NCT01878097

Brief Summary

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.

  • Average Number of Sexual Assault Events Used (Perpetrated) Per School.

    Students self report of sexual assault perpetration averaged at the school level and adjusted for baseline and number of students. Adjustments were made by including baseline measure and number of students as a covariate in the model. Data will be collected at baseline and annually for 4 years.

    up to 5 years follow up from baseline intervention

  • Average Number of Sexual Assaults Experienced (Victimization) Events Per School.

    Students self report of sexual assault victimization averaged at the school level and adjusted for baseline and number of students. Adjustments made by including baseline measure and number of students as covariates in models. Data will be collected at baseline and annually for 4 years.

    Data will be collected at baseline and annually for 4 years.

Other Outcomes (2)

  • Change in Violence Acceptance

    Data will be collected at baseline and annually for 4 years.

  • Increase in Bystanding Behaviors
