This study aimed to evaluate the psychometric properties of the Italian version of the Eating Disorder Examination Questionnaire\u2014Short Form (EDE-QS) among 1912 workers undergoing health surveillance. Using an Item Response Theory framework, we tested dimensionality, reliability, and measurement invariance across gender, applying a graded response model to assess item discrimination and threshold parameters. Results supported an approximate unidimensional structure with excellent internal consistency (\u03c9 \u2248 0.95) and strong indices of factor score determinacy and construct replicability. Measurement invariance analyses indicated configural and metric invariance but not full scalar invariance, due to differential item functioning in a subset of items. Latent mean differences were small, with women scoring slightly higher than men, and associations with psychological, occupational, and health-related variables did not differ by gender. These findings indicate that the Italian EDE-QS shows promising structural validity as a brief measure of ED symptomatology in occupational samples in workplace contexts. However, gender-related item bias warrants cautious interpretation of specific behaviors, suggesting the need for tailored assessments to enhance diagnostic accuracy and inform preventive interventions.<\/jats:p>","DOI":"10.3390\/ejihpe16030037","type":"journal-article","created":{"date-parts":[[2026,3,5]],"date-time":"2026-03-05T14:19:21Z","timestamp":1772720361000},"page":"37","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Factor Structure and Measurement Invariance Across Gender of the Eating Disorder Examination Questionnaire\u2014Short Form in Italian Workers"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0988-7344","authenticated-orcid":false,"given":"Nicola","family":"Magnavita","sequence":"first","affiliation":[{"name":"Department of Safety and Bioethics, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1640-3897","authenticated-orcid":false,"given":"Carlo","family":"Chiorri","sequence":"additional","affiliation":[{"name":"Department of Educational Sciences, University of Genova, 16128 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1186\/s40337-018-0223-1","article-title":"Binge eating disorder and night eating syndrome in adults with type 2 diabetes: A systematic review","volume":"6","author":"Abbott","year":"2018","journal-title":"Journal of Eating Disorders"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"139","DOI":"10.2224\/sbp.2006.34.2.139","article-title":"Measuring happiness with a single-item scale","volume":"34","year":"2006","journal-title":"Social Behavior and Personality"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"21","DOI":"10.12681\/healthresj.22513","article-title":"The impact of mediterranean diet in perioperative nurses\u2019 health","volume":"6","author":"Agriopoulou","year":"2020","journal-title":"Health & Research Journal"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"91","DOI":"10.1002\/eat.24302","article-title":"Global and regional economic burden of eating disorders: A systematic review and critique of methods","volume":"58","author":"Ahmed","year":"2025","journal-title":"International Journal of Eating Disorders"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"716","DOI":"10.1109\/TAC.1974.1100705","article-title":"A new look at the statistical model identification","volume":"19","author":"Akaike","year":"1974","journal-title":"IEEE Transactions on Automatic Control"},{"key":"ref_6","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1016\/j.bodyim.2023.02.008","article-title":"Social physical anxiety and eating disorders: A systematic review and meta-analysis","volume":"45","author":"Paterna","year":"2023","journal-title":"Body Image"},{"key":"ref_7","doi-asserted-by":"crossref","first-page":"3215","DOI":"10.1007\/s40519-022-01452-0","article-title":"The prevalence and risk factors of screen-based disordered eating among university students: A global systematic review, meta-analysis, and meta-regression","volume":"27","author":"Alhaj","year":"2022","journal-title":"Eating and Weight Disorders"},{"key":"ref_8","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association (2022).
