A Meta-Analysis of School-Based Interventions Aimed to Prevent or Reduce Violence in Teen Dating Relationships

The incidence of violence in dating relationships has a significant impact on young people, including decreased mental and physical health. This review is the first to provide a quantitative synthesis of empirical evaluations of schoolbased programs implemented in middle and high schools that sought to prevent or reduce incidents of dating violence. After a systematic search and screening procedure, a meta-analysis of 23 studies was used to examine the effects of school-based programs. Results indicated school-based programs influence dating violence knowledge ( g = 0 22 . , 95% confidence interval [0.05, 0.39]) and attitudes ( g = 0 14 . , 95% confidence interval [0.10, 0.19]); however, to date, the results for dating violence perpetration and victimization indicate programs are not affecting these behaviors to a significant extent. The results of this review are encouraging, but they also highlight the need for modifications to dating violence prevention programs including the incorporation of skill-building components and a need to address the role of bystanders.
