2019
Introduction : D iabetes self-care activities is a complex regimen, that required an appropriate tools to asses. T he Summary of Diabetes Self-Care Activities (SDSCA) questionnaire is the most widely used tool for assess diabetes self-care activities. The study aimed to testing validity and reliability of the Bahasa Indonesia version of the SDSCA. Methods: The study applied a forward-backward translation strategy. A pretest and a validation study were conducted. The Bahasa Indonesia version of the SDSCA was reviewed by an expert panel for conceptual and content equivalence to the English version. Furthermore, forty-five and 125 patients with T2DM participated in the pretest and the validation study, respectively . The psychometric properties were evaluated in terms of internal consistency, content validity, concurrent validity, and construct validity. Results: The content validity index (CVI) and t he internal consistency (Cronbach’s alpha) were satisfactory, which are 0.98, and 0.72, respectively. The exploratory factor analysis revealed that SDSCA-I are consistent with the original English version. There are significant correlations between three subscales of SDSCA-I and the diabetes knowledge levels namely general diet (r = 0.274 , p = 0.002), physical activity (r = 0.269 , p = 0.002), and foot care ( r = 0.297, p = 0.001). SDSCA-I was significantly correlated with HbA1c values, in term of general diet (r = -0.205, p = 0.022) and self-monitoring of blood glucose (r = -0.265, p = 0.003). Conclusions: The translation and psychometric test of the SDSCA-I were satisfactory. The tool could assess the self-care activities of Indonesians with T2DM in all settings .
