Clinical characteristics in obsessive-compulsive disorder with schizophrenia

The objective of this study was to compare two groups of patients with obsessive-compulsive disorder (OCD) with and without comorbid schizophrenia in terms of demographic and clinical features. A total of 65 patients diagnosed with OCD were divided into two groups: one comprising 20 patients with schizophrenia and the other comprising 45 patients without schizophrenia. The groups were then compared with respect to demographic variables and scores obtained on various scales. The two groups were similar for the frequency and severity of obsessive-compulsive symptoms. Insight into obsessive-compulsive symptoms was significantly better in the group with schizophrenia. Our findings suggest that the characteristics of obsessive-compulsive symptoms in schizophrenic OCD patients are similar to those in nonschizophrenic OCD patients. (C) 2003 Elsevier Inc.
