 668 middle class females in a gynaecological practice. Half

(53%) of the sample reported childhood abuse (physical, sexual and emotional),

28.9% exposure to one type, 18.7% to two types and 5.4% to three types. This study

also found that the greater the amount of child abuse the poorer one’s health (both

physical and psychological well-being) and the more likely one was to have suffered

abuse as an adult.

50

These early findings have been extended by larger studies. Edwards and colleagues

(2003) conducted a study among 8,667 adult members of a health maintenance

organisation in the USA, to explore the relationship between the combination of

various forms of child maltreatment and adult mental health. Using the mental health

scale of the Medical Outcomes Study 36-item Short-Form Health Survey, the authors

found that lower mean mental health scores were associated with higher numbers of

abuse categories. Both an emotionally abusive environment and the interaction of an

emotionally abusive environment with the various maltreatment types had a

significant effect on mental health scores. A dose-response relationship was found

between the number of forms of maltreatment reported and mental health scores.

Much less research has been conducted to examine the concomitance of different

types of child maltreatment and its impacts among community-based samples of

adolescents in not only developing countries but also in developed nations. Most

studies have considered the combination effects of different forms of maltreatment

focusing only on the combination of two forms at a time and mainly on the

consequences of physical maltreatment and sexual abuse. Additionally, many studies

examined the relative impacts of individual types of child maltreatment have

typically failed to account for possible effects of other forms. Appendix 2 documents

studies on various forms of child abuse and outcomes among adolescents and early

young adults from different parts of the world. This appendix includes a summary of

the form of maltreatment examined, confounding factors controlled, information on

sample size and characteristics, the nature of data collection method, the outcomes

examined, and whether the effects of each type of child maltreatment was

partitioned. In total, 78 studies were summarized, of which 45 studies examined

more than one form of maltreatment with 38 studies exploring the association

between maltreatment and specific health and health risk behaviour outcomes.

However, less than half of the studies (14 out of 38 studies) used multivariate

analysis to partition the effects of each type of child maltreatment. Only 7 studies

examined the concomitance of more than three forms of abuse, and 2 out of 7

reported the cumulative impacts of multiple forms of child victimization. From the

literature review it can be seen that there is no comprehensive study of multiple

51

forms of child maltreatment and its impacts on physical, mental health and health

risk behaviours among adolescent and early young adulthood samples in Asian

countries.

Some research from America among adolescents and young adulthood on the various

consequences of multiple forms of child abuse has also found significant dose-effect

relationships between indices of abuse severity and likelihood of several health

outcomes as well as health-related behaviours (Back et al., 2003; Diaz, Simatov, &

Rickert, 2000; Moran, Vuchinich, & Hall, 2004; Newcomb et al., 2003; Turner et al.,

2006).

Most recently, Turner, Finkelhor and Ormrod (2006) conducted one of the most

comprehensive studies to date among a national representative sample of more than

two thousand US children aged from 2 to 17 years. Telephone interviews were

conducted with the selected child if he/she was 10-17 years old and with an adult

caregiver (usually a parent) if the selected child was 2-9 years old. This sophisticated

study examined a wide range of child life-time victimization and its relative impacts

of each type and cumulative effects of multiple forms of victimization on child

mental health (depression and anger/aggression). Controlling for age, the study

results clearly showed a significant dose-response in comparing mean levels of

depression and anger/aggression across groups with varying levels of victimization

from no victimization to more than four types including physical abuse and neglect,

sexual victimization, witnessing family violence, and other direct and indirect

violence. A hierarchical regression analysis was performed to examine the relative

impacts of each form of victimization on depression and anger/aggression in this

study. After controlling for age, gender, race, socio-economic status, family

arrangement and non-victimization adversity, and other victimization domains, the

study found that every victimization form had its independent effects on the mental

health of victimized children. The findings emphasise that focusing only on recent

adverse experiences and only on one or two forms of child victimization cannot

describe the full picture of the effects on mental health.

52

Through the literature review (Appendix 2), it is clear that there is increasing

evidence regarding significant associations between different types of child

maltreatment as well as their concomitance and health risk behaviours among

adolescents and young people from non-clinical settings. Results of a study

conducted among high school students in the US showed that after controlling for

effects of gender, age and family configuration, all four categories of child

maltreatment (CPA, CSA, CEA and CN) were associated with increased levels of

tobacco, alcohol and illicit drug use. Physical and sexual abuse more than doubled

and tripled the odds respectively of all three substance-use types. Furthermore, the

effect of experiencing the combination of physical and sexual abuse was especially

pronounced (Moran et al., 2004).

In a cohort study of the development of behavioural problems among a thousand US

urban youth who were followed from age 13 to adulthood, Smith, Ireland and

Thornberry (2005) explored the correlations between adolescent maltreatment

experiences and antisocial behaviours including arrest, self-reported general and

violent offending, and illicit drug use at late adolescence (16-18 year olds) and early

adulthood (20-22 year olds). Maltreatment information including sexual abuse,

physical abuse, and emotional abuse and neglect based on substantiated maltreatment

reports. The study found that short-term and long term effects of adolescent

maltreatment varied by the type of maltreatment when controlling for the effects of

parent education, race, caregiver changes, early adolescent offending, and

community poverty. The most consistent pattern was that neglect and emotional

maltreatment significantly increased the odds of arrest (OR = 4.37), general

offending (OR = 3.23), and violent crime (OR = 3.59) in late adolescence in

comparison to non-maltreated participants. Physical maltreatment increased the odds

of violent crime (OR = 2.54) and illicit drug use (OR = 3.66). However, results of

this study revealed adolescents who experienced sexual abuse were not significantly

different from those never maltreated at least in relation to the three antisocial

outcomes examined in late adolescence. On the contrary, antisocial behaviours in

early adulthood were related to sexual abuse during adolescence, especially for

general offending (OR = 5.04) and drug use (OR = 5.07). Neglect significantly

53

increased the risk of arrest (OR = 2.36) and drug use (OR = 2.55) but not general

offending while physical abuse only correlated with violent offending (OR = 2.17) in

early adulthood.

Kendall-Tackett and Eckenrode (1996) examined the effect of child neglect, alone

and in combination with other types of abuse on academic achievement and school

disciplinary problems for elementary, junior high and senior high students.

Recruiting matching samples of abused and non-abused children in a city in New

York State, the study found that the combination of neglect and abuse (physical and

sexual) had particularly strong effect on the number of disciplinary referrals and

grade repetitions, even when controlling for gender of child and SES.

So far only one available study conducted outside the United States examined the

cumulative and relative impacts of four forms of child maltreatment (CPA, CEA,

CSA, CN). A survey of Turkish adolescent students assessed suicide attempts and

self-mutilation (Zoroglu et al., 2003). Logistic regression models supported the

significant contribution of each type of child maltreatment and increases in the

likelihood of suicide attempts and self-mutilation. The study also found significant

relationships between increasing number of maltreatment types and suicide attempts

and self-mutilation. However, this study did not adjust for the effects of possible

related background variables.

From the literature review it is difficult at this stage to interpret the relative effects of

each type of child maltreatment. Some would suggest that emotional abuse and

neglect cause the most damage whereas others point to the strong impact of physical

and sexual abuse. It is not possible to determine the maltreatment-specific impact of

different forms without considering a range of child maltreatment types and wide

range of outcomes and confounding factors. Consistent finding is that co-occurrence

of more than one type of child maltreatment is more traumatic and correlated with

more negative health outcomes than a single form of abuse. This suggests an additive

model of trauma (Fox & Gilbert, 1994). The emphasis of these few studies has

shifted social epidemiological work in the child maltreatment in an important new

54

direction. It seems clear that research in maltreatment field must move beyond the

simple compilation of new survey data gathered from ever more diverse sections of

global population as we know already that child maltreatment is common and

harmful wherever it has been measured. The new findings about the cumulative

impacts of multiple forms of child maltreatment are important but at present limited

to Western, affluent, English speaking populations, except the small study in Turkish

adolescents. There is a need to understand the generalisability of these findings.

2.5 Child maltreatment in Vietnam

Introduction

Children have always held a very important place in the culture and traditions of

Vietnam (Appendix 3 summarizes the country’s profile). In 1989 Vietnam was the

first country in Asia and the second in the world to ratify the UN Convention on the

Rights of the Child (Salazar-Volkman, 2004). The Vietnamese government’s second

National Programme on Action for Children 2001- 2010 sets forth clear policy goals

in the areas of health, nutrition, education, child protection, water, sanitation, culture

and recreation (UNICEF, 1999).

At present, Vietnam does not have a specific body of legislation concerning child

maltreatment. There are, however, many laws that have been introduced with

components aimed at protecting children from harm and exploitation. More than 110

laws and regulations relevant to children were issued by the National Assembly, the

Prime Minister and Government bodies during the period from 1998 to 2002 alone.

These legal documents mainly focused on promoting education for children,

strengthening services for children, and improving protection from violence through

more stringent punishment of perpetrators (Salazar-Volkman, 2004). The Law on the

Protection, Care and Education of Children passed in 1991, which was revised in

2004, was the most important document in the aftermath of the UN Convention on

the Rights of the Child. In the revised law one chapter relating to disadvantaged

children was added, however other important dimensions regarding child

55

maltreatment were not covered except for extremely severe cases such as child rape,

child prostitution, or severe injuries and death (PFCSI & SCS, 2005). On the one

hand, many laws and regulations relevant to children were issued as an indicator of

increasing awareness of the Government on the importance of child protection. On

the other hand, this does not mean that child protection in Vietnam has significantly

improved, because of obstacles in implementation and enforcement of these many

legal documents. Many challenges remain for the Vietnam Government during this

period of social and economic transition before the rights set forth in the UN

Convention on the Rights of the Child can be exercised and enjoyed by all

Vietnamese children.

Research on child maltreatment in Vietnam

There is a serious dearth of research on the exposure of children in Vietnam to

maltreatment, especially research on the general population. As a consequence, it is

impossible to obtain accurate figures on the extent of child maltreatment problems in

this country. Numerous factors may explain the paucity of research and inability to

obtain precise figures. These include under-recognition of the issues by stakeholders,

a traditional reluctance to discuss issues related to child abuse (especially sexual

abuse), reluctance to intervene in family lives of others, and no mandated reporting

system. Further, there may also be influential perceptions that other health and social

problems demand more urgent attention. However, it is widely believed that the

actual rate of child abuse is rising (MOLISA, 1999) and this increase exceeds the rise

in cases documented in official government statistics reported by police and court

(child abuse cases recorded by police and courts are only child rape or sexual

exploitation) (SIDA, 2000). Available data show that before 1990, child rape

accounted for only 6% of all rape cases. By 1996, this figure has increased to 30%.

In the first 6 months of 1999, the number of child rape cases increased by 25%

compared to that number for the same period of 1998 (Hoang, 1998; RaFH, 2002).

No paper specifically relating to child maltreatment in Vietnam has ever been

published in international academic journals. Most of the research carried out so far

in Vietnam in this field has employed qualitative methods and mainly focused on

56

CSA, including child prostitution and child sexual exploitation among convenience

samples of disadvantaged children such as street children, child prostitutes and

children in rehabilitation centres or government shelters (Le, 2002; MOLISA, 1999;

Ngo & Flamm, 1997; Nguyen, Phan, & Duong, 1997).

There have been several quantitative community-based studies conducted among

children that include some data related to child physical maltreatment. In a survey

carried out by Hoang and colleagues (2001) the researchers explored the kinds of

methods parents use to educate their children. They interviewed a sample comprising

50 girls, 50 boys (from 4 to 18 years old) and their parents. Results showed that

parents often used physical punishment as a method to “educate” their children, and

the following methods were used: slapping or knocking on the child’s head (26.0%),

hitting on the buttocks (22.0%), beating with a rod (21.8%), slapping on the thigh

(20.1%), slapping on the buttocks (19.8%), pinching (19.6%), beating the child with

uncontrolled anger (19.5%), shaking the child (15.0%), rushing and hitting the child

(11.7%) and kicking the child (5.3%). However, the researchers did not ask the

parents about the frequency of acts and if they considered any of the above acts to be

physically abusive to children. A large-scale survey among a randomly selected

sample of 2400 adolescents (aged from 13-22) conducted in 7 provinces representing

7 ecological and socio-economic regions in the country revealed little information

relevant to child maltreatment. Regarding corporal punishment there were 26% of

boys and 20% of girls who reported being physically punished by their teachers. This

was more common in the rural than urban areas (25% and 18% respectively)

(Mensch, Dang, & Clark, 2000).

A survey of 1240 Vietnamese children undertaken by the Youth Research Institute in

1998 showed an alarming figure on the situation of physical punishment against

children (Le, 1999). About 90% of children reported being regularly beaten by their

parents with about 50% claiming that the reasons were unjust. Children who reported

being severely beaten accounted for 65%. Roughly 70% of regularly beaten children

said that they felt very sad about being hit by their parents and about 28% said that

they were very angry with their parents. This figure on physical punishment seems to

be quite high. However, physical punishment in this study was defined generally in

57

terms of beating children and may not includes other acts commonly considered to

constitute physical maltreatment. Therefore it may not provide a valid estimate of the

extent to which Vietnamese children are exposed to severe physical maltreatment.

Very recently, the Population, Family and Children Scientific Institute-National

Committee on Population, Family and Children in collaboration with Save the

Children, Sweden, have conducted a survey on corporal and emotional punishment.

The participants included 571 parents or adults in families, teachers, child protection

staff and 514 children mainly aged 6-18 years old in four provinces in the North,

Centre, Centre Highlands, and the South of Vietnam (PFCSI & SCS, 2005). The

study employed a multi-method approach, including a quantitative survey with

parents and children, in-depth interviews with child protection staff, children and

adults, focus group discussions with teachers, and feedback letters from children

aged 11-18 years. This study revealed important and interesting information to set a

baseline for the Save the Children Alliance in Vietnam to launch a campaign against

corporal punishment in 2005.

When asking parents and adults “what did they do if a child made a mistake?” a

significant proportion (37.3%) reported shouting at a child, nearly one third (28.6%)

reported using corporal punishment, and one fifth (20.2%) said insulting a child or

trying to make a child feel guilty as the “methods” employed. They also reported

hitting with a rod and hand to the bottom of children is the only ways they have done

when conducting corporal punishment to “educate” children. Yet the information

revealed by children in this survey was somewhat different with more than half

saying they have been beater, kicked, tied or locked in house. Adolescents reported

more emotional punishment such as being threatened to be sent out of their home,

which made them very disappointed in their parents. Table 2.4 summarises the

experiences of corporal punishment reported by children in this study. Whether

parents and adults under reported what they actually practiced or whether children

over reported their experiences is unknown. However, parents and adults had

reported that they knew neighbours punished children in such a way that caused blue

marks, welts, injuries, and forced children to run away from home.

58

Most children in this study (69.3%) reported that they felt sad when being physically

or emotionally punished by adults mainly due to their mistake, but also because their

parents and adults did not listen and understand them and sometimes punished them

without any reason. More than sixty per cent of children said that they felt ashamed,

less confident, and frightened because of parent and adult punishment. Especially, a

small group of children felt very angry and wanted to take revenge. Approximately

fifty per cent of children participants completely disagreed with the current used

physical and emotional punishment by parents and adults.

Adapted from PFCSI & SCS (2005)

In 2003, the most substantial community-based research on child maltreatment topic

in Vietnam was conducted by Michaelson (2004), a UNICEF Vietnam consultant.

The study was a comprehensive investigation into the concept, nature and extent of

all forms of child abuse in Vietnam, including sexual abuse, emotional and physical

maltreatment, and neglect, the impact of domestic violence on children, commercial

sexual exploitation of children, trafficking of children, and child labour. The research

was undertaken in Hanoi (capital), Angiang (in the South), and Laocai (mountainous

province in the North) among 2,800 participants (aged from 8-35 years old) for a

quantitative survey, and 178 children and young people (aged 8-25 years old) and

59

134 adults (aged 27-63 year olds) for a qualitative study. The participants represented

a diversity of backgrounds, including children and young people from primary,

secondary and high schools, universities, reform school and social protection centres,

and children on the street, adults working as teachers, consultant/street educators,

social protection centre staff, government representatives, academics, non-

government organisation staff, private sector representative and community parents.

Even though the information presented in this study’s report was basically

descriptive, it provided a base of preliminary evidence relating to concepts, nature

and extent of various forms of child abuse from a diversity of respondents. There are

five important findings of the study.

First, violence is not an unfamiliar experience of children and young people growing

up in Vietnam. The vast majority of respondents reported having experienced some

form of physical punishment (70% experienced spanking with a hand; 51.5%

reported physically punishment with an implement; 16.2% experienced physical

attack from adults). More than one third of the participants (35.7%) reported having

experienced emotional abuse. Nearly eight per cent (7.9%) of respondents

experienced unsafe touching of private parts and 2.7% reported having been raped or

experiencing another form of sexual assault as a child. Surprisingly, males were

twice as likely as females to report having a sexual abuse experience. Physical

bullying by other children was also very common (71.5%) and about one in three

participants (29.3%) reported having witnessed physical violence between adults in

their family. Traditional forms of neglect i.e. failure to take care a child’s basic needs

had been reported by respondents in the qualitative study. Parental deprivation of a

child’s right to education and emotional neglect of children by parents who spend a

lot of time at work emerged as a common form of neglect mentioned by participants.

Second, older participants were less likely to view “physical punishment for

education” as child abuse, while the majority of the younger generation believed that

it is abusive, on the ground that there are better and more humane ways of educating

children. Third, the cultural practice of adult male relatives fondling penises of

young boys was raised as an experience disliked by many young males. Fourth,

60

“education pressure” is a relatively new phenomenon but emerged as problem facing

youth. This issue was most commonly reported by young people from urban rather

than rural areas. Fifth, the research results demonstrated a high awareness among

participants in relation to child prostitution and trafficking and child sex tourism but

much less to child pornography and internet related child abuse.

So far there is no single quantitative study exploring the issues of emotional, physical

maltreatment, sexual abuse and neglect as well as examining the relative effects of

each form of child maltreatment and cumulative impacts of co-occurrence of various

forms of child maltreatment on health related behaviours, mental and physical health

problems in Vietnam. There is a need therefore for specific research investigating the

prevalence and effects of all forms of child maltreatment in order to provide relevant

evidence for Vietnamese public health solutions.

To sum up, through limited research evidence, media reports and observations it is

widely believed that child maltreatment in Vietnam is as serious a social and public

health issue as in other countries. During the past several years a great deal of

attention has been given to the topic of child maltreatment in the media in Vietnam.

However, there is still a lack of community-based research evidence to provide a

more comprehensive understanding of the concepts of various forms of child

maltreatment, the extent to which the problem exists, and its potential effects on the

health and well-being of victimised children. Without scientifically sound research it

is impossible to set firm foundations for future prevention, intervention and treatment

strategies. The main purpose of the present study therefore was to meet, to some

extent, this compelling need, so that we may contribute to collective and long-term

endeavours to combat child maltreatment in Vietnam.

After reviewing a relatively substantial body of international research and the little

available evidence on child maltreatment in Vietnam, the gaps in child maltreatment

literature have been identified. As a result, the following hypotheses of this study

were proposed:

61

1. The prevalence of physical maltreatment, emotional maltreatment, sexual abuse

and neglect is different between school boys and girls.

2. The prevalence of physical maltreatment, emotional maltreatment, sexual abuse,

and neglect among school adolescents is different between urban and rural

districts.

3. Physical maltreatment, emotional maltreatment, sexual abuse, and neglect

experiences independently increase risk of engaging in various health risk

behaviours of adolescents.

4. Each form of child maltreatment independently increases the risk of having

depression, anxiety, and physical health problems, and decreasing self-esteem of

adolescents.

5. There are dose-response relationships between increasing number of types of

child maltreatment experiences and the likelihood of taking health risk

behaviours, and poor health among adolescents.

62

Chapter 3: Research Methods and Pilot Study

3.1 Methodological considerations in research on child maltreatment

Studying child maltreatment in the general population is difficult due to factors such

as the sensitivity of the topic, the related legal, ethical, and practical restrictions and

the difficulty in determining the reliability and validity of retrospective data (Kinard,

1994). Although child maltreatment research has become more methodologically

sophisticated over time, it has often been subjected to criticism for methodological

deficiencies. Many questions have been raised about the validity, comparability, and

generalisability of findings regarding prevalence and consequences of child

victimization. The main methodological issues that need to be taken into

consideration include: definitions of child maltreatment; source of study population

and method of sampling; and potential bias associated with measurement (Creighton,

2002; Edwards et al., 2001; Hecht & Hansen, 2001).

Definition of child maltreatment

As discussed earlier, there is the lack of a clear, generalizable definition of child

maltreatment. Research definitions of child maltreatment within a certain culture

cannot be drawn without carefully considering the nature of the parent-child

relationship and the nature of other relationships affecting the child in his/her social

context (Haj-Yahia & Shor, 1995). Specifically, Crosson-Tower (1999) argued that

there are cultural dissimilarities in attitudes regarding what are acceptable or

unacceptable practices towards children.

Definitions are promulgated for multiple purposes and may vary between different

legal, social service, clinical, and scientific contexts. Definitions created for clinical

63

purposes might not be easy applied in research based on the general community.

There have been various questions that should be raised before deciding on the

operational definition for the study. For example, what constitutes dangerous or

unacceptable practice towards children? What should be included in classification

systems about maltreatment subtypes, severity, frequency, and consequences?

Should the definition be based on adult behaviours or subjective outcomes for the

child? Should the presumed intent of the perpetrator be included in definitions?

Which aspect of the context of the maltreatment should be included and how?

(Dubowitz et al., 2005; Socolar, Runyan, & Amaya-Jackson, 1995). There are no

clear answers to these questions. However, it is suggested that operational definitions

of child maltreatment must be as concrete and specific as possible using simple,

behaviourally specific language (Hamby & Finkelhor, 2000). Operational definitions

must also take into account cultural appropriation to select adequate samples and

facilitate comparisons across studies.

Keeping these principles in mind, in this project, child maltreatment was categorised

into four types measured by four scales including a continuum of behaviours towards

children. Operational definitions of each type of child maltreatment and measuring

scales are presented in detail later in this chapter. The development of definitions and

scales was based on the following steps:

• Identifying the different definitions used by researchers through literature search

internationally and locally. The focus was on defining maltreatment in terms that

are behaviourally specific, culturally acceptable, appropriate for the age of

research participants, and to some extent comparable with other research.

