Methodology Standard international protocol Sampling Questionnaire (content, translation and sections/questions order) Survey administration Data coding and entering Strict quality controls at each stage

Sampling Target population : school-aged children Sampled population : 11, 13 & 15 years old in countries where school system makes it possible All school-age children from the 5 th grade in primary to the last grade in secondary schools in French-speaking Community and Flanders In French-speaking Community: Sample built in proportion with population size (Provincial level) and school networks (French community, province, municipalities and catholic education network) In Flanders: probability proportional to size (PPS) = size of schools taken into account. Every pupil has the same chance to be included.

Questionnaire Core questions : Compulsory (basis of international data) Optional packages: In-depth specific areas Opportunity to insert local questions (not in the protocol) Self-administered in class under supervision of a school staff

Conclusions High frequency of alcohol use (70% in last 30 days in FWB and 76% in Flanders) A substantial amount of adolescents also engage in risky alcohol use (such as early experimentation and drunkenness) This last group are more likely boys, are older, have a higher family affluence, have a poor health and life satisfaction and engage in other risky behaviours

Strengths and weaknesses + Unique study on this topic and with this methodology Large scale study Validity of questionnaire Repeated measures (time trends) International comparisons - No information on absents (e.g. sick children, truancy), dropped-out pupils Decline of participation rate (school level)
