An Evidence-Based Program

In today’s data driven world, communities demand evidence-based program that have been proven successful through rigorous, independent, scientific evaluations. The Cure Violence Health Model has multiple independent evaluations – all showing large statistically significant reductions in violence. And more evaluations are currently being conducted.

Below are the current independent evaluations of the Cure Violence model:


New York Evaluations (NYC-Cure) – John Jay Research & Evaluation Center

John Jay College of Criminal Justice Research and Evaluation Center has conducted an extensive, independent evaluation of the Cure Violence program in New York City with support from the Mayor’s Office of Criminal Justice, the city’s Department of Health and Mental Hygiene, the New York City Council, New York State’s Division of Criminal Justice Services, and the Robert Wood Johnson Foundation.

Highlights

  • 37% to 50% reduction in gun injuries in two communities
  • 63% reduction in shootings in one community
  • 14% reduction in attitudes supporting violence, with no change in controls
  • Increased confidence in police and increased willingness to contact police
  • 18% reduction in killings across 13 Cure Violence sites, while matched controls had a 69% increase (2004-2013)

Philadelphia Evaluation – NIJ/Temple University/John Jay

A 2017 evaluation of the Cure Violence program in Philadelphia found significant reductions in violence associated with the program.

Highlights

  • 30% reduction in shootings (comparing the 24 months before the implementation of CeaseFire to the 24 months after implementation)
  • In the five hotspot areas, CeaseFire was associated with a statistically significant reduction in both total shootings (victims of all ages) and shootings of individuals between the ages of 10 and 35.
  • Although in some models comparison groups also showed reductions in shootings, these reductions were either not statistically significant or not as large as those in the CeaseFire target areas.

Baltimore Evaluation – CDC/Johns Hopkins

A 2012 CDC/Johns Hopkins evaluation of 4 communities in Baltimore.

Highlights

  • 56% reductions in killings and 34% in shootings in one community
  • Reductions across all 4 communities
  • 276 conflict mediations
  • Reductions spread to surrounding communities
  • 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.

Chicago Evaluation – NIJ/Northwestern*

A 2009 NIJ/Northwestern University evaluation analyzed 7 communities in Chicago.

Highlights

  • 41% to 73% reductions in shootings
  • 40% reduction/cooling of hot spots
  • 100% reductions in retaliation homicides in 5 of 8 communities
  • “Overall, the impact of the [Cure Violence] Program is significant and moderate-to-large in size.”
  • “In every program area there was a substantial decline in the median density of shootings following the introduction of [Cure Violence].”

Simulation Study – UC Davis Violence Prevention Research Program, Columbia University’s Mailman School of Public Health, and University at Albany

A simulation study was conducted based on aggregated data to simulate violent victimization of a representative sample of 5% of NYC’s population and police force to determine the effectiveness of Cure Violence, hot-spot police interventions and the combination over a 30-year period.

Highlights:

  • 13% reduction in violent victimization seen with the implementation of Cure Violence only
  • Two violence interrupters and one outreach worker would contribute to a 24% reduction in homicide rate; compared to a 150% increase in police force for 20 years to achieve the same result
  • Cure Violence and hot-spots policing together shows a reduction in violent victimization by 19%

Chicago Evaluation – McCormick Foundation/University of Chicago/UIC*

A 2013 McCormick Foundation/University of Chicago/UIC quantitative and a qualitative evaluation of the 2012/2013 Cure Violence Illinois covered two Chicago neighborhoods.

Highlights

  • 31% greater decrease in killings
  • 1% greater decrease in total violent crimes (including domestic violence),
  • 19% greater decrease in shootings
  • Cure Violence high-risk participants reported decreased involvement in crime and violence,

New York Evaluation – BJA/Center for Court Innovation

In New York City, a 2010 BJA/Center for Court Innovation evaluation analyzed the program in Crown Heights, Brooklyn.

Highlights

  • 20% lower shootings compared to control
  • More than 100 mediations involving more than 1,000 people
  • Average monthly shooting rates decreased by 6%, while increasing in the three comparison areas between 18% and 28%
