本研究旨在进一步了解含咖啡因的酒精饮料（CAB）使用与酒精相关风险之间的关系。特别是，我们关注了CAB用途：中毒增强和避免负面后果这两个特定预期的作用。虽然结果预期是物质使用的一致预测因子，但有限的研究已经研究了与CAB使用相关的预期及其与酒精相关行为的关联，例如保护自己免受酒精相关伤害。因此，本研究探讨CAB的具体期望和保护性行为策略（PBS）的CAB使用和负面后果的介质。参与者是322（219名女性）大学饮酒者，他们完成了典型CAB和酒精使用，CAB特定预期，PBS使用和酒精相关危害的自我报告措施。结构方程模型显示，在控制典型的非CAB重度酒精使用后，通过避免负面后果CAB预期和PBS使用，CAB使用对酒精相关问题的显着间接影响。然而，中毒增强预期并没有介导这种关联。因此，我们的研究结果表明，大量使用CAB与饮用CAB有助于避免负面后果的强烈期望有关。这些信念与饮酒时使用较少的PBS和遇到问题的可能性更大有关。鉴于这些预期可能是CAB使用的潜在机制，将其纳入现有的酒精干预措施可能是有益的。
The present study sought to further understand the association between caffeinated alcoholic beverage (CAB) use and alcohol-related risks. In particular, we focused on the role of two identified expectancies specific to CAB use: intoxication enhancement and avoidance of negative consequences. Although outcome expectancies are consistent predictors of substance use, limited research has examined expectancies related to CAB use and their association with alcohol-related behaviors, such as protecting themselves from alcohol-related harms. Consequently, the present study examined CAB-specific expectancies and protective behavioral strategies (PBS) as mediators of CAB use and negative consequences. Participants were 322 (219 women) college drinkers who completed self-report measures of typical CAB and alcohol use, CAB-specific expectancies, PBS use, and alcohol-related harms. Structural equation modeling revealed, after controlling for typical non-CAB heavy alcohol use, a significant indirect effect of CAB use to alcohol-related problems through avoidance of negative consequences CAB expectancies and PBS use. However, intoxication enhancement expectancies did not mediate this association. Thus, our findings indicate that heavier CAB use was associated with stronger expectations that drinking CABs can help avoid negative consequences. These beliefs were related to using fewer PBS when drinking and a greater likelihood of experiencing problems. Given that these expectancies may be underlying mechanisms of CAB use, their inclusion in existing alcohol interventions may be beneficial.
