Caffeinated alcoholic beverage (CAB) consumption is a risky drinking practice for young people. The purpose of the current set of studies was to develop and psychometrically evaluate a theory-based CAB motives measure to understand what drives CAB consumption and its ensuing consequences. Using 4 different samples, we pilot tested the items of the Caffeinated Alcohol Beverages Motives Questionnaire (CABMQ) and then evaluated its factor structure and its convergent, concurrent, and discriminant validity. Factor analyses supported a 5-factor structure. The coping and conformity subscales assessed negative reinforcement from internal and external sources, respectively. The social subscale assessed positive reinforcement derived from external sources, whereas the intoxication and energy enhancement subscales assessed positive reinforcement derived from internal sources. Differential relationships between the intoxication and energy enhancement subscales and existing motives measures provided compelling support for their individual distinctiveness. Greater endorsement of all subscales was related to experiencing more adverse alcohol-related consequences, whereas all subscales but the conformity subscale were related to greater CAB consumption. After controlling for general drinking motives, coping motives, energy enhancement motives, intoxication enhancement motives, and social motives were significantly correlated with CAB use, whereas only energy enhancement motives were significantly correlated with alcohol-related consequences. In sum, these results show that the CABMQ helps us understand CAB use and its consequences, with the energy enhancement subscale being particularly helpful. Future research should examine if energy enhancement motives explain why CABs pose more risk than drinking alcohol on its own. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
饮用含咖啡因酒精饮料（CAB）对年轻人来说是一种危险的饮酒行为。当前这组研究的目的是开发并从心理测量学角度评估一种基于理论的CAB动机测量方法，以了解促使人们饮用CAB的原因及其产生的后果。我们使用4个不同的样本对含咖啡因酒精饮料动机问卷（CABMQ）的项目进行了预测试，然后评估了其因子结构以及收敛效度、同时效度和区分效度。因子分析支持了一个五因子结构。应对和从众子量表分别评估来自内部和外部来源的负强化。社交子量表评估来自外部来源的正强化，而醉酒和能量增强子量表评估来自内部来源的正强化。醉酒和能量增强子量表与现有动机测量方法之间的差异关系为它们各自的独特性提供了有力支持。所有子量表得分越高，与经历更多与酒精相关的不良后果相关，而除从众子量表外的所有子量表都与更高的CAB消费量相关。在控制了一般饮酒动机、应对动机、能量增强动机、醉酒增强动机和社交动机后，应对动机、能量增强动机、醉酒增强动机与CAB使用显著相关，而只有能量增强动机与酒精相关后果显著相关。总之，这些结果表明CABMQ有助于我们理解CAB的使用及其后果，其中能量增强子量表特别有帮助。未来的研究应该考察能量增强动机是否能解释为什么CAB比单独饮酒带来更多风险。（《心理学文摘数据库记录》（c）2021美国心理学会，保留所有权利）
