This study aims to determine the prevalence of obsessive compulsive disorder (OCD) among schizophrenic patients and the association of this condition with clinical and selected neurocognitive factors. This is a cross sectional study on one hundred schizophrenic patients who attended psychiatric clinic in National University Hospital and Kuala Lumpur Hospital over a four-months period. All patients diagnosed as schizophrenia according to DSM 1V were assessed using Mini International Neuropsychiatric Interview (MINI) Version 5 for the presence of Obsessive Compulsive Disorder, Brief Psychiatric rating Scale (BPRS) for severity of psychosis and Yale Brown Obsessive Compulsive Scale (YBOCS) for severity of obsessive compulsive (OC) symptoms. Socio-demographic data were obtained by direct interview. The neurocognitive assessment were done using Mini Mental State Examination , Rey Auditory Verbal Learning Test (RAVLT) and Digit Span. Fifteen percent of schizophrenic patients (15%) in this sample were found to have a diagnosis of Obsessive compulsive Disorder (OCD). The OCD and non-OCD schizophrenic patients did not differ significantly in term of age ,gender, race and family history of mental illness. However they differ significantly on employment, type of treatment medication and the presence or severity of current psychosis. Schizophrenic patients with OCD also showed no significant different in selected neurocognitive functions.
