Hatoum AH, Burton AL, Berry SL, Abbott MJ. Psychometric properties of self-report measures of eating disorder cognitions: a systematic review. J Eat Disord 2023; 11:233. [PMID: 38124134 PMCID: PMC10734145 DOI: 10.1186/s40337-023-00947-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 12/04/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Although eating disorder (ED) models display some differences in theory and treatment approach, cognitive-behavioural, schema-focused, and disorder-specific models all highlight the fundamental nature of cognitions as key factors in ED development and maintenance processes. As such, it is vital that ED cognitions continue to be assessed and monitored as therapeutic targets and treatment outcomes as well as being examined as constructs in empirical research. This review aimed to systematically identify and evaluate the psychometric properties of existing self-report measures of ED cognitions. METHODS A systematic review protocol was registered using the international prospective register of systematic reviews (PROSPERO; CRD42023440840). Included studies described the development, validation and/or the psychometric evaluation of a measure (or subscale) that was specifically developed to solely assess ED cognitions (that is thoughts, expectations, assumptions, or beliefs), in English-speaking, adult populations. The search was conducted using three electronic databases: PsycINFO, MedLine, and Embase. Two independent reviewers conducted screening, selection and evaluation of the psychometric properties of relevant measures using a standardised, well-established quality appraisal tool. RESULTS Of the initial search of 7581 potential studies, 59 met inclusion criteria and described the psychometric evaluation of 31 measures (or subscales) of ED cognitions. The findings from the current review indicate that of the included measures, none currently meet all nine criteria of adequate psychometric properties. The Eating Beliefs Questionnaire (EBQ; and EBQ-18), and the Eating Disorder Inventory Body Dissatisfaction subscale (EDI [BD]) currently possess the most evidence supporting their validity, reliability, and clinical utility. CONCLUSIONS The findings of the current systematic review provide guidance for future researchers to focus efforts on improving evidence for the validity, reliability and utility of self-report measures of ED cognitions. Overall, the present study has provided a detailed and systematic evaluation to support researchers and clinicians in future selection of measures of ED cognitions dependent on the specific aims of their research and treatment.

Abstract
OBJECTIVE The aim of this study was the cross-cultural adaptation of the Eating Belief Questionnaire (EBQ)-an instrument that assesses positive, negative, and permissive eating beliefs in relation to binge eating episodes-in its shorted version of 18 questions, into Brazilian Portuguese, for female teenagers. METHODS Conceptual, semantic, cultural and operational equivalence of the items were evaluated. The semantic and cultural equivalence involved 12 bilingual people and 12 experts in eating behavior. Operational equivalence consisted of applying the transcultural adapted version of the EBQ-18 to 20 girls with a mean age of 17.55 (SD=1.00) years. Item's clarity and understanding were assessed by the Content Validity Coefficient. RESULTS Questions 5, 6, 11, 14, 15, 16, 17 and 18, with adequate classification percentage for all equivalences, were not altered. The other items were adapted according to the committee's suggestions and by consensus among researchers. The adapted version of the EBQ-18 in Brazilian Portuguese displayed good content validity coefficient for clarity (CVC=0.975) and comprehension (CVC=0.971); except for item 3, all items had values between 0.88 and 1.00. CONCLUSION The Brazilian Portuguese version of the EBQ-18 had a good understanding by the adolescent public when it comes to investigate the role of dietary beliefs in the maintenance of binge eating episodes. Future studies with adolescents are recommended, jointly assessing risk for and presence of eating disorders in significant clinical and non-clinical samples, as well as its psychometrics properties.

Abstract
PURPOSE The COVID-19 pandemic has been a leading cause of stress and feelings of loss of control, both of which have been related to eating disorder (ED) pathology onset and deterioration. We aim to estimate the magnitude of changes in the prevalence rates of, and indicators for, ED psychopathology in the face of the COVID-19 pandemic. METHOD Pre-registered systematic review with frequentist and Bayesian meta-analyses. Searches for eligible studies were performed in PubMed, Web of Science and pre-print servers until January 15 2023. RESULTS Our searches yielded 46 eligible studies reporting on a total of 4,688,559 subjects. These data provide strong evidence indicating increased rates of diagnosed and self-reported ED's and a concordant increased need for care in the face of the pandemic. ED symptom severity scores in patients were not elevated during the pandemic, except for those related to anorexia nervosa. On average, people in the general population report relatively high levels of emotional and binge eating during the pandemic, although the evidential strength for these associations is only anecdotal to moderate. Moderators of between-study heterogeneity were not detected. CONCLUSIONS Altogether, our results suggest that the COVID-19 pandemic is associated with a wide spread negative effect on ED pathology in patient samples and the general population. The development of online prevention and intervention programs for EDs during stressful times like a pandemic is encouraged. A limitation is that the results reported here may be prone to biases, amongst others, self-report bias. LEVEL OF EVIDENCE Level I, systematic review and meta-analysis.