• In-depth discussion with experts

• Testing qualitatively and quantitatively with potential study participants in a pilot

study.

64

Sources of research population and sampling method

It appears that child maltreatment prevalence rates and the extent to which child

mistreatment correlates with health status are affected by variation in research

samples (Goldman & Padayachi, 2000). Studies in this field often select convenience

samples from clinics or hospital patients, or from the criminal justice system,

shelters, and special intervention services. These sources of research population often

include more severe abuse cases. Data obtained from these populations, as Pope and

Hudson (1995) indicated, are vulnerable to biases, including information bias, which

is a major threat to internal validity of findings.

Over time the number of published articles on child maltreatment using college and

outpatient samples has increased (Behl et al., 2003). Yet, Ryan and colleagues (2000)

questioned the representativeness of college samples regarding the assessment of the

impact of child maltreatment on adjustment problems. They argue that college

students have better coping skills, so this could diminish differences between the two

groups of maltreated and non-maltreated students in adjustment problems.

However, as far as maltreatment prevalence is concerned, Dunne (2002) in his

review of 13 studies on CSA experiences of females included 7 general population-

based and 6 student-based samples. He found considerable similarity in terms of

average child sexual maltreatment prevalence rates. He suggested that samples

selected from different segments of population do not always result in significant

differences in prevalence rates. Gorey and Leslie (1997) also found that the sources

of the research populations (general sample or college sample) and sampling

methods (probability or convenience sample) did not significantly explain the

prevalence variation in their review of 16 CSA cross-sectional studies among a non-

clinical population in North America whereas response rate and abuse definition

explained half of the variability of abuse prevalence estimates.

65

Measurement bias

Measurement of variables related to child maltreatment, either as an outcome or a

risk factor, is problematic. Retrospective survey data are subjected to recall bias,

particularly in studies in which the abusive events may have occurred many years

before. Because of the sensitive nature of this topic, disclosure problems also

jeopardise measurement (Socolar et al., 1995). The method of collecting data is also

another important issue, but there is little evidence available on the effects of

assessment mode on reporting maltreatment experiences. Different suggestions have

been provided by research groups. Interview methods did not significantly explain

much variance in CSA prevalence estimates in Gorey and Leslie’s (1997) integrative

review of 16 surveys. However, Socolar and colleagues (1995) suggested that self-

administered surveys are more likely to be accurate. Self-administration

questionnaires are often used to collect data in school settings and in group

administrations. In contrast, Goldman and Padayachi (2000) indicated that face-to-

face interviews are likely to produce more accurate data by trained interviewers who

have the capacity to encourage respondents to uncover their personal matters. These

researchers also demonstrated how the content and structure of questions on child

maltreatment in any method of data collection result in inconsistencies in research

findings. They concluded that fairly low rates of child maltreatment were revealed by

those studies using only limited screening questions. Among 20 recommendations

for assessment and instrument development used in a child victimization study,

Hamby & Finkelhor (2000) suggested that it is possible to collect self-report data

with children as young as 7 years old, but to date there is no conclusive evidence

available supporting a major advantage of any one data collection method.

Research on child maltreatment must be not only methodologically rigorous, but also

practically feasible. When trying to obtain accurate findings for child maltreatment,

researchers have encountered various practical problems in implementing even well-

designed studies that make it difficult to conduct research in this area. A research

design that appears both ethically and scientifically sound would involve longitudinal

study of a large and representative sample of children followed up at regularly

66

scheduled intervals from childhood to adulthood. By this design some major

methodological pitfalls mentioned above could be avoided. Unfortunately, this

design is not feasible to implement in many contexts and to date few studies have

been able to use this approach such as a study in New Zealand (Fergusson et al.,

1997; Fergusson & Lynskey, 1997) and LONGSCAN (LONGitudinal Studies of

Child Abuse and Neglect) in the US (Runyan et al., 1998). It is important that

investigators be aware of potential constraints and equip themselves with various

mechanisms to minimise these barriers.

3.2 Design of this study

A mixed methods design (Creswell, Clark, Gutmann, & Hanson, 2003), including

qualitative and quantitative methods was employed. Creswell and colleagues (2003)

argue that mixed methods designs allow researchers to develop a more

comprehensive understanding of the complexity of human behaviours and

experiences. The incorporation of the qualitative method in the present study adds an

important cultural dimension on child maltreatment problems, in turn helping to

develop appropriate quantitative measures. The mixed methods design applied in this

study is depicted in Figure 3.1 and is discussed in more detail later in the chapter.

Stages of study: The study was conducted in Vietnam in three stages as

follows:

Stage 1: Qualitative in-depth interviews and focus group discussions

Qualitative research based on ethnographic methods attempts to interpret and present

findings from a cultural perspective. As discussed in the literature review, child

maltreatment is a complex, multifaceted, multi-determined and, to some extent,

culturally-specific issue. Haj-Yahia and Shor (1995) argue that we should take into

account the social and cultural components, to ensure a comprehensive approach to

this sensitive topic. Qualitative methods were employed in stage 1 as a useful

67

exploratory tool providing insight into how people perceive child maltreatment and

make sense of their experience in a way that could not be easily provided by other

methods (Grbich, 1999; Rice & Ezzy, 1999). Stage 1 of the present study included

two steps:

Step 1: In-depth interviews with teachers, parents and students themselves.

The aims of this step were to:

• explore how teachers, parents and students perceive child maltreatment as a

concept;

• discover the nature of the child maltreatment phenomenon through interviewees’

experiences; and

• examine how to use culturally appropriate terminologies/words in research

questionnaires for this study population, especially when investigating child

sexual abuse.

Interviews were completed with 16 participants, including 4 teachers, 4 parents and 8

students (see guideline for in-depth interview in appendix 5).

Step 2: Focus group discussions (FGD): Eight FGDs, 6-8 students for each FGD,

were conducted in urban and rural study sites (4 FGD for each site) and with students

from both lower and upper secondary schools. Given the sensitivity of the topic,

gender homogeneity of each FGD was taken into account (4 girl FGDs and 4 boy

FGDs) (see guideline for focus group discussion in appendix 6).

The purposes of this step were to:

• inform researchers about young people’s familiarity with the child maltreatment

problem;

• have feedback from students on structure, content and wording of study

instruments in order to revise them (students completed the self-administered

questionnaire individually then discussed their general comments in the group);

and

• gain suggestions from participants about questions that could be included.

One class of each grade 7, 9 and 11 was recruited from 1 lower secondary school and

1 upper secondary school for each study site (2 lower secondary schools, 2 upper

secondary schools with 6 classes in total for 2 study sites – Dongda urban district and

Chilinh rural district). The main findings of the pilot study will be presented later in

this chapter.

The aims of this stage were threefold, to:

• check that the management procedures for survey implementation were

appropriate and successful;

• re-examine the strengths and weakness of the questionnaires and to amend them

where necessary; and

• get preliminary prevalence data on various types of child maltreatment that could

be used to calculate the sample size for the stage 3 survey.

Stage 3: Conduct main survey to test study’s hypotheses

3.3 Study participants

The school-based population comprised students from Vietnamese public lower

secondary schools (grade 7 to grade 9, age generally ranges from 13-15 years) and

upper secondary schools (grade 10 and grade 11 aged 16 and 17 years). Four

teachers, 4 parents and 64 students were recruited for qualitative interviews and

focus group discussion. In total there were 326 and 2,737 students invited to

participate in the pilot and the main study respectively.

70

3.4 Study sites

The study was conducted in two districts in the North of Vietnam selected (see map

in Appendix 4). One urban area and one rural area were purposively selected.

Urban area: The urban area selected was Dongda district, Hanoi capital city,

with 5 public upper secondary schools and 17 public lower secondary schools.

Dongda was chosen because it is one of the nine districts of Hanoi city. It has an

estimated population of 336,000 people in comparison to three other inner districts,

Hoankiem, Badinh and HaiBaTrung with smaller populations of 159,761; 191,611

and 347,400 respectively, according to the 1999 census. Dongda is a typical

municipal district including many common living quarters. It has average socio-

economic development and investment (Vu, 2000).

Rural area: The rural area selected was Chilinh district, Haiduong province. This

district is approximately 60 kilometres Northeast of Hanoi with two public upper

secondary schools and 20 public lower secondary schools. Chilinh was selected

because it is the field-lab of the Hanoi School of Public Health namely CHILILAB–a

Demographic Epidemiologic Surveillance System with establish management

procedures and locally capacity to use trained research assistants as data collectors

for this project. CHILILAB is a member of INDEPTH, an International of field sites

with continuous Demographic Evaluation of Population and Their Health in

developing countries, network. It has a focus on studying adolescent health. Chilinh

is located in both the Plains (35%) and Midlands (65%) areas of Vietnam. Socio-

economic development and urbanisation processes are similar to that of Haiduong

province (Chilinh People's Committee, 2003).

3.5 Timeline

This study was conducted through 2004 and 2005:

• the qualitative study took place between January and March 2004;

71

• the pilot study (n = 299) was conducted in May and June 2004; and

• the major survey (n = 2591) was undertaken between December 2004 and May

2005.

3.6 Instrument development In this study the following definitions of 4 forms of child maltreatment were used.

These definitions were developed based on reviewing literature and the results of

qualitative study.

Definition of child maltreatment of the study: Child maltreatment is

any forms of sexual, physical and emotional abuse and neglect. In this study,

different forms of child maltreatment were conceptualized as a continuum of

behaviours toward a child aged less than18 year olds.

Physical abuse: Frequency of violence of any adult (in a family and outside a

family) toward a child (under 18 years old) including spanking, pushing, grabbing,

shoving, locking, tying or chaining, kicking or hitting, beating up.

Sexual abuse: Frequency of sexual behaviours between any adult family member

or non-family member and a minor (under 18 years old) against child’s will

including talking in a sexual way, exposing adult’s private part to a child, forcing a

child see sexual scene, touch or fondle adult’s private parts, touching or fondling

child’s private parts, attempted intercourse or intercourse.

Emotional abuse: Frequency of verbal or psychological threats of any adult in

family toward a child (under 18 years) including yelling, insulting, making a child

feel guilty, embarrassing and humiliating a child.

Neglect: Failure of parents or caretakers to provide for a child’s physically and

emotionally fundamental needs including adequate food, clothes, care when child’s

sick, close and sources of strength to a child.

72

Instrument development process Three instruments were developed for use in this study: a guideline for in-depth

interviews (see Appendix 5); a guideline for focus group discussion (see Appendix

6); and a self-administered questionnaire for the quantitative survey (see Appendix

7). The following steps were applied to develop and finalise the questionnaire as the

key instrument for this research:

• Examination of previous literature;

• Discussions with experts;

• Compilation of draft questionnaire;

• In-depth interview with children, parents and teachers;

• Focus group discussion with children to record their comments on a preliminary

questionnaire;

• Questionnaire modification in response to comments made during the focus

groups and results of the in-depth interviews;

• Pilot survey in both urban and rural districts; and

• Questionnaire finalisation based on results from pilot survey data analysis.

The questionnaire was originally developed in English and then translated into

Vietnamese by two bilingual Vietnamese public health professionals. Back-

translation was then undertaken by another bilingual Vietnamese person with post

graduate qualifications in social science. The back-translation version was reviewed

by an English native speaking expert to confirm its equivalence with the original.

The same version of the questionnaire was administered to juniors in lower

secondary schools (grades 7, 8 and 9) and the senior cohort in upper secondary

schools (grades 10 and 11).

73

Main contents of the questionnaire The questionnaire for the pilot study consists of the following sections:

• Demographics

• Family environment

• School and work

• Childhood experiences: It includes 4 scales measuring four forms of child

maltreatment (physical, emotional maltreatment sexual abuse, and neglect), and 4

scales measuring physical health problem and mental health (depression, anxiety,

self-esteem). This section also consists of 11 items measuring health risk

behaviours.

Child maltreatment scales:

In the childhood experiences section, questions measuring four forms of child

maltreatment were developed. Mostly, these were modified from various sets of

questionnaires previously used internationally and demonstrated to have good

internal consistency (α coefficient) including: the Revised Conflict Tactics Scale

(Straus, Boney-McCoy, & Sugarman, 1996); the Juvenile Victimization

Questionnaires (JVQ) (Hamby & Finkelhor, 2001); and the Childhood Trauma

Questionnaire (Bernstein et al., 2003). As well, several other scales developed and

used in countries such as Australia (Higgins & McCabe, 2001a), South Africa (Madu

& Peltzer, 1999) and China (Chen, Dunne et al., 2004) were used. In constructing the

items, words reflecting abstract categories or value judgements (e.g., abuse,

perpetrator, victim) were avoided in favour of descriptions that were behaviourally

specific such as “kicking”, “yelling at you”, and “exposing their private parts”. These

4 maltreatment scales were:

• Emotional maltreatment included seven items using a 5-point scale ranging from

never, rarely, sometimes, often, and always.

• Neglect included seven items using a 5-point scale ranging from never, rarely,

sometimes, often, and always.

74

• Physical maltreatment included four items using a 5-point scale ranging from

never, rarely, sometimes, often, and always.

• Sexual abuse consisted of nine items using a 3-point scale (never, once, more

than once).

Physical health problem scale: Self-reported physical health problem scale was

developed including eight items asking about various physical illnesses using a 3-

point scale (never, sometimes, often).

Mental health scales: Self-reported mental health problems included anxiety,

depression, and self-esteem scales.

• Anxiety scale: To the best of my knowledge, no validated or locally

developed anxiety scale is currently available to use for screening in population

based adolescent samples in Vietnam. A review of recent literature reveals that

some published anxiety measures have been validated with normal adolescent

samples in Western countries and show satisfactory psychometric quality.

The State-Trait Anxiety Inventory (STAI) was validated in the United States

among Asian/Pacific Islander in Hawaii and in Belgium (Hishinuma et al., 2001;

Muris, Merckelbach, Ollendick, King, & Bogie, 2002). Muris et al. (2002), in the

same study also tested the quality of five other anxiety scales including the

Revised children’s Manifest Anxiety Scale (RCMAS), the Fear Survey Schedule

for Children - Revised (FSSC-R), the Multidimensional Anxiety Scale for

Children (MASC), the Screen for Child Anxiety Related Emotional Disorders

(SCARED), and the Spence Children’s Anxiety Scale (SCAS) in a large sample

of school adolescents. Psychometric properties of SCAS, MASC, the Social

Anxiety Scale for Adolescents (SAS-A), the Social Phobia and Anxiety

Inventory for Children (SPAI-C), and the Anxiety Sensitivity Index for Children

(ASIC) have also been evaluated in Australia and the United States (March,

Sullivan, & Parker, 1999; Myers, Stein, & Aarons, 2002; Spence, Barrett, &

Turner, 2003; Storch, Masia-Warner, Dent, Roberti, & Fisher, 2004; Valentiner,

75

Gutierrez, & Blacker, 2002). Generally, these anxiety scales consist of between

20 to 80 items except for SAS-A, and ASIC. Even though we understand that

choosing instruments used internationally will enable systematic comparison

with available data from other countries, after thoroughly reviewing these

validated anxiety measures, no instrument was selected for several reasons. First,

in the context of our project the participants have to answer numerous other

questions in a 35-minute timeframe. It is therefore necessary that the anxiety

measure should be short and succinct. The ASIC, which is brief, was considered

for use in the present study. However, as Stallings and March (1995) suggested in

their comprehensive review of childhood anxiety measures, instruments should

provide reliable and valid ascertainment of symptoms across multiple symptom

domains. With this in mind, although the ASIC consists of 12 items, it is not the

option of choice as it measures only the anxiety sensitivity construct which is

insufficient for the purpose of this study. Second, when using an instrument

originally developed in another language in a new cultural group, it is crucial to

ensure cultural congruence of a construct. The original instruments must use

language and wording in a way that makes sense when translated to the new

study population. None of the brief anxiety scales could completely be translated

into Vietnamese with equivalent meaning.

In the light of these decisions and based on the reviewed literature on anxiety

measures, a short anxiety scale including items measuring various anxiety

symptoms such as separation anxiety, generalized anxiety, social anxiety,

perfectionism, and physical symptoms was developed (Muris et al., 2002; Myers

et al., 2002). This anxiety scale was originally drafted with 16 items using a 3-

point scale (never, sometimes, often). After consulting two bilingual Vietnamese

experts, it was shortened to 14 items. This scale was tested in the pilot study to

determine its quality before using to screen anxiety symptoms in the main survey

of school-based adolescents. Results of exploratory factor analysis and reliability

in terms of internal consistency of this scale are presented in the pilot study

section of this chapter.

76

• Depression scale: The Centre for Epidemiological Studies-Depression Scale

(CES-D) (Radloff, 1977) has been shown to be a reliable measure for assessing

depressive symptoms across race, gender, and age categories. High internal

consistency has been reported with Cronbach’s alpha coefficient ranging from

0.85 to 0.90 in the general population samples tested (Radloff, 1977). The 20-

items have a 4-point scale for most or all of the time to rarely or none of the time

reported for the previous week. It was designed to measure depression symptoms

in community surveys, and has been used extensively with adolescents (Chen,

Dunne et al., 2004; Lam et al., 2004; Radloff, 1991). Cumulative scores can

range from 0 to 60; the higher the score, the higher the depression. The standard

cut-off point of the CES-D for community sample is sixteen (Turk & Okifuji,

1994).

• Self-esteem scale: The Rosenberg self-esteem scale (RSES) (Rosenberg,

1965) has been used. This scale is a 10-item questionnaire that was originally

developed to measure adolescents’ global feelings of self-worth or self-regard.

Five of the 10 items are worded in the positive and the other five items are

worded in the negative. The RSES is commonly administered using a 4-point

response format ranging from strongly agree to strongly disagree. A cumulative

score can range from 0 to 30 (higher scores indicate higher self-esteem). The

scale generally has favourable reliability, test-retest correlations are typically in

the range of 0.82 to 0.85 after a 1-week interval or a 2-week interval respectively,

and Cronbach’s alpha coefficient for various samples are in the range of 0.77 to

0.88 (Miyamoto et al., 2000).

Health risk behaviour measure: Health risk behaviours are actions people

take that can be harmful to their health and well-being such as substance use and

drug abuse, binge drinking, fighting, and suicide (Zweig, Lindberg, & McGinley,

2001). In this study, eleven items measuring health risk behaviours have been

adapted from the Questionnaire of Youth Risk Behaviour Survey (YRBS) developed

by the Centres for Disease Control and Prevention in the United States in 1990. The

questionnaire originally included approximately 88 items and has demonstrated good

77

reliability (Brener, Collins, Kann, Warren, & Williams, 1995; Grunbaum, Lowry,

Kann, & Pateman, 2000). Eleven adapted items refer to severe sadness or

hopelessness, suicidal attempt, suicide planning, cigarette smoking, alcohol drinking,

eating disorders and violence-related behaviours using Yes/No response options.

YRBS had been widely used in various studies among adolescents in Asian countries

such as China (Chen, Dunne et al., 2004) and Thailand (Ruangkanchanasetr,

Plitponkarnpim, Hetrakul, & Kongsakon, 2005).

3.7 Sample selection

A two-stage cluster sampling technique was employed. The sampling procedure is

depicted in the following chart (see Figure 3.2). Districts were purposely selected.

Schools within districts were randomly selected. Then classes within schools were

randomly chosen. All students in randomly selected classes were invited to

participate in this study.

3.8 Data collection

The questionnaires were self-administered in school classrooms in single sessions

during regular school hours in the pilot study and the main survey. At the time of the

survey, the study purposes were explained to students. They were told that

participation was voluntary, their responses would be anonymous, there were no

right or wrong answers, and they could stop or withdraw from participation at any

time. To protect confidentiality and to ensure standard administration procedures,

anonymous questionnaires were administered by trained researchers without the

presence of class teachers. Students were asked to focus on their own responses

without any discussion. Study participants put completed questionnaires in sealed

envelopes. The field manual for collecting data was developed to provide practical

information necessary to ensure that standard methods were used to collect data in all

participating sites.

3.9 Data management

Qualitative data

All in-depth interviews (16 interviews) and focus group discussions (8 FGDs with an

average of 6-8 students for each FGD) were audio taped and trained researchers also

took manual notes. All audio taped interviews and FGDs were transcribed into

Vietnamese.

Quantitative data In order to ensure data integrity, the following steps were taken:

• A coding manual was developed for the pilot survey and modified for use in the

major survey.

• Two experienced researchers cleaned all the returned questionnaires for

inconsistent responses and non-responses before conducting data entry.

79

• It was ensured there were no double-ups in ID numbers and all ID numbers were

in range. The IDs for the pilot survey ranged from 1 to 299 and for the major

survey ranged from 1 to 2591.

• Data was entered into Microsoft Access database by two experienced research

assistants. Double entry verification was used on a random sample of 10% of the

returned survey questionnaires.

• Frequency distributions of all variables were generated and checked for invalid

response codes and the degree of missing data.

• Inconsistent responses were again checked with the original questionnaire.

All data were kept in a locked cabinet and on a password-protected computer.

3.10 Data analysis

Qualitative data: Data analysis was done thematically using open coding,

which is the process of breaking down, examining, comparing, and conceptualizing

data (Strauss & Corbin, 1998) to identify common major themes and sub-themes.

Thematic analysis (Morse & Field, 1996) was chosen as the analytic approach

because the qualitative study stage in this project is exploratory, rather than being

aimed at testing a particular hypothesis about child maltreatment.

Quantitative data: Appropriate statistical analysis was performed using Survey

Data Analysis – SUDAAN 7.5.2a; Analysis of Moment Structures - AMOS 5.0 and

the Statistical Package for Social Sciences - SPSS (version 12 and 14) for Windows.

SUDAAN 7.5.2a was used for calculating design effect to estimate sample size for

the major survey. AMOS 5.0 was used to perform confirmatory factor analysis for

scales measuring depression (CES-D) and self-esteem (RSES). Other specific tests as

described below were undertaken using SPSS version 12 and 14.

