Youth violence in Latin America and the Caribbean is a big problem, but how well do we understand it? Richard Miles talks to Dr. Patricia Campie, an expert who was commissioned by USAID to find out which violence prevention interventions in the region worked, and which didn’t. She found that parenting and after school programs worked well, but other interventions had very mixed results. You can read about many other findings in the full report, What Works to Prevent Lethal Youth Violence in the LAC Region: A Global Review of the Research.
