Diary and weekly recall measures of alcohol consumption in a representative sample (N = 399) of the Dutch population are compared. The weekly recall method consisted of a personal interview with questions about actual alcohol consumption on the previous 7 days. The diary consisted of 14 daily self-reports of consumption and followed the interview. The diary method yields estimates of consumption that are on average 22% higher than those based on weekly recall measures, reducing total undercoverage by about 11%. The difference between the two methods cannot be attributed to a variation of consumption over weeks but seems to stem from a difference in accuracy of recall. There was an increase in glasses underreported at the upper levels of consumption, but underreporting did not seem to be of a nonlinear nature. Considering the large individual variation in consumption over weeks, the ranking of individuals according to their self-reports is relatively stable across method.
对荷兰人口代表性样本（N = 399）中酒精消费的日记法和每周回顾法进行了比较。每周回顾法包括一次个人访谈，询问前7天的实际酒精消费情况。日记法要求连续14天每日自我报告消费情况，且在访谈之后进行。日记法得出的消费估计值平均比基于每周回顾法的估计值高22%，使总漏报率降低了约11%。两种方法之间的差异不能归因于几周内消费情况的变化，而似乎源于回顾准确性的差异。在较高消费水平上，报告不足的杯数有所增加，但漏报似乎并非非线性的。考虑到几周内消费的个体差异较大，根据自我报告对个体进行的排名在不同方法之间相对稳定。
