背景和目的三个问题的酒精使用障碍识别测试（AUDIT-C）经常用于医疗保健筛查和有关酒精消费水平的简要建议。AUDIT-C评分（0-12）作为风险类别提供反馈，而不是实际酒精摄入量的估计值，这是行为改变的重要指标。该研究旨在（i）从以英国（UK）单位表示的扩展AUDIT‐C中开发一个连续指标（8克纯乙醇），提供同等的准确度，并提供每周饮酒量（EWAC）的直接估计值，以及（ii）使用分级频率（GF）评估EWAC的偏倚和误差调查问卷作为酒精消费的参考标准。设计基于全国代表性调查的横断面诊断研究。设置英格兰社区居住家庭。共22404名年龄≥16岁的家庭居民报告至少偶尔饮酒。测量计算机辅助个人访谈，包括（i）带有扩展回答项目的AUDIT问卷（“扩展AUDIT”）和（ii）GF。主要结果是：EWAC和GF之间的平均偏差<1 UK单位（偏差度量）;均方根偏差<2 UK单位（总误差度量）。次要结果是预测酒精消费量超过14和35 UK units.FindingsEWAC的曲线下工作特征面积与GF相比有0.2 UK units（95%CI = 0.08，0.4）的正偏差。偏离偏离：而平均误差为±11 UK单位/周[9.5，11.9]，在一半的参与者中，EWAC和GF之间的偏差在0和±2.1 UK单位/周之间。EWAC预测消费量超过14英国单位/周，曲线下面积明显更大（0.918 [0.914，0.923]）比AUDIT-C（0.870 [0.864，0.876]）或全面审计（0.854 [0.847，0.860]）。结论使用扩展AUDIT‐C的答案的每周饮酒量的新估计量满足目标偏差容限。在预测消费阈值时，它的准确性上级AUDIT-C和完整的10项AUDIT，使其成为扩展AUDIT-C的可靠补充，用于健康促进干预。
Background and AimsThe three‐question Alcohol Use Disorders Identification Test (AUDIT‐C) is frequently used in healthcare for screening and brief advice about levels of alcohol consumption. AUDIT‐C scores (0–12) provide feedback as categories of risk rather than estimates of actual alcohol intake, an important metric for behaviour change. The study aimed to (i) develop a continuous metric from the Extended AUDIT‐C expressed in United Kingdom (UK) units (8 g pure ethanol), offering equivalent accuracy, and providing a direct estimator of weekly alcohol consumption (EWAC) and (ii) evaluate the EWAC's bias and error using the graduated‐frequency (GF) questionnaire as a reference standard of alcohol consumption.DesignCross‐sectional diagnostic study based on a nationally‐representative survey.SettingsCommunity dwelling households in England.ParticipantsA total of 22 404 household residents aged ≥16 years reporting drinking alcohol at least occasionally.MeasurementsComputer‐assisted personal interviews consisting of (i) AUDIT questionnaire with extended response items (the ‘Extended AUDIT’) and (ii) GF. Primary outcomes were: mean deviation <1 UK unit (metric of bias); root‐mean‐square deviation <2 UK units (metric of total error) between EWAC and GF. The secondary outcome was the receiver operating characteristic area under the curve for predicting alcohol consumption in excess of 14 and 35 UK units.FindingsEWAC had a positive bias of 0.2 UK units (95% CI = 0.08, 0.4) compared with GF. Deviations were skewed: whereas the mean error was ±11 UK units/week [9.5, 11.9], in half of participants the deviation between EWAC and GF was between 0 and ±2.1 UK units/week. EWAC predicted consumption in excess of 14 UK units/week with a significantly greater area under the curve (0.918 [0.914, 0.923]) than AUDIT‐C (0.870 [0.864, 0.876]) or the full AUDIT (0.854 [0.847, 0.860]).ConclusionsA new estimator of weekly alcohol consumption, which uses answers to the Extended AUDIT‐C, meets the targeted bias tolerance. It is superior in accuracy to AUDIT‐C and the full 10‐item AUDIT when predicting consumption thresholds, making it a reliable complement to the Extended AUDIT‐C for health promotion interventions.
