[Burden on family caregivers of frail elderly persons one year after the introduction of public long-term care insurance service in the Onga District, Fukuoka Prefecture: evaluation with a Japanese version of the Zarit caregiver burden interview].

The present study was conducted to investigate the factors related to the feeling of psychological stress, called heavy burden, in caregivers who took care of frail elderly persons 1 year after the introduction of the public long-term care insurance system (i.e., kaigo hoken) in the northern part of Fukuoka Prefecture, Kyushu, Japan. Forty-seven caregivers answered a self-administered questionnaire involving the Japanese version of the Zarit Caregiver Burden Interview (ZBI) and thus described their own caregiving situation. Compared to caregivers with a light burden, heavily burdened caregivers were less likely to have time to go out without their frail elderly, but tended to spend a longer time with them in providing for their physical care. Compared with less burdened caregivers, heavily burdened caregivers tended to be concerned with what others thought or said and more likely to use a short-stay service (i.e., temporary nursing home assistance). More social services should be provided to let caregivers have their own time without caring for their patients. In addition, local governments and caremanagers should help caregivers to understand the benefits of services available for the elderly and their caregivers.
