Comparison of Obsessive-Compulsive Disorder and Schizophrenia With Comorbid Obsessive-Compulsive Disorder in Terms of Insight, Metacognitive Beliefs, and Clinical Features.

The aim was to compare insight levels into obsessive-compulsive symptoms (OCS), and metacognitions of patients with obsessive-compulsive disorder (OCD) and with schizophrenia with comorbid OCD (SZ-OCD). Thirty OCD patients and 30 SZ-OCD patients were evaluated; no significant difference was found between the groups in the Brown Assessment of Beliefs Scale (BABS) and the Metacognition Questionnaire-30 (MCQ-30). When all patients were divided into two groups regardless of the presence or absence of schizophrenia as "good insight" and "poor or no insight," the MCQ-30 total score was found to be higher in the "poor or no insight" group and showed a significant but moderate positive correlation with the BABS score. This study supports that the level of insight into OCS in SZ-OCD is not significantly different from patients with OCD. Metacognitions differ not according to the distinction between OCD and SZ-OCD but according to the level of insight in whole OCD sample.
