Abstract

Purpose: In the present study, we aimed to examine the total and moderating effects of needs-satisfaction-driven quality-of-life (QoL) measure on age-related change in functional status. Methods: Participants in the Survey of Health and Retirement in Europe (N = 18,781 at Wave 1) completed a measure of QoL (CASP-12) at baseline and reported their functional status across subsequent three waves using activities of daily living (ADL), instrumental activities of daily living (IADL), and functional limitation indices. Results: Growth-curve model estimates revealed that aged individuals with lower QoL scores at baseline had a steeper increase in disability deficits accumulation and functional limitation progression than their counterparts with a higher sense of QoL. The effects were more pronounced in ADL and IADL disability scales in which QoL moderated both linear and quadratic age-related changes. Conclusions: Higher QoL attenuates processes of functional decline in late adulthood. Practitioners may seek strategies for improving and enhancing patients’ QoL, as its salutary effects diffuse beyond psychological experience and include long-term effects on physical functioning.
