Abstract

Patients with an ICD-9 diagnosis of psychotic disorder were assessed for DSM-III-R schizophrenia. Rates of schizophrenia were found to be higher in males (39.8 per 100,000) than females (22.4 per 100,000). The DSM-III-R incidence supports recent studies which suggest a decrease in rates of schizophrenia across time, and also suggests that men suffer from both more schizophrenia and a more severe form of the disease.
