N2 - Aims: The aims of this study were to conduct a meta-analysis and meta-regression to estimate the prevalence rates for obsessive compulsive symptoms (OCS) and obsessive compulsive disorder (OCD) in schizophrenia, and to investigate what influences these prevalence rates. Method: Studies were identified via an online OVID database search, including PsychInfo, Embase and Medline until December 2009. Results: Forty-three studies summarizing outcomes for 3978 subjects met inclusion criteria. The mean OCD prevalence is 12.3%, slightly increasing to 13.6% after adjustment in meta-regression. The prevalence rate of OCS, defined as any obsession or compulsion is 30.7% (30.3% adjusted). Higher severity of OCS, DIGS assessment, and Sub-Saharan African origin of study are associated with a lower OCS/OCD prevalence rate, use of DSM-IV edition, Y-BOCS assessment and longer schizophrenia history are associated with a higher prevalence rate. Conclusion: The prevalence of OCS and OCD in schizophrenia is substantial, specifically in more chronic patient populations and is influenced by the method of assessment. © 2013 Elsevier B.V.
