Aim: The study deals with the linguistic validation and selected aspects (constructive validity and reliability) of the Insulin Delivery System Rating Questionnaire (IDSRQ).

Methods: The examined file consisted of 151 patients with type 1 diabetes mellitus. The linguistic and content validation IDSRQ was performed, and the results of the questionnaire and individual subscales were processed via descriptive statistics and factor analysis.

Results: The data was used to calculate the reliability of seven original subscales (0.42-0.92). Construct validity was tested via exploratory and confirmatory factor analysis. Models M1, M2 and M3, were created. For models M2 and M3, the significance of the chi-square test (p < 0.001) and FIT indices was calculated. The five-factor model with a reliability of 0.69-0.89 in subscales was identified as the best.

Conclusion: The new version of the questionnaire is in line with the psychometric properties of the original tool, and the extraction of items into a five-factor solution reflects the current assessment of patients' satisfaction with type 1 diabetes mellitus therapy in the Czech environment.
