Impact of Exposure to Sexual Violence Prevention Messages on Students' Bystander Behavior.

Bystander intervention is a prevention strategy commonly used to address campus sexual violence. Increasingly, there are calls for prevention efforts to be multilevel and ongoing. The current study investigated the impact of receiving varied prevention messages throughout adolescence and into early adulthood to determine whether it influences college students' awareness of sexual violence, willingness to intervene as a helpful bystander, and actual prosocial bystander behavior. These questions were tested through administration of an online survey to a racially and ethnically diverse sample of 1,047 undergraduate students at a large, urban university in the mid-Atlantic. Results found that most students received information about sexual violence prior to coming to campus from a variety of sources, and that the sources varied significantly by gender and race. Regression analysis found that greater exposure to prevention messages prior to coming to college was significantly associated with greater bystander intentions and behavior even after accounting for gender and race and exposure since coming to college. The findings provide initial support to expand the scope of prevention efforts and to begin them prior to college.
