Abstract
This study aims to identify the effects of social participation on depression among adults over 60 years old living alone in Korea, focusing on the mediating effect of health‐related behavior on the social participation–depression relationship. The study relies on secondary data analysis using the 6th wave of the Korea Longitudinal Study of Ageing, and structural equation modeling method was employed for analyses. The findings indicate that older adults’ participation in religious and social gatherings decreases depressive symptoms. The study also finds that regular eating behavior, drinking, and exercise also act as significant mediators, as older adults’ participation in social gatherings is associated with those health‐related behaviors and that they also reduce depression. The results suggest that social participation by older adults who live alone is crucial not only for providing them with support but also for encouraging health‐related activities that can have direct effects on their mental health. Implications for social work practice are also discussed.
