Abstract: Objective To evaluate the reliability and validity of body dysmorphic disorder questionnaire (BDDQ) Chinese version. Methods A total of 222 participants from a plastic surgery department were enrolled in the study by systematic sampling. They were measured with BDDQ Chinese version and interviewed with Structured Clinical Interview for DSM-]V-TR-Patients( SCID/P) to evaluate the validity. Fifty participants were assessed again after two weeks to evaluate the test-retest reliability. Results The sensitivity of BDDQ Chinese version was 100% and the specificity was 93%. The correlation coefficient of each item was between 0. 808 and 1.000(P＜ 0.001). Conclusion BDDQ Chinese version has fairly high reliability and validity. Thus, it can be used as a screening diagnosis tool for BDD.
