Researchers are evaluating the effectiveness of a simplified Behavioral Activation program called "Do More, Feel Better" (DMFB), delivered by trained lay volunteers, compared to Behavioral Activation delivered by master's level clinicians. The study focuses on older adults aged 60 and above who attend senior centers and have depression as identified by specific depression rating scales. The goal is to see if the volunteer-delivered intervention can improve activity levels and reduce depression symptoms as effectively as clinician-delivered care, while also exploring treatment satisfaction, overall functioning, and factors affecting intervention fidelity and sustainability. Participants will be randomly assigned to receive Behavioral Activation either from trained volunteers or from master's level clinicians. Both interventions aim to guide clients in reengaging with pleasant and rewarding daily activities to reduce depressive symptoms. The study will be conducted at 18 senior centers across Seattle, New York City, and Tampa. Volunteer and clinician participants must meet educational and language criteria and provide consent for study procedures including session recordings for supervision. During the study, participants will be assessed at multiple time points up to 36 weeks after treatment begins. Researchers will measure changes in depression using the Hamilton Rating Scale for Depression (HAM-D) and changes in activity levels using the Behavioral Activation Scale (BADS). Additional evaluations include cognitive screening, treatment adherence, and client satisfaction. The study will monitor safety and examine long-term outcomes, delivery costs, and factors that affect the quality and sustainability of the interventions.
