Cure Violence shows it can be effective to treat violence using a health approach – i.e. to treat it as a contagion rather than as a problem of bad people. The intervention relies heavily on peer influencers and norm appeals. It has had multiple independent evaluations – all showing large statistically significant reductions in violence.
Note: To minimize site maintenance costs, all case studies on this site are written in the past tense, even if they are ongoing as is the case with this particular program.
Cure Violence was developed in 2000 by Gary Slutkin, M.D., an epidemiologist at the University of Illinois at Chicago’s School of Public Health. Launched in West Garfield, which at that time was Chicago’s most violent community, the approach reduced shootings by 67% in its first year and by 42% over three years.
In 2004, it expanded to 15 communities and homicides in Chicago dropped by 25%. The program name was changed to Cure Violence in 2012, and by the end of 2015 it was being implemented in 23 cities in North and Central America.
Returning to Chicago after working in Africa, epidemiologist Gary Slutkin was shocked by the city’s relatively high crime rate. He noticed three similarities with the epidemics he had previously been working with: (1) they clustered in particular times and places, (2) they self-replicated - one incident led to another, and (3) they increased in waves. He wondered if similar mitigation approaches might work. That meant treating violence as a contagion that infected people, rather than a problem with bad people.
While working to stop the spread of TB in the US, and then the spread of AIDS and cholera in Africa, he learned that people were most receptive to advice delivered by peers.
Prioritizing Audiences
The program focused on those currently involved in violence or at very high risk for involvement in violence.
Cure Violence used three main strategies to prevent violence:
Using a health approach to reduce the risk of “infection”, and recognizing the importance of communicating through peer networks, the program hired peers from each community to change behaviors and norm and intervene in disputes. Outreach Workers and “Violence Interrupters” were employed and trained to identify high-risk situations and persons by patrolling specific neighbourhoods and utilizing their existing networks. They then intervened before disagreements escalated into violence and worked with the highest risk to change behaviors and norms. (Neighbourhood Coaches and Block Leaders, Norm Appeals, Word of Mouth)
Violence Interrupters and Outreach Workers used their street credibility to change behaviors and interrupt conflicts. They also modeled and taught community members better ways of communicating with each other and how to resolve conflicts peacefully.
1. Detect and interrupt potentially violent conflicts
Trained violence interrupters and outreach workers prevented shootings by identifying and mediating potentially lethal conflicts in the community, and following up to ensure that the conflict did not reignite.
2. Identify, treat and foster behavior change among those at highest risk
Trained, culturally-appropriate outreach workers worked with the highest risk community members to make them less likely to commit violence, by meeting them where they were, talking to them about the costs of using violence, and helping them to obtain the social services they needed – such as job training and drug treatment.
These workers were trained in methods of persuasion, alternatives to violence, detection and diagnosis of violent behavior, appropriate referrals for client issues, as well as a number of other areas and learn the methods that could be used to encourage new positive behaviors such as conveying new information, teaching new skills applicable to the new behaviors, practicing, developing opportunities for positive peer reactions, and avoiding negative peer reaction. The program tried to maintain relationships with all of the city’s gangs and violent cliques.
3. Mobilize the community to change norms.
Workers engaged leaders in the community as well as community residents, local business owners, faith leaders, service providers, and the high risk, conveying the message that the residents, groups, and the community did not support the use of violence. (Norm Appeals)
By 2018, The Cure Violence Health model had been implemented in large cities such as New York City, Chicago, Baltimore, San Antonio and New Orleans, and also in smaller cities like Kansas City, Syracuse and Albany, and all over the world – from San Pedro Sula, Honduras to Cape Town, South Africa.
In 2018, Cure violence received $5.4 million funding in Chicago (from state and city police budgets) and $17.2 in New York. Across the US, programs received about $40 million in funding.
The program emphasized continual data collection and monitoring. Program success was measured using the rates of reported crimes and violent injuries.
In May 2008, Dr. Wesley G. Skogan, at Northwestern University, completed a three-year, independent, Department of Justice-funded report finding large reductions in violence attributable to the program. There have been more than a dozen additional studies showing similar effects. Additionally, in Chicago in 2015 and 2016, budget cuts and subsequent budget reinstatement provided a reversal design opportunity to see the impacts on the city’s crime rates.
The Cure for Violence Health Model has since had multiple independent evaluations showing large statistically significant reductions in violence.
Chicago
When first introduced in Chicago, the approach reduced shootings by 67% in its first year and by 16-34% over three years. In 2004, it expanded to 15 communities and homicides in Chicago dropped by 25%. A 2009 NIJ/Northwestern University evaluation analyzed seven communities in Chicago over three years. It found that the program reduced shootings and killings by 41% to 73%, with retaliatory shootings eliminated in five of seven communities examined. During 2015 budget cuts eliminated program workers in 13 of 14 communities; homicides began increasing within a month and the following year was Chicago’s deadliest in nearly two decades. In the one community where it continued, violence continued to go down. In 2017 funding was restored and murders dropped by 16%.
Baltimore
A 2012 CDC/Johns Hopkins evaluation of 4 communities in Baltimore credited the program with reducing shootings and killings by up to 34-56%. Community norms were influenced, even with those who did not directly participate in the program, and the reductions in violence spread to surrounding communities as well.
New York
New York ‘s program yielded a 37% to 50% reduction in gun injuries in two communities; a 63% reduction in shootings in one community; a 14% reduction in attitudes supporting violence, with no change in controls; and an 18% reduction in killings across 13 program sites while matched controls had a 69% increase (2004-2013).
Philadelphia
In Philadelphia, a 2017 evaluation found a 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.

Lesson Learned
Violence can be treated effectively using a health approach– i.e. treated as a contagion rather than as a problem with bad people.
