Advances in device-based measures have led researchers to question the value of reported measures of physical activity or sedentary behavior. The premise of the Workshop on Measurement of Active and Sedentary Behaviors: Closing the Gaps in Self-Report Methods, held in July 2010, was that assessment of behavior by self-report is a valuable approach.
To provide suggestions to optimize the value of reported physical activity and sedentary behavior, we 1) discuss the constructs that devices and reports of behavior can measure, 2) develop a framework to help guide decision-making about the best approach to physical activity and sedentary behavior assessment in a given situation, and 3) address the potential for combining reported behavior methods with device-based monitoring to enhance both approaches.
After participation in a workshop breakout session, coauthors summarized the ideas presented and reached consensus on the material presented here.
To select appropriate physical activity assessment methods and correctly interpret the measures obtained, researchers should carefully consider the purpose for assessment, physical activity constructs of interest, characteristics of the population and measurement tool, and the theoretical link between the exposure and outcome of interest.
基于设备的测量方法的进步使得研究人员开始质疑所报告的身体活动或久坐行为测量值的价值。2010 年 7 月举行的“积极和久坐行为测量方法研讨会：弥合自我报告方法差距”的前提是，通过自我报告评估行为是一种有价值的方法。
为了优化所报告的身体活动和久坐行为的价值，我们 1）讨论设备和行为报告可以测量的结构，2）制定一个框架，以帮助指导在特定情况下进行身体活动和久坐行为评估的最佳方法决策，3）解决将报告的行为方法与基于设备的监测相结合以增强这两种方法的潜力。
在参加研讨会分组讨论后，作者总结了提出的想法，并就此处呈现的内容达成了共识。
为了选择适当的身体活动评估方法并正确解释获得的测量值，研究人员应仔细考虑评估的目的、感兴趣的身体活动结构、人群和测量工具的特征，以及感兴趣的暴露和结果之间的理论联系。
