The study, published today in JAMA, is the culmination of a large Centers for Disease Control and Prevention clinical trial spanning 20 racially segregated neighborhoods in the Pittsburgh area to evaluate two violence prevention programs. The proportion of youth reporting the use of sexual or partner violence in their relationships decreased in both groups by about 12 percentage points.
