The purpose of this study are to examine the influential variables between general character, family system, coping strategies, social support and stress of main caregivers for disordered elderly family. This study was conducted by interviewing of 177 family-members care to giving disordered elderly families in Taegu and Kyeongbuk province. The data were analyzed with the SPSS statistical package using frequency and percentage, multiple regression and path analysis. The results of this study were as follow : The variables influencing stress related to the disordered elderly family are the degree of disorder (${eta}=.348^{***}$), caring-time-per day (${eta}=.303^{***}$), employment status of main caregivers (${eta}=.223^{***}$), social support (${eta}=.241^{**}$), relational coping strategies (${eta}=.199^{**}$), problem-avoidance coping strategies (${eta}=.327^{***}$). Thus, in disordered elderly families, a high-stress situation arises with a highly-educated caregiver when problem-avoidence coping strategies or relational coping strategies are used or when daily caring time is great. A low-stress situation results when the caregiver is employed and the social support level is high.
