This study examined the psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) among a diverse sample of Brazilian college students. Specifically, the objectives of the present study were; (i) to examine the factor structure of AUDIT through confirmatory factor analysis and network analysis, (ii) to assess invariance of gender, sexual orientation and university (private vs. public, field of study), and relationship status; using multigroup confirmatory factor analysis, and (iii) to evaluate convergent, criterion, discriminant, and predictive validity. A total of 2,252 college students completed a sociodemographic questionnaire, the AUDIT, and additional measures of harmful alcohol consumption. The findings revealed that the three-factor AUDIT structure demonstrated the most robust fit and internal consistency across various student subgroups. Invariance was observed in all analyzed subgroups, with network analysis revealing consistent patterns of item clustering. The AUDIT also exhibited strong reliability (α = 0.817; ω = 0.827). The receiver operating characteristic curve analysis indicated that the optimal cutoff for harmful use was > 6, while it was > 7 for alcohol dependence, with the scores remaining consistent across diverse student subgroups. The AUDIT demonstrated robust correlations with the CAGE Questionnaire and total DSM-5 symptom scores (criterion validity), as well as with other measures of frequency of alcohol use (weekday and weekend) using timeline follow-back (convergent validity). A moderate correlation was observed for discriminant validity with attitudes towards alcohol use. The findings suggest that the AUDIT serves as a suitable instrument for screening potentially harmful alcohol use among diverse student subgroups.

这项研究调查了巴西大学生不同样本中酒精使用障碍识别测试（AUDIT）的心理测量特性。具体来说，本研究的目标是：(i) 通过验证性因素分析和网络分析来检查 AUDIT 的因素结构，(ii) 评估性别、性取向和大学（私立与公立、研究领域）以及关系状况的不变性；使用多组验证性因素分析，以及 (iii) 评估收敛效度、标准效度、判别效度和预测效度。共有 2,252 名大学生完成了社会人口调查问卷、审计以及有害饮酒的其他措施。研究结果表明，三因素审计结构在各个学生亚组中表现出最稳健的拟合度和内部一致性。在所有分析的子组中都观察到了不变性，网络分析揭示了项目聚类的一致模式。审计也表现出很强的可靠性（α = 0.817；ω = 0.827）。接受者操作特征曲线分析表明，有害使用的最佳截止值> 6，而酒精依赖的最佳截止值> 7，不同学生亚组的分数保持一致。审计证明了与 CAGE 问卷和总DSM-5症状评分（标准有效性）以及使用时间线追踪（收敛有效性）的其他饮酒频率指标（工作日和周末）之间的强大相关性。观察到判别有效性与饮酒态度存在中等相关性。研究结果表明，AUDIT 是筛查不同学生群体中潜在有害酒精使用情况的合适工具。
