Psychometric properties of the Comprehensive Diabetes Self-Management Scale in patient with diabetes

Abstract

This study’s objective was to investigate the psychometric characteristics of the “Comprehensive Diabetes Self-Management Scale,” which was created by Mikhael et al. This scale provides a comprehensive screening tool for health promotion-oriented behaviors. With the involvement of 475 diabetic people, the study was undertaken between January and August 2022. The study’s sample was formed by taking more than 33 times the amount of items on the original scale (14 items). “Diabetes Self-Care Scale” was used as a parallel form to calculate reliability coefficients. The scale’s confirmatory factor analysis showed a very good fit [x2 (53, N=475) p=0.014; x2/ degree of freedom=1.477; chi-square:78.276; root mean square error of approximation =0.032; comparative fit index =0.970; goodness-of-fit index =0.975] with the results obtained in the first level factorial structure of 13 items and five sub-dimensions. There was a 57.16% overall variance, it was found. The Comprehensive Diabetes Self-Management Scale was shown to be a valid and reliable measuring instrument for people with diabetes. This scale will provide the opportunity to evaluate many important concepts and behaviors related to diabetes with a single tool. © 2024 Elsevier B.V., All rights reserved.
