This study aims to empirically verify the mediating effect of social activity participation and the moderated mediating effect of social support in the relationship between depression and life satisfaction in old age. For this purpose, raw data from Lee et al.'s (2020) were re-analyzed. A total of 10,097 subjects were used for the analysis, and data analysis was performed using SPSS 21.0 for Windows and SPSS PROCESS macro 4.2 version. For statistical analysis, Pearson correlation analysis, mediating effect, moderating effect, and moderated mediating effect were analyzed. The main results from the results were as follows: First, depression was negatively correlated with life satisfaction in old age, social activity participation, and social support. Social activity participation and social support was positively correlated with life satisfaction. Second, participation in social activities had a mediating effect in the relationship between depression and life satisfaction. Third, social support significantly moderated the relationship between depression and social activity participation. Fourth, a significant moderating effect of social support was confirmed in the relationship between depression and life satisfaction. Fifth, social support was found to moderate and mediate the effect of depression on life satisfaction through participation in social activities. Finally, based on the above research results, some suggestions were added for education and welfare services for the elderly and for follow-up research.