80

• Prevalence estimates of different types of child maltreatment and other indices of

interest were provided as the proportion of the entire sample of respondents as

well as for groups of interest, for example, male/female; rural/urban; age groups

and different levels of severity of maltreatment etc.

• Estimates of the magnitude of association between different levels of severity of

various types of maltreatment and risky behaviours were reported as Odd Ratios

(ORs) correlation coefficients (r) for the relationship with physical health and

mental health measures (depression, anxiety, self-esteem).

• Chi-square tests (χ2) and independent t-tests were used to compare the

differences between two groups (for example, gender, region, and age) for

dichotomous and continuous dependent variables respectively.

• Analysis of variance was used to examine the cumulative impact of multiple type

maltreatment experiences on mental and physical health outcomes.

• Logistic Regression modelling was performed to control for possible

confounding to examine the relative impact of each type of maltreatment and

assessment of dose-response relationships between the number of types of

maltreatment and health risk behaviours.

• Multiple Regression modelling was employed to control for possible background

variables to explore the relative effects of child maltreatment on physical and

mental health measures.

Derivation of Variables

• Estimates of participants’ family economic status: We used a proxy measure

asking participants: “In total, how many vehicles (belong to your parent, you and

siblings) does your family have?” Based on their answers we divided their family

economic status into three groups as follows:

High: if families had at least one car.

Medium: if families had one or more motorbikes and no car; and

Low: if families had only one or more bicycles, no motorbike and no car.

81

• Prevalence estimates for particular types of child maltreatment: From the

literature review it is clear that researchers studying child maltreatment continue

to struggle with an optimal operational and compatible definition of each type of

child maltreatment (Manly, 2005). No single definition is likely to be appropriate

for every purpose. Some studies have reported prevalence of various forms of

maltreatment based on response to only a few questions, such as “Being beaten

up, hit with an object, kicked, or some other form of physical force”; “Someone

is intentionally trying to hurt you emotionally with words or actions”; “Someone

in your family or another person does sexual things to you or makes you do

sexual things to them that you don’t want to” (Moran et al., 2004). However,

Bolen and Scannapieco found in their meta-analysis of prevalence of CSA that

such brief measures tend to produce artificially low estimates. Some researchers

have attempted to define severity of maltreatment based on experts’ judgement.

These judgements vary in the importance they place on either frequency of

maltreatment events or a combination of different abusive acts endorsed by

respondents (Arnow et al., 2000; Chen, Dunne et al., 2004; MacMillan et al.,

1997; May-Chahal & Cawson, 2005; Meston et al., 1999; Scher et al., 2004;

Sebre et al., 2004).

Researchers have used a cut–off point (in child maltreatment scales) to classify

maltreated and non-maltreated groups as well as the levels of severity of

maltreatment. Walker and colleagues (1999) identified a cut-off point for the 28-

item short form of the Childhood Trauma Questionnaire for adult sample in the

US using receiver operating characteristic methods with clinician interviews as

the criterion. Other authors used mean score for the cut-off point for each type of

maltreatment (Clemmons et al., 2003; Higgins & McCabe, 2000a; Varia, Abidin,

& Dass, 1996). Gauthier et al. (1996) also used mean as a threshold and mean

plus .55 standard deviation to distinguish between those who experienced low

maltreatment and those who had high maltreatment. To date, the selection of cut-

points has been arbitrary when classifying maltreated groups and levels of

severity in these studies. It may be preferable to give greater weight to

experiences that are considered as more damaging to the victims when defining

82

maltreatment. For example, being kicked or stabbed would be expected to be

worse than being slapped, or a parent saying they wish “you were never born”

would be considered more severe than a parent yelling at you in anger.

Unfortunately, there is not enough empirical evidence to reach consensus on the

differential impacts of these acts for various forms of maltreatment (Bremner,

Vermetten, & Mazure, 2000; Finkelhor, Hamby, Ormrod, & Turner, 2005).

At present, what defines maltreatment is a matter of vigorous debate. There is no

universally accepted criterion for researchers studying child maltreatment in

different countries and study populations to classify severity in estimates of

maltreatment prevalence. One reason is that it is extraordinarily difficult (if not

impossible) to determine a single criterion for severity that is “culture free”. One

imperfect but nevertheless practical alternative is to judge “severity” (e.g.

distinguish between nil, minor, and severe maltreatment) in the basis of variation

in samples drawn from within the population(s). In Vietnam at this time it is not

yet possible (without very extensive further study) to know if there is consensus

among the general public or among the (few) local child protection experts

regarding which combination of events and frequency of acts defines

maltreatment.

In this study, we used the mean score as cut-off point to estimate maltreatment

prevalence as follows: adolescent respondents who scored above the mean and

scored above the mean + 1.0 standard deviation (SD) on the subscales measuring

child emotional maltreatment, physical maltreatment, sexual abuse, and neglect

were classified as having minor maltreatment/unpleasant experience or more

severe level of that type of maltreatment. For example, in the major survey we

used the 5-point physical maltreatment scale with 6 items ranging from never,

rarely, sometimes, often, and always and coded as 1, 2, 3, 4, and 5 respectively.

As a result, the total scores of this scale can range from 6 (if participant

responded never for all 6 items) to 30 (if respondent endorsed always for all

items). The results of mean and SD of this scale in the major survey were 7.85

and 1.95 respectively. Then, physical maltreatment prevalence was estimated as

83

follows: respondents who had mean score equal or higher than 8 but less than or

equal to 10 (10≥mean score≥8) were classified as minor physical maltreatment.

Those with a mean higher than 10 (>10) were considered to have more severe

physical maltreatment. As a result, physical maltreatment prevalence was the

sum of the number of respondents classified as minor and more severe physical

maltreatment.

This approach to defining maltreatment is not perfect. However, one benefit is

that it takes into account the presence of the abusive events and the frequency of

each event. As a result, this could reduce the problem of inclusion of too many

false positives in the maltreated group in comparison with the approach of using

“event/non event” in previous studies. For example, a study in Israel that used the

“event/non event” approach reported more than half of the sample experienced

psychological maltreatment and nearly 90% experienced physical abuse

(Elbedour et al., 2006). In the present study, if we adopted the same approach, the

proportion of adolescents classified at having any experience of at least one event

type (emotional, physical and neglect domains) are also very high (90%, 70%

and 50% respectively, see chapter 4, page 112). In addition, as mentioned earlier,

the use of mean scores as the cut-off point to estimate maltreatment prevalence

takes into consideration the norms of the local population.

In sum, it is recognised that although there are limitations of using the mean (and

mean plus 1.0 SD) as cut-off points for classifying maltreatment, this approach

does at least incorporate a balance between event exposure and severity, and thus

overcomes some measurement problems identified in previous research.

3.11 Ethics approval

Approval to conduct the research was granted from Queensland University of

Technology, Australia and the Hanoi School of Public Health, Vietnam.

84

Before data collection at the two study sites written approval from the Hanoi

Education Bureau, Dongda district Education Department and Chilinh Education

Department was achieved. Information on the research was provided to participating

principals and class teachers and all gave their permission to conduct the study in

their schools and classes. Participants were recruited on a voluntary basis following

informed consent of children, teachers and parents (in the qualitative research stage)

as well as passive consent of parents, whose children voluntarily participated in the

quantitative study. All were advised they could withdraw at any time, and that refusal

or withdrawal would not have an effect on them in any way.

There was the potential for distress among participants during or after data collection

sessions, especially for those who experienced child maltreatment. They could

contact available persons from schools (Youth Union) or Women Union, as the local

communities belonged to a support network for social issues, including children and

women’s issues. The principal investigator contacted the network in advance to

ensure the availability and accessibility of the support service and provided contact

details for participants.

3.12 The qualitative and pilot studies

Qualitative study

The qualitative study included in-depth interviews with teachers, parents and

students (4 teachers: 1 male and 3 females; 4 parents: 2 males and 2 females and 8

students – 4 boys and 4 girls in both lower secondary schools and upper secondary

schools) in both study sites and 8 FGDs (4 FGDs for each study site: 2 groups of

boys and 2 groups of girls from both lower secondary schools and upper secondary

schools) with 6-8 students in each FGD. This work was conducted from January to

March 2004. In-depth interviews lasted between 45 and 60 minutes and the FGDs

lasted about one and a half hours.

85

Eight major themes emerging from accounts provided by students, parents and

teachers including:

• Perception/meaning of child abuse

• Types of abuse

• Different thinking about child physical punishment

• Child maltreatment examples

• Potential perpetrators

• Perceived trend of child abuse prevalence in Vietnam

• Sources of information on child abuse

• Expected measures to prevent child abuse

More details of these common themes are provided in Appendix 8.

The main modifications of the questionnaire following the qualitative study were to:

• Add examples for several questions to help participants to better understand such

as questions about their fathers and mothers occupation (Q12), emotional support

(Q 16) and risky behaviours (Q36 - item g and i).

• Add a clear instruction sentence in section 5 asking about physical abuse (Q43-

Q50).

• Add more detailed options for Q51.6.1 and Q52.7.1 asking about perpetrators

who tried to have, or had sexual intercourse with respondents.

• Change wording in Vietnamese language for Q51 (item a, f, and g) but ensure the

equivalent meaning in the English language version.

The results of the qualitative analysis and comments by children in the draft

questionnaire from FGDs were taken into account to ensure the cultural

appropriateness and clarity of structure, content and wording used in the

86

questionnaire and for interpreting and discussing major study findings from a cultural

perspective.

The pilot study

The pilot study took place at four schools including one lower secondary school and

one upper secondary school in each study site in May and June 2004. All students, in

one grade 7 class and one grade 9 class in each secondary school as well as one grade

11 class in each upper secondary school, resulting 6 classes in total, were invited to

participate in the study. For the pilot study, on the agreed dates with the schools,

research assistants distributed a questionnaire to all students in the selected classes.

To protect confidentiality and to ensure standard administration procedures,

anonymous questionnaires were administered without the presence of class teachers.

First of all, researchers explained the purpose of the research to the children who

were allowed to ask questions related to the research. Then they were asked to

complete the questionnaire to the best of their knowledge. Respondents were

encouraged to participate but it was also made clear to them beforehand that those

who did not want to participate should feel free to decline or could skip portions of

the questionnaire with which they were not comfortable. All participants completed

the questionnaire within 30 minutes. The completed questionnaires were put in blank

envelopes by students. These four schools also participated in the major study.

However, all of the classes that participated in the pilot study were excluded from the

list of classes selected randomly for the major survey.

The pilot study was conducted among 326 participants. Twenty-seven returned

questionnaires missing one section or more than 2 items in any scale were excluded.

Data entry was undertaken for 299 completed questionnaires. The response rate was

91.6 per cent.

87

Sample demographics and family characteristics All respondents were aged between 13-18 years (mean = 15.05; SD = 1.64). The age

distribution of the pilot sample is presented in Figure 3.3. Most students were 13, 15

and 17 years of age (31.1 per cent, n = 93), 15 (29.4 per cent, n = 88), and 17 (33.1

per cent, n = 99). Very few respondents reported their age was 14, 16 and 18 years

because the students recruited for the pilot study belonged to grades 7, 9 and 11

which were equivalent to the age of 13, 15, and 17 respectively.

This sample consisted of 51.8 per cent females and 48.2 per cent males. Almost all

participants belong to the Kinh ethnic majority group (98.7 per cent, n = 295). Most

respondents were living with both their natural parents (88.3 per cent, n = 264).

Small groups of participants were living together with their natural mother or natural

father alone or none of their natural parents (4.3 per cent, n = 13; 2.0 per cent, n = 6;

2.7 per cent, n = 8 respectively). Very few were living with their natural mother and

step father (1.3 per cent, n = 4). Only one respondent (0.3 per cent) was living with

their natural father and step mother. Regarding participants’ parental status, 91.6 per

cent (n = 274) of parents were living together, 3.7 per cent (n = 11) were divorced,

2.0 per cent (n = 6) were separated and 2.3 per cent (n = 7) of parents had died (one

or both). Very few participants (n = 7) said that their parent(s) ever had problems

with drugs or alcohol. Most participants never witnessed a fight between their

parents (82.6 per cent, n = 247). Thirty nine respondents (13 per cent) said that they

were rarely exposed to their parents’ fighting. A few participants (2.7 per cent, n = 8)

were exposed sometimes and only two people (0.7 per cent) witnessed a fight often.

Quality of the scales

Internal consistency

Scale reliability in terms of internal consistency (Cronbach’s Alpha: α) of 8 scales

was calculated and the results are summarized in Table 3.1. The CES-D (20 items)

has been used in many studies of different samples including clinical samples,

general adult samples, adolescent samples in different nations including Asian

countries such as China and Japan, which show good internal consistency with α

range from .81 to 0.89 (Chen, Dunne et al., 2004; Greenberger, Chen, Dmitrieva, &

Farruggia, 2003; Iwata, Saito, & Reberts, 1994; Radloff, 1977). In this study, the

CES-D also shows good internal consistency (α = .87). Psychometric evaluations of

the RSES have shown it to have adequate internal reliability. For this adolescent

sample a reasonable α value was also obtained (α = .78). Reliability in terms of

internal consistency of other scales used in this study was also quite good with alpha

values generally well above .70 and .80 (Pallant, 2001). The only notable exception

was the physical maltreatment scale which had an alpha of .40 (this scale includes 4

items).

The physical maltreatment scale used in this study had two items including several

acts in one item which should be separated into different items such as “locking,

tying up and chaining”, “spanking, kicking, hitting and beating up”. For the main

survey these two items were split into four items resulting in six items in total in this

scale. The improvement of the internal consistency of this scale will be reported in

the chapter on the main survey results.

Exploratory factor analysis of anxiety scale

An exploratory factor analysis was conducted on the anxiety scale using principle

components analysis (PCA). Before performing PCA the suitability of data for factor

analysis was assessed. The Kaiser-Mayer-Oklin value was .82 exceeding the

recommended value of .60, and the Barlett’s Test of sphericity was statistically

significant (.0001), supporting the factorability of the correlation matrix. The number

of factors retained was identified by screeplot and the extracted factors were

subjected to an oblique rotation. The screeplot revealed a clear break of slope

between three and four factors, therefore three factors were rotated. The first three

factors had the following eigenvalues: 3.87, 1.49, 1.19. The rotated loading of

anxiety items on each three components are presented in Table 3.2.

Per cent of variance explained 18.07% 17.44% 13.92%

Only items loading above .50 were used to form the factors. One item (“Nervous

when I have to do some things while people are watching me”) loaded lower than 0.3

in all factors and was removed. Factor 1 (4 items) accounted for 18.07 per cent of the

variance, factor 2 (5 items) for 17.44 per cent of variance and factor 3 (4 items) for

13.92 per cent. Three factors of this anxiety scale were named fears, tension and

worries which are reliable in terms of internal consistency with Cronbach’s Alphas

are .72, .64; and .62 respectively. The results of the analysis support the use of the

anxiety scale (13 items) to screen for this mental health problem in the adolescent

sample in the major survey.

91

Confirmatory factor analysis of depression and self-esteem scales

Confirmatory factor analysis (CFA) was employed using AMOS 5.0 to test the extent

to which the CES-D and RSES data from this pilot sample conformed to the factor

models; four factors for CES-D (Radloff, 1977) and two factors for RSES

(Greenberger et al., 2003), obtained in previous studies. Radloff (Radloff, 1977)

named CES-D’s four factors as depressed affect (7 items), positive affect (4 items),

somatic and retarded activity (7 items), and interpersonal (2 items). Two factors of

RSES contain five positively worded items and five negatively worded items. The

results of CFA conducted for these two scales are presented in Table 3.3. The factors

of these two scales were specified as intercorrelated (See Appendix 9) and goodness

of fit was determined on the basis of several indices: Chi-square (χ2), comparative fit

index (CFI), goodness-of-fit index (GFI), normed fit index (NFI), and root mean

square error of approximation (RMSEA). The Chi-squared test of overall model fit is

required to be non-significant which implies that the model fits. However, as

suggested by researchers that due to its sensitivity to sample size, non-normality and

model complexity, even small differences in model fit are statistically significant. It

may therefore have been unrealistic to use χ2 test as the index of fit. However, a

range of indices, as mentioned above, associated with the χ2 test could be used to

assess the extent to which these scales fit with original models (Nguyen, Kitner-

Triolo, Evans, & Zonderman, 2004; Wells & Cartwright-Hatton, 2004).

Table 3.3: Pilot study: Summary of the fit statistics of CES-D and RSES

Scales χ2 df GFI CFI NFI RMSEA

CES-D 1371* 164 .944 .912 .901 .053

RSES 281* 34 .978 .948 .941 .053

* p< 0.05

The GFI compares the postulated model with no model and its value range from 0 to

1 (with values closer to 1 representing a good fit). The NFI quantifies the amount of

92

variation and covariation accounted for a particular model by comparing the relative

fit of the given model with the fit of a baseline model (NFI ranges from 0 to 1).

Higher values indicate greater covariation accounted for; values above .90

determines an excellent model (Bentler, 1992). CFI, measuring the quality of model

fit with a value more than .90 indicating a good fit of the data, is independent of

sample size, and takes the complexity of the model into account and compares the

baseline model with the independent model. RMSEA takes into account the error of

approximation in the population. Values less than .05 present a good fit, 0.06-0.08

indicate reasonable fit. Recently, RMSEA has been recognised as one of the most

informative criteria in covariance structure modelling (Byrne, 1998; Nguyen et al.,

2004).

CFA results from our pilot study demonstrated that the same four-factor model of

CES-D and two factor model of RSES could be replicated in our adolescent sample.

This supports the use of these scales to measure depression and self-esteem in the

major survey.

Maltreatment experiences

Table 3.4 and table 3.5 depict frequencies of different items included in the scales

measuring emotional, physical, sexual maltreatment and neglect. Participants’

responses to almost all items and generally frequencies reduced according to the

level of severity. Only one item in the sexual abuse scale had no response “made you

see sexual scenes in reality”. Therefore this item was removed in the final

questionnaire.

Missing values of each item are quite low (from 0 to 1.3 per cent). It is clear from

this result that participants in this study were willing to respond to questions

regarding a sensitive topic. Non-response rate to child sexual abuse events (0.3 to 1.0

per cent) is the same as other forms of maltreatment (0.3 to 1.3 per cent).

93

After asking sexual acts experienced, participants were asked a question “How old

were you the first time any of these things happened?”. Age at the first time any of

the sexual acts happened ranges from 5 to 17 years with the highest rate at 12 years

of age (19.5 per cent, n = 8/41), then at 15 years of age (14.6 per cent, n = 6/41), and

at 10 years of age (12.2 per cent, n= 5). However, the feedback of research assistants

that participants had difficulties when answering this question as those who

experienced several acts reported they could not determine which act they should

provide information about the age when these adverse sexual acts happened. In the

final questionnaire we therefore collected separate information concerning age at

first sexual abuse experience for attempted rape and rape events only.

Prevalence of particular types of child maltreatment was calculated as described in

the previous section entitled Derivation of variables (page 81-82) and presented in

Table 3.6 according to gender and region. It is clear that child maltreatment in this

population is not uncommon. The most common form is physical abuse (58.9 per

cent), while emotional abuse and neglect is self-reported by approximately 40 per

cent to 50 per cent of the participants. Prevalence of sexual abuse is approximately

18 per cent for this sample. Surprisingly, the rate of sexual abuse among males was

higher than females in both urban (male: 24.6 per cent; female: 17.3 per cent) and

rural (male: 16.5 per cent; female: 12.8 per cent) areas.

Four forms of maltreatment 5.1 7.0 6.1 6.2 5.8 6.0

97

The prevalence estimates of multiple forms of abuse are presented in Table 3.7. It

can be seen that in total approximately 80 per cent of the respondents experienced at

least one form of maltreatment although it is acknowledged that this would include

rare or occasional and possibly mild adverse experiences. Approximately 30 per cent

of participants reported three and four forms of maltreatment experiences.

Correlates of maltreatment with health outcomes: Bivariate analysis

Statistically significant associations were detected between different forms of

maltreatment and various health outcomes. The correlation coefficients are presented

in Table 3.8 below.

** Correlation is significant at the 0.01 level (2-tailed)

Differences between maltreatment experience groups and mental health outcomes

A one-way between-groups analysis of variance was conducted to examine the

associations between abuse experiences and mental health symptoms (depression,

anxiety and self-esteem). Across types of maltreatment respondents were divided

into three groups (group 1: no maltreatment, group 2: minor maltreatment, and group

3: more severe maltreatment; see Table 3.6). Post-hoc comparison using the Tukey

test indicated that there were statistically significant differences in most of the

98

comparisons except physical abuse and sexual abuse and self-esteem, and sexual

abuse and anxiety (see Table 3.9)

Calculating design effect for cluster sampling Based on the data collected from the pilot study with the estimated prevalence of

each type of child maltreatment, total depression, anxiety, self-esteem, and physical

health problem scores as the outcome variables, the design effect for each variable

were calculated using statistical package (SUDAAN 7.5.2a). The result shows that

design effects were approximately 1.0. It means that it is no need to take into account

an inflation factor for clustering in our sample calculation and analysis in the main

survey.

Calculating sample size To determine sample size for the main survey the formula estimating the difference

between two population proportions with specified absolute precision was employed

(Lwanga & Lemeshow, 1991).

99

• Power of 90%

• Significance of 5%

Sample size per group = Z2 1-α/2 [P1 (1 - P1) + P2 (1 – P2)]/d2

where P1 is the proportion expected in group 1 (boys) and P2 is the proportion

expected in group 2 (girls); d is the minimum detectable difference = 0.07 (for this

study)

From the pilot data a possible sample size for each type of maltreatment to detect the

difference in proportion between boys and girls who experienced that type of

maltreatment was calculated. Results show that biggest sample size (1,150 for each

group) was required in order to detect the difference of physical maltreatment

experienced by boys and girls (with P1 = 63.2 per cent, and P2 = 54.9 per cent). From

the pilot survey it was known that the rate of non response was about 10%. Hence,

1265 students in each group would be required, resulting in a total of about 2,500

participants.

3.13 Implications of the pilot study

Data collection procedure

Results of the pilot study confirmed that the procedure for data collection proposed

was appropriate. However, reports from research assistants after conducting the data

collection revealed that some teachers assumed they had the responsibility to collect

data in the class even though we sent them study information and requirements in

advance. To overcome this in the main survey, apart from making sure that teachers

did receive study instruction information, we required research assistants to

personally meet with teachers just before conducting data collection sessions in their

classes to ensure this procedure was followed.

