Abstract
Age-related physiological and cognitive changes significantly affect older adults' participation in day-to-day functioning. This interview study aimed to uncover and illuminate the intricate dynamics between individuals' responses to aging restrictions and day-to-day functioning, and how they relate to successful aging. We used a qualitative research design to explore the various responses to aging decline and their implications for daily functioning among older adults. Eighteen in-depth interviews were conducted with older adults, focusing on their occupational characteristics, needs, and responses to aging constraints. The transcripts were analyzed using principles of constructivist grounded theory. Three main categories were identified regarding older adults' responses to the decline in abilities that come with age: (a) acceptance, reflecting the individual's ability to adapt to the age-related changes and constraints; (b) personal resources, including a positive mindset and self-efficacy; and (c) coping strategies, including meaningful roles and occupational adaptation. This study's findings indicate three types of responses to aging restrictions that may contribute to greater engagement in daily life and, consequently, be a key to successful aging. Developing individually tailored interventions that focus on occupational adaptations according to individual needs and preferences is vital in helping older adults maintain their daily functioning and quality of life.
