Purpose : The purpose of this study was to examine the study of health seminar for preventive health care and self-help in ADL of "care house" residents. Subjects and Methods : Subjects consisted of 17 residents at a care house. Based on a survey of physical, psychological, and social functions, a seminar program was established, and 2-hour sessions were conducted every two weeks, continuously for 4 months. Results : Regarding changes in ADL scales, significant improvement were observed in the total ADL-20 and in the IADL subscale for females. Comparisons of score differences before and after the program revealed significant positive correlation between age and the BADL subscale. Individuals who weren't using Long-team Care Insurance (LTCI) showed significantly higher values for the total ADL-20 and the BADL subscale than those who were using LTCI. Regarding social support scales, a significant increase in the subscale of passive-instrumental support was observed among females. In terms of subjective happiness based on the PGC morale scale, significant increases were observed in the subscales of attitudes towards aging, loneliness, and dissatisfaction among all subjects. Conclusion : Effects of this seminar program on "care house" residents were observed. It was suggested that the program increased the communication among residents, and triggered enhanced motivation, and individual interaction. The results indicated the importance of nursing interventions for preventive health care with "care house" residents, as well as frail elderly residents of the community.
