Bystander Intervention for the Prevention of Campus Sexual Violence: Opportunity, Frequency of Action, and Consequences for Confronting Those at Risk of Perpetration.

This cross-sectional study examined students' (Campus 1, n  = 1,153; Campus 2, n  = 1,113) experiences with four situations of direct confrontation of those at risk for sexual assault perpetration. The most reported opportunity was to confront those making false statements about sexual assault; many students reported more than one opportunity to intervene in the past year. Bystanders intervened most of the time across the four situations examined in this study. The most reported consequence of intervening was that no further harm was caused. More nuanced measures can offer practitioners further information to tailor sexual violence prevention programs.
