Stress, social support, and psychological distress of family caregivers of the elderly.

The effects of stress and social support and their interaction with the psychological well-being of 87 family caregivers of impaired elderly were examined. Perceived stress and satisfaction with support accounted for 32% to 36% of the variance in psychological distress or depression, p less than .001; however, when characteristics of the caregiver situation were included in the models, the effects of perceived stress were found to be spurious. The revised models accounted for 44% to 48% of the variance in psychological distress or depression, p less than .000, and included years of caregiving and mental impairment of the elder instead of perceived stress. Although there were no buffering effects for social support, main effects accounted for 19% to 22% of the variance in psychological distress or depression. The findings indicate that caregivers who are caring for a mentally impaired elder, who have been providing care for an extended time, and who have low social support are at high risk for psychological distress or depression.
