背景：越来越多的患者使用移动健康(MHealth)应用程序来监控自己的健康状况，并对自己进行医疗问题的教育。尽管这类应用程序越来越受欢迎，但糟糕的设计和可用性往往会导致这些应用程序的持续使用效果不佳，进而导致对它们所针对的行为变化的坚持程度较差。这些设计问题的一个解决方案是应用程序开发人员在开发过程中使用以用户为中心的设计(UCD)原则来考虑用户的背景和需求。目的：本研究旨在展示一个案例研究，该应用程序使用虚拟人技术(VHT)来鼓励在50岁及以上的患者中进行结直肠癌(CRC)筛查。然后，我们回顾了UCD原则以及如何将它们纳入健康应用程序的开发。我们已经描述了在应用程序开发期间如何使用UCD进程。然后，我们讨论了传播研究人员、计算机科学家、临床医生和社区参与者在创建可信、可用、有效且目标受众可访问的mHealth应用程序中所扮演的独特角色。结果：UCD的原则贯穿于项目开发的整个过程，研究人员在所有阶段收集患者和提供者的反馈，并使用这些反馈来提高mHealth应用程序的可信度、可用性、有效性和可访问性。该应用程序的设计采用迭代过程，鼓励应用程序的反馈和改进，并允许来自不同领域的团队重新讨论主题和解决问题。结论：实施UCD过程有助于应用程序的开发，这不仅反映了跨学科的专业知识，也反映了患者的需求、愿望和关切。
BACKGROUND: Patients are increasingly using mobile health (mHealth) apps to monitor their health and educate themselves about medical issues. Despite the increasing popularity of such apps, poor design and usability often lead to suboptimal continued use of these apps and subsequently to poor adherence to the behavior changes at which they are aimed. One solution to these design problems is for app developers to use user-centered design (UCD) principles to consider the context and needs of users during the development process.OBJECTIVE: This study aimed to present a case study on the design and development process for an mHealth app that uses virtual human technology (VHT) to encourage colorectal cancer (CRC) screening among patients aged 50 years and above.METHODS: We have first provided an overview of the project and discussed its utilization of VHT. We have then reviewed UCD principles and how they can be incorporated into the development of health apps. We have described how we used UCD processes during the app's development. We have then discussed the unique roles played by communication researchers, computer scientists, clinicians, and community participants in creating an mHealth app that is credible, usable, effective, and accessible to its target audience.RESULTS: The principles of UCD were woven throughout the project development, with researchers collecting feedback from patients and providers at all stages and using that feedback to improve the credibility, usability, effectiveness, and accessibility of the mHealth app. The app was designed in an iterative process, which encouraged feedback and improvement of the app and allowed teams from different fields to revisit topics and troubleshoot problems.CONCLUSIONS: Implementing a UCD process contributed to the development of an app, which not only reflected cross-disciplinary expertise but also the needs, wants, and concerns of patients.
