OBJECTIVES: Literature on the costs of community support programs is scant. Beat the Blues (BTB) is a home support program for depression which involves trained social workers who meet with participants to identify care management concerns, make referrals and linkages, provide depression education, develop tailored action plans to accomplish identified behavioral goals and enhance engagement in pleasurable activities, and teach stress reduction techniques for managing daily stressors (e.g., deep breathing). The primary objective of this study is to assess the cost of implementing BTB in African American elders with depressive symptoms. METHODS: The cost analysis is piggybacked onto the parent BTB trial, which employs randomized two-group experimental design (treatment vs. control). Candidates are screened twice for depressive symptoms (PHQ-9 score >5) to determine eligibility.  Participants are randomly assigned to intervention or waitlist control. BTB is administered over 4 months with assessments in both groups at baseline and 4-months. Cost components comprise 4 main categories (Screening, Intervention Delivery, Supervision, and Other).  Senior center management and social workers (interventionists) kept detailed logs of time spent conducting each component. The cost of conducting the intervention was calculated as the time spent performing each task multiplied by wage rate of the individual who performed the task. Non-time related cost (material and mileage) was also calculated. RESULTS: A total of 166 participants received the intervention. Average cost of BTB was $342 per person.  The most costly aspect of BTB per person was cost of program delivery ($275), followed by materials ($48).The least costly aspect of the intervention was time spent supervising interventionists ($9). CONCLUSIONS: This study informs decision makers about the resources required for depression community support interventions, which are not typically reimbursable through private or public healthcare programs. Results can also inform decision making regarding the costs of such interventions in relation to pharmacological treatments.
