ABSTRACT
Objective: To translate, culturally adapt, and validate a Brazilian Portuguese version of the Yale-Brown Obsessive Compulsive Scale modified for Body Dysmorphic Disorder (BDD-YBOCS). Methods: 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]). Results: 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. Conclusion: The Brazilian Portuguese version of the BDD-YBOCS is a reliable instrument, showing face, content and construct validity.

El estudio de los mayores de 15 años en una muestra probabilística de conglomerados familiares en un área de salur evidenció una mayor proporción de consumo de tabaco, café y alcohol en el sexo masculino; proporciones importantes de consumidores de tabaco y café en que se reportaron síntomas de abstinencia ante la supresión brusca del tóxico; y cifras de 2,4% y 1,7% de sujetos reportados como bebedores abusivos entre el subtotal de consumidores y el total de integrantes de la muestra respectivamente, cifras muy inferiores a las reportadas en otras latitudes. Los autores recomiendan realizar estudios de mayor casuística o incrementar la divulgación de los riesgos del consumo de café y alcohol, de forma excesiva