Abstract
RESUMO Objetivo: Conduzir adaptação transcultural, para o português brasileiro, da versão reduzida de 18 questões do Eating Belief Questionnaire (EBQ) ao público de meninas adolescentes. O instrumento avalia crenças positivas, negativas e permissivas do comer com relação a episódios de compulsão. Métodos: Realizou-se avaliação das equivalências conceitual, semântica, cultural e operacional dos itens. A equivalência semântica e cultural envolveu 12 bilíngues e 12 especialistas em comportamento alimentar. A equivalência operacional consistiu na aplicação da versão transcultural adaptada do EBQ-18 em 20 meninas, com média de idade de 17,55 anos (DP=1,00). O grau de clareza e compreensão das questões foi avaliado pelo coeficiente de validade de conteúdo. Resultados: Na avaliação semântica e cultural, 8 itens tiveram classificação adequada para todas as equivalências e não sofreram alterações; 10 itens foram alterados de forma mínima, conforme sugestões dos especialistas e mediante consenso entre pesquisadoras; e apenas o item 3 sofreu adaptação após resultados da equivalência operacional. O modelo adaptado para o português apresentou bom coeficiente de validade de conteúdo para clareza (CVC=0,975) e compreensão (CVC=0,971); com exceção do item 3, todos os itens foram avaliados com valores entre 0,88 e 1,00. Conclusão: A versão em português do EBQ-18 apresentou-se com boa compreensão do público adolescente para investigação do papel de crenças alimentares na manutenção de episódios de compulsão. Recomendam-se trabalhos futuros avaliando conjuntamente risco e presença de transtornos alimentares em amostras significativas clínicas e não clínicas, bem como suas propriedades psicométricas.

Abstract
OBJECTIVE Distress tolerance (DT) has been found to be implicated in the development and maintenance of depressive symptomatology and various other significant psychological conditions. As such, it is critical to have measures of DT that are effective and easy to administer. This study aimed to examine the factor structure, psychometric properties, and clinical utility of the Distress Tolerance Scale (DTS) and the short-form version, the Distress Tolerance Scale Short-form (DTS-SF), in a large population of individuals with varying levels of self-reported depressive symptoms. METHOD A total of 959 participants completed an online battery of questionnaires which included an assessment of depressive symptoms as well as the DTS and related measures. Results: Confirmatory factor analyses validated the four-factor structure of the DTS and the one-factor structure of the DTS-SF. Good construct validity and good internal consistency were observed across both the DTS and DTS-SF. CONCLUSION Overall, this paper provides new evidence for the validity, reliability and discriminative ability of the DTS and the brief version of the questionnaire, the DTS-SF.

Abstract
PURPOSE Theoretical research on the psychological underpinnings of weight management is limited. Recently, the clinical obesity maintenance model (COMM) proposed a theoretical conceptualisation of salient psychological and neuropsychological mechanisms maintaining weight management issues. The current study aimed to empirically test the COMM and elucidate the results in the context of recent empirical findings. METHODS Participants (N = 165) were recruited from university and community settings in Australia. The sample consisted of adults with normal weight (n = 41), overweight (n = 40), and obesity (n = 84). Participants completed self-report questionnaires and a brief neuropsychological test. Structural equation modelling was used to estimate the associations between the hypothesised variables of the COMM and evaluate the model fit. RESULTS Findings suggested acceptable to good model fit. Furthermore, several direct effects were found. First, cognitive flexibility directly affected eating habit strength. Second, eating habit strength directly affected eating beliefs. Third, eating beliefs directly affected emotion dysregulation. Fourth, emotion dysregulation directly affected depression and binge eating with depression partially mediating this relationship. Finally, depression directly affected binge eating. CONCLUSION This was the first study to empirically test the COMM. Overall, findings provide preliminary support for the COMM as a psychological model of weight management and highlight the underlying psychological and neuropsychological mechanisms that may contribute to weight management issues. As this study examined a simplified version of the COMM, future research should continue evaluating this model and consider incorporating these components into more holistic weight management models to improve long-term treatment outcomes.

