The field of digital health solutions (DHS) has grown tremendously over the past years. DHS include tools for self-management, which support individuals to take charge of their own health. The usability of DHS, as experienced by patients, is pivotal to adoption. However, well-known questionnaires that evaluate usability and satisfaction use complex terminology derived from human-computer interaction and are therefore not well suited to assess experienced usability of patients using DHS in a home setting.
This study aimed to develop, validate, and assess an instrument that measures experienced usability and satisfaction of patients using DHS in a home setting.
The development of the "Experienced Usability and Satisfaction with Self-monitoring in the Home Setting" (GEMS) questionnaire followed several steps. Step I consisted of assessing the content validity, by conducting a literature review on current usability and satisfaction questionnaires, collecting statements and discussing these in an expert meeting, and translating each statement and adjusting it to the language level of the general population. This phase resulted in a draft version of the GEMS. Step II comprised assessing its face validity by pilot testing with Amsterdam University Medical Center's patient panel. In step III, psychometric analysis was conducted and the GEMS was assessed for reliability.
A total of 14 items were included for psychometric analysis and resulted in 4 reliable scales: convenience of use, perceived value, efficiency of use, and satisfaction.
Overall, the GEMS questionnaire demonstrated its reliability and validity in assessing experienced usability and satisfaction of DHS in a home setting. Further refinement of the instrument is necessary to confirm its applicability in other patient populations in order to promote the development of a steering mechanism that can be applied longitudinally throughout implementation, and can be used as a benchmarking instrument.
在过去几年中，数字健康解决方案（DHS）领域发展迅猛。DHS包括自我管理工具，可支持个人掌控自身健康。患者体验到的DHS可用性对于其采用至关重要。然而，评估可用性和满意度的知名问卷使用源自人机交互的复杂术语，因此不太适合评估患者在家中使用DHS时的体验性可用性。
本研究旨在开发、验证和评估一种工具，以测量患者在家中使用DHS时的体验性可用性和满意度。
“家庭环境中自我监测的体验性可用性和满意度”（GEMS）问卷的开发遵循了几个步骤。第一步包括评估内容效度，通过对当前可用性和满意度问卷进行文献综述，收集陈述并在专家会议上进行讨论，然后翻译每个陈述并将其调整到普通人群的语言水平。这一阶段产生了GEMS的草稿版本。第二步包括通过对阿姆斯特丹大学医学中心的患者小组进行预测试来评估其表面效度。在第三步中，进行了心理测量分析并评估了GEMS的可靠性。
共有14个项目纳入心理测量分析，得出4个可靠的量表：使用便利性、感知价值、使用效率和满意度。
总体而言，GEMS问卷在评估家庭环境中DHS的体验性可用性和满意度方面证明了其可靠性和有效性。为了确认其在其他患者群体中的适用性，有必要对该工具进行进一步完善，以促进开发一种可在整个实施过程中纵向应用的指导机制，并可作为一种基准工具。
