Abstract
BackgroundThe BDDQ-AS (Body Dysmorphic Disorder Questionnaire—Aesthetic Surgery) is a simple and reliable patient-reported outcome measure. It can be used as a screening tool for body dysmorphic disorder (BDD) in patients undergoing aesthetic rhinoplasty. The aim of this study was to translate and culturally adapt the Mandarin version of the BDDQ-AS (M-BDDQ-AS) and evaluate its selected psychometric validation in patients after rhinoplasty.MethodAccording to international guidelines, the BDDQ-AS questionnaire was translated from English to Mandarin. Twenty Mandarin-speaking rhinoplasty patients were interviewed in order to evaluate the understandability and acceptability of the translation and produce a final version. It was then administered to 137 patients with a mean age of 38.75 ± 6.24 years. Psychometric validation were evaluated using reliability (internal consistency, test–retest reliability) and item-reponse theory (IRT) test.ResultHigh internal consistency of 0.823 was found using Cronbach’s α coefficient. Reliability of the M-BDDQ-AS resulted in Intraclass Correlation Coefficient (ICC) = 0.863. Besides, based on IRT analysis, the discrimination abilities of all the items were good (over 2.0), and their difficulty estimates were reasonable.ConclusionThe M-BDDQ-AS is a reliable and valid self-reported questionnaire that can be used in rhinoplasty patients. The very good psychometric validation of the M-BDDQ-AS indicates that it can be used in clinical practice and scientific research.Graphical

Summary
Body dysmororphic disorder (BDD) is a chronic psychiatric illness that is difficult to diagnose, causes significant anxiety, and is difficult to cure. The individual feels compelled to examine, improve, or conceal the perceived deficiency on a regular basis [3] To improve their perceived blemish and alleviate these symptoms, people with BDD often seek cosmetic surgery. Patients with BDD who undergo aesthetic treatment often take up the surgeon’s time with frequent phone calls and requests for additional consultations and procedures. These patients tend to file malpractice suits and may even become physically violent toward their surgeons [8–11].
