Greek School Nurses' Confidence With Diabetes Devices

Aim School nurses often use diabetes mellitus devices as part of the care provided to students with Type 1 Diabetes Mellitus. The aim of this study was to explore the psychometric properties of the Greek version of the Diabetes Devices Confidence Scale (DDCS). Methods In this cross-sectional, descriptive study, 143 school nurses completed the DDCS. This is a self-administered questionnaire exploring the nurses' confidence in the use of diabetes devices. The scale was translated and culturally adapted according to the WHO guidelines. The Intraclass Correlation Coefficient and Cronbach's Alpha Index were used to explore the reliability and internal consistency, respectively. The construct validity was tested via exploratory and confirmatory factor analysis (EFA, CFA). Data were analyzed via Statistical Package for the Social Sciences (SPSS), version 22.0 (IBM Corp., Armonk, NY, USA). Results Significant correlations were observed between the two administrations (p<0.001) indicating the good reliability of the scale (ICC = 0525, p<0.001) while Cronbach's Alpha was 0.966 suggesting excellent internal consistency. The EFA resulted in a unidimensional solution explaining 53.7% of the total variance. The CFA showed that the model presents good fit to the data. Conclusions The DDCS is a reliable and valid tool to test the nurses' confidence in diabetes devices.
