CTC Youth Survey

The Community Youth Development Study reports youths from CTC communities were 25% to 33% less likely to have health and behavior problems than youths from control communities.

Proven Results

Communities That Care was tested in a randomized controlled trial. 24 communities across 7 states were matched in pairs within state and randomly assigned to either receive CTC or serve as control communities.

In this trial, a panel of 4407 students from CTC and control communities was followed and surveyed annually from Grade 5. By the spring of Grade 8, significantly fewer of the panel students from the CTC communities had health and behavior problems than those from the control communities.

Panel students from CTC communities were:

25% less likely to have initiated delinquent behavior
32% less likely to have initiated the use of alcohol
33% less likely to have initiated cigarette use than control community youths

These significant effects were sustained through Grade 10, one year after the intervention phase of the trial ended. By the end of Grade 10, panel students from CTC communities also had 25% lower odds of engaging in violent behavior in the past year than those from control communities.

 

Research shows that communities successfully installed CTC

In this randomized trial, CTC communities implemented over 90% of the core components of the CTC system over multiple years. Key leaders in CTC communities were significantly more likely to adopt a science-based approach to prevention. CTC coalitions faithfully implemented more evidence-based programs than control communities and achieved over 90% fidelity with respect to adherence to stated program objectives, core components, and dosage. These evidence based programs served more children, youth, and parents in CTC communities compared to control communities.

 

Replicated findings

An independent quasi-experimental trial of CTC involving over 100 Pennsylvania communities also found that CTC was effective in reducing delinquency and improving academic performance among youth…» Download report

 

Research shows CTC promotes youth well-being by strengthening protection

By the end of Grade 8, panel youths from CTC communities reported higher levels than controls of all the protective factors that support positive youth development identified in the social development strategy. Social skills, interaction with prosocial peers, school recognition for prosocial involvement, and community opportunities for prosocial involvement were significantly improved among CTC panel youth.

 

Research shows CTC is a good investment

CTC’s significant effects on youth health and behavior problems produce long-term economic benefits. For every dollar invested in CTC, $5.31 is returned in the form of lower criminal justice system, crime victim, and health care costs, and increased earnings and tax revenues.
