Introduction
• Smoke passes through water before inhalation (1)
• Getting popular in Europe especially among young people (2)
• Few studies which lack validation
and standardization (3)
• Has common and unique dependency aspects, and can not be measured in traditional cigarette dependency tools (4)
How to measure waterpipe tobacco smoking dependency (WPTS)?
• New validated tool: Lebanon Waterpipe Dependence Scale (LWDS-11) (5)
• 4 domains covered: • Physiological dependency - Psychological craving • Positive reinforcement, - Negative reinforcement • 11 questions: each question (0-3),score (0-33)
• Arabic and English sets
• less likely (≤ 9 scores) and more likely (≥10 scores) WPTS dependent
Research Aims
• To evaluate the psychometric properties of the Lebanon Waterpipe Dependence Scale (LWDS-11)
• To assess, estimate and identify factors
associated with WPTS dependence syndrome amongst UK male adult resident waterpipe smokers
Methodology
• Cross sectional survey• 8 shisha premises participated• Random time table,180 participants in 4 weeks. • Questionnaire in face to face interview • QMUL Research Ethics Committee approved the study
• Sociodemographic factors1
• Waterpipe module of Global Adult Tobacco Survey (GATS)2
• LWDS-11 3
Questionnaire
Sample Background
What is the level of WPTS in the sample
ExplanatoryVaiables
Unadjusted (Univaraite analysis)
Adjusted (Multivariate analysis)
Being Arab 6.06 (2.12-17.31)* 2.63 (1.05-6.62)*
Low education level 3.72 (1.49-9.28)* 1.26 (0.76-2.09)
Daily WTS in the past 4.31(2.29-8.06)* 2.13 (1.30-3.49)*
last WTS session at home
4.0 (1.51-10.63)* -----------------
WTS alone in last session 3.57 (1.64-7.78)* 1.31 (0.80-2.15)
Factors associated with WPTS dependency
*p<0.05
LWDS-11 Evaluation
• Two questions did not discriminate validity• Adequate reliability (Cronbach’s alpha coefficient α =0.74)• Physiological dependency (33.62 variance, α =0.8)• Positive and negative reinforcement (14.80 variance, α =0.5)
• LWDS-11 discrimates between mild, moderate and heavy
WPTS based on number of tobacco waterpipe smoked per a
week
LWDS-11 Evaluation
• Two questions did not discriminate validity• Adequate reliability (Cronbach’s alpha coefficient α
=0.74)• Physiological dependency (33.62 variance, α =0.8)• Positive and negative reinforcement (14.80 variance, α
=0.5)• LWDS-11 discrimates between mild, moderate and heavy
WPTS based on number of tobacco waterpipe smoked per a week
Conclusion
Just below half of sample were more likely WPTS dependents
Adequate reliability of LWDS-11 especially in physiological dependency in addition to positive and negative reinforcement.
Validity and cross cultural usage of LWDS-11 should be further investigated in future research
WPTS dependency were associated with being Arab, smoking WPTS daily in the past, and increasing duration of last WPTS session
