Objectives: To examine the associations and the mechanisms between caregiver burden and compassion fatigue among family caregivers. Method: A cross-sectional study comprising 300 family caregivers of older relatives in Arab communities in Israel was conducted. Data were collected via face-to-face interviews in Arabic using structured questionnaires to identify factors associated with compassion fatigue (using a secondary traumatization stress scale). Bootstrapping with resampling strategies tested the multiple mediator model.
