Abstract

Aims:  This study aimed to assess the effectiveness of the Örebro prevention program (ÖPP), an alcohol misuse prevention programme that aims to reduce youth drinking by changing parental behaviour. Design:  Cluster-randomized trial, with schools randomly assigned to the ÖPP or no intervention. Setting:  Forty municipal schools in 13 counties in Sweden. Participants:  1752 students in the 7th grade and 1314 parents were assessed at baseline. Students' follow-up rates in the 8th and 9th grades were 92.1% and 88.4% respectively. Measurements:  Classroom questionnaires to students and postal questionnaires to parents were administered before randomization and 12 and 30 months post-baseline. Findings:  Two-level logistic regression models, under four different methods of addressing the problem of loss to follow up, revealed a statistically significant programme effect for only one out of three drinking outcomes under one loss-to-follow-up method, and that effect was only observed at the 12-month follow up. Conclusions:  The Örebro prevention programme as currently delivered in Sweden does not appear to reduce or delay youth drunkenness.
