Design: 271 patients with celiac disease participated in this transversal descriptive study and completed a series of questionnaires regarding adherence (CDAT), general self-efficacy (GSES) and specific self-efficacy (Celiac-SE) and quality of life (CD-Qol), among others. Main Outcome Measures: Dependent variable was adherence to the Gluten Free Diet (GFD). Main independent variables were general self-efficacy, specific self-efficacy and quality of life. Model tests were conducted using regression analysis. Results: 71.9% of patients show an excellent or good adherence to the diet. Higher levels of adherence are positively associated to a high expectancy of specific self-efficacy, to the perceived adoption of recommended behaviours, risk perception and better quality of life (these variables accounted for 36.4% of the variance in the adherence to a GFD, p <.001). Conclusions: Specific self-efficacy rather than general has a predictive value in adherence to a GFD. Therefore, we need to develop and transculturally adapt new instruments to assess specific self-efficacy. Celiac-SE has proved to be a useful scale for this objective.2020http://zaguan.unizar.es/record/9569710.1080/08870446.2019.1675658http://zaguan.unizar.es/record/95697oai:zaguan.unizar.es:95697info:eu-repo/grantAgreement/ES/ISCIII/PI16-00570Psychology and Health 35, 6 (2020), 734-749All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