Timing for conducting data collection was also very important. Feedback from the

pilot study revealed that optimal times for data collection were not those days close

100

to the time of regular exams, the beginning of the week or the beginning of a day’s

study session.

Findings

Preliminary findings drawn from the results of the pilot study which informed the

refinement of the main survey instrument and data collection procedure included:

• The instrument developed and selected appears to be validated for use in this

adolescent sample. However, results of the pilot study did show that changes

needed to be made to improve the quality of the questionnaire. Details of these

changes will be presented in the following section.

• Child maltreatment in this adolescent sample is not uncommon and the

prevalence of various forms of maltreatment is comparable with previous studies

in other countries.

• The rate of respondents who reported multiple forms of maltreatment experiences

were not uncommon.

• It is clear that participants were willing to participate in the research related to a

sensitive topic and disclose their unpleasant experiences. Missing data was low

and non response rate of sexual abuse questions was similar to that of other types

of child maltreatment questions

3.14 Changes to the questionnaire

Apart from changes that had been made after the qualitative study already described,

a number of changes were made to the questionnaire following the pilot study. These

included:

• Removal of some questions which were unrelated to major research questions.

• Removal of one item in the sexual abuse scale because no respondent reported

this experience in the pilot study and one item in the anxiety scale based on the

result of exploratory factor analysis.

101

• Adding a question as a proxy to measure economic status (number and type of

vehicles belonging to family members)

• Sessions asking respondents about their experiences of four forms of

maltreatment in part D “Your experiences” was moved to the end of this part

after sessions on physical and mental health and health risk behaviours.

• Physical maltreatment scale was revised (from four items to six items and

removal of some sub-question in this scale.

• Change of question asking about age the first time sexual abuse event occurred.

The final questionnaire consisted of four parts: demographics, family characteristics,

school information, and childhood experiences including self-reported physical

health, mental health and health risk behaviours, emotional maltreatment, neglect,

physical maltreatment, and sexual abuse. The full final questionnaire can be found in

Appendix 7.

102

Chapter 4: Prevalence and Characteristics of

Different Forms of Abuse

The following chapters present the results from the major study. As indicated in

Chapter 3, the study was designed to maximise the quality of data collection,

especially disclosure of maltreatment experiences based on ensuring the data

collection procedures and validating the questionnaire.

The main survey was conducted between December 2004 and May 2005. All eight

randomly selected schools were contacted and agreed to participate in the study

resulting in a school response rate of 100%. In total 2,737 students from 61 classes

were invited to participate in the study. Sixty-five students were absent from classes

on the days the data collection took place and 81 returned incomplete questionnaires.

Therefore the response rate of students was 94.7%. The final analysis was based on

data from 2,591 students, after questionnaire with incomplete data were excluded.

The key research questions addressed in this chapter are:

• What is the prevalence of sexual abuse, physical maltreatment, emotional

maltreatment and neglect in the school adolescent sample?

• Is the prevalence of child maltreatment of various forms among adolescents in

school setting significantly different between urban (Dongda district) and rural

(Chilinh district) area.

• Is the prevalence of four forms of child maltreatment significantly different

between these school boys and girls?

• What are the correlations between each form of child maltreatment and various

demographic variables, family characteristics and environment?

103

4.1 Sample characteristics

Demographic characteristics

Table 4.1 displays the demographic characteristics of the sample. The sample

consisted of 1,335 (51.5%) students from the urban area and 1,256 (48.5%) students

from the rural area. Females represent 52.1 % (n = 1,350) and males 47.9 % (n =

1.241). The age range was between 12 and 18 (mean = 14.99, SD = 1.47) in which

98.7% were between 13 to 17 years old. Almost all respondents belonged to the Kinh

majority group of people (99.1%, n = 2,568). About ninety per cent (n = 2,351) of

participants reported that they did not belong to any religion.

104

Less than one in ten participants (7.3%, n = 188) come from high economic status

families and 14.1 % (n = 364) come from low economic status families. The rest

(78.6%, n = 2,003) have a medium family economic background.

Family characteristics Characteristics of respondents’ families are presented in Table 4.2. Most of the

respondents have their parents living together (90.6%, n = 2,347). A small proportion

of 4.4% participants’ parents are divorced (n = 115) and the rate of separated couples

was just over one per cent (n = 29). Nearly a hundred of participants’ parents (3.7%)

were deceased (one or both).

Respondents’ parent education is divided into six groups. Twenty five percent (n =

656) of participants’ mother and about thirty one per cent (n = 809) of respondents’

fathers hold a university or a college degree. Nearly twenty per cent (18.1%, n = 469)

of mothers and 15.7 % (n = 407) of fathers had completed technical and vocational

education. Completion rates for upper secondary schools were about the same

(32.9%, n= 852 and 32.5 %, n = 843 respectively) for mothers and fathers.

Completion of secondary school rates were 20.9% (n = 542) and 18.7% (n = 484) for

mothers and fathers. A small number of parents attended only primary schools

(mothers: 2.6%, n = 67 and fathers: 1.9%, n = 48). Five mothers (0.2%) had never

gone to school.

A significant proportion of respondents’ parents were working for the government

(33.8% mothers and 43.7% fathers). The proportion of parents who were self-

employed is 20.6% (n = 535) for mothers and 25.5% (n = 663) for fathers. The rate

of mothers and fathers who were farmers accounted for 19.5% (n = 506) and 17.2%

(n = 446) respectively. A significant proportion of mothers (n = 571, 22.0%) were

homemakers whereas only 3.9% (n = 100) respondents reported their fathers as

homemakers. A small number of respondents identified their parents were

unemployed (0.6% mother and 1.9% father). Eighty one respondents (3.2%) reported

that their parents had problems with drugs and/or alcohol.

Most respondents (86.6%, n = 2,239) were living with both their natural parents.

Small proportions of children were living with only their natural mother (6.1%, n =

156), their natural father (1.8%, n = 47), natural mother and stepfather (0.8%, n =

20), natural father and stepmother (0.8%, n = 21), and 3.9% (n = 99) respondents

were not living with their natural parents. Only 11.4% (n = 296) respondents reported

that they were the only child in their family. Most respondents (70.1%, n = 1,812)

had one brother or sister and 18.4% (n = 471) participants come from families with

three or more children.

Participants of this study were also asked questions regarding their family

environment including parent quarrelling and fighting; their source of emotional

support (Who do you most often talk to when you need help e.g. sharing feelings,

asking for advice?), and their perceived parental relationship. Their responses are

presented in Table 4.3 below.

About one third of the respondents (29.7%, n = 767) had experienced no parent

quarrels at all in their lifetime. A significant proportion of participants (42.4%, n =

1,093) rarely observed verbal conflict between their parents. And nearly one in three

respondents reported that their parents quarrelled more frequently (sometimes:

24.8% and often: 3.1%). Most respondents (75.1%, n = 1,936) said they had never

witnessed parental fighting. One in four participants reported that their parents

fighting was observed rarely (17.4%), sometimes (6.7%) or often (0.8%).

107

Most respondents perceived their families were very happy (26.7%, n = 690) or

happy (52.4%, 1,353), while a small number of participants considered their parental

relationship was unhappy (3.7%, n = 93) or very unhappy (1.0%, n = 26). However,

there were a significant proportion of participants (16.2%, n = 418) who could not

comment on the quality of their parents’ relationship.

As far as emotional support was concerned, we asked participants: “who do you talk

to when you need help?”, friends were the main source for about 40% (n = 1,044) of

respondents. Participants’ mothers and brothers/sisters accounted for 17.3% (n =

447) and 14.6% (n = 378) respectively. A small number of participants were mainly

seeking help from fathers and relatives (4.4%, n = 114 and 2.0%, n = 53). There were

108

nearly a quarter of participants (19.1%, n = 496) who had no one to support them

emotionally.

4.2 Adverse experiences and prevalence of four forms of child maltreatment

In this section adverse experiences reported by respondents are presented first

according to every act included in four scales to measure emotional maltreatment,

physical maltreatment and neglect with rating ranging from never to always, and

sexual abuse with rating ranging from never, once to more than once. Then the

prevalence of the four forms of abuse was calculated according to the method

described in Chapter 3.

Reliability, in terms of internal consistency (Cronbach’s alpha), of the scales

measuring emotional, physical maltreatment, sexual abuse and neglect calculated

based on data from the main survey and results are follows:

• Emotional abuse scale (Mean = 11.87, SD = 3.74): α = 0.81

• Physical abuse scale (Mean = 7.85, SD = 1.95): α = 0.63

• Sexual abuse scale (Mean = 9.26, SD = 2.75): α = 0.75

• Neglect scale (Mean = 9.15, SD = 3.71): α = 0.78

Adverse experiences

Frequencies of series of adverse acts ever experienced by respondents are reported in

Table 4.4, Table 4.5, Table 4.6, and Table 4.7.

111

The proportions of respondents who experienced at least one adverse event of each

scale were approximately 90%, 70%, 50% and 25% for emotional, physical, neglect

and sexual scales respectively.

Just above three per cent (3.2%) participants had ever experienced attempted rape

once or more than once. And 2.7% respondents reported that they were raped once or

more than once.

Prevalence of child maltreatment

As discussed in chapter 3 about defining the prevalence of different forms of child

maltreatment, for the purpose of this study mean was used as cut-off point for

calculating prevalence: adolescent respondents scored above the mean and scored

above the mean +1.0 standard deviation on the subscales measuring child emotional

maltreatment, physical maltreatment, sexual abuse, and neglect were classified

having minor maltreatment/unpleasant experience or more severe experiences of that

type of maltreatment. It is therefore very important to note that with this approach it

did not mean that respondents who were considered to be not maltreated of any

maltreatment form did not experience any adverse event of this maltreatment scale.

The prevalence of child maltreatment is displayed for the whole sample and for

females and males in two regions separately according to the level of severity (minor

maltreatment and more severe maltreatment) in Table 4.8.

About forty per cent of respondents experienced emotional maltreatment. Prevalence

of emotional abuse is similar between urban and rural areas (39.6% and 39.1%

respectively). However, as we can see in the table female in both regions were

experienced this type of maltreatment more than males.

Nearly half of the sample reported physical maltreatment experiences (47.5%) with

higher proportion among male than female in both regions.

112

Approximately one-fifth (19.7%) of the respondents met the criteria for sexual abuse.

Interestingly, prevalence of sexual abuse was higher in the rural area (22.0%) than in

the urban area (17.6%). And, the proportion of males (26.0%) in the rural region

reported sexual abuse experiences significantly higher than their female counterparts

(18.3%). In contrast, female participants in the urban area reported slightly higher

sexual abuse experiences (18.5%) than male participants (16.4%).

113

Just under one-third of participants of the whole sample experienced neglect

(29.3%). The neglect rates were significantly higher among female (urban: 36.1%,

rural: 30.5%) than male (urban: 26.1%, rural: 23.6%) in the two areas. (Appendix 10

summarises proportions and confidence interval for each form of child maltreatment

for Chilinh, Dongda sub-samples and for the whole sample).

Co-occurring maltreatment prevalence is summarized in Table 4.9 for the whole

sample and for females and males in two areas separately. The prevalence of co-

occurrence of child maltreatment was calculated as follows: the number of types of

child maltreatment to which a respondent reported experiencing was summed up.

This summary measure, the co-occurrence maltreatment score, range from 0

(experienced no maltreatment) to 4 (experienced 4 forms of maltreatment).

About two-thirds (67.5%) of the respondents experienced at least one form of

maltreatment. Just one in four and one in five participants suffered one form of

maltreatment (25.9%) and two forms (20.7%) of maltreatment respectively. Nearly

fifteen per cent of respondents reported three forms of maltreatment experience and

about six per cent participants met criteria for all forms of child maltreatment.

Significantly higher proportions of co-occurrence of the three forms of abuse were

reported by respondents in urban area (16.1%) than their counterparts in rural area

(12.8%). Females in urban area experienced a co-occurrence of the three forms of

abuse (18.1%) significantly higher than that of males (13.9%).

4.3 Characteristics of child maltreatment

Emotional maltreatment

Perpetrator detail was asked for the most severe adverse event. Respondents were

asked: “When you grew up, did any adults in your family threaten to hurt or kill you?

And if this ever happened who often did this?”. Approximately three hundred and

fifty (13.3%, n = 347)) respondents reported that they experienced this event. Three

hundred and nineteen respondents answered the question about the identity of the

perpetrator (8.1% missing data, n = 28). The most commonly perpetrators reported

were father (30.5%, n = 106), mother (26.5%, n = 92), siblings (16.7%, n = 58), and

relatives (7.7%, n = 27).

Physical maltreatment

Generally speaking, perpetrators of unwanted physical events were father, mother,

siblings, relatives, and neighbour in this order except for pushing, grabbing and

throwing events. Detailed results of perpetrators are summarized in Table 4.10.

Consequences of experiencing any adverse physical event were also reported. Of

1,750 participants responded to the question “how often these incidents give you

bruises or scratches, broken bone or loss teeth”, about one in five (21.3%) reported

that it happened rarely, 7.4% sometimes, 1.7% often and 0.3% always.

Approximately one in ten (11.0%) respondents had rarely needed medical treatment

due to experiencing unwanted physical events. Just above three per cent (3.4%) of

participants who experienced unwanted physical incidents sometimes required

medical intervention. Less than one per cent reported often (0.43%) or always

(0.12%) needed medical treatment after experiencing adverse physical acts.

116

Sexual abuse

The majority of the perpetrators of attempted rape (3.2%, n = 82) and rape (2.7%, n =

71) were male and female strangers, neighbours, fathers, male cousins, mothers, and

brothers and sisters (see Table 4.11)

The mean age of the first time of attempted rape described was 12.3 years (SD 2.54)

ranging from 5 to 17 years old. Similarly, the mean age of the first time rape reported

was 12.2 years (SD 3.35) ranging from 1 to 17 year olds.

4.4 Correlates of child maltreatment

A series of univariate logistic regression analysis and χ2 test for categorical data were

performed to examine the association between each form of maltreatment, divided

into two groups: maltreated and not maltreated, and demographic characteristics,

parent characteristics, child characteristics, and family environment variables.

117

Demographic correlates of child maltreatment Tests of statistical significance, odds ratios, and 95% confidence intervals for

potential demographic correlates of four types of child maltreatment are displayed in

Table 4.12, Table 4.13, Table 4.14, and Table 4.15.

For emotional maltreatment, gender and age emerged as significant correlates. Girls

were more likely to report history of emotional abuse than boys (OR = 1.30). The

risk of emotional abuse significantly increased when adolescents grew up (OR = 1.40

for group aged 14-15, and OR = 1.62 for group aged >15) (see Table 4.12)

Child sexual abuse was significantly correlated with region and child family

economic status. Adolescents in Chilinh (rural area) were more likely to report a

history of sexual abuse than adolescents in Dongda (urban area) (OR = 1.32).

Children who came from medium family economic background (OR = .74) were less

at risk of sexual abuse than children from low family economic background (see

Table 4.14).

Child neglect was associated with region, gender and age. Unlike sexual abuse,

children in urban areas were more likely to experience neglect (OR = 1.23), and for

the total sample females are more at risk than males regarding child neglect (OR =

1.51). The more adolescents grew up the more they reported neglect experience (OR

= 1.5 for age group 14-15, and OR = 1.94 for age group 16 to 19). Interestingly,

family economic status was not significantly related to neglect (see Table 4.15).

Family characteristic correlates of child maltreatment

Due to the small number of mothers who classified their education as never went to

school/no formal education (n = 5) and completed primary school (n = 67) these

number were combined to explore the associations between this variable and

experiences of child maltreatment.

Table 4.16 summarizes the odds ratio and confidence intervals of correlates between

each form of maltreatment and family characteristic variables. For emotional

maltreatment, adolescents from divorced families (OR = 1.76) or whose parents had

died (one or both) (OR = 158) were more at risk. Adolescents whose mothers had

121

completed high school (OR = 1.35) and fathers completed technical and vocational

education (OR = 1.34) were more likely to report a history of emotional

maltreatment. Regarding parent occupation, only adolescents with self-employed

mothers were significantly more likely to report emotional maltreatment experiences

(OR = 1.29). Respondents reported their parents’ drugs and/or alcohol problems were

more likely to lead to risk of emotional maltreatment (OR = 2.54). Child emotional

maltreatment is also significantly associated with whom respondents were living

with. Children who were living with only their natural mother (OR = 1.76), natural

mother and stepfather (OR = 3.03), and natural father and stepmother (OR = 2.65)

were more likely to report emotional abuse experiences.

*p<.05; **P<.01; ***p<.001 For physical maltreatment, as displayed in Table 4.16 parent marital status, mother’s

education, father’s education, parent occupation, and living arrangements were

significantly associated with child physical maltreatment. Children from divorced

families (OR = 1.61), children whose mothers completed secondary school (OR =

2.02) and fathers completed technical college (OR = 1.35) or high school (OR =

1.22), mother unemployed (OR = 3.64) and parents working as farmer (OR = 1.28

for mother as a farmer, and OR = 1.25 for father as a farmer) as well as living with

only their natural mother (OR = 1.45) were more likely to report a history of physical

maltreatment.

Parental divorce significantly increased the risk of child sexual abuse (OR = 1.85).

Fathers who had completed secondary school (OR = 1.33), or fathers worked as a

farmer (OR = 1.32), mother completed secondary school (OR = 1.83) and mothers

worked as self-employed (OR = 1.38), or farmer (OR = 1.42), and unemployed (OR

124

= 2.93), parent alcohol and/or drug problems (OR = 2.09) as well as children living

with natural mother and stepfather (OR = 3.18) were emerged as significant

correlates with child sexual abuse.

Similar to child emotional maltreatment, adolescents from divorced families (OR =

2.04) or their parents had died (OR = 1.58), self-employed mother (OR = 1.27) or

parent with drugs and/or alcohol problems (OR = 1.78) were significantly more

likely to report history of neglect. Children living with only natural mother (OR =

1.55), natural father and stepmother (OR = 4.24) or none of natural parents (OR =

1.69) were significantly more likely to have experienced neglect.

Family environment correlates of child maltreatment

In general, all variables regarding family environment measured in this study

including parent quarrelling, parent fighting, perceived parental relationship, and

source of emotional support were found to be significantly associated with four

forms of child maltreatment. The results are displayed in Table 14.17. Children

looking for emotional support from their friends, other sources or from nobody were

significantly more likely to experience maltreatment, except for sexual abuse

whereby only respondents seeking for emotional advice and help from friends (OR

=1.56) were significantly likely to report sexual abuse.

Multivariate analysis of predictors of child maltreatment

After exploring bivariate correlations between a series of variables of demographics,

family characteristics, family environment and four types of child maltreatment, all

the variables that were significant in the univariate models were entered into the

multivariate logistic regression model simultaneously. The final multivariate logistic

regression models included all variables retaining significance after adjusting for

each other. Statistical test of the regression estimates or odds ratios were based on

Wald statistics. Results of multivariate logistic regression are summarized in Table

4.18, Table 4.19, Table 4.20 and Table 4.21 (only statistically significant variables

included) for emotional, physical, sexual abuse and neglect respectively.

As can be seen in Table 4.18, after controlling for the effects of other correlates

examined, females, older adolescents, children coming from divorced families,

parent with drug or/and alcohol problems, violence between parents, children living

only with natural mother or with natural father and step mother, and children mainly

seeking emotional support from other sources than mother and brother/sisters were

more likely to experience emotional maltreatment.

4.5 Summary

This chapter has presented a wide range of information including characteristics of

the major survey sample, percentage of adverse childhood events, prevalence of four

forms of child maltreatment as well as prevalence of multiple forms of child

maltreatment. Correlates of demographic characteristics, family characteristics and

family environment with child emotional, physical, and sexual maltreatment and

neglect have also been reviewed thoroughly by both univarite and multivariate

logistic regression. After controlling for effects of other examined variables the

results show that:

• The prevalence of child maltreatment of various forms among adolescents in

school settings was not significantly different between urban (Dongda district)

and rural (Chilinh district) areas except for sexual abuse. Children from the rural

were more likely to report unwanted sexual experiences than their counterparts in

the urban areas.

• Girls were more likely to report emotional maltreatment and neglect than boys,

while boys were more likely to experience physical maltreatment. And for sexual

abuse, there were no significant gender differences.

• Gender (except for sexual abuse) and family environment variables including

parental quarrelling, fighting, perceived quality of parental relationship, and

emotional support, appeared to be the most consistent factors significantly to

predict each form of child maltreatment.

132

Chapter 5: Associations between Child Maltreatment and Health Risk

Behaviours

This chapter addresses the following research questions:

• What are the differences in health risk behaviour prevalence between female and

male adolescents and among adolescents attending urban and rural secondary

schools and across age groups?

• What are the associations between self-reported history of emotional

maltreatment, physical maltreatment, sexual abuse and neglect and risky

behaviours?

• To what extent does the co-occurrence of childhood maltreatment experiences

correlate with health risk behaviours?

The literature review indicated the potential for child maltreatment victims to engage

in taking health risk behaviours such as smoking, drinking, eating disorders, carrying

weapons, fighting and suicidal plans or actions. The study questionnaire included

eleven items about recent and life time risky behaviours.

5.1 Prevalence and correlations of health risk behaviours

Overall, 17.6% of the sample reported that in the past 12 months, they had felt so sad

or hopeless almost every day for two weeks or more that they stopped doing some

usual activities. For intentional injury, approximately 9% of respondents had

seriously considered attempting suicide and 6% had made a specific suicide plan, and

nearly 10% of students had been involved in a physical fight in the past 12 months.

133

More than 4% of participants ever smoked cigarettes, about 9% had drunk alcohol in

the past 30 days, and 9% had ever been drunk during their lifetime. A small

proportion of participants (2.8%) reported having been injured while drunk. The rate

of participants attempting to lose weight in the past 30 days also was quite low

(3.6%). The prevalence of carrying weapons during the past 30 days was 3.2%. In a

school setting, 6.4% of the sample reported being threatened or injured in the past 12

months.

