Improving seniors’ NL might be particularly pertinent to enhance the quality of their diets. This study aimed to systematically design and validate a short seniors-oriented questionnaire as a screening tool to evaluate NL. We developed the Myths-NL questionnaire, composed of 10 widespread nutrition myths, and checked for its content and face validity. An observational cross-sectional study was conducted to explore the validity and the test–retest reliability, involving a community-dwelling group of 316 individuals aged 65 years and over. Construct validity was proved by establishing both discriminant and convergent validity. Cronbach a = 0.61 and Spearman r = 0.79 (p = 0.02) demonstrated internal consistency and test–retest reliability. Participants who had secondary/university studies scored significantly higher compared with those with primary (p < 0.001), and a significant linear relationship (R2 = 0.044, p = 0.001) with a positive slope (ß = 0.209) between Mediterranean Diet Adherence Screener (MEDAS) and Myths-NL scores was observed, proving construct validity. In conclusion, the Myths-NL questionnaire is a valid and reliable tool to screen NL in Spanish seniors and it might be useful as an assessment NL tool for designing and implementing lifestyle interventions to promote healthy eating. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.614 2021 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 45 / 182 = 0.247 2021 Q1 T1 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 71 / 210 = 0.338 2021 Q2 T2 ENVIRONMENTAL SCIENCES 100 / 279 = 0.358 2021 Q2 T2 0.814 2021 Pollution 2021 Q1 Health, Toxicology and Mutagenesis 2021 Q1 4.5 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Tamayo Dominguez, María Universidad de Zaragoza Sanclemente, Teresa Universidad de Zaragoza (orcid)0000-0002-5407-3876 2008 640 Universidad de Zaragoza Dpto.
