StudyMe：一个用于以用户为中心的N-of-1试验的新移动应用程序
StudyMe: A New Mobile App for User-Centric N-of-1 Trials
摘要：
N-of-1试验是多交叉自我实验，允许个人系统地评估干预措施对其个人健康目标的影响。虽然存在用于N-of-1试验的几种工具，但没有一种支持非专家进行自己的以用户为中心的试验。在这项研究中，我们提出了StudyMe，一个开源的移动应用程序，可以从https://play.google.com/store/apps/details?免费获得id= health.studyu.me，并为用户提供配置其试验的每个组件的灵活性和指导。我们还提出了研究，通知StudyMe的发展。通过对272名参与者的初步调查，我们了解到，个人对各种个人健康方面感兴趣，并对如何改善这些方面有独特的想法。在一个迭代的、以用户为中心的开发过程中，我们开发了StudyMe，它还具有一个教育部分，用于传达N-of-1试验概念。StudyMe的最终实证评估显示，所有参与者都能够使用StudyMe成功创建自己的试验，并且该应用程序获得了非常好的可用性评级。我们的研究结果表明，StudyMe提供了一个重要的一步，使个人能够应用系统的科学为导向的方法，个性化的健康相关的干预措施和行为修改在他们的日常生活。
英文摘要：
N-of-1 trials are multi-crossover self-experiments that allow individuals to systematically evaluate the effect of interventions on their personal health goals. Although several tools for N-of-1 trials exist, none support non-experts in conducting their own user-centric trials. In this study we present StudyMe, an open-source mobile application that is freely available from https://play.google.com/store/apps/details?id=health.studyu.me and offers users flexibility and guidance in configuring every component of their trials. We also present research that informed the development of StudyMe. Through an initial survey with 272 participants, we learned that individuals are interested in a variety of personal health aspects and have unique ideas on how to improve them. In an iterative, user-centered development process with intermediate user tests we developed StudyMe that also features an educational part to communicate N-of-1 trial concepts. A final empirical evaluation of StudyMe showed that all participants were able to create their own trials successfully using StudyMe and the app achieved a very good usability rating. Our findings suggest that StudyMe provides a significant step towards enabling individuals to apply a systematic science-oriented approach to personalize health-related interventions and behavior modifications in their everyday lives.
