Scaling New Hope: A MOST Trial to Optimize Provider Training for Indigenous Youth

Research Aims and Hypotheses: American Indian/Alaska Native (AI/AN) youth face the highest suicide rates in the United States, a crisis rooted in historical trauma and systemic inequities. While our team has proven that "New Hope" culturally adapted, brief intervention significantly reduces suicide ideation, attempts, and deaths among youth and young adults (ages 10-29), a critical gap remains in how to effectively train the community-based workforce to deliver it at scale. The primary aim of this study is to use a Multiphase Optimization Strategy (MOST) approach to determine the most effective and efficient training strategy for New Hope. We hypothesize that scalable, "lighter-touch" training methods (virtual training and peer consultation) will be just as effective (non-inferior) as resource-intensive methods (in-person training and expert coaching) in ensuring provider competency and reducing youth suicide risk.
