Background: Caring for persons with dementia (PWD) can create “caregiver burden,” which is associated with negative outcomes for caregivers and PWD. The ZBI (Zarit Burden Interview) is a widely used unitary measure of caregiver burden. However, recent research has found caregiver burden to be multi-dimensional. The purpose of this study was to explore the factor structure of the ZBI within a sample of UK caregivers. A secondary aim was to identify variables that predicted burden dimensions found.
