本研究的目的是调查：（a）急性酒精对延迟折扣的影响;（B）饮酒状态对延迟折扣的影响;以及（c）这些影响是否因奖励类型（酒精与金钱）而异。重度和轻度社交酒精使用者（n = 96）在受试者间双盲设计中随机接受0.4或0.6 g/kg的急性酒精剂量或安慰剂。延迟折扣的酒精和金钱奖励的测量使用双曲线模型，分数越高，表明更大的延迟折扣。折扣分数的方差分析表明奖励类型的主要影响，所有参与者都有较高的折扣分数酒精与金钱奖励。还观察到饮酒状态的主要影响，与轻度饮酒者相比，重度饮酒者的折扣分数更高。我们没有观察到急性饮酒对延迟折扣的主要影响，也没有观察到急性饮酒和饮酒状态与奖励类型之间的假设相互作用。我们的数据表明，重度饮酒者比轻度饮酒者对延迟奖励的价值折扣更大。因此，延迟折扣可能是社交饮酒者大量饮酒的一个有希望的标志。
The aim of this study was to investigate the following: (a) the effects of acute alcohol on delay discounting; (b) the effects of drinking status on delayed discounting; and (c) whether these effects differ according to reward type (alcohol vs. money). Heavy and light social alcohol users (n = 96) were randomized to receive either an acute dose of alcohol at 0.4 or 0.6 g/kg or placebo in a between‐subjects, double‐blind design. Delay discounting of alcohol and monetary rewards was measured using a hyperbolic model, with higher scores indicative of greater delay discounting. ANOVA of discount scores indicated a main effect of reward type, where all participants had higher discount scores for alcohol versus money rewards. A main effect of drinking status was also observed, where heavier drinkers had higher discount scores compared with lighter drinkers. We did not observe a main effect of acute alcohol use on delay discounting or the hypothesized interactions between acute alcohol use and drinking status with reward type. Our data suggest that heavier drinkers discount the value of delayed rewards more steeply than lighter drinkers. Delay discounting may therefore be a promising marker of heavy alcohol consumption in social drinkers.
