Prevention Strategies

Youth and community violence are serious problems that can have lasting harmful effects on victims, their families, and entire communities. Prevention of community violence is possible. A strong and growing research base shows that multiple prevention strategies are scientifically proven to reduce violence and associated risk factors.

CDC has summarized the best available evidence in Youth Violence Prevention Resource for Action [4 MB, 64 Pages]. This Resource for Action, formerly known as, “technical package,” represents a select group of strategies to help communities and states sharpen their focus on prevention activities with the greatest potential to prevent youth and community violence and its consequences. The Division of Violence Prevention (DVP) is in the process of updating and expanding this Resource for Action and has developed this summary table with descriptions of newly added examples that meet the criteria for inclusion (i.e., meta-analyses or systematic reviews or rigorous experimental or quasi-experimental* evaluation studies on youth or community violence or on risk and protective factors). The examples provided are not intended to be a comprehensive list of evidence-based programs, policies, or practices for each approach but rather illustrate models that have been shown to decrease youth or community violence victimization or perpetration or have beneficial effects on risk or protective factors for youth or community violence. More in-depth information about the new examples is provided below. Learn more about implementation resources and considerations on Violence Prevention in Practice.

* Quasi-experimental designs are those without random assignment and include a range of designs. Random assignment is not always possible in evaluations of youth and community violence programs, policies, and practices conducted in real-world settings.

Strengthen Economic Supports

Tax credits

Summary: Tax credits for families with children like state and federal Earned Income Tax Credits (EITC), help individuals and families with lower incomes increase their income while incentivizing work. The federal EITC is one example. The amount of the federal EITC varies depending on income earned through work, marital status, and the number of qualifying children. States also have EITCs, which vary in eligibility requirements and funding amounts. State tax credit amounts are usually a percentage of the federal EITC. An analysis of state EITC laws found that implementing a high state EITC was associated with a 10% lower rate of violent crime. EITCs may also have important implications for addressing racial inequities. An analysis of EITC laws over time found that the EITC was associated with a reduction in income gaps among White and Black households in the bottom half of the income distribution. However, these reductions were only observed at the 50th and 25th percentile of the income distribution and not for households with very low incomes. These findings indicate that while EITC may help reduce Black or African American and White household income gaps for some groups, other individual and household economic supports may also be needed to fully address income gaps for households with the lowest incomes.

Strengthen Young People’s Skills

Year Up

Summary: Year Up, a national training program, teaches students in urban communities high-demand technical and professional skills, connects them with employers, and provides college credits through agreements with local colleges. The full-time program provides a range of extensive supports, including weekly stipends to help cover transportation and other program-related expenses. A randomized controlled trial of Year Up found associations between participation in the program and protective factors for youth and community violence, including increases in employment, higher earnings, and reductions in financial hardships.

Summer youth employment programs

Summary: While the focus varies, summer youth employment programs often provide work experience to youth and young adults (up to age 25) with wages paid or supplemented by local government agencies. Programs can also provide adult mentoring and various training related to job preparedness and life skills. Multiple randomized controlled trials (RCTs) find promising effects for violence prevention. While the effects on other outcomes (e.g., academic success and future employment) vary and are often small, effects on violent crime, can be substantial. For example, an RCT in Chicago found a 43% reduction in violent crime over 16 months for high school students in the jobs program relative to those in the control condition. A similar study in Boston found a 35% reduction in violent crime during the 17 months after youth participated in a summer youth employment program.

Create Protective Community Environments

School restorative justice programs

Summary: School restorative justice (RJ) programs build relationships to resolve conflict and avoid harm instead of suspending or expelling students.  RJ programs and practices (like peer mediation) are usually implemented as an alternative to traditional policies that are punishment-focused and remove or exclude students from their usual educational settings (like zero-tolerance policies). RJ includes formal and informal practices that help students repair harm, improve relationships, and teach students how to work together in proactive, respectful ways to constructively resolve conflicts. A systematic review of 34 studies, including 6 randomized controlled trials and one quasi-experimental study, found that restorative practices are associated with a range of benefits relative to traditional discipline practices, including lower rates of aggression and bullying, as well as fewer suspensions and expulsions. Restorative justice programs have the potential to reduce the racial and ethnic inequities and harmful consequences of zero-tolerance policies.

Compulsory education laws

Summary: Compulsory education laws require children to attend school until they reach a certain age. State laws vary regarding the minimum age for students to leave school. Studies using quasi-experimental approaches to compare crime rates across locations with varying policies find that a higher minimum age for a student to leave school (from 16 to 18 years old) is associated with lower rates of youth community crime and violence. For example, one study found that compulsory education is associated with a 23% lower violent crime arrest rate for males in this age group. Some evidence suggests that raising the minimum age to leave school may have an even greater effect on crime in communities with larger proportions of Black or African American residents. Other evidence suggests that a higher minimum dropout age may increase some school-related risks of victimization among females and younger students. Overall, it is important to consider the supports that are available to older adolescents and younger students in school to reduce the potential for victimization and promote positive behavior and academic success (e.g., restorative justice, skills training).

Chicago Safe Passage

Summary: Chicago Safe Passage provides students safe routes to and from school by placing highly visible community members along these routes to monitor and assist with students’ safe travel. Community members are hired as safe passage workers, also referred to as guards, and their role is to be physically present on routes students usually take to and from school. Safe passage workers are trained on conflict de-escalation strategies and have reporting protocols for violent behavior. Studies using quasi-experimental methods that compare differences in crime before and after implementation indicate that, in addition to benefits for school attendance, the program is associated with significant reductions in overall crime in monitored areas relative to non-monitored areas, including 14% to 18% lower rates of violent crimes.
