Fostering college students' responsibility as prosocial bystanders to sexual violence prevention: A meta-analysis of the Bringing in the Bystander program.

To synthesize research examining the effectiveness of the sexual violence bystander program (). The analytic sample included 2083 youth in the treatment group and 969 in the comparison group. A search strategy that included a total of 45 search terms was applied to 28 electronic databases. The systematic search yielded a final analytic sample of 14 evaluations, with 38 independent effect sizes calculated across four outcome measures: rape myth attitudes ( = 11), bystander efficacy ( = 11), bystander intentions ( = 11), and bystander behavior ( = 5). The program produced significant, positive pooled effects on measures of rape-supportive attitudes, bystander efficacy, and bystander intentions. The overall results are promising and suggest that the education program may be an effective tool for targeting sexual violence on campuses.
