The Alcohol Use Disorders Identification Test (AUDIT) is an internationally well-established screening tool for the assessment of hazardous and harmful alcohol consumption. To be valid for group comparisons, the AUDIT should measure the same latent construct with the same structure across groups. This is determined by measurement invariance. So far, measurement invariance of the AUDIT has rarely been investigated. We analyzed measurement invariance across gender and samples from different settings (i.e., inpatients from general hospital, patients from general medical practices, general population).
A sample of n = 28,345 participants from general hospitals, general medical practices and the general population was provided from six studies. First, we used Confirmatory Factor Analysis (CFA) to establish the factorial structure of the AUDIT by comparing a single-factor model to a two-factor model for each group. Next, Multiple Group CFA was used to investigate measurement invariance.
The two-factor structure was shown to be preferable for all groups. Furthermore, strict measurement invariance was established across all groups for the AUDIT.
A two-factor structure for the AUDIT is preferred. Nevertheless, the one-factor structure also showed a good fit to the data. The findings support the AUDIT as a psychometrically valid and reliable screening instrument.
酒精使用障碍识别测试（AUDIT）是一种国际上广泛使用的评估危险和有害饮酒的筛查工具。为了进行组间比较，AUDIT 应该在不同组别中测量相同的潜在结构和相同的结构。这是通过测量不变性来确定的。迄今为止，AUDIT 的测量不变性很少被研究。我们分析了性别和来自不同环境（即综合医院的住院患者、普通医疗实践中的患者、普通人群）的样本的测量不变性。
从六项研究中提供了来自综合医院、普通医疗实践和普通人群的 n=28345 名参与者的样本。首先，我们使用验证性因子分析（CFA）通过比较每个组的单因素模型和双因素模型来确定 AUDIT 的因子结构。接下来，使用多组 CFA 来研究测量不变性。
对于所有组别，双因素结构都显示出更优。此外，AUDIT 在所有组别中均建立了严格的测量不变性。
AUDIT 的双因素结构更优。然而，单因素结构也显示出对数据的良好拟合。这些发现支持 AUDIT 作为一种具有心理测量学有效性和可靠性的筛查工具。
