Universidad de Zaragoza (orcid)0000-0002-0493-1641 Development and validation of a specific self-efficacy scale in adherence to a gluten-free diet 2018 Access copy available to the general public Unrestricted The aim of this study was to develop a scale to assess the levels of specific self-efficacy in order to enhance adherence to a gluten-free diet and the life quality of celiac patients. Celiac disease is a chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically predisposed people. The only treatment is a strict lifelong gluten-free diet. Within the framework of Social Cognitive Theory, expectation of self-efficacy is understood as the degree in which a person believes himself to be capable of performing a certain task (e.g., adhering to a gluten-free diet), a construct which has been widely studied in its relation with adopting healthy behaviors, but scarcely in relation to celiac disease. A validation study was carried out in various stages: preparation of the protocol; construction of the questionnaire and a pilot run with 20 patients; validation of the scale with 563 patients and statistical analysis. A 25-item scale was developed. Feasibility was excellent (99.82% of participants completed all the questions). Factorial analysis pointed to the existence of five factors that explained 70.98% of the variance with a Cronbach alpha of 0.81 for the scale overall and between 0.64 and 0.90 for each factor. The scale showed a Spearman''s Rho coefficient of 0.279 with the General self-efficacy Scale. This easily administered scale provides good psychometric properties for evaluating specific self-efficacy of celiac patients in adhering to treatment. It seeks to be the first scale that provides not only a measurement of specific self-efficacy in celiac disease, but also to determine its levels for each of the areas as a first step toward designing interventions of self-management and empowerment programs to cope with the disease. info:eu-repo/grantAgreement/ES/FEDER/Una manera de hacer Europa info:eu-repo/grantAgreement/ES/ISCIII/PI16-00570 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.129 2018 PSYCHOLOGY, MULTIDISCIPLINARY 40 / 137 = 0.292 2018 Q2 T1 0.997 2018 Psychology (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Magallón-Botaya, R.
