In this study participated 120 patients (39,2% women and 60,8% men) diagnosed with T2DM, whose average age was 59,7. Factor analysis found five factors, that explained 76,15% of the variance. Cronbach alphas were satisfactory and the instrument showed appropriate construct and discriminant validity.
