The growing population of seniors with disabilities experiences unmet support needs and loneliness. Although support deficiencies can be overcome by peers in support groups, most support groups are inaccessible to older adults with limited physical functioning. Accordingly, this project aimed to develop and test the impact of an accessible telephone support group intervention for seniors with disabilities. Six research questions guided the study. Four telephone support groups with five to six participants (n = 23) were created, each with a professional and a peer (senior) leader. The groups met once a week for 12 weeks. Qualitative analyses of the telephone transcripts and post-intervention interviews of participants and leaders revealed decreased support needs, diminished loneliness, and enhanced coping. Selection, training, and support of peer and professional leaders and member control of discussions were important ingredients of successful support groups.
