Understanding adolescent binge drinking in Spain: how school information campaigns moderate the role of perceived parental and peer consumption

Despite its potentially harmful effects, adolescent binge drinking is becoming increasingly common worldwide. To enable the design of more effective school information campaigns, the underlying factors of heavy alcohol use must be carefully analysed. This study investigated how individual, social and contextual factors relate to adolescent binge drinking. It also explored whether adolescents' exposure to information campaigns at school moderates the relationships between perceived parental and peer alcohol consumption and adolescent binge drinking. We used data from a Spanish nationwide representative sample of 47 803 students aged 14-18 years, of whom 25 576 had engaged in binge drinking behaviours. Data were collected every 2 years between 2006 and 2012. For the multilevel estimation in 2012, the sample comprised 10 577 students. Whilst perceived problems associated with binge drinking and perceived difficulty in accessing alcohol were associated with low levels of binge drinking, adolescents' perceptions of parental and peer consumption were associated, to a greater degree, with high levels of binge drinking. School information campaigns moderated the relationship between parental consumption and adolescent binge drinking but not the relationship between peer consumption and adolescent binge drinking. We conclude by highlighting implications for policymakers and offering possible directions for future research.
