This study identified the direct effect of social support on depression and life satisfaction in the elderly and the mediating effect on life satisfaction through depression. The subjects of analysis were seniors aged 65 years or older, and the 6th year supplementary survey data and 7th year main survey data of the National Old Age Security Panel Data were used. The analysis method used Baron and Keney's analysis method for multiple regression analysis and mediation effect analysis, and then verified significance through the Sobel test. To summarize the research results, first, emotional support and material support were found to have a direct effect on depression. Second, emotional support, informational support, and material support had a direct effect on life satisfaction. Lastly, in social support, only emotional support was found to have a partial mediating effect on life satisfaction through depression. Based on the research results, policy and practical suggestions that can improve life satisfaction by alleviating depression by strengthening emotional support for the elderly were discussed.
