This article presents analyses of de-identified archival data on the incidence of noncompliance with antipsychotic medication in a sample of 104 patients with schizophrenia (average age 38.2 years, SD=9.9; 41 men, 63 women). Statistical calculations were performed to determine the correlates of episodes of noncompliance leading to a relapse and re-hospitalization within one year of treatment. The data set included 87 symptoms relevant for studies of schizophrenia as well as numerous socio-demographic variables and data on the patient’s history of illness. Noncompliance was associated with symptoms of autism (r=.32, p=.001), widespread delusions (r=.25, p=.01), persistent persecutory delusions (r=.28, p=.004), and a relatively poor premorbid adjustment (r=.33, p=.001). The adjusted R2 from a multiple regression suggested that the four variables accounted for 18% of variance in our noncompliance data.
