Peer Volunteers' Journeys Through Training and Engagement in Older Adult Communities: Descriptive Qualitative Study.

Background: The rising prevalence of mental health conditions such as depression and anxiety among the aging population underscores the need for accessible and effective psychosocial support, particularly for community-dwelling older adults who face barriers like social stigma and limited mental health literacy. Peer volunteers have emerged as a promising resource to support these individuals; yet, they often lack the requisite training for effective intervention. Objective: This study aims to explore the experiences of peer volunteers who participated in a Psychological First Aid training program. Methods: Using a descriptive qualitative research design, semistructured interviews were conducted with 13 older adults between September and October 2024, and data were thematically analyzed. Results: Three themes were identified: (1) dimensions of volunteerism from motivations to resistance, (2) empowerment through collaborative learning, and (3) recommendations for designing inclusive, holistic training programs. Conclusions: The findings of this study showed positive outcomes such as personal growth and strengthened social connections among participants. However, enhancements in teaching methods, logistical arrangements, and session regularity are recommended to optimize the Psychological First Aid program. These insights can guide the development of more robust training models to support both peer volunteers and the older adult communities they serve.
