Social networks and the support that network members provide are important resources for family caregivers in sustaining their caregiving role. Caregivers' perceptions of support from family and friends have been linked to their health status (R. Kahn & T. Antonucci, 1980; I. Sandler & M. Barrera, 1984). The purpose of this study was to explore the social networks and types of perceived support described by women who are caregivers of cognitively impaired older adults. Content analysis was used to examine interview data from a longitudinal qualitative study of 20 women caregivers of cognitively impaired older persons. An important finding of this study was the identification of a typology of social networks of the women caregivers. The caregivers' perceptions of satisfaction with support received and experience of conflict with network members varied according to the characteristics of their social network. Those caregivers who belonged to diverse social networks reported high satisfaction with the support that they received and little or no conflict. Those caregivers with kin-dominated social networks reported little satisfaction with support received and a high degree of conflict.
