The mediating roles of functional limitations and social support on the relationship between vision impairment and depressive symptoms in older adults
Vision impairment is prevalent and it is strongly associated with depressive symptoms in older adults. This study aimed to investigate the mediating roles of functional limitations and social support on the relationship between vision impairment and depressive symptoms in older adults. This study used data from a probability-based sample of 1,093 adults aged 60 and older in Shanghai, China. Structural equation models were used to examine the structural relationships among sets of variables simultaneously, including vision impairment, activities of daily living ADLs, instrumental ADLs (IADLs), friends support, family support, relatives support and depressive symptoms. The bootstrapping method and the program PRODCLIN were used to test the indirect effects of these variables. This study found that vision impairment was directly associated with a higher level of depressive symptoms, and the association was partially mediated by functional limitations (IADLs) and social support (friends support). The study demonstrates that improving social support from friends and enhancing social participation for visually impaired older adults can reduce depressive symptoms. More importantly, this study contributes to the knowledge of mediating mechanisms between vision impairment and depressive symptoms.
