许多患有心力衰竭的老年人很难遵循推荐的自我管理程序。为了帮助患有心力衰竭的老年人更有效地自我管理疾病，我们开发了 Engage，这是一款移动健康应用程序，旨在促进日常自我管理行为的表现、记录和共享。本文报告了对 15 名患有心力衰竭的老年人和非正式护理人员进行的 Engage 系统的可用性评估。参与者分两个阶段在基于任务的可用性测试 (n=5) 和基于场景的可用性测试 (n=10) 期间使用 Engage。通过视频记录观察以及系统可用性量表（SUS）和 NASA 任务负载指数（TLX）的管理来评估可用性和性能数据。我们发现基于任务的测试对于快速识别应用程序中的问题很有用，但基于场景的测试从老年人那里得到了更有价值的反馈。对所使用的不同评估方法的比较以及对遇到的挑战的讨论为老年人移动医疗产品可用性测试的实践提供了多重启示。
Many older adults living with heart failure struggle to follow recommended self-management routines. To help older adults with heart failure more effectively and efficiently self-manage their disease, we developed Engage, a mobile health application promoting the performance, logging, and sharing of routine self-management behaviors. This paper reports on the usability evaluation of the Engage system with 15 older adults with heart failure and informal caregivers. In two phases, participants used Engage during a task-based usability test (n=5) and a scenario-based usability test (n=10). Usability and performance data were assessed through video-recorded observation and the administration of the system usability scale (SUS) and NASA Task Load Index (TLX). We found that task-based testing was useful in quickly identifying problems within our application, but scenario-based testing elicited more valuable feedback from older adults. A comparison of the different evaluation methods used and the discussion of the challenges encountered provide multiple implications for the practice of usability testing of mobile health products with older adults.
