Mood Lifters for Seniors: Development and Evaluation of an Online, Peer-Led Mental Health Program for Older Adults.

Effective, scalable mental health programs are greatly needed for older adults. In this study, Mood Lifters-a peer-led, community-based program promoting mental well-being-was adapted to more specifically address the needs of older adults. Two groups completed the 14-week program via Zoom. A total of 24 participants enrolled ( M age  = 72 years), with 20 (83%) completing the program. Compared to baseline, program completers showed significant improvements in depression symptoms ( p  < .01), perceived stress ( p  = .04), sleep quality ( p < .01 ), physical activity ( p  < .01), and brain health behaviors ( p  = .01), with improvements maintained at 1-month follow-up. No significant changes were reported in participants' anxiety, loneliness, or resilience. Participant ratings of program satisfaction were very high ( M  = 4.75/5). Results suggest Mood Lifters for Seniors is feasible to disseminate and acceptable to older adults, with preliminary evidence of benefits in several mental health domains. Future randomized trials with larger, more diverse samples are needed to confirm program benefits.