Chi-squared (χ2) tests were performed to examine gender and regional differences in

the prevalence of various health risk behaviours. As shown in Table 5.1, there were

statistically significant associations between gender and all eleven items of health

risk behaviours. A greater proportion of female students had the experience of

feeling sad or hopeless, considered attempting suicide or had made a suicide plan,

but male students were more likely to carry a weapon, to be threatened in school

setting and to be involved in physical fights. A much higher proportion of boys

smoked, consumed alcohol, had ever been drunk or injured while drunk. However,

girls were more likely to consider themselves overweight, and to be trying to lose

weight by not eating for 24 hours or so in the past 30 days.

The relationships between rural and urban areas and health risk behaviours were

examined and are presented in Table 5.2. Generally, rates of health risk behaviours

were similar in these two regions, although urban adolescents were more likely to

report attempted suicide, smoking cigarettes, and drinking alcohol.

Univariate logistic regression models were conducted to examine the correlations

between age and health risk behaviours, with a group of 12-13 year olds as the

reference group. Results are presented in Table 5.3.

Older students were significantly more likely to feel sad or hopeless. Even though

suicidality prevalence, rates of students carrying weapons and being threatened in

school were highest among students at the age of 14-15 years, there was no

statistically significant difference among the 3 age groups.

Prevalence of smoking, drinking and ever being drunk during lifetime markedly

increased with age. But students aged 16-18 years were significantly less likely to be

injured while drunk or to be involved in physical fights.

5.2 Associations between maltreatment types, multiple forms of maltreatment and health risk behaviours

To estimate the effect of each type of maltreatment as well as the impact of co-

occurrence of child maltreatment on health risk behaviours, it is essential to control

for variables known to potentially influence risky behaviours such as demographic

variables, family characteristics, parent and child characteristics.

137

A series of logistic regression analyses were conducted to examine the potential

impact of child maltreatment on each health risk behaviour according to gender.

Initially, all potential risk factors were explored in bivariate logistic regression

models. All the variables that were significant in the bivariate analysis were then

entered into the multivariate logistic regression models sequentially. All significant

demographic, family, parent and child variables were entered in first step. Then four

types of child maltreatment (categorized in three groups: no maltreatment, minor

maltreatment and more severe maltreatment) were entered in the second step.

Similarly, this approach was also used in examining the correlations between co-

occurrence of child maltreatment and each of the health risk behaviours. A multiple

maltreatment variable was created whereby each individual was categorized in one of

five groups (no maltreatment, one to four types of maltreatment). This was entered in

the second step in each multivariate logistic regression model. Statistical tests of the

regression estimates or odds ratios were based on Wald statistics.

The analyses were stratified by gender. As there were small numbers of female

students exposed to smoking (n =20), ever injured while drunk (n = 16), and carrying

weapons (n = 17), the association between child maltreatment and those behaviours

was not examined. Similarly, less than 30 male students reported not eating for 24

hours or so to lose weight, so this behaviour was omitted in the analysis. As a result,

the correlations between child maltreatment and 8 health risk behaviours for females

and 10 health risk behaviours for males were examined in this study.

Due to relatively small numbers of respondents in several subgroups of some

questions, combinations of subgroups was undertaken to ensure that no two-way

table had more than 20% of the cells with frequencies less than 5, nor any expected

frequencies less than 1. In this case no restriction applied to evaluating the model

goodness-of-fit criteria for logistic regression models (Tabachnick & Fidell, 2001).

The following eleven variables had their subgroups combined compared with the

original questions:

138

• Respondents’ age was divided into three groups (12-13 years, 14-15 years, or 16-

18 years).

• Parent’s marital status was measured in two categories (parents living together or

parents not living together including divorced, separated or died).

• Family arrangement was categorized in three groups (living with both natural

parents, living with one natural parent, or living with no natural parent).

• Mother and father’s education was divided into four groups (university/college

degree, completed technical/vocational education, completed high school, or

completed secondary school and lower).

• Mother and father’s occupation was categorized into five groups (government

staff, self-employed, farmer, homemaker, or unemployed/others).

• Parent physical fighting was collapsed into 3 groups (never, rarely, or

sometimes/often).

• Perceived quality of parental relationship was measured in a four point scale

(very happy, happy, not sure, or unhappy/very unhappy).

• Child academic achievement was truncated to 3 levels (excellent, good, or

fair/poor).

• School punishment was scaled in 3 levels (never, rarely, or sometimes/more).

• Self-perception of health status was reduced to 4 categories (very good, good,

fair, or poor/very poor).

• Source of emotional support was divided into 5 groups (mother/father,

brother/sister, friends, relatives/others, or none).

In total, 8 multivariate logistic regression models for females and 10 models for

males were fitted to explore the relationship between each type of child maltreatment

and health risk behaviours. The same numbers of logistic regression models were

performed to examine the impact of co-occurrence of child maltreatment and each of

the health risk behaviours.

Omnibus Tests of Model Coefficients, and Hosmer and Lemeshow Tests were used

to test the goodness-of-fit of each model. Omnibus Test of Model Coefficients

indicates how well the model performed compared with none of the predictors

139

entered in to the model and this test needs to be statistically significant (p<.05)

(Pallant, 2004). To support the goodness-of-fit of the model, the Hosmer and

Lemeshow Test should be non-significant (p>.05) (Tabachnick & Fidell, 2001). All

the multivariate logistic regression models satisfied these two goodness-of-fit tests.

The results of multivariate logistic regression analyses showing the relationships

between four forms of child maltreatment: emotional maltreatment (female, n =

1,350; male n = 1,241), physical maltreatment (female, n = 1,350; male n = 1,241),

sexual abuse (female, n = 1,349; male n = 1,241), neglect (female, n = 1,350; male n

= 1,241), and co-occurrence of child maltreatment (female, n = 1,344; male n =

1,238) and each of the health risk behaviours by gender are presented below.

Felt sad and hopeless

Fourteen confounding variables including parent marital status, family arrangement,

number of siblings, mother and father’s education, father’s occupation, parental

quarrelling and fighting, perceived parental relationship, emotional support,

academic achievement, diagnosed chronic disease, self-perception of health status

and body satisfaction were first entered and then 4 forms of child maltreatment or

multiple forms of child maltreatment were entered in the second step in each model

to explore the correlation between each type of child maltreatment and co-occurrence

of maltreatment and feeling sad or hopeless in the female sample. Similar procedures

were applied for the male sample, however the controlled variables were region,

parent occupation, parental quarrelling and fighting, emotional support, academic

achievement, school punishment, and self-perception of health status. Table 5.4

shows the adjusted relationships between individual types of child maltreatment, co-

occurrence of child maltreatment and feeling sad for female and male students. More

severe emotional maltreatment and neglect significantly predicted sad and hopeless

feelings for both female (CEA: OR = 1.81; CN: OR = 2.43) and male (CEA: OR =

3.28; CN: OR = 1.74) respondents. Minor emotional maltreatment and neglect also

significantly increased the risk of feeling sad for male participants (CEA: OR = 2.08,

CN: OR = 1.61). Being exposed to physical and sexual maltreatment was also

140

associated with sad feelings of both females and males. Statistical significance was

only detected with minor physical maltreatment of female participants (CPA: OR =

1.56).

For multiple forms of child maltreatment, Figure 5.1 clearly shows that the more

respondents were exposed to co-occurrence of maltreatment, the more they felt sad

and hopeless. These findings are statistically significant at all levels for females and

males, except for females who experienced only one form of maltreatment (see Table

5.4).

For males, models also control for region, parent occupation, parental quarrelling and fighting, emotional support, academic achievement, school punishment, and self-perception of health status. Considered attempting suicide Ten confounding variables including region, age, parental quarrelling and fighting,

emotional support, perceived parental relationship, school punishment, diagnosed

chronic disease and self-perception of health status, and body satisfaction were

142

entered in the model of the female sample. In the model for the male sample, eight

variables (religion, family economic status, parental quarrelling and fighting, parent

relationship, chronic disease, self-evaluation of health status and body satisfaction)

were controlled.

Suicidal thoughts of both males and females correlated with emotional maltreatment

(male: minor: OR = 1.20, more severe: OR = 2.11, female: minor: OR = 1.19, more

severe: OR = 2.78) and neglect (male: minor: OR = 1.11, more severe: OR = 2.98,

female: minor: OR = 1.83, more severe: OR = 2.93). However, statistical

significance was found only for neglect and more severe emotional maltreatment in

females and more severe neglect in males. Male respondents who experienced minor

physical maltreatment were significantly more likely to consider attempting suicide.

144

Dose-response relationship between considering attempting suicide and exposure to

multiple types of child maltreatment is shown in Figure 5.2. Female and male

participants exposed to two forms to four forms of maltreatment were significantly

more likely to have suicidal thoughts than non-exposed counterparts (see Table 5.5). Made a suicide plan After controlling for other variables that were significantly correlated with making a

suicide plan (in the bivariate analysis including religion, number of siblings, mother

and father occupation, parental quarrelling and fighting, quality of parent

relationship, chronic disease, health status, body satisfaction and school punishment

for the female models, and religion, family economic status, parental quarrelling and

fighting, quality of parent relationship, health status and school punishment for male

models) only child emotional maltreatment significantly predicted suicide plan

behaviour for both female and male participants (see Table 5.6).

Regarding multiple forms of child maltreatment, similar to suicidal thoughts, Figure

5.3 clearly shows that the more respondents were exposed to co-occurrence of

maltreatment, the more they reported making suicide plan. Participants exposed to

four forms of child maltreatment were more than nine times for females, and eight

times for males more likely than non maltreatment counterparts to make a specific

suicide plan.

Smoked in the past 30 days As mentioned earlier, due to the small number (n = 20) of female respondents who

reported that they had smoked during the past 30 days, multivariate logistic

regression therefore was performed only for males. Results, controlling for age,

family economic status, parental quarrelling and physical fighting, parental

relationship, source of emotional support, perception of health status, school

punishment experience, and academic achievement, are presented in Table 5.7. Male

smoking behaviour was significantly predicted by emotional maltreatment (minor:

OR = 2.18, more severe: OR = 2.33) and more severe sexual abuse (OR = 3.29). Co-

occurrence of child maltreatment was a statistically significant correlate of smoking

cigarettes.

Drinking alcohol among females was significantly predicted by minor emotional

maltreatment (OR = 1.94), minor physical maltreatment (OR = 1.91) and more

severe sexual abuse (OR = 4.28) when adjusted for the effect of region, age, religion,

family economic status, mother and father’s education and occupation, parental

quarrelling and fighting, emotional support, body satisfaction, and school

punishment. More severe emotional maltreatment (OR = 2.09), minor (OR = 1.77)

and more severe (OR = 3.02) sexual abuse significantly predicted male drinking

behaviour when controlling for age, region, family economic status, mother and

father education and occupation, body satisfaction, self-perception of health status,

and school punishment.

Experiencing co-occurrence of child maltreatment was significantly associated with

drinking alcohol among both females and males. However, the correlations were

stronger among females (see Table 5.8).

Had ever been drunk

Being exposed to more severe emotional maltreatment (OR = 2.1), sexual abuse

(minor: OR = 1.69, more severe: OR = 3.04) and multiple forms of child

maltreatment was significantly associated with higher risk of having ever been drunk

among male respondents when the effect of various confounding variables including

age, parental fighting and quarrelling, parental relationship, emotional help, chronic

disease, self-evaluation of health status, body satisfaction, and school punishment,

were controlled.

For female participants, however, after adjusting for age, family economic status,

mother and father’s education, father’s occupation, source of emotional support,

school punishment and repeated class only more severe sexual abuse (OR = 4.06)

and experience of four forms (OR = 3.44) of maltreatment significantly increase the

risk of ever being drunk (see Table 5.9)

Injured while drunk Very few females reported ever being injured while drunk. Sufficient male

respondents (n = 56) reported that they were injured while drunk to perform

multivariate logistic regression analysis. Age, religion, father’s education and

occupation, parental quarrelling and physically fighting, school punishment, and self-

perception of health status were entered first to the sequential logistic regression

models to explore the extent to which child maltreatment impacted on exposure to

injury while drunk among the male sample.

Table 5.10 summarizes the results of the models. No individual maltreatment types

significantly predicted injured while drunk among male participants, only those who

151

reported experiencing four forms of maltreatment were significantly more likely to

be accidentally injured while drunk (OR = 4.80).

Did not eat in 24 hours to lose weight This analysis was conducted for the female sample only due to the relatively small

number of male participants (n = 29) who reported this behaviour. Even though the

odds ratios increased when participants experienced each form of maltreatment or

co-occurrence of maltreatment, only the co-occurrence of child maltreatment was

significantly related to eating disorder behaviour among female students (two forms:

OR = 4.78, four forms: OR = 9.80) when adjusted for father’s occupation, perceived

parental relationship, body satisfaction, chronic disease, and academic results.

For the behaviour of carrying a weapon, the analysis was performed only with the

male sample because of the same reason given above. After controlling for family

economic status, parental quarrelling and fighting, perceived parental relationship,

source of emotional support, self-perception of health status and school punishment,

more severe emotional maltreatment (OR = 4.07) and severe sexual abuse (OR =

4.09) were significantly associated with carrying a weapon among male participants.

Co-occurrence of child maltreatment also clearly increased the risk of taking this

behaviour.

Threatened or injured by somebody with weapon on school setting

Child maltreatment appears to have more impact on being threatened or injured by

somebody with a weapon in a school setting among male than female respondents.

When controlled for family arrangement, parental quarrelling and fighting, parent

relationship, self-perception of health status, and school punishment, male

participants who experienced severe emotional maltreatment (OR = 3.01), minor

physical maltreatment (OR = 1.86), minor sexual abuse (OR = 2.43) and co-

occurrence of child maltreatment were significantly more likely to be threatened and

155

injured in school property. While for female respondents, exposure to emotional

maltreatment (minor: OR = 2.70, more severe: OR = 3.51), severe physical

maltreatment (OR = 3.06), and three forms of child maltreatment (OR = 4.09)

significantly increased the risk of being threatened and injured at school, adjusted for

age, religion, parental fighting, academic result, and school punishment.

Involved in physical fights Male participants who reported experiencing emotional maltreatment (minor: OR =

1.69, more severe: OR = 2.04), minor physical maltreatment (OR = 1.54), and minor

sexual abuse (OR = 1.76) were significantly more likely to be involved in fighting

when age, religion, family economics, family arrangement, parent quarrel and

fighting, parent relationship, body satisfaction, academic results, and school

punishment were controlled. In contrast, a history of neglect (minor: OR = 2.19,

more severe: OR =2.56) as well as minor sexual abuse (OR = 2.19) significantly

increased the risk of being involved in physical fights among the female sample after

taking into account the effect of various variables (religion, family economic status,

mothers and fathers occupation, parental quarrelling, fighting and drug problems,

emotional support, health status, and school punishment experience).

The dose-response rate of concomitance of child maltreatment is presented in Figure

5.4. Multiple forms of child maltreatment were significantly associated with being

involved in physical fights for both female and male participants. The impact,

however, was much stronger among female (four forms: OR = 9.88) than among

male respondents (four forms: OR = 4.67).

There were statistically significant gender differences in all health risk behaviours

examined. The rates of taking most health risk behaviours in this examined list

among urban and rural adolescents were not statistically different, except that

adolescents in urban area were more likely to consider attempting suicide, to smoke

cigarettes, and to drink alcohol. Regarding age groups, older students were

significantly more likely to report feeling sad and hopeless, smoking, drinking, and

being drunk during their lifetime.

159

160

Many significant correlates between each type of maltreatment, each level of

maltreatment co-occurrence and each health risk behaviour, were found after

controlling for a wide range of potential confounding variables (see summary Table

5.15). In general, the relationship pattern between child maltreatment and health risk

behaviours was similar for the female and male samples. Emotional maltreatment

significantly correlated to most of the behaviours examined. Physical maltreatment

seems to be more likely associated with being involved in physical fights and being

threatened. Sexual abuse was significantly related to smoking, drinking, being drunk,

and involvement in fighting. Statistically significant associations between neglect

and intentional injuries (involved in fighting, felt sad and hopeless, suicide attempts

and plans) were found.

Clearly, co-occurrence of child maltreatment was significantly associated with

almost all examined health risk behaviours. And dose response trend was observed in

most of the cases.

Chapter 6: Associations between Child Maltreatment and Mental and

Physical Health

Chapter 5 explored the possible impact of each type of child maltreatment and co-

occurrence of child maltreatment on a wide range of health risk behaviours,

controlling for a number of confounding variables among female and male

participants. The findings indicate that maltreatment victims appear to be

significantly more likely to take health risks. This is may be one of the pathways

leading to the impact of child maltreatment on physical and mental health of

maltreatment survivors. The main questions to be addressed in Chapter 6 are:

• What do background factors predict mental and physical health of the

adolescents?

• Do the effects of self-reported history of child maltreatment on mental and

physical health vary by the type of maltreatment, including emotional

maltreatment, physical maltreatment, sexual abuse and neglect?

• To what extent is the co-occurrence of childhood maltreatment experiences

associated with mental and physical health?

Before conducting the analyses in this chapter, evaluation of assumptions was

performed. The results led to transformation of several variables to reduce skewness,

the number of outliers, and improve the normality and linearity of the following

scales: four scales measuring child maltreatment (emotional, physical maltreatment,

sexual abuse, and neglect), two scales measuring mental health (depression and

anxiety). Logarithmic transformations were used on all these scales.

162

6.1 Descriptive analyses

Mental and physical health was measured using four scales assessing depression

(CES-D), anxiety, self-esteem (RSES), and physical health. For the depression and

anxiety scales, a higher score means more severe symptoms of these mental health

problems. With the self-esteem scale, a higher score indicates higher self-esteem. For

the physical health scale a higher physical health score means poorer general

physical health. These scales were tested and validated in the pilot study presented in

Chapter 3.

The reliability in terms of internal consistency of these scales in the main survey was

somewhat the same as the results in the pilot study, with Cronbach’s Alpha

coefficients ranging from .73 to .85. Cronbach’s Alpha values of these scales

together with means and standard deviation are presented in Table 6.1 below:

Preliminary examination of the levels of depression, anxiety, self-esteem, and

physical health, including comparisons by gender, region and age groups using

independent-sample t-tests were performed. The results are summarized in Table 6.2.

Independent t-tests revealed that there were significant differences in mean scores of

all four variables between males and females. This means that females were more

163

likely to be physically weaker than males, had lower self-esteem and more

depression and anxiety. However, as we can see from Table 6.2, the effects were

small, except for anxiety (eta squared = .10).

Table 6.3 summarizes the means and standard deviations of physical health, self-

esteem, depression and anxiety scales reported by adolescent participants according

to rural (Chilinh) and urban (Dongda) areas. Urban adolescents had significantly

higher self-esteem, less depression and anxiety than their rural counterparts.

However, the differences in the means were very small (eta squared = .01)

T-tests were also performed to compare the means of the four scales according to age

groups. For ease of description and in accordance with adolescent age groups

attending secondary and high schools, participants’ age was divided into two groups,

including 12-15 years equivalent to students studying at lower secondary school and

16-18 years equivalent to students studying at upper secondary school.

Older adolescents reported being significantly less physically healthy, and having

less self-esteem, and more anxiety than younger adolescents. Again, the effect sizes,

however, were small (eta squared = .002-.01) (see Table 6.4)

6.2 Bivariate correlations of child maltreatment with mental and physical health

The analyses were stratified into female and male. Correlation matrices of four

variables measuring emotional maltreatment, physical maltreatment, sexual abuse

and neglect and the four measures of physical health, depression, anxiety, and self-

esteem for females and males are presented in Table 6.5 and Table 6.6 respectively.

Emotional abuse was associated strongly with physical maltreatment and neglect in

both females (physical maltreatment: r = .51, neglect: r = .59) and males (physical

165

maltreatment: r = .52, neglect: r = .56). These results indicate the fact that each type

of child maltreatment was significantly related to each of the other maltreatment

domains. This finding is consistent with other studies examining multiple forms of

childhood maltreatment experiences (Higgins & McCabe, 2001a; Ney, Fung, &

Wickett, 1994; Turner et al., 2006). As can be seen from Tables 6.5 and 6.6, all four

health measures were also correlated with each other as expected; for example,

depression symptoms were positively associated with anxiety and poor physical

health and negatively with self-esteem. These results provide additional evidence on

the quality of maltreatment scales and health outcome measures used in this study.

The results of bivariate correlations clearly show that all four forms of child

maltreatment were significantly related to depression, anxiety, self-esteem, and

physical health, at the level of p<.001, among female and male adolescents alike. For

female participants, however, emotional maltreatment correlated strongest with all

four variables measuring health outcomes compared with physical maltreatment,

sexual abuse and neglect. A similar pattern was also observed among male

respondents.

6.3 Impact of co-occurrence exposure to child maltreatment

Two-way between groups analyses of variance were conducted to explore the impact

of co-occurrence of various forms of child maltreatment and age on physical and

mental health and to examine whether age moderated the relationship between

multiple forms of child maltreatment and health for female and male respondents.

Respondents were divided into 5 groups by level of exposure to child maltreatment

(coding ranges from 0 to 4 with 0 equal to no maltreatment; 1: one type of

maltreatment; 2: two types of maltreatment; 3: three types of maltreatment; and 4:

four forms of maltreatment), and two groups according to their age (12-15 years and

16-18 years).

The main effects of multiple maltreatment and age and the interaction effects on

depression, anxiety, self-esteem and physical health of female and male are

summarized in Table 6.7.

There were statistically significant main effects of co-occurrence of child

maltreatment on all four health outcome measures (depression, anxiety, self-esteem

and physical health) for both females and males at the level of p< .001. The effect

size of multiple maltreatment on depression for both female and male samples was

high (eta squared = .17 for female and .19 for male). Moderate effect sizes were

observed with anxiety (eta squared = .10 for female and male alike), self-esteem (eta

squared = .08 for female and .09 for male), and physical health (eta squared = .08 for

female and .06 for male).

The main effects of age and interaction effects on health outcomes did not reach

statistical significance or, if significant (effect of age on self-esteem for males and

physical health for males and females as well as effect of interaction on self-esteem

for females), the effect sizes were very small, from nearly zero to only .01.

