To determine the reliability, validity, and responsiveness to change of AUDIT (Alcohol Use Disorders Identification Test) questions 1 to 3 about alcohol consumption in a primary care setting.
Randomly selected, male general medical patients (n = 441) from three VA Medical Centers, who had 5 or more drinks containing alcohol in the past year and were willing to be interviewed about their health habits.
Three self-administered AUDIT consumption questions were compared with a telephone-administered version of the trilevel World Health Organization interview about alcohol consumption.
Of 393 eligible patients, 264 (67%) completed interviews. Test-retest reliability--Correlations between baseline and repeat measures 3 months later for four dimensions of consumption according to the AUDIT, ranged from 0.65 to 0.85, among patients who indicated they had not changed their drinking (Kendall's Tau-b). Criterion validity--Correlations between AUDIT and interview for four dimensions of alcohol consumption ranged from 0.47 to 0.66 (Kendall's Tau-b). Discriminative validity--The AUDIT questions were specific (90 to 93%), but only moderately sensitive (54 to 79%), for corresponding criteria for heavy drinking. Responsiveness to change--The AUDIT consumption questions had a Guyatt responsiveness statistic of 1.04 for detecting a change of 7 drinks/week, suggesting excellent responsiveness to change.
AUDIT questions 1 to 3 demonstrate moderate to good validity, but excellent reliability and responsiveness to change. Although they often underestimate heavy alcohol consumption according to interview, they performed adequately to be used as a proxy measure of consumption in a clinical trial of heavy drinkers in this population.
确定在初级保健环境中，酒精使用障碍识别测试（AUDIT）中关于饮酒的问题1至3的可靠性、有效性以及对变化的反应性。
从三个退伍军人医疗中心随机选取的男性普通内科患者（n = 441），这些患者在过去一年中饮用含酒精饮料达5杯或更多，且愿意接受关于其健康习惯的访谈。
将三个自我管理的AUDIT饮酒问题与由电话进行的世界卫生组织三级饮酒访谈版本进行比较。
在393名符合条件的患者中，264名（67%）完成了访谈。重测信度——根据AUDIT，在表示饮酒习惯未改变的患者中（肯德尔Tau-b），3个月后基线测量与重复测量在饮酒四个维度上的相关性范围为0.65至0.85。效标效度——AUDIT与访谈在饮酒四个维度上的相关性范围为0.47至0.66（肯德尔Tau-b）。区分效度——AUDIT问题对于重度饮酒的相应标准具有较高的特异性（90%至93%），但敏感性仅为中等（54%至79%）。对变化的反应性——AUDIT饮酒问题在检测每周饮酒量变化7杯时的盖亚特反应性统计量为1.04，表明对变化具有出色的反应性。
AUDIT问题1至3显示出中等至良好的有效性，但具有出色的可靠性和对变化的反应性。尽管根据访谈结果，这些问题常常低估重度饮酒情况，但在该人群中重度饮酒者的临床试验中，它们作为饮酒量的替代测量方法表现良好。
