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.<\/jats:p>","DOI":"10.3390\/nu10091306","type":"journal-article","created":{"date-parts":[[2018,9,14]],"date-time":"2018-09-14T10:57:59Z","timestamp":1536922679000},"page":"1306","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Beliefs about Binge Eating: Psychometric Properties of the Eating Beliefs Questionnaire (EBQ-18) in Eating Disorder, Obese, and Community Samples"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6641-6442","authenticated-orcid":false,"given":"Amy L.","family":"Burton","sequence":"first","affiliation":[{"name":"School of Psychology, The University of Sydney, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6736-7937","authenticated-orcid":false,"given":"Deborah","family":"Mitchison","sequence":"additional","affiliation":[{"name":"Centre for Emotional Health, Department of Psychology, Macquarie University, North Ryde, NSW 2109, Australia"},{"name":"School of Medicine, Western Sydney University, Campbelltown, NSW 2560, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0296-6856","authenticated-orcid":false,"given":"Phillipa","family":"Hay","sequence":"additional","affiliation":[{"name":"School of Medicine, Western Sydney University, Campbelltown, NSW 2560, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brooke","family":"Donnelly","sequence":"additional","affiliation":[{"name":"School of Psychology, The University of Sydney, Sydney, NSW 2006, Australia"},{"name":"The Peter Beumont Eating Disorder Service, Royal Prince Alfred Hospital, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Thornton","sequence":"additional","affiliation":[{"name":"The Redleaf Practice, Wahroonga, NSW 2076, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janice","family":"Russell","sequence":"additional","affiliation":[{"name":"School of Psychology, The University of Sydney, Sydney, NSW 2006, Australia"},{"name":"The Peter Beumont Eating Disorder Service, Royal Prince Alfred Hospital, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jessica","family":"Swinbourne","sequence":"additional","affiliation":[{"name":"School of Psychology, The University of Sydney, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Basten","sequence":"additional","affiliation":[{"name":"Centre for Emotional Health, Department of Psychology, Macquarie University, North Ryde, NSW 2109, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mandy","family":"Goldstein","sequence":"additional","affiliation":[{"name":"Mandy Goldstein Psychology, Bondi Junction, NSW 2022, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Touyz","sequence":"additional","affiliation":[{"name":"School of Psychology, The University of Sydney, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maree J.","family":"Abbott","sequence":"additional","affiliation":[{"name":"School of Psychology, The University of Sydney, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association (2013).
