OBJECTIVE Colleges maintain alcohol policies in response to student alcohol misuse, and sanctions for violating these policies often mandate students to attend alcohol education and/or counseling (Anderson & Gadaleto, 2021). Electronic Checkup to Go (e-CHUG) is a widely used online motivational intervention program that provides feedback to college students to encourage them to alter their drinking behaviors (eCheckup to Go, 2021). While measures included in e-CHUG have clear clinical utility, their psychometric properties have not been evaluated. The present study was designed to evaluate the factor structure and validity of the 18-item drinking motives scale included in the intervention. METHOD Participants were 3,546 students from a large public university who were mandated to complete e-CHUG (58% male, MAge = 19.06, SDAge = 1.35) between 2013 and 2021. Students completed a battery of measures, including questions regarding alcohol consumption, drinking motives and consequences, and the Alcohol Use Disorders Identification Test (AUDIT). RESULTS An exploratory factor analysis was conducted to investigate the structure of the drinking motives scale. Two factors were retained: The first factor represented coping motives, and the second factor represented a mixture of enhancement and social motives. Hierarchical regression analyses explored the associations between the retained drinking motives factors and alcohol-related variables. Both coping motives and enhancement/social motives positively and uniquely predicted drinking consequences and AUDIT scores. CONCLUSIONS This study provides support for the construct and incremental validity of e-CHUG's drinking motives measure and could have important implications for the consideration of drinking motives during e-CHUG interventions.

对强制性学生的 e-CHUG 饮酒动机量表的探索性因素分析。

目标 大学维持酒精政策以应对学生滥用酒精的情况，而对违反这些政策的制裁通常会要求学生参加酒精教育和/或咨询（Anderson & Gadaleto，2021）。Electronic Checkup to Go (e-CHUG) 是一种广泛使用的在线激励干预计划，为大学生提供反馈，鼓励他们改变饮酒行为（eCheckup to Go，2021）。虽然 e-CHUG 中包含的措施具有明确的临床实用性，但其心理测量特性尚未得到评估。本研究旨在评估干预措施中包含的 18 项饮酒动机量表的因素结构和有效性。方法 参与者是来自一所大型公立大学的 3,546 名学生，他们被要求在 2013 年至 2021 年间完成 e-CHUG（58% 男性，MAge = 19.06，SDAge = 1.35）。学生完成了一系列措施，包括有关饮酒、饮酒的问题动机和后果，以及酒精使用障碍识别测试 (AUDIT)。结果 通过探索性因素分析来研究饮酒动机量表的结构。保留了两个因素：第一个因素代表应对动机，第二个因素代表增强和社会动机的混合。分层回归分析探讨了保留的饮酒动机因素与酒精相关变量之间的关联。应对动机和增强/社会动机都积极且独特地预测了饮酒后果和审计分数。结论 本研究为 e-CHUG 饮酒动机测量的构建和增量有效性提供了支持，并且可能对 e-CHUG 干预期间考虑饮酒动机产生重要影响。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
