Social support and strain of family caregivers of older adults.

To assess the direct effects and interactive models of social support, caregivers to functionally impaired older adults were identified by hospital personnel. Within a week of referral, family caregivers were interviewed in the home about strain, depressive symptomatology, caregiving appraisal, informal social support, and coping. Caregiving appraisal significantly explained strain and depressive symptomatology. The interaction of social support with strain did not moderate or lessen depressive symptomatology. These findings suggest that nursing continue to examine the effect of home health care on strain and depressive symptomatology of caregivers of older adults.
