This study used data from the long-term experimental evaluation of the Program of Assertive Community Treatment (PACT) to examine the clinical and situational contributors to social functioning in people with schizophrenia. Subjects were 87 young adults with schizophrenia spectrum disorders. Data from two time points, 6 months apart, were used to test models predicting five social outcomes (network size, network reciprocity, sociosexual contact, satisfaction with social relationships, and loneliness) from positive symptoms, work involvement, living situation, and residential mobility. Results indicated that (1) work involvement was associated with larger network sizes over a 6-month period; (2) experiencing an increase in positive symptoms over a 6-month period was associated with the loss of reciprocal network ties, a lessening of satisfaction with social relationships, and an increase in loneliness; and (3) neither living situation nor moving frequently was associated with later social outcomes. These findings suggest strong support for the role of short-term changes in positive symptoms and modest support for the role of work involvement in social outcome.
