Validation of the portuguese version of the Questionnaire on Eating and Weight Patterns: revised (QEWP-R) for the screening of binge eating disorder

Abstract

(QEWP-R) for the screening of binge eating disorder Validação da versão em português do Questionário sobre Padrões de Alimentação e Peso -Revisado (QEWP-R) para o rastreamento do transtorno da compulsão alimentar periódica A b s t r a c t Objective: The present paper describes the validation of the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R) designed for the diagnosis of binge eating disorder (BED) and sub-clinical binge eating. Methods: 89 overweight women seeking treatment for binge eating and/or obesity were assessed with the Portuguese version of the Questionnaire of Eating and Weight Patterns and were, subsequently, interviewed with the eating disorders module of the Structured Clinical Interview for DSM-IV (SCID-I/P The QEWP-R includes questions on overeating and loss of control, distress related to eating behavior, importance of weight and shape and compensatory weight control behaviors. It provides decision rules for the differential diagnosis between BED and purging or non-purging bulimia nervosa based on YES-or-NO answers to questions assessing the presence or absence of binge eating and compensatory methods for weight control.13 Following DSM-IV criteria, BED is considered positive when the subject endorses binge eating occurring at least twice a week associated with significant distress, without inappropriate compensatory methods for weight control. The instrument also assesses age, gender, ethnic background, education, height, weight and dieting behavior.The QEWP-R was translated into Portuguese by eating disorders experts 13 and pilot-tested on eating disorders patients of the Eating Disorders Program of UNIFESP. The Portuguese version was then back-translated into English and submitted to one of the authors of the original questionnaire (S.Z.Y.), whose suggestions were included in the final version of the translation.In this study, subjects were classified as having BED when meeting full criteria as proposed in the Appendix B of the DSM-IV.

The Eating Disorder Inventory in the screening for DSM-5 binge eating disorder

“…Several alternative instruments have been developed to screen for BED, and many of them have reasonable screening properties (Borges et al, 2005;Celio et al, 2004;Grupski et al, 2013;Striegel-Moore et al, 2010;Vander Wal et al, 2011). However, we believe that the EDI has some important advantages.…”

“…The Binge Eating Scale (BES) had a sensitivity and specificity of 94% and 76% in bariatric surgery candidates (Grupski et al, 2013) and 85% and 20%, respectively, in subjects with binge eating Eating Behaviors 22 (2016) [145][146][147][148] (Celio, Wilfley, Crow, Mitchell, & Walsh, 2004). The Questionnaire for Eating and Weight Patterns-Revised (QEWP-R) had a sensitivity and specificity of 74% and 35% in subjects with binge eating (Celio et al, 2004), and 55% and 80%, respectively, in women seeking treatment for obesity and/or binge eating (Borges, Morgan, Claudino, & da Silveira, 2005). We identified only one study where screening was performed in a community sample: the Patient Health Questionnaire eating disorder module (PHQ-ED) yielded a sensitivity of 100% and a specificity of 92% against diagnosis obtained by the Eating Disorder Examination in a community sample of young adult males and females (StriegelMoore et al, 2010).…”

Compulsão alimentar e bulimia nervosa em praticantes de exercício físico

“…O QEWP-R mostrou ser útil na detecção de prováveis casos de compulsão alimentar e está indicado para o rastreamento do TCAP na população geral e para distinguir BN purgativa e BN não purgativa 1,17,18 . Ressalta-se que este é um instrumento de triagem e definição de quadro de comportamento alimentar, e que os participantes do estudo não foram submetidos à entrevista para diagnóstico clínico.…”

“…DISCUSSÃO O baixo índice de prevalência de transtorno da compulsão alimentar periódica em praticantes de exercício físico encontrado neste estudo (0,97%), apesar de mostrar-se divergente dos resultados encontrados na literatura nacional 4,5 , está em consonância com pesquisas epidemiológicas internacionais, as quais sugerem uma prevalência em torno de 0,7% a 3% em população geral 18 . Outros autores observaram prevalências distintas, que variavam conforme as características da amostra, como o tamanho, a idade investigada e os grupos aos quais os indivíduos estudados pertenciam, tornando limitada a comparação com esta pesquisa 20 .…”

The Prevalence of Childhood Trauma and Parental Caretaking Quality among Gastric Surgery Candidates

“…The QEWP-R is a 27-item, self-report measure that explores weight and dieting history, binge-eating behavior, and purging behavior. Previous studies indicate that the QEWP-R identifies individuals with clinically meaningful BED (Elder et al, 2006) and is a useful screening measure for the disorder (Borges, Morgan, Claudino, & da Silveira, 2005;Celio, Wilfley, Crow, Mitchell, & Walsh, 2004). In this study, we excerpted from the QEWP-R five key items relating to the diagnosis of BED and included a list of exclusionary purging behaviors.…”
