What We Do

This preventive intervention study examines the impact on lowering violence perpetration and victimization in middle school. It analyzes data from a multisite longitudinal random assignment (of 36 schools) which focused on 9000 middle-school children, and compares a universal or whole-population approach and a selective or high-risk group focused approach. Data collection is complete and the data set is available for normative developmental analyses, intervention impact modeling, and related questions of population effects.
