AI 中文摘要
生态瞬时评估（EMA）广泛用于通过移动设备在参与者日常生活中收集重复的自我报告数据。EMA研究常涉及多问卷、灵活日程及纵向数据收集，现有的工作流程在工具间分散，难以复制和维护。我们提出了momenTUM，一个用于设计、部署和管理移动EMA研究的开源平台。其核心原则是结构化研究规范作为整个工作流程的共享表示。同一规范支持在研究设计器中编写、在面向参与者的移动应用中执行、后端同步和存储、与REDCap链接的数据处理以及研究人员监控。momenTUM与REDCap集成以自动设置项目并同步响应。其认证仪表板提供基于表格和日历的视图、按研究组件过滤以及可视化摘要。该平台已在实际研究中部署，包括研究双相情感障碍患者情绪、睡眠和昼夜节律的AMBIENT - BD以及EcoSleep队列研究。我们还描述了一种探索性的由大语言模型辅助的扩展，可为研究人员审查生成结构化研究规范草案。这些部署表明，momenTUM可以支持复杂的动态评估协议，同时减少技术开销并实现可重复、可复用和可扩展的EMA工作流程。
英文摘要
Ecological momentary assessment (EMA) is widely used to collect repeated self-report data in participants' everyday lives using mobile devices. EMA studies often involve multiple questionnaires, flexible schedules, and longitudinal data collection, requiring reliable systems for study setup, deployment, monitoring, and data management. Existing workflows are often fragmented across tools, making studies difficult to reproduce and maintain. We present momenTUM, an open-source platform for designing, deploying, and managing mobile EMA studies. Its central principle is that a structured study specification serves as the shared representation across the full workflow. The same specification supports authoring in the Study Designer, execution in the participant-facing mobile application, backend synchronization and storage, REDCap-linked data handling, and researcher monitoring. This makes protocols reusable, inspectable, and consistent across system components without requiring study-specific app implementations. momenTUM integrates with REDCap to automate project setup and synchronize responses. Its authenticated dashboard provides tabular and calendar-based views, filtering by study components, and visual summaries. The platform has been deployed in real-world studies, including AMBIENT-BD, which examines mood, sleep, and circadian rhythms in bipolar disorder, and the EcoSleep cohort study. We also describe an exploratory LLM-assisted extension that generates draft structured study specifications for researcher review. These deployments show that momenTUM can support complex ambulatory assessment protocols while reducing technical overhead and enabling reproducible, reusable, and extensible EMA workflows.
