Abstract

To translate, culturally adapt, and validate a Brazilian Portuguese version of the Yale-Brown Obsessive Compulsive Scale modified for Body Dysmorphic Disorder (BDD-YBOCS). Ninety-three patients of both sexes seeking rhinoplasty were consecutively selected at the Plastic Surgery Outpatient Clinic of the Universidade Federal de São Paulo, Brazil, between May 2012 and March 2013. The BDD-YBOCS was translated into Brazilian Portuguese. Thirty patients participated in the cultural adaptation of the scale. The final version was tested for reliability in 20 patients, and for construct validity in 43 patients (correlation of the BDD-YBOCS with the Body Dysmorphic Disorder Examination [BDDE]). Total Cronbach's alpha was 0.918. The BDD-YBOCS had excellent inter-rater (intra-class correlation coefficient [ICC] = 0.934; p < 0.001) and intra-rater reliability (ICC = 0.999; p < 0.001). Significant differences in BDD-YBOCS scores were found between patients with and without BDD symptoms (p < 0.001), and among patients with different levels of BDD severity (p < 0.001). A strong correlation (r = 0.781; p < 0.001) was observed between the BDDE and the BDD-YBOCS. The area under the receiver operating characteristic curve was 0.851, suggesting a very good accuracy for discriminating between presence and absence of BDD symptoms. The Brazilian Portuguese version of the BDD-YBOCS is a reliable instrument, showing face, content and construct validity.