Abstract
Background Metacognitive beliefs play an essential role in the maintenance of binge eating behavior. Examining the psychometric properties of tools in societies with different cultures than western societies can help with examining the external validity of those tools. This research aimed at standardization and validation of the Eating Beliefs Questionnaire (EBQ-18) in Iran. Materials and Methods Persian version of the EBQ-18 was produced through forward translation, reconciliation, and back translation. A total of 302 non-WEIRD nonclinical students were selected through convenience sampling method and completed a set of questionnaires, including the EBQ-18, Eating Attitude Test-16 (EAT-16), Difficulties in Emotion Regulation Scale-16 (DERS-16), Weight Efficacy Lifestyle Questionnaire-Short Form (SF), self-esteem scale, and self-compassion scale (SCS) short-form. The construct validity of the EBQ-18 was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test-retest reliability (2 weeks' interval) were used to evaluate the reliability. Data analysis was performed using LISREL (version 8.8) and SSPS (version 22) softwares. Results EBQ-18 and subscales were found to be valid and reliable measures, with high test-retest reliability and good internal consistency in the nonclinical sample. Cronbrash's Alpha coefficient, for the whole of scale, negative beliefs scale, Permissive Beliefs scale, and Positive Beliefs scale were gained. 96.,89.,90, and. 94 respectively. Intraclass correlations coefficient, for the whole of scale, negative beliefs scale, Permissive Beliefs scale, and Positive Beliefs scale were gained. 84.,78.,75, and. 87, respectively. In terms of convergent validity, EBQ-18 and subscales showed a significant positive correlation with selfreport measures of EAT-16 and DERS-16 (P < 0.01). EBQ-18 and subscales showed a negative correlation with self-compassion, self-esteem, and eating self-efficacy, thus demonstrated divergent validity with these constructs (P < 0.01). The results showed that three factors of negative beliefs, positive beliefs, and permissive beliefs had the goodness of fit indices (root mean square error of approximation = 0.08, normed fit index = 0.97, nonnormed fit index = 0.98, comparative fit index = 0.98, and standardized root mean square residual = 0.04). The results of this study support the EBQ-18 three-factor model. Conclusion These findings indicate that the EBQ-18 is a reliable measure of eating beliefs in the Iranian population. In addition, the study supplements the literature on the cross-cultural validity of this measure.

Abstract
Abstract. The Eating Beliefs Questionnaire (EBQ) is a valid and reliable self-report tool measuring positive and negative beliefs about binge eating. This study sought to further investigate the clinical utility of the EBQ using a clinical binge eating sample and a healthy control comparison group. Clinical participants were 74 individuals seeking treatment for eating disorders: 38 with bulimia nervosa and 36 with binge eating disorder. Healthy controls were 114 individuals recruited from the general community. Participants all completed a test battery that included the EBQ. Diagnoses of clinical participants were confirmed using the semi-structured interview, the Eating Disorders Examination, administered by a trained clinician. The EBQ and its subscales showed good internal consistency, and significant differences between the clinical and nonclinical groups were observed for EBQ total and subscales scores, but not between the two clinical groups. Receiver operating characteristic (ROC) curve analyses revealed optimal cutoff scores for the EBQ, which demonstrated excellent sensitivity, specificity, and positive and negative predictive values. Results from this study provide further evidence in support of the EBQ’s psychometric properties. Clinical cutoff scores can be used to assess severity of binge eating-related cognitions in both research and clinical settings.

