    Abstract:
    OBJECTIVE: The present study aimed to determine if schizophrenic patients with OC-symptoms represent a subtype of schizophrenia and to evaluate the differences between schizophrenic patients with OC symptoms and OCD patients. METHODS: The study included 20 patients diagnosed with OCD, 40 schizophrenic patients, and 20 schizophrenic patients with OC symptoms. While the distribution and the severity of psychotic symptoms in the OC-schizophrenia group were compared to those of the schizophrenic patients, and while the distribution and severity of obsessive-compulsive symptoms of the OC-schizophrenia group were compared to OCD patients, all 3 groups were compared to each other in terms of demographic data and other clinical characteristics. RESULTS: There were no differences in the distribution and severity of psychotic symptoms between the OC-schizophrenia group and the schizophrenia group. Moreover, the distribution and severity of OC symptoms in the OC-schizophrenia group were no different than those in the OCD group. Brief Disability Questionnaire scores were significantly higher in the OC-schizophrenia group than in the other 2 groups. Hamilton Depression Scale and Hamilton Anxiety Scale mean scores were significantly higher in the OCD and OC-schizophrenia groups than in the schizophrenia group. Moreover, Yale-Brown Obsessive-Compulsive Scale total scores were not correlated to the Scale for the Assessment of Negative Symptoms or the Scale for the Assessment of Positive Symptoms scores in the OC-schizophrenia group. CONCLUSION: According to our results OC-schizophrenia might be a sub-type of schizophrenia, which doesn't have more severe psychotic symptoms, but more severe depression and anxiety, which are related to greater disability.
