the distress experienced relating to climate change, is associated with mental health, yet no study has examined disordered eating related to eco-concern. This study developed and validated a 10-item scale assessing Eating-Related Eco-Concern (EREC). Participants (n = 224) completed the EREC, Climate Change Worry Scale (CCWS), and Eating Disorder Examination-Questionnaire (EDE-Q). Construct validity, convergent validity, and internal consistency were evaluated. Sex differences in EREC were evaluated using t-tests. Associations among the EREC, CCWS, and EDE-Q were evaluated using linear regression models. Sensitivity analyses were conducted in individuals below EDE-Q global score clinical cut-offs. Factor analysis suggested that all items loaded adequately onto one factor. Pearson\u2019s correlation and Bland\u2013Altman analyses suggested strong correlation and acceptable agreement between the EREC and CCWS (r = 0.57), but weak correlation and low agreement with the EDE-Q global score (r = 0.14). The EREC had acceptable internal consistency (\u03b1 = 0.88). No sex difference was observed in the EREC in the full sample; females had a significantly higher mean score than males in sensitivity analysis. The EREC was significantly positively associated with the CCWS and EDE-Q global and shape concern scores, but not in sensitivity analysis. The EREC is a brief, validated scale that can be useful to screen for eating-related eco-concern.<\/jats:p>","DOI":"10.3390\/nu14214517","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T22:36:17Z","timestamp":1666910177000},"page":"4517","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Development and Validation of an Eating-Related Eco-Concern Questionnaire"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0768-7055","authenticated-orcid":false,"given":"Baiyu","family":"Qi","sequence":"first","affiliation":[{"name":"Department of Epidemiology, University of North Carolina at Chapel Hill, Chapel Hill, NC 27516, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6854-1207","authenticated-orcid":false,"given":"Emily K.","family":"Presseller","sequence":"additional","affiliation":[{"name":"Department of Psychological and Brain Sciences, Drexel University, Philadelphia, PA 19104, USA"},{"name":"Center for Weight, Eating, and Lifestyle Science, Drexel University, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabrielle E.","family":"Cooper","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Avantika","family":"Kapadia","sequence":"additional","affiliation":[{"name":"Department of Clinical Psychology, National Institute of Mental Health and Neurosciences, Bangalore 560030, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2092-357X","authenticated-orcid":false,"given":"Alexis S.","family":"Dumain","sequence":"additional","affiliation":[{"name":"Department of Psychology and Neuroscience, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shantal M.","family":"Jayawickreme","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily C.","family":"Bulik-Sullivan","sequence":"additional","affiliation":[{"name":"Marsico Lung Institute and Cystic Fibrosis Research Center, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"},{"name":"Department of Cell Biology and Physiology, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric F.","family":"van Furth","sequence":"additional","affiliation":[{"name":"GGZ Rivierduinen Eating Disorders Ursula, 2333 ZZ Leiden, The Netherlands"},{"name":"Department of Psychiatry, Leiden University Medical Center, 2333 ZB Leiden, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9384-7988","authenticated-orcid":false,"given":"Laura M.","family":"Thornton","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7772-3264","authenticated-orcid":false,"given":"Cynthia M.","family":"Bulik","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"},{"name":"Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, 171 77 Stockholm, Sweden"},{"name":"Department of Nutrition, University of North Carolina at Chapel Hill, Chapel Hill, NC 27516, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9368-9457","authenticated-orcid":false,"given":"Melissa A.","family":"Munn-Chernoff","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,27]]},"reference":[{"key":"ref_1","unstructured":"(2022, October 18).
