背景：酒精研究中经常使用许多不同的筛查测试，但我们对其中许多测试的可靠性的了解非常有限。最近，这个问题受到了更多的关注。本文检验了其中一种仪器——酒精使用障碍识别测试 (AUDIT) 在一般人群样本中的重测可靠性。方法：对一般人群样本 (n = 457) 进行了测试，并在大约 1 个月后使用 AUDIT 进行了重新测试。通过二分变量分析中的组内相关系数和 K 系数检验了两个检验之间的相关性。还使用第一次测试作为标准分析了许多不同截止分数的特异性和敏感性。结果：在项目级别上，相关性范围在 0.6 和 0.8 之间。 AUDIT 总分的总体可靠性为 0.84。按性别、年龄和消费者状况分层时，除低度酒精消费者 (0.51) 外，所有类别的总分可靠性约为 0.80。还检查了使用建议的截止分数 8+ 的一致性。在整个样本中观察到的可靠性 (K) 为 0.691，这被解释为基本一致。到此为止，与第一次测试相比，重新测试时的分类正确率为 91%。 AUDIT 8+ 对男性、年轻人和中等消费者的可靠性较高，而对低度消费者的可靠性较低。就可靠性而言，女性的最佳临界值是6或更多。结论：根据这些结果，AUDIT的重测可靠性很高。下一步可能是检查这些发现在多大程度上适用于医疗保健环境，这也是该测试最初设计的目的。
Background: A number of different screening tests are frequently used in alcohol research, but our knowledge about the reliability of many of them is quite limited. Recently, this problem has received more attention. This article examines the test-retest reliability of one of these instruments-the Alcohol Use Disorder Identification Test (AUDIT)-in a general population sample.Methods: A general population sample (n = 457) was tested and, after approximately 1 month, was retested by using the AUDIT. Correlation between the two tests has been examined with the intraclass correlation coefficient and the K coefficient in analysis of dichotomous variables. Specificity and sensitivity at a number of different cutoff scores have also been analyzed by using the first test as a criterion.Results: On the item level, the correlations ranged between 0.6 and 0.8. The overall reliability of total AUDIT scores was 0.84. When stratified by gender, age, and consumer status, the total score reliability approximated 0.80 for all the categories except low alcohol consumers (0.51). Agreement using the recommended cutoff score of 8+ was also examined. The reliability (K) observed in the whole sample was 0.691, which was interpreted as a substantial agreement. By this cutoff, 91% were correctly classified at retest compared with the first test. AUDIT 8+ showed higher reliability for males, young people, and moderate consumers and low reliability among low consumers. In terms of reliability, the most optimal cutoff for women turned out to be 6 or more.Conclusions: According to these results, the test-retest reliability of AUDIT is high. ne next step might be to examine to what extent the findings apply within health-care settings, which is what the test originally was designed for.
