ABSTRACT
The Questionnaire on Eating and Weight Patterns-5 is a self-report instrument developed for the screening of Binge Eating Disorder (BED) and Bulimia Nervosa (BN) according to DSM-5. The present study aimed to examine the concurrent validity of the Brazilian version of QEWP-5 to assess BED and BN in the general population. The Brazilian version of QEWP-5 was administered to 2297 subjects, aged from 18 to 60 years. All screen-positive and a subset of screen-negative participants were also interviewed by telephone using the eating disorders (ED) module of Structured Clinical Interview for DSM-IV - Patients Version (SCID-I-P) for the assessment of BED, BN, and their subthreshold forms. For the assessment of BED, the sensitivity of QEWP-5 was 0.41 and its specificity was 0.90. The positive and negative predictive values were 0.48 and 0.87, respectively. Regarding the assessment of BN, QEWP-5 showed a sensitivity of 0.56, a specificity of 0.90, a positive predictive value of 0.35, and a negative predictive value of 0.95. For the global screening of ED (BED, BN, and subthreshold forms), QEWP-5 showed a sensitivity of 0.71, a specificity of 0.83, a positive predictive value of 0.64 and a negative predictive value of 0.87. QEWP-5 can be a useful instrument for the initial screening of diagnostic threshold ED psychopathology in general population samples. However, it has less utility in identifying cases of BED and BN independently.
