目的：比较近乎同期的饮酒报告和回顾报告，并确定是否可以对回顾报告应用简单的调整函数来纠正报告中的任何扭曲。方法：通过交互式语音应答(IVR)系统收集的日常饮酒报告汇总了30多份。90天和366天，并与用时间线追踪(TLFB)收集的相应回顾报告进行比较。对33名男性每个时期的IVR和TLFB报告中的五个消费变量进行了比较。结果：在所测试的五个变量中，有四个变量的报告方法存在显著差异。平均而言，与IVR相比，TLFB产生了对酒精消耗量的低估。与TLFB报告相关的低估并不取决于召回期限的长短。回归分析表明，两种报告方式之间的关系取决于所报告的饮料量，因此不能采用简单的。对TLFB数据进行线性度量，对通过IVR获得的接近实时的每日数据进行建模，更准确地得出结论：与汇总的每日报告相比，回溯性TLFB一致且显著低估了酒精消耗量。然而，这一低估在三个报告期内都是稳定的。除了一个例外，不能将简单的线性函数应用于TLFB的回溯性消费报告，以更准确地反映每日收集的IVR数据。这里提供的证据还表明，对TLFB的低报不仅仅是有意识地试图隐瞒消费的问题。
Objective: To compare near-concurrent and retrospective reports of alcohol consumption and to determine whether a simple adjustment function could be applied to the retrospective reports to correct any distortions in reporting. Method: Reports of daily alcohol consumption collected via an Interactive voice Response (IVR) system were aggregated over 30. 90 and 366 days and compared with the corresponding retrospective reports gathered with the Timeline Follow Back (TLFB). Comparisons of the IVR and TLFB reports for five consumption variables were made for each time period for 33 men. Results: Significant differences between reporting methods were found for four of the five variables tested. On average, the TLFB yielded air underestimate of alcohol consumption compared to the IVR. This underestimate associated with TLFB reports was not dependent on the length of the recall period. Regression analyses indicated that the relationship between the two modalities of reporting was dependent on the quantity of drinks reported, thus precluding the application of a simple. linear metric to the TLFB data to model near real-time daily data obtained through the IVR more accurately Conclusions: The retrospective TLFB consistently and significantly underestimated alcohol consumption compared to the aggregated daily reports. This underestimate, however, was stable across the three reporting periods. With one exception, no simple linear function could be applied to the retrospective TLFB consumption reports to more accurately reflect the IVR data gathered daily. Evidence presented here also suggests that underreporting on the TLFB is not simply a matter of consciously attempting to conceal consumption.
