Structural and functional features of social networks and demographic variables were explored in a study of 50 clinic-referred and 76 nonclinic black, low-income, single-parent families. Dysfunctional families evidenced asymmetrical reciprocity within network relationships and had more stressful home environments than did nonclinical families. It is suggested that diagnostic evaluation of these families should assess the level of meaningful support provided by the social network.

Stressful life events and the effects of demographic and social network variables were explored in a study of 50 clinic-referred and 76 nonclinic, black, low-income, single-parent families. Dysfunctional families evidenced greater stress and social network characteristics were not significant mediators. The family's internal resources may be the most important buffer against stress.
