Impulsivity is associated with excessive drinking and negative alcohol-related consequences. However, studies have not used an in-vivo approach (i.e., daily diary) to examine how the effect of impulsivity on excessive alcohol use could be moderated by context-specific mechanisms, such as incentives.
The study recruited a sample of young adults ( = 102, 61.8% females), who, for two weeks, responded to questions about their total number of drinks and the incentives (alcohol incentives and social/party incentives) that influenced their decisions to drink. At baseline, participants completed a questionnaire assessing trait impulsivity.
The findings indicated a significant main effect of social/party incentives and alcohol incentives on the total number of drinks consumed, such that individuals decided to drink more alcohol on days when they reported higher levels of either incentive dimension. The results also revealed that only social/party incentives interacted with impulsivity, such that highly impulsive individuals decided to drink more at events with more social/party incentives.
Findings highlight that highly impulsive individuals appear to be more responsive to social/party incentives at drinking events. Future research could benefit from continued exploration of social rewards as potential precursors to heavy drinking in highly impulsive individuals.
冲动性与过度饮酒及与酒精相关的负面后果有关。然而，此前的研究尚未采用一种体内研究方法（即每日日志）来探究冲动性对过度饮酒的影响是如何通过特定情境机制（如激励因素）来调节的。
该研究招募了一组年轻成年人样本（n = 102，61.8%为女性），他们连续两周回答关于饮酒总量以及影响其饮酒决定的激励因素（酒精激励和社交/派对激励）的问题。在基线时，参与者完成一份评估特质冲动性的问卷。
研究结果表明，社交/派对激励和酒精激励对饮酒总量有显著的主效应，即当个体报告在任何一个激励维度上处于较高水平时，他们在这些日子里会决定饮用更多的酒。结果还显示，只有社交/派对激励与冲动性存在交互作用，即高度冲动的个体在社交/派对激励更多的活动中会决定饮用更多的酒。
研究结果突出表明，高度冲动的个体在饮酒活动中似乎对社交/派对激励反应更为敏感。未来的研究可以继续探索社交奖励作为高度冲动个体大量饮酒的潜在先兆，这将从中受益。
