The purpose of this research was to explore the home care process for the elderly by families using the Grounded Theory Approach. Twelve families in process of caring for or waiting for caring were picked up for this research by this approach at the two general hospitals in Tokyo. Data were collected through interviews and observations on a continuous basis, being analyzed by the comparative analysis method.In this research, the home care process for the elderly by family was clarified by focusing on the competing needs between or among the family members arose from the “Shiwayose”(the burden shifting) of caregiving at home. The process had 3 properties of 1) distress caused by the shared burden, 2) conflict between or among family members, and 3) mobility of work sharing by family members; and included 3 stages, that is,“The stage of harmony”,“The stage of provisional harmony”, and “The disharmony”. Also it was made clear that the family members used some strategies at the stages of provisional harmony and disharmony to avoid or reduce the needs' competition and continue the home care.The findings suggest that the needs' competition among the family members caused by the Shiwayose of the home care was the critical issue in question. Even if the family members were placed in the worst situation of confusion caused by the needs' competition, they would still have potential power to live together in harmony while continuing the home care. The health provider needs to promote such potential power, supporting the strategies that family use.
