N2 - Objective: The Self-Efficacy for Diabetes Scale (SED) is a widely used measure of diabetesspecific self-efficacy with three subscales: diabetes-specific self-efficacy (SED-D), medical self-efficacy (SED-M), and general self-efficacy (SED-G). The present study examined the factor structure and construct validity of the SED in 116 youth, aged 10-16 years (13.6061.87), with type 1 diabetes mellitus. Methods: Confirmatory factor analysis (CFA) was used to examine the factor structure of the SED. Correlational and regression analyses examined relations between subscales and select outcomes. Results: CFA of the original three-factor structure provided a poor fit to the data. Factor models using rescaled items were tested. Results: provided preliminary evidence for the SED-D as an independent one-factor model, and for a reduced one-factor model. Significant associations were found between the SED subscales, responsibility for diabetes management, and glycated hemoglobin. Conclusions: Results: provide limited support for the SED-D as a reliable and valid measure of diabetes-specific self-efficacy.
