Abstract

This study aimed to verify the longitudinal mediating effect of depression and perceived social support in the relationship between loneliness and life satisfaction during the COVID-19 Pandemic period. The first survey was conducted from February 19 to March 3, 2021, and the second survey was conducted from October 19 to November 17, 2021. First, depression was found to mediate the relationship between loneliness and life satisfaction. Second, depression and perceived social support showed a double mediating effect in the relationship between loneliness and life satisfaction. Third, the path through which loneliness directly affects life satisfaction was not significant, and it was confirmed that loneliness had a significant effect on life satisfaction through depression and perceived social support. This is expected to contribute to increasing individual’s lower life satisfaction by considering the characteristics of depression and perceived social support in conducting interventions for individuals who experienced loneliness during the COVID-19 period.
