目的：审查和分类与进行身体活动验证研究相关的问题，并构建一个可以对任何研究进行比较的清单。结果：所审查的研究表明，在定义感兴趣的身体活动维度和选择适当的比较技术方面存在问题。理想情况下，这应该与感兴趣的真实暴露密切相关，并客观地评估该暴露，并且没有相关研究工具的相关误差。在许多研究中，选择了不适当的比较方法，这些方法不能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、暴露测量的参考框架以及适当统计方法的使用也是有问题的领域。结论：没有适合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方法，可以评估已经进行的或处于规划阶段的研究的适当性。
Objective: 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.Results: 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.Conclusions: 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.
