Abstract

Background: Physical limitations may hinder older adults with physical disabilities' capability to perform various activities, which can affect their quality of life (QOL). Accomplishing meaningful activities may mitigate the impact of limited activity performance on their QOL. This longitudinal study aims to investigate how activity meaning mediates the relationship between activity performance and QOL among older adults with disabilities.

Methods: Data for this longitudinal study was collected from 813 community-dwelling older adults aged 60 and above who had physical disabilities, over a two year interval. Path analysis was used to examine the cross-sectional and longitudinal mediation effects from activity performance, through activity meaning, to QOL.

Results: At the same wave, high IADL performance or social activity performance, and high QOL was indirectly associated through high IADL meaning or social meaning. As for longitudinal association, high T1 IADL performance was associated with better T2 QOL through high T1 and T2 IADL meaning. Similarly, high T1 social activity performance also contributed to T2 QOL through high T1 and T2 social activity meaning. Additionally, social activity performance exhibited higher influence on QOL than that of IADL.

Conclusions: Both IADL and social activities have distinct impacts on the QOL of older adults with disabilities. To improve the current and future QOL of older adults with disabilities, professionals must prioritize their involvement in the most meaningful activities while being sensitive to and supportive of their preferences and valued lifestyles.
