Accessible support programs can improve health outcomes for family caregivers of older relatives with a chronic condition. Over the course of 6 months, 27 experienced family caregivers provided weekly support via the telephone to 66 individuals, either new family caregivers of seniors recently diagnosed with stroke or newly vulnerable family caregivers (i.e., facing increasing demands from the deterioration of their senior relative's condition) of seniors with Alzheimer's disease. Qualitative data documented the perceived impact of the intervention, including increased satisfaction with support, coping skills, caregiving competence and confidence, and decreased caregiver burden and loneliness. Caregivers identified varied support processes that overcame support deficits in their social networks. These processes can facilitate replication in future research and inform practice, programs, and policies.
