Cure Violence — Chicago

University of Illinois at Chicago / Chicago Department of Public Health · Chicago, USA · 2000

Summary

Cure Violence treats gun violence as a contagious disease, using credible messengers to interrupt transmission before shootings cascade. The Chicago evaluation found meaningful reductions in several communities but not all, and the quasi-experimental design limits causal claims. Subsequent evaluations in Baltimore, Philadelphia, and internationally have produced mixed results. The program is notable for reconceptualizing violence prevention entirely—from criminal justice to public health—and for demonstrating that people with direct experience of violence can be effective interveners. The evidence base is promising but not definitive, making Cure Violence a model case for how to evaluate complex community interventions.

Research question

"Does a public health approach to violence—using outreach workers to interrupt conflicts and change norms—reduce shootings?"

Methodology

Intervention

Trained outreach workers (credible messengers, often with prior criminal records) intervene in conflicts before they escalate; community norm-change activities

Assignment

Quasi-experimental (matched comparison neighborhoods)

Sample size

Seven Chicago communities (treatment and matched controls)

Primary outcome

Shootings; homicides; shooting trends relative to comparison areas

Effect estimate

Shooting reductions of 16–28% in treated communities; statistically significant in 4 of 7 sites; homicide trends improved relative to controls

Decision

Program expanded nationally and internationally; subsequent RCTs in Trinidad and Tobago found positive results; design adopted in 50+ cities globally

Result

Mixed

Shooting reductions of 16–28% in treated communities; statistically significant in 4 of 7 sites; homicide trends improved relative to controls

Evidence strength

Moderate

Quasi-experimental design; causal interpretation requires care.

Replication status

Partially replicated
