The MedQ-Sus is a brief questionnaire that generates a Mediterranean Diet score and a Sustainable Diet score from the same eight food-group consumption data using different scoring criteria. Dietary intake was assessed using 3-day food records. Validity was evaluated by comparing the MedQ-Sus scores with corresponding food-group and nutrient intakes derived from the food records and by examining construct validity using a modified alternate Mediterranean Diet score (aMED) and the Planetary Health Diet Index (PHDI). Associations and agreement were assessed using Spearman correlation coefficients, Bland–Altman analysis, and intraclass correlation coefficients (ICCs) based on absolute agreement, as appropriate.

Bland-Altman analyses showed a mean difference of -5.5 ± 30.67 g, with limits of agreement wider for larger portions than for smaller portions. Absolute errors were lower for atlas-based estimations compared with self-estimation (p < 0.001). In the training phase, the mean relative portion placement error was 24.0 ± 19.3%, with food-specific values ranging from 15.4 ± 13.8% to 41.4 ± 29.2%.</p><p><strong>Conclusion: </strong>The developed photographic atlas demonstrated acceptable validity for dietary assessment and potential applicability in nutrition education.</p>","PeriodicalId":54803,"journal":{"name":"Journal of Human Nutrition and Dietetics","volume":"39 4","pages":"e70334"},"PeriodicalIF":2.3,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13491268/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148801820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
