Abstract
OBJECTIVE: Frequency data on mental disorders is a crucial requirement for primary, secondary and tertiary prevention. However, such local data is sparse. The study aimed to estimate frequency and gender differences of Obsessive Compulsive Disorder (OCD) in clinical population. METHOD: Retrospective data of adult patients (18 years and above) reported in Out Patient Departments (OPD) of four teaching hospitals and a private clinic was collected. Successive three years record was consulted using OPD registers. Gender difference in frequency of OCD was estimated. RESULTS: Altogether 90119 patients were registered in five psychiatric settings in major cities of Punjab during three year period. As information was missing for over one third of the registered patients, hence analysis was carried out on valid cases only i.e. 59220 (65.8% of the total number of patients registered). It was revealed that the estimated frequency of OCD is 4.1%. There was no significant gender difference revealed in frequency of OCD (P>.05). CONCLUSION: Frequency of OCD implicate the need for early detection and intervention of the disorder. Further, it elucidates the importance of community based research on other mental disorders. The need for accurate record keeping which is a core element for any research related with medical or psychological issue is also highlighted.
