This study used a quasi‐experimental design to evaluate the efficacy of Chicago's Group Violence Reduction Strategy (VRS), a gun violence reduction program that delivers a focused‐deterrence and legitimacy‐based message to gang factions through a series of hour‐long “call‐ins.”
The findings indicate that those gang factions who attended a VRS call‐in experienced a 23-percent reduction in overall shooting behavior and a 32- percent reduction in gunshot victimization in the year after treatment compared with similar factions. Gun violence in U.S. cities often is concentrated in small geographic areas and in small networks of group- or gang‐involved individuals. The results of this study suggest that focused intervention efforts such as VRS can produce significant reductions in gun violence, especially gunshot victimization among gangs. Focused programs such as these offer an important alternative to broad, sweeping practices or policies that might otherwise expand the use of the criminal justice system. (publisher abstract modified)
