项目摘要

Advancing the Science and Practice of Ecological Momentary Assessment PROJECT SUMMARY This proposal is submitted in response to the program announcement PAR-16-260, “Methodology and Measurement in the Social and Behavioral Sciences,” with the specific goal of improving measurement in real-time data capture of experiences. Ecological Momentary Assessment (EMA) is a family of techniques for repeatedly capturing self-reports while people go about their everyday lives, and is particularly useful for assessing subjective states. It aims to achieve accurate and granular measurement of symptoms, well-being, affect, beliefs, and the social and physical environment over time in natural contexts. Although EMA methods are widely used in behavioral, social, and medical research, there are critical gaps in our understanding that must be resolved for EMA methods to be optimally understood and applied. This proposal examines five issues to provide necessary conceptual information about EMA and practical tools for conducting rigorous, high-quality, and replicable EMA studies; it employs several novel approaches for achieving these goals. The main issues to be investigated include: understanding how respondents interpret and answer momentary questions by conducting real-time, qualitative interviews; determining how various EMA protocol factors (e.g., length of assessment, number of days of assessments) impact selection bias of respondents and influence momentary compliance, and the development of a tool for efficiently evaluating the impact of particular designs; testing a model for a new generation of EMA measurement tools using modern psychometric principles (Item Response Theory), and evaluating the possibility of computerized adaptive tests for EMA; examining a core feature of EMA – that EMA reports are less biased than recall reports – by comparing both types of self-reports with an objective standard; and, finally, experimentally examining factors that have been hypothesized to bias EMA reporting, based on the idea that the act of self-monitoring and reporting may influence the nature of reports (i.e., measurement reactivity).

推进生态瞬时评估的科学和实践项目摘要该提案是根据计划公告Par-16-260提交的：社会和行为科学，“以改进实时数据捕获的测量的具体目标经验。生态瞬时评估（EMA）是一种反复捕获自我报告的技术家族人们每天都在生活时，对于评估主观状态特别有用。它旨在实现症状，幸福感，情感，信念以及社会和身体环境的准确和细粒度测量随着时间的流逝，在自然背景下。尽管EMA方法广泛用于行为，社会和医学研究，但对于我们的理解中，必须解决EMA方法必须得到最佳理解和应用的关键差距。该提案考试五个问题，以提供有关EMA和实用工具的必要概念信息进行严格，高质量和可复制的EMA研究；它采用几种新颖的方法来实现这些目标。要调查的主要问题包括：了解响应如何解释和回答瞬间通过实时，定性访谈进行问题；确定各种EMA协议因素如何（例如评估，评估天数）影响响应的选择偏见并影响瞬时依从性，以及开发一种工具，以有效评估特定设计的影响；测试新的模型使用现代心理学原理（项目响应理论）生成EMA测量工具，并评估对EMA进行计算机化自适应测试的可能性；检查EMA的核心功能 - EMA报告较少比召回报告有偏见 - 通过将两种类型的自我报告与客观标准进行比较；最后，基于以下观点，可以从实验检查已假设的因素，以偏向EMA报告。自我监控和报告可能会影响报告的性质（即测量反应性）。
