Is the concept of ‘Mental Disorder’ problematic? “I should like to make clear, therefore, that

although I consider the concept of mental illness to be unserviceable, I believe that psychiatry could be a science. I also believe that psychotherapy is an effective method of helping people – not to recover from an ‘illness’ but rather to learn about themselves, others and life.” Szasz

Page 11: Abnormal psychology 1b

Two broad ways to define mental disorder

In general, the concept of “mental disorder” can be defined as:A biomedical, culturally independent,

value-free conceptOr as a social, culturally relative,

value-based concept.

Page 12: Abnormal psychology 1b

Overview of definitions that will be discussed Mental disorder as a statistical deviation Mental disorder as dysfunction Mental disorder as personal discomfort Mental disorder as maladaptive

behaviour Mental disorder as norm or value

violation

Page 13: Abnormal psychology 1b

Mental disorder as statistical deviance

A person has a mental disorder when their behaviour, ability, or experience is significantly different from average.

Page 14: Abnormal psychology 1b

Mental disorder as statistical deviance

Page 15: Abnormal psychology 1b

Mental disorder as statistical deviance Problems: We want to use the term disorder to

describe some conditions that are statistically frequent

“positive” deviations are not distinguished from “negative” deviations

we do not want to call all “negative deviations a disorder

Page 16: Abnormal psychology 1b

Uggo Betti: “All of us are mad. If it weren’t for the

fact that every one of us is slightly abnormal, there wouldn’t be any point of giving each person a separate name.”

Page 17: Abnormal psychology 1b

Mental disorder as a dysfunction

A person has a mental disorder when a mental mechanism is not performing the natural function it was designed to perform.

Problems:Natural selection does not “design”

mechanisms

Page 18: Abnormal psychology 1b

Sedgwick (1982): “All sickness is essentially deviancy

from some alternative state of affairs which is considered more desirable…The attribution of illness always proceeds from the computation of a gap between presented behaviour (or feeling) and some social norm.”

Page 19: Abnormal psychology 1b

Mental disorder as a dysfunction

Problems cont:For many mechanisms there is a wide

range of adaptive functioning across people and situations (fear response).

Page 20: Abnormal psychology 1b

Mental disorder as a dysfunction

Problems cont:Many things that we want to call a

disorder might actually be adaptive reactions.

Page 21: Abnormal psychology 1b

Mental disorder as personal discomfort

A person has a mental disorder if they experience personal distress.

Problems:What about the person who abuses

drugs or believes they are receiving messages from outer-space – without experiencing distress?

Page 22: Abnormal psychology 1b

Mental disorder as maladaptive behaviour

A person has a mental disorder if they engage in behaviour that prevents them from meeting the demands of life.

Problems:There may be situations that people

should not adapt toThis approach emphasizes “fitting in” as

being ultimately important

Page 23: Abnormal psychology 1b

Mental disorder as norm or value violation A person has a mental disorder if they

have experiences and exhibit behaviours that are inconsistent with the norms and values of society.

Examples:Behaviour that is harmful to oneself or

othersPoor reality contactInappropriate emotional reactionsErratic behaviour

Page 24: Abnormal psychology 1b

Mental disorder as norm or value violation

Problems:What if violation is result of external

circumstancesSuch a criteria can seem too arbitrary

and open to abuse

DSM-IV definition of mental disorder

A mental disorder is “conceptualized as a clinically significant behavioural or psychological syndrome or pattern that occurs in an individual and that is associated with present distress or disability or with a significantly increased risk of suffering death, pain, disability, or an important loss of freedom.”

Page 27: Abnormal psychology 1b

DSM-IV definition of mental disorder “The syndrome or pattern must not be

merely an expectable and culturally sanctioned response to a particular event, for example, the death of a loved one.”

“It must currently be considered a manifestation of a behavioural, psychological, or biological dysfunction in the individual.”

Page 28: Abnormal psychology 1b

Cross cultural issues

How one thinks about the role of culture depends on your definition of mental disorder

Page 29: Abnormal psychology 1b

Cross cultural issues

If biomedical, then culture influences how a disorder impacts members of different culturesDifferent riskIdiom of distress

Page 30: Abnormal psychology 1b

Cross cultural issues

If culturally based, then influences what will be considered a disorderBehaviour or experience may not be a

“disorder” in all cultures

Page 31: Abnormal psychology 1b

Non-Western approaches to mental disorder

Often do not separate psychology and spiritualityDisruption in relation to spirit world

Often based on more collective and less individualistic conceptualizationsDisruption in interpersonal relations