168

Figures 6.1; 6.2; 6.3 and 6.4 illustrate the effect of exposure to concomitance of

various types of child maltreatment on four measures of health outcomes. Mean

scores of depression, anxiety, self-esteem and physical health are compared across

groups of participants with different levels of maltreatment exposure (non-

maltreatment to exposure to four types of maltreatment) by gender and two age

groups.

It is clear in each graph from Figures 6.1; 6.2; 6.3; and 6.4 that there were strong

associations between number of maltreatment forms experienced and the increase in

symptoms of depression, anxiety, poor physical health and the decrease of self-

esteem for both females and males and in the two age groups. Detailed figures of

mean scores of four health outcome measures by levels of maltreatment experience,

gender and age groups are summarized in Appendix 11.

Post-hoc comparison of mean levels of depression, anxiety, self-esteem, and physical

health across groups with various levels of maltreatment exposure for female and

male participants according to two age groups using the Tukey HSD test was

performed. The significant matrix across maltreatment levels for four health outcome

measures is presented in Table 6.8. With a few exceptions, comparisons across

number of child maltreatment forms showed statistically significant mean differences

(p<.05) in all health outcome measures.

6.4 Relative influence of each type of child maltreatment

To examine the relative influence of child emotional maltreatment, child physical

maltreatment, child sexual abuse, and neglect on each of four health outcome

measures including depression, anxiety, self-esteem, and physical health of

adolescent students, eight sequential multiple regression models were performed for

175

176

both female and male samples. For the first step of each equation, background

variables including demographic variables, family characteristics, child

characteristics (see Table 6.9) were entered in a block. Four child maltreatment

variables were entered as a block on step 2. Results of eight multiple regression

models are displayed in Table 6.9, including the unstandardized regression

coefficients (B), the standardized regression coefficients (β), t-test, R2 change, F

change, and adjusted R2 after entry of all independent variables.

For predicting the impacts on depression, the presence of four types of child

maltreatment significantly increases the amount of explained variance by 7% for

females and 8.8% for males. Emotional maltreatment and neglect were significantly

predictors for both female and male adolescents (p<.001). Region, emotional

support, self-perception of health status and academic achievement for males and

region, father’s occupation, body satisfaction, emotional support, and academic

achievement for females among the back ground variables, significantly survived as

predictors of depression in female and male respondents. The overall models were

significant, explaining 28% [F(26, 995) = 14.62, p <.001] for males and 26 % [F(26,

1,069) = 15.44, p <.001] for females.

Regarding the influence of child maltreatment on anxiety, child maltreatment

significantly explained about 6% of anxiety variance in females and males. Again,

emotional maltreatment and neglect significantly predicted anxiety for males.

However, for females, significant child maltreatment predictors were physical and

emotional maltreatment. Among the back ground variables, region, self-perception of

health status, chronic disease, body satisfaction, and parental quarrelling were

significantly associated with male anxiety, whereas region, age, father’s occupation,

self-perception of health status, chronic disease, and body satisfaction significantly

correlated with female anxiety. The final models significantly explained 22% [F(26,

995) = 11.84, p <.001] of anxiety in males and 21% [F(26, 1,069) = 11.85, p <.001]

in females.

The presence of four types of child maltreatment in the equations predicting self-

esteem also significantly contributed to explaining variance of self-esteem among

females (5%) and males (4.4%). Emotional maltreatment again was a significant

predictor for both females and males. Many background variables were significant

predictors of self-esteem for females, including region, perceived parental

relationship, body satisfaction, self-perception of health status, academic

achievement, and school punishment. For males, apart from predictors listed for

females, mother’s education and emotional support also significantly explained the

variance of self-esteem. In total, the models explained 23% [F(26, 995) = 12.89, p

<.001] of self-esteem variance for males and 28% [F(26, 1,069) = 15.19, p <.001] of

variance for females.

Finally, the variance of the physical health measure was also significant explained by

the multiple regression models. For males it explained 19% [F(26, 995) = 9.98, p

<.001] of the variance and 28% [F(26, 1,069) = 7.88, p <.001] of the variance for

females. However, four types of child maltreatment only contributed to significantly

explaining less than 5% of the variance in each model. Emotional maltreatment

significantly influenced male physical health whereas emotional and physical

maltreatment significantly predicted physical health of female adolescents.

Background variables that significantly predicted male physical health were region,

religion, parental quarrelling, chronic disease, and self-perception of health status.

For female physical health, the variables were religion, chronic disease, and self-

perception of health status.

6.5 Summary

This chapter has examined the impact of child maltreatment including each

individual type and multiple types on health outcome measures including depression,

anxiety, self-esteem and general physical health. In bivariate correlation analyses,

each type of child maltreatment was significantly associated with each health

outcome measure. However, correlations between emotional maltreatment and health

were higher than for the other three forms of maltreatment. All types of child

183

maltreatment appeared to correlate more highly with depression than the other health

outcomes.

Regarding co-occurrence of maltreatment, the results presented in this chapter

suggest that cumulative exposure to multiple forms of child maltreatment represents

a substantial risk for adolescent health, especially mental health (depression and

anxiety).

In multiple regression analyses, after controlling for a wide range of background

variables, the presence of four types of child maltreatment significantly explained the

variance (between 5% to 9%) of adolescent health status. Emotional maltreatment

and neglect appeared to be the strongest influences on mental and physical health of

adolescents.

Chapter 7: Discussion

This study reports on the prevalence and co-occurrence of four forms of child

maltreatment and examines associations with demographic factors, family

characteristics and family environment in a school-based Vietnamese adolescent

sample. Furthermore, the possible effects of child maltreatment on a wide range of

health risk behaviours and physical and mental health were examined. To the best of

our knowledge this study is the most comprehensive of this kind to be conducted in

Vietnam and is one of the first such studies in Asia.

Unlike most previous studies conducted in different parts of the world, this study

simultaneously focused on all main forms of child maltreatment. As a result, it was

able to estimate not only the prevalence of each form of child maltreatment but also

the prevalence of co-occurring types of maltreatment including those forms that have

seldom been studied in earlier research (i.e. emotional maltreatment and neglect).

Moreover, we adjusted for the effects of a wide range of possible confounding

factors including demographic characteristics, family structure and environment

variables when examining the correlations between child maltreatment and health

outcomes. This study has generated a number of valuable findings, both for

improving knowledge of child maltreatment in Vietnam, and for broader research

into the consequences of maltreatment.

7.1 The prevalence of child maltreatment and correlates with background variables

An important limitation of existing research worldwide is that many studies use

measures and survey methods that are not directly comparable (Fergusson & Mullen,

1999). Consequently, it is difficult to make an accurate comparison of child

maltreatment prevalence between studies. However, there is sufficient international

data available to establish the probable ranges of prevalence of different forms of

child maltreatment. Findings from this study are broadly consistent with previous

185

studies in that child maltreatment is found to be a widespread phenomenon wherever

it is measured (Fergusson & Mullen, 1999).

The prevalence of child physical maltreatment in Vietnam appears to be lower

compared with several other studies in developing countries. Nearly fifty per cent

(47.5%) of respondents in this study reported lifetime physical maltreatment

experiences and boys (54.1%) were more likely to be maltreated than girls (41.0%).

Kim and colleagues (2000) reported higher physical prevalence in the Chinese and

Korean school student sample. During the last 12 months 70.6% of children in China

and 68.9% of children in Korea experienced physical violence in the family.

Additionally, severe physical maltreatment was more predominant in China (22.6%)

and especially in Korea (51.2%) compared to Vietnam (9.0%). Egyptian study

(Youssef et al., 1998a, , 1998b) also revealed a higher prevalence of physical

maltreatment than that of present study in Vietnam. During the school year, 72.8% of

Egyptian adolescents reported physical maltreatment by teachers and 37.5% by

parents.

Furthermore, the proportion of adolescents who required medical consultations as a

result of injuries incurred by physical maltreatment was also higher in Egypt (21.9%

and 22.8% due to physical maltreatment by teachers and parents respectively)

compared to our study (14.9% due to physically maltreated by any adult). It is also

very important to note that our study retrospectively asked about life time physical

maltreatment by any adult while the study in Egypt asked about physical

maltreatment during one scholastic year and only abuse by parents and teachers. It

therefore may be assumed that the lifetime prevalence of physical maltreatment

among adolescents in Egypt would be much higher than the annual incidence rates

estimated in that study.

However, the rate of adolescents who experienced physical maltreatment and the

proportion of adolescents injured from physical maltreatment in our study was higher

than that of recent studies conducted among Hong Kong adolescents. Authors (Lau et

al., 2003; Lau et al., 2005) found more than four per cent adolescents physically

186

maltreated during the last 6 months and 10.4% ever injured and 2.9% injured in the

past 6 months from beating occurring without provocation by family members).

Again, differences in definition of perpetrators and time frame which were broader in

the current study than in Hong Kong studies might explain some of the differences in

physical maltreatment prevalence and the proportion of adolescents injured due to

this violence.

The prevalence of physical maltreatment in Vietnam in comparison with several

other studies conducted in European and Western countries appeared to be higher.

However, those studies all used narrower definitions of child physical maltreatment

(May-Chahal & Cawson, 2005; Meston et al., 1999; Moran et al., 2004; Sebre et al.,

2004). Nevertheless, regarding the prevalence of physical maltreatment among boys

and girls, our finding was consistent with most previous studies that find males are

more likely to report having physically maltreatment experiences than females

regardless of the discrepancies in definitions.

Little research into child maltreatment has been done in Vietnam and most child

maltreatment research has focused mainly on physical punishment. Most local

information is derived from studies by NGOs, and do not have clear description of

study methodology and definition of maltreatment. Therefore it is impossible to

make an accurate comparison of our findings with previous Vietnamese data.

Nevertheless, just recently there have been two reports issued by UNICEF

(Michaelson, 2004) and Save the Children Sweden in Vietnam (PFCSI & SCS,

2005). These reports revealed preliminary information regarding some forms of child

maltreatment, which is similar to that of the present study. The estimated physical

maltreatment prevalence from these reports ranging from nearly forty to just above

fifty per cent of adolescents reported that they had been physically punished with an

implement in their life time and boys were significantly more likely than girls to

report this adverse experience. Similar to the survey conducted by the Vietnam

Population, Family and Children Scientific Institute and Save the Children Sweden

(PFCSI & SCS, 2005) our study also revealed that the father was the most common

perpetrator of physical maltreatment.

187

Internationally, there have been quite a few community and school-based surveys

aimed at determining the life time prevalence of childhood sexual abuse. As

indicated in the Appendix 1 child sexual abuse prevalence among adolescents and

early adulthood varies considerably from nearly two per cent in the US (Smith et al.,

2005) up to over fifty per cent in South Africa (Madu & Peltzer, 2000) depending on

the definition of study, the number and wording of the questions used to estimate

prevalence, and also of course on the cultural differences of the study context. In

Vietnam, estimated prevalence of any type of sexual abuse of 19.7% in the whole

sample falls in the middle of the range of international findings. It is comparable to

the recent study conducted with a representative sample of young people in the

United Kingdom used a similar broad definition including non-contact and contact

sexually adverse events (16.0%) (May-Chahal & Cawson, 2005).

Also using broad definition of child sexual abuse, findings from Vietnam’s

neighbouring country, China were slightly lower; 13.6% of Chinese school

adolescents reported any unwanted sexual experiences before age of 16 (Chen,

Dunne et al., 2004), than our estimated prevalence (19.7%). It is important to note

that child sexual abuse case defined by our study was somewhat different from the

definition used in the study in China in terms of timeframe and the number of

adverse sexual events experienced by the respondents. It is therefore difficult to

assess whether the findings reflect the true difference or whether there was a

discrepancy in defining abuse cases.

The proportion of participants in our study who reported experience of attempted

rape and rape were 3.2% and 2.7% respectively, which also falls in the lower range

of internationally estimated rates (see Appendix 1) from about two per cent to more

than eight per cent for attempted rape and from nearly one per cent to six per cent of

actual rape (Chen, Dunne et al., 2004; Choquet, Darves-Bornoz, Ledoux, Manfredi,

& Hassler, 1997; King et al., 2004). These findings are very similar to recent studies

among adolescents in China (Chen et al., 2006; Chen & Dunne, 2006). In the report

of UNICEF, Vietnam, the only community based information of sexual abuse in

Vietnam available so far, Michaelson (2004) estimated that 2.7% of adolescents

188

reported having been raped or experiencing other forms of sexual assault as a child.

Unfortunately, the report did not provide in details what sexual assault means in this

survey. In this regard, we therefore could not make further discussion.

The results of our study indicated that sexual abuse is usually perpetrated by

someone known by the victims and predominantly by male perpetrators. These

findings replicate national (Michaelson, 2004; SIDA, 2000) and international

findings (Finkelhor, 1994).

Interestingly, unlike most studies where girls are more likely to report having adverse

sexual experiences than boys, our study found that more boys (21.8%) than girls

(18.4%) met the criteria of exposure to sexual abuse. This finding is similar to the

pattern found in other studies on sexual maltreatment in Jewish and Arab schools in

Israel (Benbenishty et al., 2002; Zeira et al., 2002) and in accordance with results of

Michaelson’s study in Vietnam (Michaelson, 2004), in which males were twice as

likely to report experience of unsafe touching of private parts while growing up or

being raped as a child, than were females.

It would be premature to conclude that the actual incidence of sexual abuse of female

children is lower in Vietnam. There is a need for more research, especially because

the pattern in Vietnam and a few other countries is strikingly different from the

majority of research in western countries. There are several possible explanations.

The lower rate of sexual abuse among girls in the first two community based studies

in Vietnam may be a reflection of the residual attitudes of shame associated with

reporting sexual abuse (SIDA, 2000). Shame feelings seems to be more predominant

among females than males because of the cultural values where the power

differences between males and females in Asia make it difficult for females to

reported “shameful” adverse experiences, especially when the perpetrator is a man

known within the family or community (Futa, Hsu, & Hansen, 2001). This

contention is supported by the apparent reluctance of adult females to report having

experienced sexual abuse when compared with higher rates reported by adult males

and female children (Michaelson, 2004). Another possibility related to cultural

189

norms is that fondling the private part of young boys is considered as a common

cultural practice of adult male relatives in Vietnam. While many adults perceive that

the practice is a harmless expression of adult affection, many boys report that they

consider it as intrusive or even abusive (Michaelson, 2004).

There are similarities and differences in our findings concerning child sexual abuse

in Vietnam compared with patterns found in international studies. Overall, though,

our data clearly indicate that Vietnamese children are just as vulnerable to sexual

abuse as are children living in many other parts of the world.

Relatively little is known about the extent of child emotional maltreatment and

neglect worldwide. This study is among the first to report prevalence of emotional

maltreatment (39.5%) and neglect (29.3%) among young people in Vietnam. Again,

our results fall within the range of the findings from international studies that

estimate the prevalence of emotional maltreatment and neglect among community-

based adolescent and early adult samples (see Appendix 1). Females in our study

were more likely to report experiences of emotional maltreatment and neglect than

were males. This pattern was similar to studies conducted in the UK (May-Chahal &

Cawson, 2005), Turkey (Zoroglu et al., 2003), and Japan (Yamamoto et al., 1999)

but contrary to the findings from studies in Iran (Stephenson et al., 2006), Israel

(Benbenishty et al., 2002), and Canada (Meston et al., 1999). More comprehensive

studies are needed before we can determine whether there is a universal gender

difference in incidence of emotional maltreatment and neglect, or true variation

across cultures.

The prevalence of child emotional maltreatment in our study was somewhat

consistent to the findings from two recent studies in Vietnam where children aged

from 6 to 18 years old reported that they were shouted at (65.2%) and humiliated,

insulted (30.9%) by adults when they had made a mistake (PFCSI & SCS, 2005) and

35.7% adolescents in another study reported having experienced verbal or emotional

maltreatment (Michaelson, 2004). It is impossible to make a comparison of neglect

prevalence due to the fact that there are no figures available on neglect in Vietnam.

190

Michaelson’s (2004) qualitative study in Vietnam indicated that emotional neglect

and educational neglect may be common and serious forms of neglect in Vietnam.

Most participants in Michaelson’s study appear to clearly separate the unavoidable

effects of living in poverty from the concept of child neglect. During qualitative

interviews for the pilot phase of this research, we interviewed 4 teachers, 4 parents

and 8 students (see Chapter 3 and Appendix 8). The qualitative interviews of our

research revealed that emotional neglect is an emerging problem that may be

independent of the poverty issue and needs to be addressed. This is indicated in the

accounts of two teachers below.

A common type of child maltreatment now is lack of care for children in the

broader sense that is not only lack of care for materials but now many families

in cities can earn a lot of money and give money to children and they incorrectly

think that is enough. It really creates a new social problem. (Female teacher,

Hanoi)

Child maltreatment is understood that now many families do not treat children

well, for example not supporting children studying, parents travelling for doing

business and leaving children with their relatives. In Chilinh now increasing

numbers of parents are working abroad; their children have to stay at home and

those children are at risk of maltreatment. (Female teacher, Chilinh)

It is evident that maltreatment types do not occur independently. Rather, a significant

proportion of maltreated individuals experience not just multiple events of one type

of maltreatment but they also are likely to be exposed to other maltreatment forms.

Multiple-type maltreatment refers to the co-occurrence of more than one form of

child maltreatment, commonly including sexual abuse, physical and emotional

maltreatment and neglect, some researchers also mention witnessing violence as

another type of child maltreatment (Clemmons et al., 2003; Higgins & McCabe,

191

2001b). From the literature review, it is clear that the empirical knowledge base of

the coexistence of various maltreatment types is limited. This study is among the

first in Asia to estimate the extent to which the concomitance of different types of

child maltreatment was reported by a community-based adolescent sample.

The present research extends findings from a few previous studies on poly-

victimization maltreatment in Western countries (Clemmons et al., 2003; Higgins &

McCabe, 2000a; Scher et al., 2004) to an Asian country. We found that Vietnamese

adolescents may also commonly experience multiple forms of child maltreatment. In

this study, more than forty per cent (41.5%) of participants reported being subjected

to two or more forms of child maltreatment, of which 20.7%, 14.5% and 6.3%

experienced 2 forms, 3 forms and 4 forms respectively. These results are relatively

similar to the findings from a community-based adult sample in Australia (Higgins &

McCabe, 2000a). In his study, Higgins examined the co-occurrence of five forms of

child victimization (sexual, physical, emotional maltreatment, neglect and witnessing

family violence). He found that 43.4% of respondents reported experiencing two or

more forms of maltreatment with 15.4%, 11.4%, 9.7%, and 6.9% experienced two,

three, four, or five forms respectively. However, our estimated prevalence of poly

victimization maltreatment seems to be higher than Scher’s estimate (2004) in

America with 13.5% of an adult sample exposed to two or more forms of child

maltreatment. Our findings are also much higher than that reported in the only study

available from a non-western country, Turkey, where 8.7%, 3.8%, and 1.3% of the

school adolescents reported having experienced of two, three, and four forms of

maltreatment respectively (Zoroglu et al., 2003). The differences of definition of

maltreatment cases used in these studies may be among the potential factors to

contribute to the differences in the findings.

In this study, the most common co-occurrence of two forms of maltreatment was

emotional and physical maltreatment (8.3%), and of three forms of maltreatment was

emotional, physical maltreatment and neglect (8.9%). This pattern of concomitance

of child maltreatment corroborates those of earlier research conducted among an

adult community sample in the USA that also reported emotional abuse and physical

192

abuse as the most common combination of child maltreatment types (8.3% of the

overall sample) (Scher et al., 2004).

While the multiple type maltreatment rates may be somewhat different between

studies, the conclusion from our findings supports that of earlier research, that co-

occurrence of various forms of child maltreatment is not uncommon. This finding

strongly suggests that studying individual types of child maltreatment in isolation

from other types may not capture a comprehensive picture of the problem.

The present study examined the correlates of a wide range of background variables

which consist of demographic characteristics, family characteristics and family

environment, for each of the four forms of child maltreatment. This study examined

key variables in two level of the ecological model including individual and family

levels and one variable belonging to community level (urban and rural region).

Generally speaking, findings are congruent with the ecological model (see Figure 2.1

in Chapter 2) with risk factors of child maltreatment embedded in different layers

from individual to relationships, community and society (Belsky, 1993). The

significant predictors of each form of child maltreatment varied considerably. The

key risk factors for reporting child maltreatment experience in this study were

individual factors (gender, age, parent marital status, family arrangement),

relationship factors (parental quarrelling and fighting, perceived parental

relationship, and source of support), and community factors (urban and rural areas)

when adjusted for other factors. The only factors that emerged as strongly

significantly associated with all maltreatment types examined were relationship

factors: quality of parent relationship and source of support to whom children can

turn when they need help.

The finding that witnessing verbal and physical violence between parents and poor

quality parental relationship significantly increased the risk of all four forms of

maltreatment is consistent with the results from numerous studies conducted in the

West (Black, Heyman et al., 2001a; Black, Heyman, & Smith Slep, 2001b; Black,

Smith Slep et al., 2001; Schumacher et al., 2001) and with a recent study in a

193

developing country (Stephenson et al., 2006). The present study also found that in

comparison to children who ask for support from members of the family including

mother, father, or siblings when they need help, those who did not seek help from

those family members were significantly more likely to report maltreatment

experiences. However, this factor by itself may not cause the maltreatment rather it

might reflect the poor parenting style, poor parental attachment and poor relationship

among family members, which may have a causal relationship with maltreatment.

