This study was a randomized controlled trial of a dating violence and sexual harassment (DV/H) prevention program called the Shifting Boundaries (SB) Program. Thirty-five public middle schools in New York City were randomly assigned to one of four treatment conditions of the SB program. The project includes a baseline and two follow-up surveys with 6th, 7th and 8th grade students to assess short to medium term impact on rates of DV/H. The classroom curriculum intervention (SBC) covered the consequences for perpetrators of DV/H, state laws and penalties for DV/H, and respectful relationships. The school (building-level) intervention (SBS) included the use of school-based restraining orders, higher levels of faculty and security presence in areas identified through student mapping of safe/unsafe "hot spots," and the use of posters to increase awareness and reporting of DV/H. The project examined (1) the effects of saturating a school environment by providing the SB intervention to all three middle school grades compared to only two grades or one grade and (2) the effects of two dosages of SB across two years compared to one dosage of the SB intervention across one year which was explored in two prior evaluations of the program.
