Objectives: This study examined the dyadic effects of self-rated health on the life satisfaction of family caregivers. The effects of the use of long-term care services were also explored to investigate whether support through care services is associated with the life satisfaction of family caregivers. Methods: The data were drawn from the sixth wave (2016) of the Korean Longitudinal Study of Aging. Caregivers who used long-term care services for older family members, and spouses of the caregivers, were identified.