Parental drug and alcohol problems and social demographic characteristics often are

found to be significantly associated with child maltreatment (Black, Heyman et al.,

2001a; Black, Heyman et al., 2001b; Black, Smith Slep et al., 2001; Fergusson &

Lynskey, 1997; Fergusson & Mullen, 1999; Finkelhor & Baron, 1986; Schumacher

et al., 2001; Sebre et al., 2004). Children who come from low income families, with

low parent education, unemployed mothers, and without one of the biological parents

at home were most at risk of being maltreated. However, these findings were not

replicated in our study. Family economic status did not predict any type of

maltreatment. Although parent education and occupation were marginally correlated

with maltreatment in bivariate analysis, both appeared to be insignificant after

controlling for the effects of other factors in multivariate logistic regression models,

excepting the association between mother’s unemployment and sexual abuse. These

findings do not mean that it reflects the actual fact in Vietnamese context, rather it

suggests that more studies need to be conducted to comprehensively examine the risk

factors of child maltreatment in Vietnam. Parental drug and alcohol problems also

were not significantly associated with maltreatment in multivariate analysis in this

study. However, power issue when using multivariate logistic regression could be the

main reason because we found only a small percentage [3.2% (81 respondents) for

overall sample] of participants who reported their parents had this problem. In

comparison to large-scale community-based studies in North America where parent

substance abuse was found as a significant predictor of child maltreatment when

using multivariate analysis, the prevalence of parental substance abuse was much

higher than our data (Chaffin et al., 1996; Walsh et al., 2003). In Canada, Walsh,

MacMillan, and Jamieson (2003) found that 17.2% of 8,359 respondents reported a

194

parental history of substance abuse. In a prospective community case-control study

in the US, Chaffin, Kelleher, and Hollenberg (1996) revealed that 5.7% of control

group and 15.1% of physical abuse respondents and 21.0% of neglect cases reported

parent substance abuse disorders.

7.2 Correlates of child maltreatment and health risk behaviours

Health risk behaviours in adolescence such as smoking, drinking, drug use, self-harm

and anti-social behaviours etc. are issues of major public health concern.

Researchers, mostly in the United States and other developed countries, and recently,

in a small number of developing countries, have begun documenting the prevalence

and risk and protective factors of a number of health risk behaviours (Anteghini et

al., 2001; Blum et al., 2003; Dowdell & Santucci, 2004; Sarigiani, Ryan, & Petersen,

1999; Zweig et al., 2001). History of being maltreated has been reported to increase

rates of various health risk behaviours in studies among Western adult samples

(Dube et al., 2006; Rodgers et al., 2004; Walker et al., 1999) and adolescent samples

(Bensley, Spieker et al., 1999; Bensley, Van Eenwyk, Spieker, & Schoder, 1999;

Chen et al., 2006; Chen, Dunne et al., 2004). However the degree of risk associated

with different types of maltreatment and cumulative effects of co-occurrence of

maltreatment are not well documented. Our study is among the first in Vietnam and

Asian countries to examine the relative and additive effects of four forms of child

maltreatment on a wide range of health risk behaviours.

Focusing first on the prevalence and gender differences in various health risk

behaviours, we found that prevalence is somewhat similar to results from other large

scale surveys conducted among school adolescents in Hong Kong, China and

Malaysia (Chen, Dunne et al., 2004; Chen, Lee, Wong, & Kaur, 2005; Lee & Tsang,

2004; Liu, Tein, Zhao, & Sandler, 2005). Boys appear to report more externalizing

harmful behaviours such as involvement in physical fights, carrying a weapon,

smoking, drinking, and being injured while drunk, whereas girls report more

internalizing health risk behaviours, for example, suicidal thoughts and attempts, and

195

dangerous dieting practices. However, the proportion of children with intentional

injury, smoking, drinking, and binge drinking in our study was much lower than in

the USA (Zweig et al., 2001), where also not many gender differences in these

behaviours was observed. This could be due to the fact that risk behaviours among

adolescents may be partially determined by culture (Ebin et al., 2001; Grunbaum et

al., 2000; Kaplan et al., 2003; Viner et al., 2006). Studies conducted among

adolescents in the UK and the USA have found that rates of smoking, drinking, and

other health compromising behaviours are lower among Asian American and Asian

British adolescents than Hispanic or Caucasian young people. In traditional Asian

cultures the individual is considered as part of the family and community. The

relationship between parent and child is hierarchical whereby children are expected

to follow the family rules and maintain family traditions. This traditional practice

may play a role in explaining the effect of health risk behaviours of Asian

adolescents (Bhattacharya, 1998).

There is little information on health related behaviours among adolescents available

in Vietnam to make comparison to the present study. The rate of participants in this

study reporting that they had carried a weapon (3.2%) was comparable with the

Survey Assessment of Vietnamese Youth (SAVY) (2.3%), which was conducted

from 2003-2005 and is the largest and most comprehensive survey ever among youth

in Vietnam (MOH, GSO, WHO, & UNICEF, 2005). The proportion of male

adolescents in our study who reported smoking behaviours (7.1%) was also relatively

similar to SAVY’s result of male rates of current smoking (9.8%). However, the

proportion of youths who reported suicidal thoughts in SAVY was much lower than

the finding from our study (3.4% versus 9.2%). We could not find any explanation

for that at the moment, however as SAVY’s report (MOH et al., 2005) notes that:

Some anecdotal evidence and hospital records suggest that suicide is a more

significant cause of [Vietnamese] youth mortality and morbidity than SAVY

suggests. It is important to understand further these self-harm and self-

196

destructive behaviours and thoughts, and consider what might be the

contributing factors. (p.71)

Problem behaviours in adolescence might be influenced by a variety of factors such

as peer pressure to perform behaviours not allowed by adults, disappointment in

relationships, or academic difficulties (Bensley, Van Eenwyk et al., 1999).

Furthermore, the literature review has also shown that a history of child maltreatment

is a contributing factor for engaging in behaviours that compromise health. The

findings of this study clearly showed the significant relationship between child

maltreatment and various health risk behaviours of adolescents when statistically

controlling for differences in the family social backgrounds, and other adolescent

characteristics. These findings are consistent with results of international studies such

as those by Bensley, Spieker et al.(1999); Bensley, Van Eenwyk et al.(1999); Chen,

Dunne et al. (2004); Hibbard et al. (1990); King et al (2004); Lau et al. (2005); and

Riggs et al. (1990).

In general, in this study child emotional and physical maltreatment, sexual abuse and

neglect had independent correlations with different health risk behaviours examined

for both female and male adolescents. There was a clear dose-response relationship

with frequencies of health risk behaviours increasing according to the levels of

maltreatment severity. Multivariate analysis showed that for both females and males

emotional maltreatment were significantly correlated with more behavioural

problems examined (see Table 5.15). However, sexual abuse seems to have a

particular effect on behavioural problems among males. Controlling for background

factors and co-occurring types of maltreatment, CSA was significantly associated

with smoking, drinking, being drunk, carrying a weapon, being threatened and

involving in fighting among male participants while only drinking, being drunk and

involvement in fighting remained significant among female respondents. This pattern

of gender difference in the impact of sexual abuse on behaviours of adolescents is in

accordance with studies among adolescents in the USA (Hibbard et al., 1990) and

China (Chen, Dunne et al., 2004). A question could be raised here as to why sexually

abused males exhibit more externalizing problematic behaviours. The differences in

197

socialization patterns and in the ways of expressing of psychological and emotional

problems might be among various possibilities. Further study is needed to address

this issue.

In current study physical maltreatment and neglect appear to have less robust

associations with behavioural problems, in comparison with emotional maltreatment

and sexual abuse. The relationship between physical maltreatment and adolescent

behaviours such as suicidal behaviours, smoking and drinking in our study was less

strong than results reported in studies in Hong Kong (Lau et al., 1999; Lau et al.,

2005) and the US (Bensley, Spieker et al., 1999; Riggs et al., 1990), in terms of the

values of odds ratios and statistical significance. There are several possible

explanations for the differences. First, the potential confounding factors such as

demographic characteristics, family factors and adolescent characteristics were not

taken into account (Lau et al., 1999) or that was less comprehensive adjustment

(Bensley, Spieker et al., 1999; Lau et al., 2005) compared to this study. Second, the

literature has shown that childhood maltreatment victims are more likely to have

multiple maltreatment experiences. Given the comorbidities that exist between

different types of child maltreatment, those previous studies, when examining the

relative association of one type of child maltreatment (physical maltreatment in this

case) had failed to control for effects of other types (Lau et al., 1999; Lau et al.,

2005) or only controlled for the effects of sexual abuse (Bensley, Spieker et al.,

1999; Riggs et al., 1990) but not emotional maltreatment and neglect, unlike this

Vietnamese study. Third, in controlling for quite a few confounding variables and the

effects of three other types of maltreatment, less statistical power might make it

impossible to detect significant relationships as in the other studies when they may

actually exist in our study in several models. Larger sample sizes are recommended

for future studies of this kind.

Neglect seems to have a strong influence on internalising behaviours such as feeling

sad and hopeless and considering suicide for both males and females in our study.

Zoroglu and colleagues (2003) had reported similar results that neglect had

significant association with suicide attempt and self-mutilation among adolescents in

198

Turkey. No other research has examined the effect of neglect with other health

compromising behaviours. Individually, each type of child maltreatment examined in

the present study appears to have its own pattern of relationships with a wide range

of health risk behaviours that would lead to the suggestion that these types of child

maltreatment in isolation, may contribute to certain health problems in adolescents.

Although much prior research has focused on the effects of unique forms of child

maltreatment such as sexual abuse or physical maltreatment, as different type of

maltreatment often coexist, focusing on the effect of just one type of maltreatment

may be misleading (McGee, Wolfe, Yuen, Wilson, & Carnochan, 1995). Recently,

several studies have identified the dose-response relationship of multiple types of

child maltreatment with various health related outcomes, mainly among adult

samples. A graded relationship between a number of adverse childhood experiences

and later risk of engagement in the number of health compromising behaviours such

as smoking, alcohol and drug use, obesity, and physical inactivity were found (Dube

et al., 2006; Felitti et al., 1998; Walker et al., 1999).

The present study revealed that nearly one third (31.5%) of all respondents reported

having experienced two or more childhood trauma types. We examined the additive

effects of multiple types of maltreatment. Consistent with previous research among

adult samples in Western countries, results of our study also strongly support the

hypothesis that an increase in the number of maltreatment types significantly

increased the risk of adolescents engaging in a wide range of health risk behaviours

when effects of various background variables were controlled. This pattern was

found for both females and males and in almost all the behaviours examined (see

Table 5.15). In particular, we found that exposure to three or four forms of child

maltreatment greatly increased the chance of suicidal thoughts and attempts,

involvement in physical fights (for both males and females) and disordered eating

behaviour (for females) with the odds ratios increasing up to nearly 10 compared

with non-maltreated participants. In studies among school adolescents in the USA,

results also revealed that much stronger associations were found between combined

abuse and molestation and alcohol/cigarette experimentation, marijuana use/regular

199

drinking, suicide thoughts and plan, non injurious and injurious suicide attempts

compared with non sexual abuse or molestation alone (Bensley, Spieker et al., 1999;

Bensley, Van Eenwyk et al., 1999) or between combined physical and sexual abuse

and substance use (tobacco, alcohol, and illicit drugs) (Moran et al., 2004). There is

a paucity of information about this issue in non-Western and developing countries.

The only available study among school based adolescents examining the additive

effects of four types of child maltreatment on suicide attempt, self-mutilation, and

dissociation was conducted in Turkey by Zoroglu et al. (2003). Their findings were

consistent with prior research.

Results of this study also indicated that there seem to be few cultural differences in

terms of effect of child maltreatment on health risk behaviours of adolescents. This

study replicated main findings from studies conducted in Western and other cultures.

First, certain health risk behaviours may strongly relate to specific types of child

maltreatment. Second, and more importantly, co-occurrence of different types of

child maltreatment had a strongly graded relationship with a wide range of health

compromising behaviours. The findings of concomitant effects on health risk

behaviours of Vietnamese adolescents from our study further suggest that it is

important for researchers in all cultures to examine a broader history of child

maltreatment experiences rather than trying to relate certain forms of maltreatment to

specific outcomes (Dong et al., 2003).

What might explain these phenomena? A review of possible theoretical mechanisms

which might mediate the relationship between child maltreatment experiences and

victims’ health risk behaviours suggested possible developmental pathways to

negative outcomes including chronic problems, behavioural and emotional disorders

(Wolfe, 1999). This theory proposes that child maltreatment together with various

factors such as family disadvantage set a lifelong pattern for poor relational

representations. This may lead to dysregulation of emotions and deficits in social

awareness and peer acceptance. These processes, in turn, influence adjustment

outcomes. Maltreated children, for example, may develop negative representational

models of themselves and others, changes in self-worth, and development of

200

maladaptive coping styles which further impairs their ability to regulate their

affective and behavioural responses (Bensley, Spieker et al., 1999; Wolfe, 1999).

Individuals with a history of maltreatment may be more likely to use avoidance

coping methods (Bal, Crombez, Van Oost, & De Bourdeaudhuij, 2003; Hiebert-

Murphy, 1998; Thabet, Tischler, & Vostanis, 2004) such as smoking, drinking and

drug use to deal with the abusive experiences, with expectancies that they obtain

possible relief and stress reduction.

For substance use in particular, there is an important question about whether the

association between child maltreatment and subsequent substance use reflects a

causal relationship. The answer for this question is still controversial. In a study of

substantiated cases of child maltreatment from 1967 to 1971, matched on sex, age,

race, and social class with non-maltreated children and followed prospectively into

early adulthood, Schuck and Widom (2001) suggested that childhood maltreatment

may be one of the causal factors in the development of alcohol problems in female

victims. In contrast, other studies found that child maltreatment is indirectly linked to

smoking and drinking and poly-substance use through a number of factors including

negative family support, poor social support, avoidance coping, negative mood state,

low self-esteem and avoidance belief (Hodson, 2002; Simons, 2001). Although

evidence indicating the direct causal relationship between child maltreatment and

problem behaviours of victims is controversial, a number of studies have supported

the proposed pathway mentioned above. Yet, given the complexity of child

maltreatment and its effects, there are still challenges in operationalizing and testing

the theory.

Nevertheless, the findings of the present study provide additional evidence to

indicate that there have been strong relative correlations between each form of child

maltreatment and additive associations between multiple types of child maltreatment

with a numbers of health risk behaviours among Asian population-based adolescents.

The increased risk of undertaking health compromising behaviours among maltreated

victims has been proposed as one of the best known possible pathways, namely

behaviour, social, cognitive, and emotional pathways, by which maltreatment

201

victimisation might influence health (Kendall-Tackett, 2002). The following section

will discuss findings from our study on the influence of maltreatment experiences on

the health of adolescents.

7.3 Correlates of child maltreatment and physical and mental health

Over the past decades, researchers have documented the higher frequency of many

health problems among maltreated individuals. The present study examined the

influence of childhood maltreatment experiences on self-reported general physical

health, depression, anxiety and self-esteem. Unlike most previous studies in this area,

we did not examine each type of child maltreatment in isolation; rather we

simultaneously focused on four forms of maltreatment experiences and took into

account the broader context that is likely to impact on health outcomes. Further

more, this study also examined the cumulative effects of experiencing multiple types

of child maltreatment on adolescent health. This is one of the pioneering studies in

Asian countries taking these approaches when looking at the possible health

consequences of child abuse.

As earlier studies indicated, that there was a high degree of overlap between different

forms of child maltreatment experiences. Prior to examining the influence of child

maltreatment on health outcomes, correlation between four maltreatment scales was

performed. In accordance with findings from Western countries (Bernstein et al.,

1994; Dong et al., 2004; Higgins & McCabe, 2000a; Turner et al., 2006) all

maltreatment measures were associated with each other. The strongest relationship

was found between emotional maltreatment and neglect, and physical maltreatment

for both males and females. These findings indicated that children who reported

being emotionally maltreated also are likely to be physically abused or neglected.

From the current data, it is clear that different forms of child maltreatment

experiences do not occur in isolation. Therefore our results support the argument that

202

a study which looks only at the effects of one form of maltreatment in isolation with

other forms might not be appropriate.

The bivariate correlations between all four types of maltreatment and each mental

health outcome measure from our study were consistent with previous studies (Bal,

Van Oost et al., 2003; Chen, Dunne et al., 2004; Haj-Yahia & Tamish, 2001;

Lansford et al., 2002; Oates, Forrest, & Peacock, 1985; Sebre et al., 2004). We also

found significant association between child maltreatment and general physical

health.

Stratification by age and gender the study results supported the hypothesis that some

adolescent health problems (specifically, depression, anxiety, self-esteem, and poor

general physical health) increased as reported experiences of the number of different

types of child maltreatment increased. This finding corroborates a small body of

previous research conducted in this area among adults (Duran et al., 2004; Higgins &

McCabe, 2000a; Walker et al., 1999) and children (Turner et al., 2006) in developed

nations. A wide range of health outcomes were examined in previous studies such as

self-esteem, dissociation, anxiety, depression, anger/aggression, sexual problem,

various physical health symptoms etc. In these studies victimization combinations

were found to be more traumatic and associated with more health problems than

single forms of victimization. The evidence of cumulative effects of co-occurrence of

various types of child maltreatment on health outcomes supports an additive model

of trauma (Fox & Gilbert, 1994).

Furthermore, results of the present study also showed that for all health outcomes,

the mean increased in a stepwise fashion for depression, anxiety and physical health

problems, and decreased stepwise for self-esteem from no maltreatment to two,

three, and four forms of childhood maltreatment. In most cases the pair-wise

comparisons were statistically significant. This finding indicates clearly the dose-

response pattern between cumulative lifetime maltreatment types and health

consequences, when controlling for gender and age.

203

The clinical implications of these findings appear substantial. For example, the level

of depression reported by female adolescents experiencing two forms of child

maltreatment and male adolescents experiencing three types of child maltreatment

scored at about 18-19 (on the CES-D scale) which is well above the suggested cut-

off point (16) for depression (Knight, Williams, McGee, & Olaman, 1997; Radloff,

1977). It is also important to emphasize that many young people may be at risk, with

41.8% of females and 20.1% of males who reported having experienced two or more,

and three or more trauma types respectively. These young people may need mental

health care. Additionally, these findings from mainstream sample of adolescents

further emphasize the need for broadly based counselling, support and referral

services in schools.

Multivariate regression analyses allow examination of the significant contribution of

a number of background variables and the relative influence of different forms of

child maltreatment on the physical and mental health of adolescents. Gender, socio-

economic status, family characteristics, and other individual characteristics have

strong influences on the health status of every population, so it is not surprising that

these variables accounted for the largest proportion of variance in each health

outcome (both females and males). Among those background variables, region

emerged as a consistently significant factor affecting the health of adolescents.

Children growing up and living in an urban area like Hanoi, the capital of Vietnam,

are more likely to have better physical health, higher self-esteem, and less depression

and anxiety. This might reflect the fact that although there has been dramatic

development in the past two decades as a result of the “doimoi/reform” policy

introduced in 1986; however, Vietnam is still a poor developing country with more

than 75% of people living in rural areas engaged in agricultural work (O'Donnell,

Doorslaer, & Rosati, 2003). Even though the Vietnamese government has undertaken

a wide range of prioritized projects to support the economic and social development

of rural regions especially remote and mountainous areas, a substantial gap between

urban and rural areas remains and this challenges the next phase of the country’s

reform (MOH et al., 2005). This social and economic inequality between urban and

rural areas has a significant impact on the development of children.

204

As expected, family characteristics such as family arrangement, parent’s marital

status, and quality of parental relationship were strong predictors for mental health,

especially for depression, independent of other demographic and family variables

such as family economic status, age, parental education and occupation. Compared to

children who usually seek help from parents and siblings, those who need to seek

help outside of their close family, have more depression and lower self-esteem. This

might reflect the poor family connectedness or the quality of relationship between

children and other members of the family. These have been documented as risk

factors of depression and low self-esteem (Cash, 2003; Dopheide, 2006; Mann,

Hosman, Schaalma, & Vries, 2004). Self-perception of health of the children

emerged as a consistently significant predictor across male and female samples and

health outcomes. Children who perceived better health (measured by one question of

self-perception of health from very good to very poor) also reported having better

general physical health (measured by adolescents’ self-report symptoms of physical

illness), higher self-esteem and less depression and anxiety. It was also no surprise

that child chronic disease and self-perception of health were the two strongest

predictors of children’s general physical health in the present study. These results

again indicated the validity of the information collected in this study. Consistent with

the literature (Mirza, Davis, & Yanovski, 2005; Pesa, Syre, & Jones, 2000; Siegel,

Yancey, Aneshensel, & Schuler, 1999) we also found that body satisfaction was a

significant predictor for all mental health measures, and especially was the strongest

predictor for self-esteem among female adolescents.

Recently, increasing anecdotes and media reports in Vietnam have been raising a

relatively new phenomenon called educational pressure that might have negative

effects on the health of young people. This has also been observed and reported in

other countries in Asia (Bossy, 2000) and reflects an Asian cultural norm that places

an enormous value on education and the role that education plays in potentially

meeting the family’s social and economic goals and ensuring a secure future for the

child. As a result, it puts intense pressure on the children to be successful at school,

especially for adolescent students who are preparing for university entrance exams.

In the first large-scale study conducted among adolescents and adults in Vietnam

205

funded by UNICEF examining perception and prevalence of child maltreatment,

Michaelson (2004) concluded that academic pressure is a major problem facing

Vietnamese youth, especially for children living in urban areas and that further

investigation on the prevalence, indicators and the effects of this problem is needed.

Another study in Vietnam by Mensch el al. (2003) also found that education is a

major concern or worry for youth. Preliminary findings of these studies as well as the

literature showed that parents and teachers put enormous pressure on children to

succeed and made academic performance the most serious concern for young people

(Bossy, 2000; Hesketh, Ding, & Tomkins, 2003; UNICEF, 2002). Aside from

maltreatment, this type of pressure has the potential for negative health outcomes.

Results from this study revealed that self-report academic achievement, as measured

by the school’s assessment of previous scholastic years, above other background

variables emerged independently as predicting depression, self-esteem and anxiety

for both female and male adolescents. Adolescents who reported getting fair or poor

results in the previous academic year were more likely to suffer depression, anxiety

and low self-esteem than their counterparts with good or excellent academic results.

This finding is in accordance with the literature that documented the correlation

between mental health and academic performance (Cash, 2003; Mann et al., 2004;

Pelkonen, Marttunen, & Aro, 2003) and to some extent contributed to providing

preliminary evidence on the relationship between pressure of education achievement

and health of Vietnamese students, which had never been documented before.

