BACKGROUND: The emotion of disgust has been linked with the underlying nature of the contamination subtype of obsessive-compulsive disorder (C-OCD). Prior studies show that disgust contributes to the development of C-OCD by reinforcing avoidance strategies. Therefore, experiential avoidance (EA) may influence the effect between disgust sensitivity (DS) and C-OCD symptom severity. This study aimed to investigate the mediational role of EA between DS and C-OCD severity.
METHODS: A cross-sectional design was adopted with 45 patients of OCD and 45 healthy controls. Both the groups were assessed on the Obsessive-Compulsive Inventory, the Disgust Scale (Revised), and Acceptance and Action Questionnaire-II. Yale-Brown Obsessive Compulsive Scale (Y-BOCS) checklist and symptom severity scale were additionally administered to the patients with OCD. Independent t-tests, Pearson's product-moment correlation, regression analysis, and mediation analysis were used.
RESULTS: DS and EA were positively associated with contamination-washing symptoms and symptom severity. Regression analysis indicated that DS and EA were highly associated with contamination/washing severity scores among both the patients with C-OCD and the healthy controls.
CONCLUSION: The study implicates that disgust is a central emotion underlying the presentation of obsessions and compulsions, which are of contamination concerns. Further, EA has a role in the maintenance of OCD through avoidance learning; however, it may not be interacting with DS to cause OCD.
