Abstract
Olfactory reference syndrome (ORS) is known to have the clinical features of both obsessive-compulsive disorder (OCD) and social anxiety disorder (SAD). However, there has been no clear explanation as to why ORS has the characteristics of two different disorders. In the present study, the comorbidity rates of ORS in patients with SAD (without OCD, n = 83), ORS in patients with OCD (without SAD, n = 42), and patients with SAD and OCD comorbidity (n = 17) were compared. Of all 142 patients studied, 11 were diagnosed with ORS. The comorbidity rate of ORS in comorbid SAD/OCD group was significantly higher than those in both SAD and OCD groups. Logistic regression analysis of 100 cases of SAD and selected 69 cases of generalized SAD showed that the risk of ORS was significantly higher in patients with OCD and bulimia nervosa. Of 59 cases with OCD, the risk of ORS was significantly higher in patients with SAD. The results of the present study suggest that the comorbidity of SAD and OCD most likely explains the development of ORS.
