ABSTRACT Background While rapid population ageing is occurring worldwide, its speed is especially prominent in Asian countries. In Asia, cultural diversity might significantly affect care burden; however, few studies have investigated the differences in care burden, and mental, physical and social conditions among Asian countries. This study aimed to clarify the situations of and differences in family caregivers (FCs) of older persons in Japan and Thailand, and evaluate the factors associated with care burden in both countries. Methods A cross‐national survey of 217 in‐home FCs was conducted in Japan and Thailand and mainly included items regarding care burden and psychosocial conditions. Differences between the two countries were obtained, and the factors associated with care burden were analysed by multiple regression analyses. Results The FCs' and care receivers’ mean ages (64.8 ± 11.1 and 84.8 ± 8.6 years, respectively) in Japan were significantly higher than the mean ages (49.1 ± 13.3 and 77.1 ± 9.5 years) in Thailand. In Japan, FCs had more severe care burden, loneliness, and stress compared to those in Thailand. In Thailand, FCs had more social connections and informal support than those in Japan. The factors associated with care burden were different in each country; thus, severe stress, low emotional care preparation, and low willingness to continue care at home were significantly associated with severe care burden in Japan, whereas poor relationships with care receivers, few social connections, low confidence in providing care, low emotional care preparation, and lack of informal support were significantly associated with severe care burden in Thailand. Conclusions Despite there being a long‐term care insurance system in Japan, which is absent in Thailand, care burden and psychosocial conditions of FCs might be worse in Japan. There was a clear difference in the factors associated with care burden between Japan and Thailand.
