Functional limitations and mental well-being among frail older adults: the mediating effect of social relationships.
Objectives: Physical functional limitations come with aging that impact social relationships and participation (SRP). This study aimed to investigate whether SRP mediates the association between functional limitations and MWB in frail older adults.
Method: We used survey data collected from 338 frail older adults in Norway between 2017 and 2019. Older adult's functional limitation was measured by activities of daily living (ADL). Linear regressions were used to estimate the effect of ADL and SRP on MWB, and the effect of ADL on SRP. A structural equation model (SEM) was used to decompose the total effect of ADL on MWB into direct and indirect (via SRP) effects.
Results: We found that both ADL and SRP significantly predicted MWB. The effect of ADL on SRP was also statistically significant (β = 0.265; p < 0.01). The direct effect of ADL was higher (β = 0.763; p < 0.01) than its indirect effect (β = 0.383; p < 0.01). The proportion of the total effect that is mediated was about 34%. Analyses from the longitudinal framework showed similar results.
Conclusion: Healthy aging can improve MWB directly or indirectly through better SRP. Our findings may have important implications for the design of health policies for older adults by further focusing on maintaining and investing in SRP.
期刊介绍：
Aging & Mental Health provides a leading international forum for the rapidly expanding field which investigates the relationship between the aging process and mental health. The journal addresses the mental changes associated with normal and abnormal or pathological aging, as well as the psychological and psychiatric problems of the aging population. The journal also has a strong commitment to interdisciplinary and innovative approaches that explore new topics and methods.
Aging & Mental Health covers the biological, psychological and social aspects of aging as they relate to mental health. In particular it encourages an integrated approach for examining various biopsychosocial processes and etiological factors associated with psychological changes in the elderly. It also emphasizes the various strategies, therapies and services which may be directed at improving the mental health of the elderly and their families. In this way the journal promotes a strong alliance among the theoretical, experimental and applied sciences across a range of issues affecting mental health and aging. The emphasis of the journal is on rigorous quantitative, and qualitative, research and, high quality innovative studies on emerging topics.