[PMID: 30223500 PMCID: PMC6165353 DOI: 10.3390/nu10091306] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Revised: 09/12/2018] [Accepted: 09/12/2018] [Indexed: 02/03/2023] Open
Abstract
Binge eating is a core diagnostic feature of bulimia nervosa, binge eating disorder, anorexia nervosa binge/purge type, and is a common feature of "other specified" and "unspecified" feeding and eating disorders. It has been suggested that specific metacognitive beliefs about food, eating, and binge eating may play a key role in the maintenance of binge eating behaviour. The Eating Beliefs Questionnaire (EBQ-18) provides a brief self-report assessment tool measuring three types of metacognitive beliefs: negative, positive, and permissive beliefs about food and eating. This study aimed to build on past research by validating the factor structure and psychometric properties of the EBQ-18 using both a clinical and non-clinical sample. A sample of 688 participants (n = 498 non-clinical participants, n = 161 participants seeking treatment for an eating disorder, and n = 29 participants seeking treatment for obesity) completed a battery of questionnaires, including the EBQ-18 and other measures of eating disorder symptoms and relevant constructs. A subset of 100 non-clinical participants completed the test battery again after an interval of two-weeks, and 38 clinical participants completed the EBQ-18 before and after receiving psychological treatment for their eating disorder. A confirmatory factor analysis (CFA) was conducted and psychometric properties of this measure were assessed. The results of this study provide support for the three-factor model of the EBQ-18. In addition, the EBQ-18 was found to be a valid and reliable measure, with excellent internal consistency, good test-retest reliability in the non-clinical sample, and also demonstrated evidence of sensitivity to treatment in clinical samples with binge eating pathology. Receiver operating characteristic (ROC) curve analyses were used to identify optimal cut-off scores for the EBQ-18. This study provides valuable information about the utility of the EBQ-18 as a measure for use in both clinical and research settings.

Abstract
BACKGROUND The Eating Beliefs Questionnaire (EBQ) is a self-report assessment tool that measures positive and negative beliefs about food and eating that are believed to play a key role in maintaining binge eating behaviour that occurs in individuals with Bulimia Nervosa, Binge Eating Disorder and other atypical eating disorders. The present study aimed to further refine this measure with the addition of a third scale to assess permissive beliefs about eating, also thought to play a crucial role in the maintenance of binge eating. Permissive beliefs are defined as beliefs about eating that provide justification for the individual to engage in a binge eating episode. METHODS After consultation with the literature and endorsement from 10 experts in eating disorders, 19 permissive belief items were generated. Eight hundred eighty-three participants were recruited to complete a test battery online that included the EBQ and the new permissive items. RESULTS An exploratory factor analysis (n = 441) found a three-factor solution (positive, negative and permissive beliefs) explaining 63.4% of variance. A confirmatory factor analysis (n = 442) provided support for the three-factor model, with the data best supporting a shorter 18-item questionnaire. The revised scale demonstrated good internal consistency, as well as good convergent validity with measures of related eating disorder symptoms, emotional regulation, mood and anxiety. CONCLUSIONS With the addition of a third scale to measure permissive beliefs, the revised short-form of the EBQ offers clinicians and researchers a brief comprehensive tool for the measurement of positive, negative and permissive beliefs about binge eating.

Abstract
BACKGROUND The aim of the present study was to test the validity, reliability and factor structure of the original Mindful Eating Questionnaire (MEQ) for use in an Iranian population. METHODS This was a cross-sectional study conducted on 150 women who attended four athletic gyms and met the inclusion criteria in Ahvaz city in July of 2015. After linguistic validation of the Iranian version of the MEQ, the content validity ratio (CVR) and content validity index (CVI) were assessed by an expert panel. Then, exploratory factor analysis (EFA) was performed on the scale constructs and scale reliability (internal consistency and test-retest reliability) was assessed with respect to the psychometric properties of the scale. RESULTS The CVR and CVI scores for the MEQ were 0.89 and 0.93, respectively. EFA loaded all 28-items with a 5-factor solution ('awareness', 'distraction', 'disinhibition', 'emotional response' and 'external cues') that jointly accounted for 53.78% of the observed variance. The results of the EFA supported the item 'When a restaurant portion is too large, I stop eating when I'm full' being placed in the external cues rather than the disinhibition subscale. This displacement improved the reliability coefficient for this subscale.The results of internal consistency analysis, including Cronbach's alpha (ranging from 0.73 to 0.81) and intraclass correlation coefficients (ranging from 0.73 to 0.91) were satisfactory. CONCLUSIONS The Persian version of the MEQ appears to be valid and reliable; therefore, it can be an effective tool in designing mindfulness-based interventions for the treatment of individuals with eating disorders, overweight and obesity in an Iranian population.
