The purpose of this qualitative study was to investigate factors influencing the adoption of an effective bystander-based sexual violence prevention intervention. High schools participating in a cluster-randomized controlled trial that found significant declines in sexual violence over time and with full implementation were invited to adopt this program (Green Dot) at no cost. Three emergent themes arose from interviews with 10 intervention implementers. These findings have implications for researchers, practitioners, and high school administrators and may facilitate future program marketing efforts and the development and testing of strategies for targeted dissemination of this and other bystander programs for violence.
