CTC has shown to be effective in reducing alcohol use, substance use, antisocial and violent behaviour, improving academic performance, and strengthening protective factors. In addition to these improvements to adolescent health and behaviour outcomes, large US trials of Communities That Care have demonstrated that CTC communities are more likely to adopt and implement evidence based programs compared to control communities.
The below publications provide more detail about the US trials and evidence of the effectiveness of Communities That Care.
