Objective: A paucity of research exists on burden of care (BoC) and factors associated with it among minority groups, such as Ultra-Orthodox Jews. The aims of this study were (1) to portray the profile of Ultra-Orthodox Jewish (UOJ) caregivers and their BoC;(2) to explore relations between care recipients' characteristics, care situations, characteristics of caregivers, and BoC. Methods: A total of 107 UOJ (66 women, 41 men) family caregivers were interviewed face to face in their homes, using valid and reliable measures. Results: Participants reported moderate BoC and high level of social support. Caregiver's self-rated health, caregiver's anxiety, and social support emerged as significant predictors of caregiver burden. Conclusions: Our findings might help social workers and other health professionals to better understand the unique characteristics of the UOJ community and to target caregivers with higher anxiety, lesser social support, and poorer self-rated health in order to reduce their caregiving burden.
