To ascertain the accuracy of a quantity-frequency questionnaire (QF) and a graduated frequency questionnaire (GF) as methods of obtaining self-reported alcohol intake in relation to a daily diary and biochemical tests.
QF and GF data were obtained before and after a 1-month daily diary on alcohol intake in a sample of 52 volunteers aged 20-63 years, of whom 43 were female. A blood sample to measure serum aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), gamma-glutamyltransferase (GGT) and % carbohydrate-deficient transferrin (CDT) was obtained at the outset.
Both QF and GF correlated closely with daily diary intake (r > 0.90). Compared with a daily diary, the mean QF intake was slightly lower, whereas the mean GF intake was 2-fold. The apparent overestimation by GF was independent of the actual consumption level. Self-reported alcohol intake by each method correlated closely with serum ASAT, ALAT and GGT (r = 0.41-0.67) but not with CDT.
In adults motivated to recall alcohol intake, both QF and GF classify individuals in the correct rank order, but GF probably overestimates actual alcohol consumption.
确定数量频率问卷（QF）和分级频率问卷（GF）作为获取自我报告饮酒量的方法相对于每日饮酒日记和生化检测的准确性。
在52名年龄在20 - 63岁的志愿者样本中，在为期1个月的每日饮酒日记前后分别获取QF和GF数据，其中43名女性。一开始采集血样以检测血清天冬氨酸转氨酶（ASAT）、丙氨酸转氨酶（ALAT）、γ-谷氨酰转移酶（GGT）和缺糖转铁蛋白百分比（CDT）。
QF和GF均与每日饮酒日记摄入量密切相关（r > 0.90）。与每日饮酒日记相比，QF的平均摄入量略低，而GF的平均摄入量是其2倍。GF明显的高估与实际消费水平无关。每种方法自我报告的饮酒量与血清ASAT、ALAT和GGT密切相关（r = 0.41 - 0.67），但与CDT无关。
在有动机回忆饮酒量的成年人中，QF和GF都能将个体按正确顺序分类，但GF可能高估了实际饮酒量。
