The purpose of this study was to evaluate the utility of a self-report measure of social functioning as an outcome measure for older schizophrenia patients. Sixty-five schizophrenia patients and 39 healthy controls, ranging in age from 45 to 81 years, were evaluated using a modified Social Adjustment Scale (SAS-M), Scales for Assessment of Positive and Negative Symptoms, Depression Subscale of the Brief Symptom Inventory, Mini-Mental State Examination, Dementia Rating Scale, measures of social support, and measures of background variables. Compared with controls, fewer patients with schizophrenia engaged in social roles, were married, were parents, or held jobs. Moreover, patients were more impaired in overall functioning, specifically in the domains of social/leisure, extended family, and marital roles than controls. Impairments in most roles were correlated with greater severity of symptoms, but not with degree of cognitive impairment, social environment, or background characteristics. The SAS-M is a useful addition to psychosocial batteries; however, the self-report format may not reflect others' perception of functioning.
