Abstract
AIM: To assess the psychometric properties of the Arabic version of the Diabetes Self-Efficacy Scale (A-DSES). DESIGN: This study used a cross-sectional design. METHODS: This 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. RESULTS: The 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. CONCLUSIONS: The results indicate that the A-DSES is a reliable and valid instrument for assessing self-efficacy related to diabetes self-management. RELEVANCE TO CLINICAL PRACTICE: The 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 CONTRIBUTION: Participants were not involved in the design, conduct, reporting or dissemination plans of this research.
