Background: Given the growing number of family members who provide care to adults with a disability or illness, this study examined differences in coping resources and mental health among family caregivers of persons with various health conditions. Methods: Within the context of Ensel and Lin’s stress paradigm, 234 family caregivers participated in an online study by completing validated measures of resourcefulness, spiritual practices, caregiver burden, anxiety, and depression. Caregivers were categorized into nine groups according to their care recipient’s condition. Results: The groups differed significantly on burden and resourcefulness. Greatest burden and lowest resourcefulness were found in caregivers of persons with traumatic brain injury, stroke, and dementia. Caregivers across all groups were found to be at a similarly high risk for anxiety and depression. Conclusions: These results provide insights for tailoring interventions for caregivers, particularly those whose care recipients have traumatic brain injury, stroke, or dementia, who may benefit from resourcefulness training.
