Community Violence Intervention

Through a combination of street outreach by credible messengers and behavioral science-informed interventions, community violence intervention (CVI) programs help de-escalate stressful situations before they lead to violence.

The vast majority of gun homicides in America result from arguments that spiral out of control and turn deadly when a gun is present. That’s why CVI programs, such as behavioral science-informed interventions, can significantly reduce violence involvement by helping people cope with untreated trauma and learn to de-escalate conflicts. Given how little we know about alternative responses to gun violence — and the very high costs this violence imposes on our most vulnerable communities — this promise provides a clear rationale to continue studying the CVI model.

The Crime Lab conducts rigorous evaluations of CVI programs and works to find ways to make them even more effective at reaching the individuals at greatest risk of violence, providing the right supports to improve outcomes, and scaling those successes.
