OBJECTIVE The aim of this study was to compare data on both alcohol use and alcohol-related consequences between intensive longitudinal data collection and the retrospective Timeline Followback (TLFB) interview. METHOD Heavy drinking college students (n = 96; 52% women) completed daily reports across a 28-day period to assess alcohol use and positive and negative consequences of drinking. They returned to the lab at the end of this period to complete a TLFB assessing behavior over those same 28 days. First, t tests were used to compare variables aggregated across the full 28 days at the between-person level. Next, hierarchical linear modeling was used to examine within-person differences between methods for each variable in weekly and daily increments. RESULTS Many alcohol use and consequence variables were significantly different when derived from self-reports during TLFB versus daily reports. In contrast to prior work, we found that higher estimates of drinking were reported retrospectively on the TLFB than on the daily reports. In addition, discrepancies were greater on some variables for heavier drinkers and when more time had elapsed between the end of the daily reporting period and TLFB collection. CONCLUSIONS Recall of drinking behavior during TLFB and daily reports may differ in systematic ways, with discrepancies varying based on participant and methodological characteristics.

酒精使用和后果的评估：通过时间线回访访谈和每日报告收集的数据的比较

目的本研究的目的是比较密集的纵向数据收集与回顾性时间轴回溯（TLFB）访谈之间有关酒精使用和酒精相关后果的数据。方法大量饮酒的大学生（n = 96； 52％的女性）在28天内完成了每日报告，以评估饮酒和饮酒的正面和负面影响。在此期间结束后，他们返回实验室以完成TLFB评估在相同的28天内的行为。首先，使用t检验比较人际水平上整整28天汇总的变量。接下来，使用分层线性建模来检查每个变量在每周和每天的增量下人与人之间的差异。结果从TLFB期间的自我报告和每日报告得出的许多饮酒和后果变量显着不同。与以前的工作相比，我们发现TLFB上的回顾性饮酒报告比每日报告中的饮酒估计更高。此外，对于较重的饮酒者以及在每日报告期末与TLFB收集之间经过了更多时间之后，某些变量之间的差异更大。结论回顾TLFB期间的饮酒行为和每日报告可能以系统的方式有所不同，差异会因参与者和方法学特征而异。对于较重的饮酒者，以及在每日报告期末与TLFB收集之间经过了更多时间之后，某些变量之间的差异更大。结论回顾TLFB期间的饮酒行为和每日报告可能以系统的方式有所不同，差异会因参与者和方法学特征而异。对于较重的饮酒者，以及在每日报告期末与TLFB收集之间经过了更多时间之后，某些变量之间的差异更大。结论回顾TLFB期间的饮酒行为和每日报告可能以系统的方式有所不同，差异会因参与者和方法学特征而异。
