Brief Project Overview and Impact To address the elevated rates of substance use and suicide risk among AI/AN youth in Michigan, this project introduces an innovative, community-driven care model designed to build sustainable prevention capacity. This will be achieved by developing Communities of Practice focused on suicide and substance use prevention and by adapting and implementing PC CARES-ASU (Promoting Community Conversations About Research to End Suicide and At-risk Substance Use). Originally designed and implemented in remote communities in Northwest and Southwest Alaska, PC CARES has been successfully implemented in indigenous communities, demonstrating its effectiveness in increasing prevention knowledge, preventative health behaviors, and community engagement. Unlike traditional behavioral health interventions that rely on external service providers, this model is community-led, peer-driven, and designed for long-term sustainability. By training local facilitators, this project embeds prevention education within the community, expands opportunities for workforce development, and ensures that knowledge and skills are retained and continually expanded. It also strengthens multi-sector collaboration among community members, behavioral health professionals, and educators, to integrate prevention strategies into everyday settings. Recently recognized on the Suicide Prevention Best Practices Registry, PC CARES empowers trusted adults and community organizations to support youth wellness proactively. This scalable and adaptable model represents an innovative shift in care delivery, moving away from traditional clinical frameworks toward a sustainable, community-empowered prevention approach. Through Learning Circles, participants will discuss bite-size pieces of research and apply evidence-based strategies in practical ways to strengthen suicide and substance use prevention efforts. In the short term, this project will increase community engagement, strengthen knowledge of protective factors, and expand access to prevention resources. Over time, trained local facilitators will continue leading Learning Circles in their communities, contributing to sustained suicide and substance use prevention efforts. The project will help reduce risk behaviors among AI/AN youth by expanding access to culturally relevant support systems including parents, grandparents, aunts, uncles, teachers, coaches, and mentors. By demonstrating its effectiveness in Michigan tribal communities, this model could serve as a framework for broader regional or national implementation of sustainable, community-led prevention initiatives.
