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.
目的 学校护士经常使用糖尿病设备，作为为1型糖尿病学生提供护理的一部分。本研究的目的是探讨希腊语版糖尿病设备信心量表（DDCS）的心理测量特性。方法 在这项横断面描述性研究中，143名学校护士完成了DDCS。这是一份自我管理的问卷，用于探究护士对使用糖尿病设备的信心。该量表根据世界卫生组织的指南进行了翻译和文化调适。组内相关系数和克朗巴赫α系数分别用于探究信度和内部一致性。通过探索性和验证性因素分析（EFA、CFA）对结构效度进行检验。数据通过社会科学统计软件包（SPSS）22.0版（美国纽约州阿蒙克市IBM公司）进行分析。结果 两次施测之间观察到显著相关性（p<0.001），表明该量表具有良好的信度（ICC = 0.525，p<0.001），而克朗巴赫α系数为0.966，表明具有出色的内部一致性。探索性因素分析得出一个一维解决方案，解释了总方差的53.7%。验证性因素分析表明该模型与数据拟合良好。结论 DDCS是一种可靠且有效的工具，可用于测试护士对糖尿病设备的信心。
