Social support networks of adults with mental retardation who live at home.

The social support networks of 418 adults with mental retardation who live at home were found to be large, durable, active, and diverse in their composition. Family members predominated as members of these support networks. Differences were found in many network characteristics based on the gender and level of mental retardation of the adults. Males and those with the most severe mental retardation were found to be at risk for social isolation. Contrasts with the social support networks of adults in nonfamily settings were discussed.
