生态瞬时评估在体力活动行为干预研究中的应用

Application of Ecological Momentary Assessment in the Behavior Intervention Research of Physical Activity

体力活动行为干预策略依赖于对身体活动及其相关因素的准确测量与评估,以往回顾性的身体活动报告存在回忆性偏差和个体认知偏向,基于加速度计的客观测量无法提供体力活动行为发生的背景以及与体力活动行为密切相关的情绪、心理等信息,可能导致对体力活动行为影响因素的理解产生偏差。生态瞬时评估(ecologicalmomentary assessment,EMA)可克服以上不足,可对体力活动行为及认知、情感、环境背景等相关信息进行多次动态实时评估,在体力活动行为干预研究领域的应用价值也引起了关注。研究从生态瞬时评估特征、设计方法、可行性、有效性、评估内容、应用现状等方面对生态瞬时评估在体力活动行为干预中的应用进行了综述和展望,以期有助于体力活动行为干预理论和实践的发展。

The physical activity behavior intervention strategy relies on the accurate measurement and evaluation of physical activity and related factors.Recall bias and individual cognitive bias are existed in previous retrospective physical activity reports,and the use of accelerometer cannot provide the background,emotion,psychological states and other information related to physical activity behavior,all of these limitations may result in misunderstanding in factors affecting physical activity.The application of Ecological Momentary Assessment (EMA) in researching physical activity behavior intervention has cause concern because EMA can perform multiple dynamic and real-time evaluations on physical activity behaviors and related information such as cognition,emotion,and environmental background.In order to promote the development of theory and practice in physical activity behavior intervention,this paper summarizes the application of EMA in physical activity behavior intervention from the aspects of EMA characteristics,methods,feasibility,validity,assessment and applications,and some prospects are also raised.
