Abstract: The Community Prevention and Wellness Initiative (CPWI) is a strategic, data-informed, community coalition-based planning framework for preventing adolescent alcohol use and related risk factors. This study aims to achieve two objectives: 1) evaluate the effectiveness of CPWI in reducing adolescent alcohol use and related risk factor using propensity score-adjusted multilevel modeling; and 2) demonstrate how the CPWI framework integrates the necessary conditions of the collective impact framework for enhancing the impact of community-led initiatives. The sample consisted of 10,794 students from 18 CPWI communities and 84,955 students from 155 comparison communities. Results indicate that CPWI communities had significantly greater reductions in all four alcohol use outcomes and two peer-individual risk factors than comparison communities. CPWI is a promising framework for reducing adolescent alcohol use and some risk factors. Our study also contributes to the limited literature showing the effectiveness of collective impact initiatives using a strong quasi-experimental design.
