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 Binge eating within binge-eating disorder (BED) is a behaviour widely understood as a response to dietary restraint and emotion dysregulation. However, qualitative literature suggests that a wider range of functions of binge eating exist, with associations between functions of binge eating and adverse childhood experiences highlighted across this research. The present study sought to develop a scale to measure a wide range of functions of binge eating within BED. A secondary aim was to examine the relationship between these functions and adverse childhood experiences (ACEs). METHOD The researchers developed an initial item pool for the Functions of Binge Eating Scale (FBES) and invited experts within the eating disorder (ED) field (n = 22) to review the items. The refined item pool was administered online to adults with self-reported binge eating symptoms (N = 882), along with related measures to establish scale validity. RESULTS Exploratory and confirmatory factor analyses produced an eight-factor structure (emotion regulation, hedonic hunger, compensatory eating, numbness/dissociation, emotion expression, self-punishment, control, self-protection). The scale demonstrated good internal reliability and adequate construct and predictive validity. Results also showed that functions theoretically related to childhood maltreatment were predicted by ACEs. DISCUSSION Findings extend our understanding of the range of functions of binge eating experienced in BED. Additionally, findings indicate that type of adverse childhood experience predicts functions of binge eating. Initial validation of the FBES suggests that functions of binge eating are wider than previously understood. Accordingly, clinicians are encouraged to explore and target more complex processes which might perpetuate binge-eating behaviour.

Abstract
Permissive beliefs are considered the most proximal predictor of actual behavior. Whereas they have frequently been researched in substance-use disorders, the field of social networking sites (SNS) use is missing the investigation as to how relevant permissive beliefs might be in this context, what might be causal precursors of permissive beliefs (i.e., desire thinking), and which processes might influence the effect that permissive beliefs have on actual behavior (i.e., self-control). To answer these questions, 116 people who use SNS participated in an online survey that contained an experimental manipulation of desire thinking and questionnaires measuring permissive beliefs, self-control, and severity of problematic SNS use. In a one-week follow-up, 85 participants reported their SNS usage times. Results showed that the association between permissive beliefs and tendencies to use SNS problematically was not significant. The experimental manipulation led to a decrease in permissive beliefs in the control condition, but did not increase permissive beliefs in the desire thinking condition. Permissive beliefs predicted SNS use in the follow-up assessment, which was not moderated by self-control. The results suggest that permissive beliefs seem to be unrelated to addictive tendencies of SNS use, but are nevertheless associated with daily use. Desire thinking does not appear to activate permissive beliefs in this study, possibly because the use of social networks is less often experienced as conflicting. Due to its ubiquitous availability, the use of social networks itself might quickly resolve the conflict between desires and possible regulatory attempts, making good reasons for use unnecessary.

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
BACKGROUND Increased theoretical and empirical attention has been given to examining the role of core beliefs in both the development and maintenance of eating disorders (EDs). The Eating Disorder Core Beliefs Questionnaire (ED-CBQ) is self-report measure designed to assess five dimensions of core beliefs relating to eating disorders; self-loathing, unassertive/inhibited, demanding/needing help and support, abandoned/deprived, and high standards for the self. The present study aimed to evaluate the psychometric properties of the ED-CBQ and to develop a revised and improved version of the original measure after evaluating its factor structure and related properties. METHODS A sample of undergraduate university students (N = 763) completed an online test battery of questionnaires. Putative ED-symptomatic (n = 384) and non-ED (n = 379) subgroups were created from self-reported responses from the Eating Disorder Examination Questionnaire (EDEQ). Confirmatory factor analyses (CFAs) were performed, and internal consistency, construct validity, group differences and clinical utility was examined. RESULTS An initial CFA did not support the original five-factor 40-item ED-CBQ. A revised version was developed that possessed equal or superior psychometric properties to the original 40-item measure. The ED-CBQ-R demonstrated superior model fit, similar levels of reliability and construct validity, and the ability to discriminate between putative ED diagnostic groups. CONCLUSIONS Our results suggest that the ED-CBQ-R is a valid, reliable, but more importantly an efficient and accessible measure with the potential to be utilised both clinically and in research settings.

