Participation in society is a cornerstone for quality of life, active aging, and aging in place. While the majority of older adults prefer aging in place, health and financial challenges can hinder this vision. Conducted in suburban South Jersey, this study utilized mixed methods, including surveys and interviews with older adult participants. Surveys indicated that satisfaction with participation in the community is influenced by functional ability, healthcare service availability, and information access. Interviewees identified suggestions to overcome barriers (e.g., improve access to community and address ageism). Combined results provide a theory of change which suggests older adults’ empowerment in community participation hinges on home living support, participation options aligning with ability and interest, and accessible information on community events. This person-centered planning approach emphasizes the importance of older adult and stakeholder participation in foundational community planning, offering translational foundational tools for evidence-based strategies to engage them in future community action plans (CAPs).
