One goal of the current research was to apply a previously developed method of assessing social support networks (SSNs) to a relatively unstudied population: "frail" elderly Medicaid-eligible home and community-based service (HCBS) recipients, and to evaluate the effect of isolation on SSNs and perceived quality of the network members. This population is of interest because many states are shifting the site of care from long term facilities, such as nursing homes, to the private homes of Medicaid eligible elderly. Forty personal interviews were carried out. Results show that less isolation is associated with larger SSNs (r = -.618), as well as higher perceived quality of relations (r = -.366).
