目的：坚持抗逆转录病毒治疗对HIV管理和维持病毒抑制至关重要。尽管简化了治疗方案，但某些艾滋病毒感染者仍然难以坚持治疗。有证据支持使用移动健康应用程序在PLWH中进行有效的自我管理;然而，PLWH尚未开发和严格评估针对该人群的实时监测药物依从性应用程序。我们开发了一个用于艾滋病毒自我管理的mHealth应用程序（WiseApp），以帮助PLWH自我管理他们的健康。本研究的目的是评估WiseApp.Methods的可用性：我们进行了一个三步的可用性评估，使用1）一个传统的思考有声协议与最终用户，2）一个启发式的评估与信息学专家，和3）一个认知演练与最终用户。在认知演练期间，我们测试了两个与WiseApp关联的设备（健身追踪器和药物追踪瓶）。结果：有声思维协议通知了应用程序的迭代更新，特别是为了更容易地查看应用程序的不同部分。启发式评估证实了这些设计更改的必要性。认知演练通知额外的更新，并确认，总体而言，该应用程序和链接的设备是可用于最终users.Conclusion：与专家和最终用户的认知演练的结果通知迭代改进WiseApp和最终确定的移动健康应用程序PLWH更好地自我管理他们的健康。
Purpose: Adherence to antiretroviral therapy is essential to HIV management and sustaining viral suppression. Despite simplified regimens, adherence remains difficult for certain persons living with HIV (PLWH). There is evidence to support the use of mHealth apps for effective self-management in PLWH; however, a medication adherence app with real-time monitoring for this population has not been developed and rigorously evaluated by PLWH. We developed a mHealth app (WiseApp) for HIV self-management to help PLWH self-manage their health. The purpose of this study was to evaluate the usability of the WiseApp.Methods: We conducted a three-step usability evaluation using 1) a traditional think-aloud protocol with end-users, 2) a heuristic evaluation with experts in informatics, and 3) a cognitive walkthrough with end-users. During the cognitive walkthrough, we tested two devices (fitness tracker and medication tracking bottle) that were linked to the WiseApp.Results: The think-aloud protocol informed iterative updates to the app, specifically to make it easier to see different sections of the app. The heuristic evaluation confirmed the necessity of these design changes. The cognitive walkthrough informed additional updates and confirmed that overall, the app and the linked devices were usable for the end-users.Conclusion: The results of the cognitive walkthrough with both experts and end-users informed iterative refinements to the WiseApp and finalization of a mHealth app for PLWH to better self-manage their health.
