Introduction The Questionnaire on Eating and Weight Patterns-5 (QEWP-5) is a self-report instrument developed to screen individuals for binge eating disorder (BED), as defined by the DSM-5. However, this version of the instrument had not been adapted for the Brazilian population. Objective To describe translation and cross-cultural adaptation of the QEWP-5 into Brazilian Portuguese. Methods Translation and cross-cultural adaptation of the QEWP-5 included the following steps: forward translation, comparison of translations and a synthesis version, blind back-translations, comparison of the back translations with the original version, and a comprehensibility test. The comprehensibility test was conducted with a sample of 10 participants with BED or bulimia nervosa and 10 eating disorders experts. Additionally, a Content Validity Index (CVI-I) was calculated for each item and then averaged to produce an index for the entire scale (CVI-Ave), to assess content equivalence. Results Some inconsistencies emerged during the process of translation and adaptation. However, the expert committee solved them by consensus. The participants of the comprehensibility test understood the Brazilian version of QEWP-5 well. Only 2 patients (20%) had doubts about items related to subjective binge eating episodes. Content equivalence analysis rated all items relevant, with CVI-I ranging from 0.8 to 1.0 and an overall CVI-Ave of 0.94. In view of the good overall assessment of the pre-final version of the instrument, additional changes were not made to the final version. Conclusion The Brazilian version of the QEWP-5 was cross-culturally adapted and was well understood by the target population. Further studies are required to assess its psychometric properties.
Os transtornos alimentares (TA) são síndromes psiquiátricas caracterizadas por alterações no comportamento alimentar, preocupação excessiva com o peso e insatisfação com a imagem corporal, impactando a saúde e a qualidade de vida dos indivíduos. Os TA mais estudados são a anorexia nervosa, a bulimia nervosa e o transtorno da compulsão alimentar. Embora apresentem algumas características em comum, a psicopatologia alimentar pode variar de acordo com cada TA. Portanto, os comportamentos alimentares alterados devem ser corretamente identificados para que o tratamento seja realizado adequadamente. Os manuais para manejo dos TA recomendam que o tratamento seja realizado por profissionais especializados, de diferentes áreas, incluindo a nutrição. O presente artigo aborda o papel do nutricionista na avaliação e tratamento dos TA. A avaliação nutricional visa à identificação de sintomas e comportamentos alimentares relacionados a essas condições clínicas. Ademais, o nutricionista deve estabelecer metas de tratamento específicas e individualizadas, objetivando mudanças graduais e sustentáveis. Por fim, destaca-se a importância da atuação de profissionais especializados para a correta identificação de atitudes alimentares disfuncionais e, posteriormente, para a realização do aconselhamento nutricional específico para cada TA.
Background: Grazing is a disturbed eating pattern that has been associated with eating disorders and obesity. One of the new measures to investigate this eating behavior is the Short Inventory of Grazing (SIG), a two-item questionnaire that assesses grazing in general and grazing associated with the feeling of loss of control over eating (LOC grazing). However, the psychometric properties of SIG have not been assessed in the Brazilian population.Objective: The present study aimed to cross-culturally adapt and validate the Brazilia n version of SIG.Methods: SIG was adapted to the Brazilian context following international guidelines.Then, 90 undergraduate students completed an online survey including questions from the SIG, the Binge Eating Scale (BES), the Patient Health Questionnaire-9 (PHQ9), the Generalized Anxiety Disorder-7 (GAD7), and questions related to self-reported health status. The internal consistency, test-retest reliability, and the convergent validity of the questionnaire were assessed.
Results:The prevalence of at least one weekly episode of grazing in general and LOC grazing was 71.1% and 54.5%, respectively. The internal consistence of the SIG was acceptable (0.81). In addition, SIG scores on both items were positively and significa ntly associated with BES, GAD7, and PHQ9 scores, and with poorer self-rated health.However, SIG scores on the test and retest differed significantly.
Conclusion:Overall, the Brazilian version of SIG demonstrated adequate psychometr ic properties. The instrument had an adequate internal consistency, with both items exhibiting good convergent validity with related measures.
The prevalence of binge eating spectrum conditions (BESC) are increasing globally. However, there is a lack of data from general population samples in low- and middle-income countries. Thus, this study described the food consumption during objective binge eating episodes (OBE) in people with BESC from a metropolitan city in Brazil. Participants comprised 136 adults (18 years old–60 years old) with Binge Eating Disorder (BED), Bulimia Nervosa (BN), or recurrent binge eating (RBE) from a two-phase epidemiological survey. They were interviewed in their homes by trained lay interviewers using the Questionnaire on Eating and Weight Patterns updated for the DSM-5 to assess BESC diagnosis and food consumption during a typical OBE. Overall, participants consumed a mean of 1067 kcal during the episodes. For the most part, these calories were derived from carbohydrates (58%) and lipids (30%), irrespective of the diagnosis. Regarding food item consumption, individuals with BED and RBE consumed staple foods (mainly rice and beans) more frequently than those with BN. Conversely, participants with BN ingested sugar-sweetened beverages more frequently than the BED group. In conclusion, there were differences in the eating patterns of individuals with BESC in Brazil. BED and RBE participants consumed more typical foods, whereas those with BN preferred foods with a high content of energy during their OBE.
