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

Abstract

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