Older adults are a growing proportion of the United States population, and older adulthood is a period that includes a variety of life changes (e.g., social, physical, cognitive). My dissertation study aims to explore the longitudinal impact of a two-session group Acceptance and Commitment Training workshop on psychological well-being outcomes in healthy community-dwelling older adults. Individuals, families, and communities all stand to benefit from interventions that may improve well-being in this population.
