Abstract: Objective

·To test the effects of obsessive beliefs and impulsivity traits on different subtypes of obsessive-compulsive (OCD).

Methods

·A total of 139 non-medicated OCD patients and 110 matched healthy controls (HCs) were enrolled. The clinical symptoms were evaluated separately using Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Obsessive Beliefs Questionnaire-44 (OBQ-44), Barratt Impulsiveness Scale (BIS-11), and Obsessive Compulsive Inventory-Revised (OCI-R). Multiple linear regression analysis was used to evaluate the influence of obsessive beliefs and impulsive traits on symptom dimensions of obsessive-compulsive disorder.

Results

·The scores of all clinical scales of OCD patients were significantly higher than those of HCs (P<0.05). Obtained by multiple regression, the checking score was affected by responsibility/threat estimate (RT) and motor impulsiveness (MI) (B=0.053, P=0.00; B=-2.000, P=0.011); the ordering score was significantly affected by the perfectionism/certainty (PC) belief (B=0.049, P=0.001); the score of obsessing was affected by the belief in RT (B=0.082, P=0.000); the neutralizing score was affected by both RT belief and cognitive impulsiveness (CI) (B=0.038, P=0.006; B=0.248, P=0.044).

Conclusion

·OCD patients with different obsessive-compulsive beliefs and impulsivity traits will conduct different symptoms.

Key words: obsessive-compulsive symptoms, obsessive beliefs, impulsivity traits
