Intervention development can be accelerated by using wearable sensors and ecological momentary assessment (EMA) to study how behaviors change within a person. The purpose of this study was to determine the feasibility and acceptability of a novel, intensive EMA method for assessing physiology, behavior, and psychosocial variables utilizing two objective sensors and a mobile application (app). Adolescents (n = 20) enrolled in a 20-day EMA protocol. Participants wore a physiological monitor and an accelerometer that measured sleep and physical activity and completed four surveys per day on an app. Participants provided approximately 81 % of the expected survey data. Participants were compliant to the wrist-worn accelerometer (75.3 %), which is a feasible measurement of physical activity/sleep (74.1 % complete data). The data capture (47.8 %) and compliance (70.28 %) with the physiological monitor were lower than other study variables. The findings support the use of an intensive assessment protocol to study real-time relationships between biopsychosocial variables and health behaviors.
通过使用可穿戴传感器和生态瞬时评估（EMA）来研究个体行为如何变化，可以加速干预措施的开发。本研究的目的是确定一种新颖的、密集的EMA方法的可行性和可接受性，该方法利用两个客观传感器和一个移动应用程序（app）来评估生理、行为和心理社会变量。青少年（n = 20）参与了一项为期20天的EMA方案。参与者佩戴一个生理监测器和一个测量睡眠及身体活动的加速度计，并每天在app上完成四项调查。参与者提供了约81%的预期调查数据。参与者对腕部佩戴的加速度计的依从性为75.3%，这是身体活动/睡眠的一种可行测量方式（完整数据占74.1%）。生理监测器的数据采集率（47.8%）和依从性（70.28%）低于其他研究变量。这些发现支持使用密集评估方案来研究生物心理社会变量与健康行为之间的实时关系。
