The purpose of this study was to investigate various factors related to life satisfaction in home-1iving elderly. Structured interviews using questionnaire and measurement of the comprehensive life satisfaction level using visual analogue scale were performed. The subjects were 76 home-living elderly joining day-service program once a week. They were all female and their ages were from 65 to 91 years old. The results were as follows: 1) The comprehensive life satisfaction level showed a bimodal distribution with peaks at 90-100 and 50-59, out of a possible 100 points. 2) Univariate analysis indicated that the comprehensive life satisfaction level was significantly higher in the elderly who had better economic status. The elderly who had hobby in her life tended to have higher level of comprehensive life satisfaction, whereas the elderly who had been supported by the welfare service system for elderly people except for day-service tended to have lower level of satisfaction. 3) Path analysis indicated that better economic status increased the comprehensive life satisfaction level, whereas experience of support from the welfare service system decreased it with statistical significance. Participation in social activities and higher health status evaluated by themselves tended to increase the level of comprehensive life satisfaction, and supporting care by family member tended to decrease it.
