Background/aim: Various new insulin delivery devices (e.g., insulin pumps, digital insulin pens, continuous subcutaneous insulin infusion) and features have been introduced over the last decade, and even more are in development. Despite their benefits, however, usage rates remain low. This study aimed to evaluate the validity and reliability of the Insulin Device Satisfaction Scale (IDSS) in the Turkish population.
Materials and methods: This cross-sectional methodological study included 150 patients with type 2 diabetes mellitus. Descriptive statistics, Cronbach's alpha, confirmatory factor analysis, and test-retest correlation were used for reliability and construct validity analyses.
Results: The IDSS was first translated into Turkish by two experts, then sent to a committee of 9 experts for content validity analysis. The total Cronbach's alpha value of the scale was 0.763. Goodness-of-fit indicators of the scale model were χ2 = 126.96, χ2/sd = 2.59, root mean square error of approximation = 0.076, comparative fit index = 0.90, incremental fit index = 0.91, non-normed fit index = 0.91, and normed fit index = 0.91.
Conclusions: Our findings demonstrate that the Turkish version of the IDSS is valid and reliable in the Turkish population. The IDSS can be used in nursing research and practice to evaluate Turkish patients' satisfaction with insulin devices.
