The Validation and Reliability Study of Turkish Versions of Yale-Brown Obsessive Compulsive Scale Modified for Body Dysmorphic Disorder and Body Image Disturbance Questionnaire
Objective: Body dysmorphic disorder (BDD) is a relatively common disorder and accepted as one of the obsessive-compulsive spectrum disorders group. No tests for BDD have been translated into Turkish yet. This study aimed to perform validity and reliability tests on the Turkish version of the Yale-Brown ObsessiveCompulsive scale Modified for BDD (T-YBOCS-BDD) and the Body Image Disturbance Questionnaire (T-BIDQ). Methods: The patients who were admitted to the clinics of the dentistry faculty with the aesthetic problems were selected as the study group (n=80) and the control group was designed with the patients with non-aesthetic problems (n=81). The tests were administered to the patients within one week with the test and re-test method. Factor analysis was performed, and the statistical significance was accepted as p<0.05 Results: In the evaluation of reliability, Cronbach’s alpha was 0.808 for the T-YBOCS-BDD and it was 0.780 for the T-BIDQ. The factor analysis scores were 0.705 and 0.736, whereas and the valuesof the Bartlett’s test of sphericity were 677,296 (df=66, p<0.001) and 336,069 (df=21, p<0.001), respectively. Total mean scores of T-YBOCS-BDD revealed statistically significant results (p=0.006). Conclusion: The tests resulted in high validity and reliability, therefore the results of this study highly recommended clinicians to perform these tests in the Turkish language-speaking countries.
