In this report we present the results of an experimental evaluation based on a randomized
controlled trial (RCT) of a dating violence and sexual harassment (DV/H) prevention program -
called the Shifting Boundaries (SB) Program. We randomly assigned 23 public middle schools in
New York City to one of four treatment conditions of SB varying by dosage and saturation
levels. 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 intervention we tested
had two main components. First, we had an SB classroom curriculum (SBC), covering the
consequences for perpetrators of DV/H, laws and penalties for DV/H, and respectful
relationships. Second, we had an SB school (building-level) (SBS) component which 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,"
