Abstract
According to continuity theory, successful aging is promoted when older people are able to continue familiar activities as a way to maintain self-identity. The purpose of this study was to examine the importance of both external resources provided by Taipei city and older adults' internal resources in internal and external continuity and life satisfaction. The data were from the 2019 Taipei City Senior Citizen Condition Survey acquired through face-to-face interviews. Only the community-based sample without disability was included in the analysis (n = 1494). Structural equation modeling was used for the analysis. Both internal and external resources significantly promoted internal continuity (physical activity, Internet use, and lifelong learning) and external continuity (work, social connectedness, and social participation), and the effects of personal resources were larger. External continuity was positively related to life satisfaction. The effects of external resources on continuity and life satisfaction were stronger in older women than in older men. Age-friendly cities may provide support for activity continuity and promote well-being for older people. Policy suggestions are discussed.
