Abstract
Background: The increasing trend of diabetes patients requires lifestyle interventions to improve the self-management ability of these patients, and achieving this requires the use of valid tools in this field. This study aimed to determine the psychometric properties of the Comprehensive Diabetes Self-Management Scale (CDSMS) in patients with type 2 diabetes.
Methods: The present study was methodological research that was conducted in 2023. At the beginning of the work, the CDSMS questionnaire was translated into Persian using the standard translation-back translation method. Then, face validity, content validity, convergent validity, internal consistency, and instrument stability were determined. Data analysis was performed using descriptive statistics, Cronbach's alpha calculation, Kappa index, Pearson correlation coefficient, and intra-cluster correlation coefficient in SPSS software version 24.
Results: Based on the results, all the items of the instrument were retained. The total content validity index score of the Persian version of this questionnaire was 0.987. Also, the Kuder-Richardson and Kappa indices were 0.704 and 0.730, respectively. The level of agreement at two measurement times, two weeks apart, ranged from 0.503 to 0.990. The intra-cluster correlation index was also observed to be in the range of 0.625 to 0.952 and was significant (P < 0.001). The Cronbach's alpha coefficient of the instrument was also 0.83.
Conclusion: The results of the present study showed that the Persian version of the CDSMS questionnaire with 14 items has good validity and reliability and can be used to evaluate the self-management status of patients with type 2 diabetes in Iran.
