Prevalence of Psychotic Disorders in Patients with Obsessive-Compulsive Disorder

Published online by Cambridge University Press:  07 November 2014

Abstract

Introduction: The co-occurrence of obsessive-compulsive disorder (OCD) in patients with schizophrenia and related disorders has been increasingly recognized. However, the rate of psychosis comorbidity in OCD patients has yet to be systematically evaluated.

Methods: The prevalence of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition psychotic disorders was evaluated in 757 subjects consecutively referred to a specialised diagnostic and treatment facility for OCD. Demographic and clinical characteristics were assessed.

Results: Thirteen OCD patients (1.7%) also met the DSM-IV criteria for a psychotic disorder. We found no significant differences in clinical characteristic between OCD patients with and without a psychotic disorder, although patients with OCD and a psychotic disorder more likely used illicit substances and more likely were male.

Conclusion: Relatively few patients referred to a specialized treatment OCD center suffer from a psychotic disorder.
