Based on a sample of 103 schizophrenics, this paper utilizes path analysis to examine the interrelationships among a number of patient and residence characteristics on different network dimensions. Residents' social competence was consistently found to maintain the strongest association with many of the outside‐facility network dimensions. Despite the mediation of a third of its effect through social competence, decreased periods of hospitalization remained a significant influence in these equations. Residential facilities emphasizing autonomy contributed minimally to some of the external network domains. Conversely, less demanding residential programs and lengthy periods of hospitalization were significantly associated with the within‐facility network dimension. Neither premorbid social adjustment nor length of tenure within a residence had a direct effect on any network dimension in the complete model. Treatment and policy implications are discussed based on the differential determinants of network dimensions found in this study.
