Effects of nursing care on time use behaviour: a comparative analysis in Japan.

This study attempts to clarify differences in Japanese time use behaviour for people with/without responsibility for nursing care of family members by comparing the behaviour of three population groups: in-home caregivers, out-of-home caregivers and non-caregivers. The analysis is also conducted with respect to the behaviour on weekdays and weekends. After examining the differences of time use behaviour based on simple statistical tests, we develop a multilevel multiple discrete-continuous extreme value model, which simultaneously represents activity participation and time allocation. In the model, observed variations, unobserved inter-individual variations and unobserved spatial variations are distinguished. Using large-scale national time use data collected in Japan, the analysis confirms various differences of time use behaviour across the three groups, especially between in-home caregivers and non-caregivers.
