The psychometric properties of the Diabetes Self-Efficacy Scale in Saudis with type 2 diabetes

AimTo assess the psychometric properties of the Arabic version of the Diabetes Self-Efficacy Scale (A-DSES).DesignThis study used a cross-sectional design.MethodsThis study recruited 154 Saudi adults with type 2 diabetes at two primary healthcare centres in Riyadh, Saudi Arabia. Its instruments were the Diabetes Self-Efficacy Scale and the Diabetes Self-Management Questionnaire. The psychometric properties of the A-DSES were assessed for reliability, including internal consistency and validity using exploratory factor analysis, confirmatory factor analysis and criterion validity.ResultsThe item-total correlation coefficients were >0.30 for all items, ranging from 0.46 to 0.70. The Cronbach's alpha for internal consistency was 0.86. One factor was extracted from the exploratory factor analysis (self-efficacy for diabetes self-management), and the one-factor model showed an acceptable fit to the data in the confirmatory factor analysis. Diabetes self-efficacy levels were positively correlated with diabetes self-management skills (r = 0.40, p < 0.001), indicating criterion validity.ConclusionsThe results indicate that the A-DSES is a reliable and valid instrument for assessing self-efficacy related to diabetes self-management.Relevance to Clinical PracticeThe A-DSES could be used in clinical practice and research to provide a reference for assessing self-efficacy levels in areas of diabetes self-management.No Patient or Public ContributionParticipants were not involved in the design, conduct, reporting or dissemination plans of this research.
