We will pilot test and refine Cuerpo Sano, Mente Sana, our newly enhanced self-management program for depression and chronic medical illness. Following a framework for successful implementation of interventions, we will 1) evaluate intervention context and refine our intervention and implementation strategy; 2) conduct a randomized trial with 30 low-income Spanish-speaking patients with depressive disorder and chronic medical illness; 3) review pilot findings of feasibility, implementation, and potential sustainability with a multistakeholder panel and then revise our materials and procedures; 4) conduct a second trial with 30 additional patients; and 5) review additional pilot findings (including 3- and 6-month intervention effects on self-efficacy, self-care behaviors, and depression and health outcomes and interviews with clinic stakeholders) and finalize the intervention and implementation strategy. This study lays the groundwork for future comparative effectiveness studies of strategies to address depression among Latinos in safety net primary care.
