To review and categorize the problems associated with undertaking physical activity validation studies and to construct a checklist against which any study could be compared.
The studies reviewed demonstrated problems in defining the dimension of physical activity that is of interest and in the selection of an appropriate comparison technique. Ideally this should be closely related to the true exposure of interest and assess that exposure objectively and without correlated error from the study instrument in question. In many studies inappropriate comparison methods have been chosen which do not measure the true underlying exposure and which are likely to have correlated error. The choice of study populations, the frame of reference of the exposure measurement and the use of appropriate statistical methods are also problematic areas.
There is no ideal measurement instrument or validation study design that is suitable for all situations. However, the checklist in this paper provides a means whereby the appropriateness of studies already undertaken or at the planning stage can be assessed.
回顾并分类与进行体力活动验证研究相关的问题，并构建一个可供任何研究进行对照的清单。
所回顾的研究表明，在确定感兴趣的体力活动维度以及选择合适的比较技术方面存在问题。理想情况下，这应与真正感兴趣的暴露密切相关，并客观地评估该暴露，且不存在来自所讨论研究工具的相关误差。在许多研究中，选择了不恰当的比较方法，这些方法无法测量真正的潜在暴露，并且可能存在相关误差。研究人群的选择、暴露测量的参照系以及适当统计方法的使用也是存在问题的领域。
不存在适用于所有情况的理想测量工具或验证研究设计。然而，本文中的清单提供了一种手段，借此可以评估已开展的研究或处于规划阶段的研究的适宜性。
