Guided by the Communicative Ecology Model of Successful Aging (CEMSA), we conducted an interview study with 25 older adult volunteers ( M = 71.8 years old, SD = 5.19) to explore how they discursively negotiated their identities and communicated about volunteering during the aging process. The conventional view of old age and aging tends to be negative, however, our findings from the older adult volunteers’ accounts revealed positive themes regarding their self-categorization and volunteering experiences. These themes include: (a) positive representations of self and other older adult volunteers, (b) transcendence of negative perceptions of old age and aging through volunteering involvement, and (c) communication about engaging in selection, optimization, and compensation in managing volunteer work. Our findings carry significant theoretical and practical implications, underscoring how positive self-categorization and adaptive management of volunteering remarkably contribute to building an ecology of successful aging.
