The overall goal of this study is to develop an effective and potentially scalable intervention to prevent diabetes in people with elevated mental health symptoms (EMS) and prediabetes. This study focuses on Latinos, a demographic group at particularly high risk for these related conditions. Experience from the Diabetes Prevention Program (DPP), and related translational studies, suggests that the evidence-based DPP lifestyle intervention is less effective among depressed individuals. The proposed Promotora Intervention for Metabolic and Mental Health (PRIME2) will be the first adaptation of the DPP lifestyle intervention to simultaneously address mental health and prediabetes in a program delivered by promotoras, or community health workers.
