The System Usability Scale (SUS) is the most commonly used questionnaire to assess usability of healthcare innovations but is not available in Dutch (D-SUS). This study aims to translate the SUS to Dutch and to determine its internal consistency, test-retest reliability, and construct validity in healthcare innovations focused on rehabilitation technologies.
Translation of the SUS was performed according to the WHO recommendations. Fifty-four participants filled out the D-SUS and Dutch Quebec User Evaluation of Satisfaction with assistive Technology (D-QUEST) twice. Internal consistency was assessed by Cronbach's alpha. Test-retest reliability was evaluated by Gwet's agreement coefficient (Gwet's AC2) on item scale, and Pearson correlation coefficient (PCC) for the overall D-SUS scores. Construct validity was assessed with the PCC between the D-SUS and D-QUEST overall scores (Netherlands Trial Register, ID: NL9169).
After translation, Cronbach's alpha was 0.74. Gwet's AC2 was 0.68 and the PCC between the first and second overall D-SUS scores was 0.75. No significant difference in D-SUS score between the two measurements was found. Repeatability coefficient was 18.4. The PCC between the D-SUS and D-QUEST overall scores was 0.49.
The D-SUS is a valid and reliable tool for usability assessment of healthcare innovations, specifically rehabilitation technologies.
系统可用性量表（SUS）是评估医疗保健创新可用性最常用的问卷，但在荷兰没有可用的版本（D-SUS）。本研究旨在将 SUS 翻译成荷兰语，并确定其在专注于康复技术的医疗保健创新中的内部一致性、重测信度和结构有效性。
根据世界卫生组织的建议对 SUS 进行翻译。54 名参与者两次填写 D-SUS 和荷兰魁北克辅助技术满意度问卷（D-QUEST）。内部一致性通过 Cronbach's alpha 评估。重测信度通过项目量表上的 Gwet 一致性系数（Gwet's AC2）和总体 D-SUS 评分的 Pearson 相关系数（PCC）进行评估。结构有效性通过 D-SUS 和 D-QUEST 总体评分之间的 PCC 进行评估（荷兰临床试验注册中心，ID：NL9169）。
翻译后，Cronbach's alpha 为 0.74。Gwet's AC2 为 0.68，第一次和第二次总体 D-SUS 评分之间的 PCC 为 0.75。两次测量的 D-SUS 评分无显著差异。重复性系数为 18.4。D-SUS 和 D-QUEST 总体评分之间的 PCC 为 0.49。
D-SUS 是一种用于评估医疗保健创新（特别是康复技术）可用性的有效且可靠的工具。
