Theories of alcohol use disorder (AUD) have long suggested that alcohol's emotional rewards play a key role in reinforcing problematic drinking. Studies employing survey methods, in which participants recall and aggregate their experiences with alcohol in a single questionnaire, indicate that self-reported expectancies and motivations surrounding alcohol's emotional rewards predict problematic drinking trajectories over time. The current study is the first to combine laboratory alcohol-administration, ambulatory methods, and longitudinal follow-ups to assess whether alcohol's ability to enhance positive mood and reduce negative mood predicts later drinking problems. Sixty young heavy social drinkers (50% female) participated in laboratory-based alcohol-administration, attending both alcohol (target blood alcohol concentration [BAC] .08%) and no-alcohol laboratory sessions. Forty-eight of these participants also wore transdermal alcohol monitors and completed mood surveys outside the laboratory for 7 days. Participants reported on their drinking at 18-month follow-up (90% compliance). Controlling for baseline drinking, greater negative mood reduction from alcohol at baseline predicted more drinking problems at follow-up, an effect that emerged as consistent across methods capturing alcohol's emotional rewards in the laboratory, b = -.24, p = .02, as well as via ambulatory methods, b = -3.14, p = .01. Greater positive mood enhancement from alcohol, captured via laboratory methods, also predicted drinking problems, b = .16, p = .03, and binge drinking, b = 3.22, p = .02, at follow-up. Models examining drinking frequency/quantity were nonsignificant. Results provide support for emotional reward as a potential factor in the development of problematic drinking.

一项关于酒精对年轻人的情绪奖励和饮酒随时间推移的多模态纵向调查。

酒精使用障碍 (AUD) 的理论长期以来一直表明，酒精的情绪奖励在加剧有问题的饮酒方面起着关键作用。采用调查方法的研究表明，参与者在一份问卷中回忆和汇总他们的饮酒经历，表明围绕酒精情感奖励的自我报告期望和动机随着时间的推移预测了有问题的饮酒轨迹。目前的研究首次将实验室酒精管理、动态方法和纵向随访相结合，以评估酒精增强积极情绪和减少消极情绪的能力是否预示着以后的饮酒问题。60 名年轻的重度社交饮酒者（50% 为女性）参加了基于实验室的酒精管理，参加了两种酒精（目标血液酒精浓度 [BAC] . 08%) 和无酒精实验室会议。其中 48 名参与者还佩戴了经皮酒精监测仪，并在实验室外完成了为期 7 天的情绪调查。参与者在 18 个月的随访中报告了他们的饮酒情况（90% 的依从性）。控制基线饮酒，基线时酒精带来的负面情绪降低程度更大，预测后续的饮酒问题更多，这种效果在实验室中捕获酒精情绪奖励的方法中表现出一致，b = -.24，p = .02，如以及通过动态方法，b = -3.14，p = .01。通过实验室方法捕捉到的酒精带来的更积极情绪增强也预测了饮酒问题，b = .16，p = .03，和酗酒，b = 3.22，p = .02，在随访中。检查饮酒频率/数量的模型不显着。结果支持情绪奖励是导致问题饮酒的潜在因素。（PsycINFO 数据库记录 (c) 2020 APA，保留所有权利）。