Abstract
Background: Screening for eating disorders via reliable instruments is of high importance for clinical and preventive purposes. Examining the psychometric properties of tools in societies with differing dynamics can help with their external validity. This research specifically aimed at standardization and validation of the eating attitude test (EAT-16) in Iran. Methods: The Persian version of the EAT-16 was produced through forward translation, reconciliation, and back translation. The current research design was descriptive cross-sectional (factor analysis). A total of 302 nonclinical students were selected through the convenience sampling method and completed a set of questionnaires. The questionnaires included, the EAT-16, eating beliefs questionnaire-18 (EBQ-18), difficulties in emotion regulation scale-16 (DERS-16), weight efficacy lifestyle questionnaire-short form, self-esteem scale, and self-compassion scale short-form. The construct validity of the EAT-16 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 conducted using LISREL (version 8.8) and SSPS (version 22) software. Results: EAT-16 and subscales were found to be valid and reliable, with good internal consistency and good, test–retest reliability in a non-clinical sample. In terms of convergent validity, EAT-16 and subscales showed a positive correlation with the selfreport measures of EBQ-18 and DERS-16. EAT-16 and subscales showed a negative correlation with self-compassion, self-esteem and eating self-efficacy., Therefore, it demonstrated divergent validity with these constructs. The results of this study support the EAT-16 four-factor model. Conclusions: The EAT-16 showed good validity and reliability and could be useful in assessing eating disorders in Iranian populations. The EAT-16 is an efficient instrument that is suitable for screening purposes in the nonclinical samples.

Abstract
BACKGROUND Eating disorders are complicated health problems that affect both the body and the mind. Eating disorders pose a serious challenge to mental health services because of their often chronic pathway. The current study was done to determine the psychometric properties of the Eating Disorder Examination Questionnaire Short Form (EDE-QS). MATERIALS AND METHODS Persian version of the EDE-QS was produced through forward-translation, reconciliation, and back-translation. The design of this research was cross- sectional. A sample of 302 Tehran university's students in 2019-2020 was selected through convenience sampling method and completed a set of questionnaires, including the EDE-QS, Eating Attitude Test (EAT-16), Eating Beliefs Questionnaire-18 (EBQ-18), Self-Esteem Scale (SES), and Self-Compassion Scale (SCS) Short Form. The construct validity of the EDE-QS was assessed using confirmatory factor analysis and divergent and convergent validity. Internal Consistency and test-retest reliability were conducted to evaluate the reliability. Data analysis was conducted using SPSS (version 22) software and LISREL (version 8.8). RESULTS EDE-QS was found to be valid and reliable measures, with good internal consistency and good test-retest reliability among students. Cronbach's alpha coefficient for the whole of scale was 0.85. Intraclass correlation coefficient for the whole of scale was 0.90. In terms of convergent validity, EDE-QS showed a significant positive correlation with self-report measures of EAT-16 and EBQ-18 (P < 05). EDE-QS showed a negative correlation with self-compassion and self-esteem, thus demonstrated a good divergent validity (P < 05). The results of this study also provide support for the one-factor model of the EDE-QS (root mean square error of approximation = 0.08, Normed Fit Index [NFI] = 0.90, Incremental Fit Index = 0.92, non-NFI = 0.90, and Comparative Fit Index = 0.92). CONCLUSION The EDE-QS showed good validity and reliability and could be useful in assessing eating disorder psychopathology in a nonclinical population of students. The EDE-QS shows notable promise as a measure for use in eating disorder research and clinical settings.

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
BACKGROUND There are a number of factors commonly believed to be important to the development and maintenance of binge eating that have been identified across multiple models and theories in the psychological literature. In the present study, we sought to develop and test a psychological model for binge eating that incorporated the main variables identified in the literature to drive binge eating behaviour; specifically, core low self-esteem, negative affect, difficulty with emotional regulation, restricted eating and beliefs about eating. METHODS Questionnaire data was collected from 760 unselected participants. The proposed model of binge eating was developed, bivariate relationships between the included variables were assessed, and the goodness-of-fit of this new model was evaluated using structural equations modelling. RESULT The results identified significant bivariate relationships between all the included variables. While the originally proposed model did not provide a good fit to the data, the revised version of the model provided a good fit to the data. CONCLUSIONS Supporting, integrating and building upon the current existing psychological models of binge eating, this study presents a new integrated cognitive and behavioural model of binge eating. The dual-pathway to binge eating identified in the new model provides a different way to understand transdiagnostic binge eating.
