AimTo develop a Japanese version of the short-form FAMCARE Scale (Ornstein, 2015) for family caregivers of terminal cancer patients at home.MethodsThe survey was conducted with 316 family caregivers of terminal cancer patients at home selected as eligible participants in 11 major regions in Japan (the Tokyo metropolitan area, and the prefectures of Tochigi, Ibaraki, Saitama, Chiba, Kanagawa, Nara, Hyogo, Kagawa, Ehime, and Saga). Construct validity was confirmed using a confirmatory factor analysis, and the Caregiver Quality of Life Index-Cancer (CQOLC) scale was administered to assess criterion-related validity.ResultsA total of 120 family caregivers provided valid responses. The mean±standard deviation of the age of the family caregivers was 64.6±12.0 years, and 91 (75.8%) were female. A factor analysis of the results showed that the Japanese version of the 10-item and 5-item short-form FAMCARE Scale was a unidimensional construct, and a confirmatory factor analysis demonstrated a goodness of fit index of 0.910 and 0.972, an adjusted goodness of fit index of 0.835 and 0.916, a comparative fit index of 0.968 and 0.992, and a root mean square error of approximation of 0.095 and 0.081, respectively. The Cronbach's α coefficients of the 10- and 5-item scales were 0.95 and 0.93, respectively. The scale scores were significantly correlated with the family caregiver's quality of life (CQOLC) (10-item r=0.304, P<0.01; 5-item r=0.311, P<0.01).ConclusionThe Japanese version of the 10-item and 5-item short-form FAMCARE Scale was found to have sufficient reliability and validity for assessing family satisfaction with terminal cancer patient at home in Japan.
