Influential theoretical models hypothesize that alcohol use is an especially potent reinforcer when used as a strategy to cope with negative affect. Although the evidence for this idea in observational data is weak, some experimental evidence suggests that the behavioral economic demand for alcohol increases immediately following a negative emotional event. Because existing studies testing the effect of negative mood inductions on the demand for alcohol have several methodological limitations and do not take inter- and intraindividual variability into account, we developed an improved experimental design to increase our confidence in any potential within-person effect of negative mood inductions on alcohol demand as well as to test whether this effect exhibits systematic inter- and intraindividual variability. We hypothesize that people will show a higher demand for alcohol following negative compared to neutral mood inductions and that this effect is stronger in heavy compared to light drinkers as well as stronger on days characterized by higher coping motives and negative urgency. Three hundred twenty college students will complete the alcohol purchase task (APT) after being subjected to 100 mood inductions (six negative, six neutral) on 20 separate days.

有影响力的理论模型假设，当人们将饮酒作为应对负面情绪的策略时，酒精的使用尤其具有强烈的强化作用。尽管观察数据中这一观点的证据很薄弱，但一些实验证据表明，饮酒的行为经济学需求会在负面情绪事件发生后立即增加。由于现有的测试负面情绪诱导对酒精需求影响的研究存在一些方法学上的局限性，并且没有考虑到个体内和个体间的可变性，我们开发了一种改进的实验设计，以提高我们对负面情绪诱导对酒精需求的潜在个体内影响的信心，并测试这种影响是否表现出系统性的个体内和个体间可变性。我们假设，与中性情绪诱导相比，人们在负面情绪诱导后会表现出更高的酒精需求，并且这种影响在重度饮酒者中比轻度饮酒者更强，在以更高的应对动机和负面冲动为特征的日子里更强。320 名大学生将在 20 个不同的日子里接受 100 次情绪诱导（6 次负面，6 次中性）后完成酒精购买任务（APT）。（PsycInfo 数据库记录（c）2024 APA，保留所有权利）。
