Background: Smartphone self-monitoring of mood, symptoms, and contextual factors through ecological momentary assessment (EMA) provides insights into the daily lives of people undergoing psychiatric treatment. Therefore, EMA has the potential to improve their care. To integrate EMA into treatment, a clinical tool that helps clients and clinicians create personalized EMA diaries and interpret the gathered data is needed. Objective: This study aimed to develop a web-based application for personalized EMA in specialized psychiatric care in close collaboration with all stakeholders (ie, clients, clinicians, researchers, and software developers). Methods: The participants were 52 clients with mood, anxiety, and psychotic disorders and 45 clinicians (psychiatrists, psychologists, and psychiatric nurses). We engaged them in interviews, focus groups, and usability sessions to determine the requirements for an EMA web application and repeatedly obtained feedback on iteratively improved high-fidelity EMA web application prototypes. We used human-centered design principles to determine important requirements for the web application and designed high-fidelity prototypes that were continuously re-evaluated and adapted. Results: The iterative development process resulted in Personalized Treatment by Real-time Assessment (PETRA), which is a scientifically grounded web application for the integration of personalized EMA in Dutch clinical care. PETRA includes a decision aid to support clients and clinicians with constructing personalized EMA diaries, an EMA diary item repository, an SMS text message–based diary delivery system, and a feedback module for visualizing the gathered EMA data. PETRA is integrated into electronic health record systems to ensure ease of use and sustainable integration in clinical care and adheres to privacy regulations. Conclusions: PETRA was built to fulfill the needs of clients and clinicians for a user-friendly and personalized EMA tool embedded in routine psychiatric care. PETRA is unique in this codevelopment process, its extensive but user-friendly personalization options, its integration into electronic health record systems, its transdiagnostic focus, and its strong scientific foundation in the design of EMA diaries and feedback. The clinical effectiveness of integrating personalized diaries via PETRA into care requires further research. As such, PETRA paves the way for a systematic investigation of the utility of personalized EMA for routine mental health care.

用于精神病护理中个性化生态瞬时评估的基于 Web 的应用程序：PETRA 应用程序的以用户为中心的开发

背景：智能手机通过生态瞬时评估 (EMA) 对情绪、症状和情境因素进行自我监测，从而深入了解接受精神病治疗的人们的日常生活。因此，EMA 有可能改善他们的护理。要将 EMA 整合到治疗中，需要一种临床工具来帮助客户和临床医生创建个性化的 EMA 日记并解释收集到的数据。目的：本研究旨在与所有利益相关者（即客户、临床医生、研究人员和软件开发人员）密切合作，开发一个基于网络的应用程序，用于在专业精神科护理中实现个性化 EMA。方法：参与者是 52 名患有情绪、焦虑和精神障碍的患者和 45 名临床医生（精神科医生、心理学家和精神科护士）。我们让他们参与访谈、焦点小组和可用性会议，以确定 EMA Web 应用程序的要求，并反复获得关于迭代改进的高保真 EMA Web 应用程序原型的反馈。我们使用以人为本的设计原则来确定 Web 应用程序的重要要求，并设计了不断重新评估和调整的高保真原型。结果：迭代开发过程产生了实时评估个性化治疗 (PETRA)，这是一个基于科学的网络应用程序，用于将个性化 EMA 整合到荷兰临床护理中。PETRA 包括支持客户和临床医生构建个性化 EMA 日记的决策辅助工具、EMA 日记项目存储库、基于 SMS 文本消息的日记传递系统以及用于可视化收集的 EMA 数据的反馈模块。PETRA 被集成到电子健康记录系统中，以确保临床护理的易用性和可持续集成，并遵守隐私法规。结论：PETRA 旨在满足客户和临床医生对嵌入常规精神科护理的用户友好和个性化 EMA 工具的需求。PETRA 在这个共同开发过程中是独一无二的，它广泛但用户友好的个性化选项，它与电子健康记录系统的集成，它的跨诊断重点，以及它在设计 EMA 日记和反馈方面的强大科学基础。通过 PETRA 将个性化日记整合到护理中的临床效果需要进一步研究。因此，PETRA 为系统研究个性化 EMA 在常规心理保健中的效用铺平了道路。
