A simple questionnaire to measure adherence to a gluten-free diet 2016 Access copy available to the general public Unrestricted Background and aims: A gluten-free diet is to date the only treatment available to celiac disease sufferers. However, systematic reviews indicate that, depending on the method of evaluation used, only 42% to 91% of patients adhere to the diet strictly. Transculturally adapted tools that evaluate adherence beyond simple self-informed questions or invasive analyses are, therefore, of importance. The aim is to obtain a Spanish transcultural adaption and validation of Leffler’s Celiac Dietary Adherence Test. Methods: A two-stage observational transversal study: translation and back translation by four qualified translators followed by a validation stage in which the questionnaire was administered to 306 celiac disease patients aged between 12 and 72 years and resident in Aragon. Factorial structure, criteria validity and internal consistency were evaluated. Results: The Spanish version maintained the 7 items in a 3-factor structure. Reliability was very high in all the questions answered and the floor and ceiling effects were very low (4.3% and 1%, respectively). The Spearman correlation with the self-efficacy and life quality scales and the self-informed question were statistically significant (p < 0.01). According to the questionnaire criteria, adherence was 72.3%. Conclusion: The Spanish version of the Celiac Dietary Adherence Test shows appropriate psychometric properties and is, therefore, suitable for studying adherence to a gluten-free diet in clinical and research environments. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 1.401 2016 GASTROENTEROLOGY & HEPATOLOGY 69 / 79 = 0.873 2016 Q4 T3 0.445 2016 Medicine (miscellaneous) 2016 Q2 Gastroenterology 2016 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gascón Santos, Santiago Universidad de Zaragoza (orcid)0000-0002-3723-0673 Asensio Martínez, Ángela Universidad de Zaragoza (orcid)0000-0001-5208-7556 Sánchez Calavera, María Antonia Universidad de Zaragoza (orcid)0000-0001-8756-114X Magallón Botaya, Rosa Universidad de Zaragoza (orcid)0000-0002-5494-6550 1006 255 Universidad de Zaragoza Dpto.