However, whether this is a causal relationship or whether this is an indirect

association remains unclear. While acknowledging that academic performance is

related to students’ mental health via a complex web of factors, socio-economic,

cultural, and cognitive, in the context of education pressure in Asian culture,

academic performance could be a major risk factor for Vietnamese students’ mental

health. There may be two possible pathways. First, growing up in a society where

having constantly good academic results is believed to be the only way for their

success in adulthood can make students put a lot of pressure on themselves. It might

directly cause mental health problems for students. Second, the relationship between

academic achievement and students’ mental health might be mediated by other

206

factors. Quantitative and qualitative evidence from several recent studies in Vietnam

revealed that parents and teachers physically or emotionally maltreated children as a

method to force them to get good study results. This is not uncommon practice

nowadays in Vietnam (UNICEF, 2002). Nearly one third of children surveyed in a

study conducted in four provinces in Vietnam reported that not performing well at

school was the reason for them to be physically or emotionally maltreated by adults

(PFCSI & SCS, 2005). Accounts from students participating in qualitative interviews

in our research also revealed this problem: “My friends often talk about corporal

punishment at home for example one of my friends often said to me that ‘I was

physically punished by my parents because I got a bad mark’” (14 year old girl,

Chilinh).

In this study, multivariate regression models allowed us to evaluate the extent to

which child maltreatment experiences influence adolescent health collectively and

independently after controlling for a wide range of other essential background

factors. The most consistent findings across gender and health outcomes were that

four types of child maltreatment collectively had significant effects on both mental

and general physical health of adolescents independent of the contextual factors that

have been proved to influence psychological adjustments and physical health. This

study supports findings from a small body of previous work that simultaneously

examined, within a broader context, the influence of several types of child

maltreatment on various measures of psychological adjustments, in normative and

special children as well as adult samples in Western countries (Higgins & McCabe,

2000b; Meyerson, Long, Miranda, & Marx, 2002; Turner et al., 2006). There is no

earlier research available examining the combined impact of various types of child

maltreatment on the self-reported general physical health measure of the victims.

The present study supports a suggestion that child maltreatment may not only be the

outcome of a negative family environment and social context, which probably

mediates the effect of victimization, but also is an independent source of trauma with

negative physical and mental health correlates.

207

Furthermore, this study is among only several studies worldwide that provides results

concerning the independent influence of different types of child maltreatment on

trauma symptomatology in normative samples, with contextual factors and other

maltreatment domains controlled. The observation that different forms of

maltreatment independently influenced depression, anxiety, self-esteem, and physical

health was relatively consistent for both females and males. In general, although all

four forms of child maltreatment have their relative contribution to variance in

adolescent health, in most cases child emotional maltreatment and neglect had the

strongest independent correlation with depression, anxiety, self-esteem, and physical

health. Emotional maltreatment had consistently significant effects on all health

outcome measures in both female and male adolescents. This result corroborates the

finding from Higgins’s study in an Australian adult sample (Higgins & McCabe,

2000b), and suggests that child emotional abuse and neglect might be more

destructive in their influences on the young victims than other types of victimization

(Crosson-Tower, 2005; Hildyard & Wolfe, 2002; O'Hagan, 1993).

Interestingly, close examination suggested that physical maltreatment had a different

effect on anxiety and general physical health for males and females. Physical

maltreatment had stronger effects on anxiety and physical health among females than

among males and emerged as significantly independent predictor of these health

outcomes for females after controlling for other maltreatment forms. This finding is

different to that reported by Meyerson et al. (2002) whereby physical abuse

significantly predicted depression and distress for males but not females in the study

of 131 USA high risk group of adolescents living at Job Corps facility, a place for

adolescents referred from the department of Human Services or Juvenile court or

discharged from inpatient care because they did not have an alternative residence.

Numerous differences in sample characteristics between these two studies regarding

the prevalence and severity of abuse as well as the social and cognitive factors which

might impact on mental health could be the main reason for the difference in the

findings.

208

The total variance of depression and self-esteem measures explained by various

maltreatment types variables (R2 change) (depression: .07 for males and .088 for

females; self-esteem: .044 for males and .05 for females) and by final models

(adjusted R2) (depression: .28 for males and .26 for females; self-esteem: .23 for

males and .28 for females) in the present study are comparable with that of previous

studies conducted in community-based samples of children and adolescents (Turner

et al., 2006) (adjusted R2 of depression: .228 for 2-9 year old sample; and .20 for 10-

17 year old sample) and a community adult sample (Higgins & McCabe, 2000b)

(self-esteem: .05 for R2 change; and .33 for adjusted R2) in Western countries.

Moreover, it is noteworthy to examine the squared semi-partial correlation (sr2)

which is the unique contribution of the independent variable to R2 in a set of

independent variables (Tabachnick & Fidell, 2001). For all four child maltreatment

types, although each had its unique effect on health, with emotional maltreatment

being the strongest predictor, in most of the cases more than half of the health

outcome measures’ variances explained by child maltreatment were contributed to by

two or more types of victimization. For example, in models predicting depression,

out of 7% (among males) and 8.8% (among females) the overall depression variance

explained by four types of child maltreatment was only 2.9% and 3.7% respectively.

This is equivalent to the sums of variance independently explained by each type of

maltreatment. Therefore, it is evident that while different forms of child maltreatment

have their own direct influence on the health of the victims, the co-occurrence of

child maltreatment significantly contributes to increase the risk of mental and

physical health problems.

7.4 Strengths, weaknesses and implications for further research

The literature review revealed gaps in previous studies in the area of child

maltreatment that focus on only one or two forms of child victimization when

estimating the impact of maltreatment experiences upon health and well-being.

Additionally, many experts have strongly emphasised the importance of taking into

account the family and social context while examining the consequences of child

209

maltreatment (Boney-McCoy & Finkelhor, 1996; Fergusson & Mullen, 1999; Nash,

Neimeyer, Hulsey, & Lambert, 1998). The present study was designed to fill these

gaps by examining simultaneously four main forms of child maltreatment taking into

account the possible effects of broader background factors including various

demographic, family characteristics and child characteristics. With this approach it is

expected that the estimated effects on adolescents’ health risk behaviours and health

problems of each form of child maltreatment and the co-occurrence of the

victimization would be more accurate.

Cultural appropriateness was carefully considered in the questionnaire development

process and data collection procedure of this study. The final questionnaire used in

the study was developed based on international and local literature, qualitative study

among important stakeholders and careful translation and back-translation

procedures according to accepted guidelines for cross-cultural research (Guillemin,

Bombardier, & Beaton, 1993).

As mentioned, this study is among the first of its kind conducted in Asian countries

in general and in Vietnam in particular. The study provides valuable evidence on the

extent to which the problems of child maltreatment exist and also underlines its

harmful effects in the context of Asian culture. Although the study was designed in

an attempt to take a relatively comprehensive approach in examining the complex

child maltreatment issue, some limitations of this study must also be taken into

account in the interpretation of the findings.

First, this study is cross-sectional in nature, so it is impossible for us to determine the

direction of causation between several groups of variables, such as background

variables and child maltreatment, background variables and health outcomes, and

child maltreatment and health outcomes. Therefore, prospective, longitudinal

research in the future which tests the possible models of how a wide range of risk

and protective factors predict health and health related behaviours is necessary to

determine pathways that explain how child maltreatment can influence health in

Vietnamese adolescents.

210

Another weakness in our study is related to the nature of our sample, which consisted

of representative students at secondary and high schools in two districts (Chilinh and

Dongda) in the North of Vietnam. The findings therefore might not be generalisable

to the overall population of adolescents in Vietnamese society. Additionally,

although it is estimated that a significant proportion of Vietnamese adolescents (more

than 75% aged 14-17 years old) are in schools (MOH et al., 2005), this study did not

capture the more than 20% of adolescents who never go to school or drop out. Given

that children who do not have the benefits of school may be at high risk for many

adversities, findings of this study may underestimate the maltreatment rates and the

extent to which they influence adolescent health. It is therefore recommended to

conduct future studies on this topic among nationally representative samples of

people in various age groups.

Third, as with many earlier studies in this area, all data were assessed by

retrospective self-report, this may have resulted in under-reporting of maltreatment

events due to difficulties in recall and disclosure. The problem of potential recall bias

may also influence the accuracy of research findings in the other direction, whereby

adolescents with current adjustment problems possibly are more prone to recall and

report their adverse experiences. Such recall bias might lead to over-estimation of the

relationship between maltreatment problems and health outcomes, even though little

evidence is available to support the extent or nature of this bias (Fergusson &

Mullen, 1999). However, given the fact that most children’s adverse experiences are

never officially reported, especially in Vietnamese society where a child

maltreatment report system does not exist, self-report remains a valuable source of

information.

Another important limitation is the usage of the mean score cut-off point in this study

to classify abuse groups for each type of child maltreatment. Statistically, this may

result in prevalence estimates for each form of maltreatment around 50% if the

pattern of endorsement of each maltreatment scale is nearly normal. This approach

can also be subjected to the criticism that it does not take into account the norms

regarding what is considered to be abusive by community and child protection

211

experts in Vietnam or even by international standards. In the literature review and

methodology chapters, it has already been mentioned that the operational definition

of each form of child maltreatment is a matter of much scientific debate

internationally. At present, there is no “gold standard” that researchers can use to

estimate various forms of child maltreatment prevalence which can be comparable

across cultures.

It is arguable that “simplicity is the best” and we should base comparisons on

estimates of prevalence of behaviourally specific maltreatment events. However, this

often leads to inordinately high estimates of “abuse” prevalence if we settle for

simple event/non-event classification. One negative practical impact of reporting

very high rates from surveys is that often these do not have face validity for

professionals and the general community and the research can be dismissed out of

hand. The essential problem is that maltreatment prevalence is heavily influenced by

the width of the range of questions asked (Gorey & Leslie, 1997). In the absence of a

culture-free and globally accepted instrument, we created a tool by pooling items in

four maltreatment sub-scales based on extensive literature review, as well as

incorporation of abuse events suggested by qualitative research with young people in

Vietnam. The event/non-event prevalence estimates for each item are shown in tables

4.4; 4.5; 4.6 and 4.7, and this is followed by the prevalence estimates for three levels

of abuse severity, based on the summative scale scores. Therefore, in this thesis the

item by item prevalence estimates for adverse experiences are presented so they can

be used for international comparison of basic indicators, and the summative scores

are shown to indicate the proportions of this sample of adolescents who may have

been mildly or more seriously “abused”.

Despite this endeavour, it can be argued that a preferable alternative approach is to

create a categorical classification for each type of child maltreatment. This should be

based on the norms regarding violent acts toward the child as suggested by typical

attitudes and/or professional experience of relevant stakeholders. Further research is

necessary in Vietnam and indeed in all Asian societies. A broad program of research

should include qualitative, focus-group and one to one interview inquiries into

212

norms. The strategy should also include systematic analyses of experts’ opinions (eg

Delphi studies) to determine if consensus can be gained. Such research may identify

cut-off points for each maltreatment scale by using the Receiver Operating

Characteristics method which considers the assessment made by clinicians as the

“gold standard”, as has been done in several previous studies in other countries

(Fernandopulle & Fernando, 2003; Walker et al., 1999).

Fifth, to measure various forms of maltreatment experiences this study used a Likert-

type scale with ratings from never, rarely, sometimes, often to always. Such

categories may be vague and vary in interpretation from respondent to respondent

which can increase response variability (Myers & Winters, 2002). However, Hamby

and Finkehor (2000) argued that there is no empirical evidence to demonstrate which

response categories are the best for use with children and adolescents. Asking

respondents to give precise numbers of maltreated episodes can be too demanding.

Indeed, in this study the focus group interviews suggested with adolescents do not

like to estimate numbers of abusive incidents. Against this background, it was

decided that a 5-point rating from never to always is most appropriate.

Sixth, in this study when analysing correlations between maltreatment variables and

various health outcomes, Likert-type scales measuring four forms of maltreatment

were treated as interval data. A reasonable question is whether these are truly

continuous variables because there is not a constant spacing between the values. In

practice, however, the Likert-type scale may be treated as if continuous provided that

the data meet other assumptions of the analysis (Tabachnick & Fidell, 2007).

Additionally, using Likert–type scales as continuous variables to measure different

forms of maltreatment has been supported by numbers of researchers because there

are advantageous from statistical and analytical perspectives. This approach

enhances reliability and maximises statistical power (Bernstein et al., 2003; Higgins

& McCabe, 2001a).

Finally, regarding instruments used in this study to measure health outcomes, four

scales including depression, self-esteem, anxiety and physical health were employed.

213

While vigorous procedures were used to construct and validate depression, self-

esteem and anxiety scales, a similar approach could not be employed for constructing

and validating the physical health scale, due to the absence of strong, guiding

hypotheses regarding impacts on physical health, and resource limitations of the

researcher. It is therefore suggested that this scale should be tested and validated in

future research.

7.5 Conclusion

Enormous efforts on research into child maltreatment have been made over nearly

four decades. However, most studies have been conducted in English speaking and

developed countries and focused only on a single form of child maltreatment,

predominantly on childhood sexual and physical adverse experiences. The present

study extends a small body of previous research examining poly victimization in

developed nations to an Asian country, and contributes some new insights to

international knowledge on cross-cultural child maltreatment problems. We have

found considerable commonalities as well as some differences in the findings from

our study compared with earlier research.

The results revealed the relative widespread existence of various forms of child

maltreatment as in other places worldwide where they have been measured. In

general, the proportions of adolescents in our study who reported experiencing

different types of victimizations fall within the range of international findings.

Startlingly, a high rate of sexual abuse of male children – higher than among females

was found in this study. This pattern is different to those which were reported from

previous studies and needs to be explored in future research. Consistent with earlier

research, our study also indicates that co-occurrence of various forms of child

maltreatment is not uncommon. Although the significant predictors of each type of

child victimization varied, in accordance with many earlier studies quality of parental

relationship and factors related to child connectedness with other members in the

family emerged as consistently significantly associated with every form of

maltreatment.

214

Another significant conclusion, in agreement with previous studies, concerns the

independent correlations between various types of child maltreatment and health,

including a wide range of health risk behaviours, depression, anxiety, self-esteem,

and general physical health, while controlling for other domains of victimization and

different background factors. While every form of child maltreatment had its own

significant associations, emotional maltreatment emerged as the strongest risk factor

for the health of victims. This finding has a significant implication in terms of the

urgent need to raise public awareness on harm not only from sexual and physical

abuse but also other forms which have received less attention.

This study provides important findings regarding the cumulative effects on different

outcomes of multiple forms of child maltreatment, which had been reported in only a

few other studies in developed nations. Co-occurrence of different types of child

maltreatment had strongly and consistently graded relationships with various health

risk behaviours, and mental and physical health of maltreated adolescents.

Furthermore, as co-occurrence of various types of child maltreatment is common and

maltreatment forms share a significant proportion of the variance in health outcomes,

it is important that the effects of any type of child maltreatment should be examined

only within the context of assessing the potential variance contributed by other

maltreatment forms.

Vietnam is still in the early stage of the battle against child maltreatment. The

findings from the present study provide valuable and timely evidence that can be

used to increase public awareness as well as develop and implement appropriate

responses to child maltreatment. To be effective, apart from learning experiences

from other countries, the public health response to child maltreatment in Vietnam

should be based on evidence relevant to local social and cultural contexts. More

studies are needed to extend the current research to national representative samples,

to examine child maltreatment effects on other outcome measures and to

comprehensively test potential risk and protective factors for different forms of child

maltreatment. When we have this vital information, we should be able to design and

implement effective prevention programs.

APPENDIX 8

Main themes emerging from the qualitative study

319

Main themes emerging from the qualitative study

1. Perception of child maltreatment (understanding of child maltreatment):

“…exploitative child labour or behaviours that affect children’s health in terms of

physical or mental aspects…also sexual abuse nowadays features frequently in

newspapers and media”.

(Male teacher, Hanoi)

“A common type of child maltreatment now is lack of care for children in the

broader sense that is not only lack of care for materials but now many families in

cities can earn a lot of money and give money to children and they think that is

enough. It really creates a new social problem. On the other hand, in many rural

areas in Vietnam parents still have perception that - God produces elephants and

God produces grass - and they never think that failing to provide children with care

could be considered maltreatment”

(Female teacher, Hanoi)

“Child abuse is understood that now many families do not treat children well, for

example, not supporting children studying, parents travelling for doing business and

leaving children with their relatives. In Chilinh now increasing numbers of parents

are working abroad; their children stay at home and those children are at risk of

maltreatment”.

(Female teacher, Chilinh)

“According to me some abusive behaviours that happen in the family may be due to

the parents not knowing they actually did abuse their children”.

(Mother, Hanoi)

All children FGDs mentioned the following idea about child maltreatment:

Force children to work to make money especially doing something illegally… in

general any actions that not support the rights of the child that they know something

320

about from schools such as physical violence toward children, humiliate children, do

not respect children’s voice, not supporting children studying …

2. Type of abuse: (listed in order from high to low frequency mentioned by

informants)

- Sexual abuse (mainly referring to severe acts such as rape, attempted rape);

- Don’t love children; insult children; threaten children;

- Do not support children’s studies;

- Beating children up by parents and family members;

- Adults hit children in the streets, public areas…;

- Parents are not emotionally available for children such as too focus on

making money and not close to children (especially happed nowadays in

economic better off families);

- Violence towards children mainly in school by older school-mates

(predominantly boys).

3. Different thinking about physical punishment

“Beaten by parents when you did something wrong is OK but beaten for no reason

that is abuse”.

(Boy FGD1, Hanoi)

“I saw my friend beaten up badly by his parents but I am not sure whether he did

something wrongly that made them do that”.

(15 year old boy, Hanoi)

“Beating is only partly abuse because it is to educate children. It is necessary to be

tolerant to parents as sometimes they beat children hardly just because parents are

angry about something and then beating children instead, as expressed by the phrase

- Angry with fish, chop the chopper board-”; “Beating children to educate them is not

abuse”.

(Girl FGD1, Chilinh)

321

“Teachers beating students is not always abuse, if the student is too naughty beating

is OK. Also partly because of the parents, if the parents are busy with work they ask

teacher for help to support children studying better”.

(Girl FGD2, Chilinh)

“I am asked by parents to conduct corporal punishment with their children, and I

think it is necessary for them to become good people”.

(Female teacher, Chilinh)

“Beating children in family or outside family all are unacceptable. Even some

parents beat their children for no reason such as parents are angry with somebody but

beat their own children instead”.

(Boy FGD1, Chilinh)

“We wish not to be beaten by parents but not sure whether corporal punishment is

good method of raising children or not”.

(Boy FGD2, Chilinh)

“I know some parents kick or beat their child badly, it is not good they maltreat their

child, they wrongly assume that children have to do what parents want”.

(Father, Chilinh)

“In family, parents hit their children only if they are too angry or want children to be

better or children are too naughty so that is not abuse”.

(16 year old boy, Chilinh)

4. Child maltreatment examples

“My friend has to leave school for several days whenever her family has some work

that they have to do during school hours”.

(Girl FGD1, Chilinh)

322

“Whenever my mother is angry she insults me as a dog and it happens very often. I

feel very upset but I have to get use with that and to take it easy now”.

(15 year old boy, Hanoi)

“My parent hit me hard when they are very angry”.

(16 year old boy, Hanoi)

“My friends often talk about their corporal punishment experiences at home, for

example one of my friends said to me that ‘I was physically punished by my parents

because I got a bad mark”.

(14 year old girl, Chilinh)

“In my neighbourhood there are many children aged about 12-14 working as maids

in families and being treated badly”.

(15 year old girl, Hanoi)

“I heard my friends living in this town say that many families have maids as children

now and they shout at or beat up those children very often. I also know 1 case like

that (a girl about 12-13 years old) working for my neighbour’s family”.

(13 year old boy, Chilinh)

“A boy, he is my neighbour always beaten up by his drunk father and another boy

living in my alley was forced by his parents to leave school from grade 5 or 6 to

work for his family street vender to earn money…. But I do not think his family are

too poor to afford for his schooling …. poor him!!!”

(15 year old boy, Hanoi)

323

“I know quite a few cases that fathers of my students “strictly educate” their children

but those fathers actually physically and emotionally abused children because fathers

kick or beat children up or even tie up or chain them and using electric wire to hit

them leaving children with bruises and scratches. Parents also lock and insult

children by saying that - if you don’t study I will feed you as a dog under the bed”.

(Female teacher, Chilinh)

“My friend, she is 2 years older than me, told me her experience as that her

neighbour, this guys is 5 or 6 years older than her – I also know this man. He

followed her to behind of the house where she had to do housework and hugged her

and wanted to do something… she is too scared and ran away but does not dare to

talk to anybody about that”.

(15 year old girl, Chilinh)

“One of my relatives, she also told me that a man – a friend of her family - he

hugged and kissed her when he drunk and she was lucky to escape otherwise she

does not know what terrible thing would have happened”.

(16 year old girl, Chilinh)

“I could not forget the true case in my village: a 12 year old girl had been raped to

death by a man, he is friend of her family, with several other men, in an abandoned

shelter”

(17 year old girl, Chilinh)

5. Who are perpetrators (listed in order from high to low frequency reported by

informants)

- Strangers

- Parents/guardians

- Neighbours

- Relatives

- Family friends

324

- Older adolescents

- Teachers

6. Trend of child abuse prevalence

All key informants agree that child abuse in Vietnam is increasing. The main reasons

inspire them to give this comment are: it is frequently mentioned on newspapers,

mass media, adults in the family (parents, grandparents) and because of the social

changes nowadays.

Child abuse is on the rise… because we hear about it more often on mass media but

we also think it really increases because parents now are too busy with earning

money; as a result, they have not got time to take care of their children so more

adolescents are being abused.

(Girl FGD1 and 2, Chilinh; Boy FGD 2, Hanoi; Teachers from Hanoi, teachers from

Chilinh)

“I think child maltreatment is an issue that seems to increase because the society is

changing and becoming more complicated. Parents now are too busy earning a living

so have less time to take care of their children, especially for poor families”.

(17 year old boy, Chilinh)

7. Source of information on child abuse:

- Newspapers, especially adolescent newspapers and magazines;

- Television;

- Adults in family;

- Friends; and

- Their own observations on the streets, neighbourhood, in schools.

325

8. Expected measures to prevent child maltreatment

- Parent should spend more time with children;

- Educate both parents and children;

- Provide more information and campaigns;

- Community system should strengthen to consider child maltreatment issues in

families as a social issue rather than an individual family business;

- Clear and effective report systems.
