Unique contribution of family functioning in caregivers of patients with mild to moderate dementia

The relationship between family functioning and dementia caregiving is complex. The present study examined the interrelationships between family functioning, caregiver burden, and patient characteristics. Participants were 72 live-in, family caregivers of patients with mild (n = 47) or moderate dementia (n = 25). Caregivers completed measures of burden, family functioning, depression, and anxiety. Ratings of patients' memory/behavior problems and patients' activities of daily living were also collected. Results indicated that higher levels of caregiver burden were significantly associated with increased caregiver depression and anxiety, greater frequency of memory and behavior problems in the dementia patient, worse activities of daily living, and poorer family functioning. Even after controlling for caregiver depression, caregiver anxiety, and frequency of memory/behavior problems in dementia patients, poorer family functioning continued to be associated with higher levels of caregiver burden. Caregivers with high levels of burden reported greater family dysfunction in communication and roles, regardless of their relationship to the patient (i.e., spouse or child). These findings suggest that including a family systems component in caregiver interventions may be beneficial in reducing burden in these very distressed individuals.
