Introduction: Compared to other types of caregiver, spouse-caregivers tend to be closer to people with Alzheimer’s disease (PwAD) because of their different position in the relationship. We designed this study to compare the differences in caregivers’ quality of life (QoL) and domains of QoL according to the kinship relationship between the members of caregiving dyads. Methods: We assessed QoL of 98 PwAD and their family caregivers (spouse-caregivers, n = 49; adult children, n = 43; and others, n = 6).
