The purpose of this study is to evaluate the statewide application of Green Dot among high schools students. We hypothesize that students in high schools with Green Dot will over time report lower rates of sexual violence (SV) compared with students in comparable high schools randomized not to have Green Dot. This reduction in sexual violence will be mediated through a reduction in social norms supporting sexual violence (measured with violence acceptance scales) and an increase in bystander behaviors.
