Aims of this research are as follows. The first is to find out the level of depression according to the types of retirement. The second is to divide the level of satisfaction within a family into two types, satisfaction with children and satisfaction with conjugal relations, and then to examine whether they have any modulating effect on the depression after retirement. The third is to find out ways of social welfare program that can successfully intervene in solving the depression problems retired people may have. The results of this research are as follows. First, the types of retirement are devided into three groups: voluntary retirement, reluctant retirement and retirement due to age limit. People who choose a voluntary retirement have the lowest level of depression. Second, only the level of satisfaction they get fiom their children has an influence on the level of depression. The results suggest that differentiated ways of intervention are needed according to the types of retirement. Especially, there is a greater need to focus or the reluctantly retired group. In case of reluctant retirement, programs should be provided in order to increase the level of satisfaction they get from the children.
