Abstract:

Ecological momentary assessment （ EMA ） is not a single research methods, but a paradigm. It emphasizes the real-time data collection and repeated assessment of the real world, and illustrates the relationship between the natural exist and change in variables. It has high ecological validity. The use of EMA can enhance our understanding of the active interaction between individuals and environment. The basic design idea of EMA includes Event-Based Designs 、Time-Based Designs and Combination Designs. In the use of EMA , researchers also need to pay attention to some problems such as the development of software and hardware , ethical problem ,and the data problem. At present, EMA is most widely applied in clinical psychology and behavior studies.

摘要：

生态瞬时评估（EMA）不是一个单一的研究方法，而是一种研究模式，它强调现实世界中实时数据的采集和反复的评估，并能阐释变量间自然存在和变化的相互关系，具有很高的生态学效度。EMA的使用会加强我们对个体与环境之间的动态交互作用的理解。EMA的基本设计思路包括基于事件的设计、基于时间的设计和联合设计。在EMA 的使用中还有一些问题如软硬件的发展、伦理、数据等问题等需要研究者注意。目前EMA应用最广泛的领域是临床心理学和行为研究方面。
