Although sexual assault prevention programs have been increasingly successful at improving knowledge about sexual violence and decreasing rape-supportive attitudes and beliefs among participants, reducing sexually assaultive conduct itself remains an elusive outcome. This review considers efforts to support change for individuals by creating prevention strategies that target peer network and community-level factors that support sexual violence. To this end, the article examines successful ecological prevention models from other prevention fields, identifies the components of multilevel prevention that appear critical to efficacy and discusses their application to existing and emerging sexual violence prevention strategies.
