Scientific Evaluations / Baltimore Evaluation

A Center for Disease Control funded evaluation conducted by Johns Hopkins University showed statistically significant results across all four communities, reductions in shootings and killings of 34% to 56%, and evidence of norm change.

Implementation Highlights

• Implemented in 4 of the most violent communities in Baltimore
• 276 conflict mediations
• Most participants saw their outreach worker 3 or more times per week

Outcome Highlights

• Significant reductions in shootings or homicides in all four communities – between 34% and 56%
• Communities with triple the amount of mediations had better results
• Norms on violence were changed – People in program site were much less likely to accept the use of a gun to settle a dispute; 4 times more likely to show little or no support for gun use.
• Norm change occurred even with non-clients.
• Reductions spread to surrounding communities
