通过将这些自我报告的暴露数据与整个工作日的观察数据进行比较，确定了估计暴露于任务、活动和躯干姿势的日记的有效性。研究对象是两个人群：32名职业司机和5名护士。在另一个工作日，护士和16名司机还填写了一份简短的日记。这两个版本的日记与同一时期的观察结果显示一致性很差。然而，对于与主干活动和姿势有关的变量，日记的缩短改善了协议。结论是，在流行病学研究中，暴露的观测测量不能有效地被日记或类似的自我报告的暴露数据所取代，因为自我报告容易导致错误的分类。
The validity of a diary that estimates exposure to tasks, activities, and postures of the trunk was determined by comparing these self-reported exposure data with observational data of a whole working day. Two populations were studied: 32 professional drivers and five nurses. The nurses and 16 drivers also filled out a shortened version of the diary during another working day. Both versions of the diary showed poor agreement with observations over the same period. However, for variables concerning activities and postures of the trunk agreement was improved by the shortening of the diary. It is concluded that in epidemiologic studies observational measurements of exposure cannot validly be replaced by diaries or similar self-reported exposure data, because the self-reports easily lead to misclassification.
