The current study focuses on studying the co morbidity of OCD among the patients of Anxiety and depression. A total of 70 patients of (35 with anxiety disorder and 35 depressive disorders) were included in this study. HARS, HDRS and YBOCS were applied in all the patients who fulfilled the selection criteria.

Furthermore, around 17.1% patients of depressive disorder were found to have severe OCD symptoms whereas 8.5% were found to have extreme co morbidity of OCD.
