Description

The Comprehensive Gang Prevention, Intervention, and Suppression Model (referred to herein as the Comprehensive Gang Model) is based on a nationwide assessment of youth gang problems and programs, funded by the federal Office of Juvenile Justice and Delinquency Prevention (OJJDP). Conducted in the late 1980s, this study identified the main strategies that are commonly used and viewed favorably in community responses to gang problems. These strategies have been further developed and interrelated in the OJJDP Comprehensive Gang Model. Brief descriptions of the five strategies follow.

Community Mobilization: Involvement of local citizens—including former gang youth, community groups, and agencies—and the coordination of programs and staff functions within and across agencies.

Opportunities Provision: The development of a variety of specific education, training, and employment programs targeting gang-involved youth.

Social Intervention: Involving youth-serving agencies, schools, grassroots groups, faith-based organizations, law enforcement, and other juvenile/criminal justice organizations in “reaching out” to gang-involved youth and their families and linking them with the conventional world and needed services.

Suppression: Formal and informal social control procedures, including close supervision and monitoring of gang-involved youth by agencies of the juvenile/criminal justice system and also by community-based agencies, schools, and grassroots groups.

Organizational Change and Development: Development and implementation of policies and procedures that result in the most effective use of available and potential resources, within and across agencies, to better address the gang problem.

  • The Comprehensive Gang Prevention, Intervention, and Suppression Model has demonstrated effectiveness in multiple cities.
  • Researchers looked at six cities in the initial evaluation of the model; they compared youth and neighborhoods that received Comprehensive Gang Model programming with matched comparison groups of youth and neighborhoods that did not receive the programming. They found that the program was implemented with high fidelity in three of six sites (Chicago, IL, Riverside, CA, and Mesa, AZ). In these three sites, there were statistically significant reductions in gang violence, and in two of these sites, there were statistically significant reductions in drug-related offenses when compared with the control groups of youth and neighborhoods.
  • In a later evaluation of an adaption of the Comprehensive Gang Model in Los Angeles, CA the Gang Reduction Program, researchers concluded the program was effectively implemented to combat “traditional,” multigenerational, urban territorial gangs, and that the strongest concentrations of violent crime, or “hot spots,” diminished with statistical significance following CGM implementation.

In sum, the Comprehensive Gang Model has demonstrated evidence of its effectiveness in reducing gang violence when implemented with good program fidelity. Although the research to date has been primarily on the intervention and suppression components, the Comprehensive Gang Model holds promise for integrating prevention activities with intervention programs and suppression strategies.
