Dr. Brittany Cooper and Dr. Laura Hill are PIs on a state project to examine the implementation and effectiveness of CPWI. Washington State Division of Behavioral Health and Recovery (DBHR) initiated CPWI in 2011 to reduce underage substance use among adolescents. CPWI is a strategic, data-informed, community coalition model aimed at preventing youth alcohol and drug use by targeting prevention efforts in the highest risk communities throughout the state. CPWI utilizes a comprehensive, multicomponent, and multilevel framework to reduce risk factors in individual, peer, family, school and community domains. Currently, there are 64 communities in various stages in the CPWI process.
