Initiative Description: Meta-analysis summarizing the effectiveness of school-based brief alcohol interventions (BAIs) among adolescents. 17 studies eligible for inclusion. Motivational enhancement therapy was the most effective modality, but was rarely implemented in group-delivered intervention
Study Results: School-based BAIs are effective in reducing adolescent alcohol consumption, but may be ineffective if delivered in group settings. Future research should explore whether group-delivered BAIs that use motivational enhancement therapy components may yield beneficial outcomes like those observed in individually-delivered programs.
