Sorority members may be at greater risk than other college women for sexual violence and intimate partner violence (IPV). The authors evaluated the Bringing in the Bystander in-person program with sorority members who participated in the program (n = 30) compared with those who did not (n = 18). Results indicate that program participants showed increased bystander efficacy, likelihood to help, and responsibility for ending violence without unintended "backlash" effects. Implications include a call for future programming with more diverse sorority members over longer time. In addition, the authors discuss what the findings might mean for formal campus policies and practices for preventing sexual violence and IPV. (Published Abstract)
