Sci.","Behavioral Sciences"],"abstract":"<jats:p>Autonomous motivation may support healthy eating, whereas body-shape concerns may fuel controlled eating regulation; the two had not been examined jointly with Mediterranean diet adherence in Romanian adults. In this cross-sectional study, a convenience sample of 224 predominantly female (87.1%), university-educated Romanian adults completed the Body Shape Questionnaire-16B (BSQ-16B), the Regulation of Eating Behaviors Scale (REBS), and a Romanian-adapted 14-item Mediterranean Diet Adherence Screener (MEDAS). The theory-derived expectations were not preregistered. Fit of the six-factor REBS structure improved substantially when cross-loadings between adjacent regulations were allowed, though discriminant validity remained limited; a bifactor analysis supported the BSQ-16B total score. BSQ-16B scores were associated with introjected (\u03b2 = 0.65) and controlled regulation (\u03b2 = 0.54) but not with autonomous styles or adherence (\u03c1 = \u22120.03). Autonomous motivation was associated with adherence after adjustment (b = 0.63 points per standard deviation; 95% confidence interval 0.31\u20130.94), as was physical activity; in an exploratory subscale model, integrated regulation showed the strongest unique association. Body-shape concerns were coupled with internal pressure but showed little evidence of an association with MEDAS-assessed adherence, whereas autonomous regulation emerged as a relevant correlate. The findings are consistent with, but do not test, autonomy-supportive counseling.<\/jats:p>","DOI":"10.3390\/bs16091690","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T09:01:38Z","timestamp":1789981298000},"page":"1690","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Body-Shape Concerns, Eating Regulation, and Mediterranean Diet Adherence in a Romanian Convenience Sample: A Cross-Sectional Self-Determination Theory Perspective"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2725-5508","authenticated-orcid":false,"given":"Cristina","family":"Georgescu","sequence":"first","affiliation":[{"name":"Nutrition and Dietetics Program, Faculty of Pharmacy, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u0219, 540142 T\u00e2rgu Mure\u0219, Romania"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"}]},{"given":"Cristina","family":"Filip","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Environmental Chemistry, Faculty of Pharmacy, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u0219, 540139 T\u00e2rgu Mure\u0219, Romania"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Ada","family":"Moldovan","sequence":"additional","affiliation":[{"name":"Nutrition and Dietetics Program, Faculty of Pharmacy, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u0219, 540142 T\u00e2rgu Mure\u0219, Romania"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5715-5220","authenticated-orcid":false,"given":"Florina Daniela","family":"Ruta","sequence":"additional","affiliation":[{"name":"Department of Community Nutrition and Food Safety, Faculty of Medicine, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u0219, 540139 T\u00e2rgu Mure\u0219, Romania"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,19]]},"reference":[{"key":"ref_1","first-page":"e-GMJ2026-A02","article-title":"Mediterranean diet adherence, body mass index, and quality of life among young adults: A cross-sectional analysis","volume":"33","author":"Arslan","year":"2026","journal-title":"Galician Medical Journal"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"41","DOI":"10.55646\/jaren.2023.72623","article-title":"Examination of the relationship between eating behavior disorder and emotional eating behavior in university students","volume":"9","author":"Arslan","year":"2023","journal-title":"Journal of Academic Research in Nursing"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"289","DOI":"10.1111\/j.2517-6161.1995.tb02031.x","article-title":"Controlling the false discovery rate: A practical and powerful approach to multiple testing","volume":"57","author":"Benjamini","year":"1995","journal-title":"Journal of the Royal Statistical Society: Series B (Methodological)"},{"key":"ref_4","unstructured":"Bollen, K.
