Effectiveness of Universal School-Based Programs to Prevent Violent and Aggressive Behavior : A Systematic Review

Universal, school-based programs, intended to prevent violent behavior, have been used at all grade levels from pre-kindergarten through high school. These programs may be targeted to schools in a high-risk area—defined by low socioeconomic status or high crime rate—and to selected grades as well. All children in those grades receive the programs in their own classrooms, not in special pull-out sessions. According to the criteria of the systematic review methods developed for the Guide to Community Preventive Services (Community Guide), there is strong evidence that universal, school-based programs decrease rates of violence among school-aged children and youth. Program effects were consistent at all grade levels. An independent, recently updated meta-analysis of school-based programs confirms and supplements the Community Guide findings.
