危险饮酒既与冲动增加有关，也与酒精相关线索引发的自动接近倾向有关。然而，冲动是一个多因素的结构，目前还不清楚冲动的所有组成部分是否都与酗酒有关。此外，新出现的证据表明，危险饮酒和自动酒精认知之间的关系可能会受到个人冲动差异的调节。本研究的目的是调查冲动测量方法的独立性及其与危险饮酒的关联，并检查危险饮酒和自动饮酒倾向之间的关系是否会受到个人冲动差异的调节。97名社交饮酒者(65名女性)完成了关于特质冲动、饮酒和危险饮酒的问卷测量。参与者还完成了自动饮酒倾向的计算机化测量(刺激-反应兼容性(SRC)任务)，以及两种行为冲动测量(去/不去和延迟打折任务)。主成分分析显示，这两种行为冲动测量彼此不同，与自我报告的特质冲动不同，尽管自我报告的非计划性冲动与两个因素(特质冲动和延迟打折)有关。此外，所有测量冲动的指标都预测了危险饮酒的独特差异，自动饮酒倾向也是如此，尽管后一种关系不受冲动的调节。这些结果表明，冲动和自动饮酒倾向的多个组成部分解释了危险饮酒的独特差异。
Hazardous drinking is associated with both increased impulsivity and automatic approach tendencies elicited by alcohol-related cues. However, impulsivity is a multi-factorial construct, and it is currently unclear if all components of impulsivity are associated with heavy drinking. Furthermore, emerging evidence suggests that the relationships between hazardous drinking and automatic alcohol cognitions may be moderated by individual differences in impulsivity.The aim of this study was to investigate the independence of measures of impulsivity and their association with hazardous drinking, and to examine if the relationship between hazardous drinking and automatic alcohol approach tendencies would be moderated by individual differences in impulsivity.Ninety-seven social drinkers (65 female) completed questionnaire measures of trait impulsivity, alcohol consumption and hazardous drinking. Participants also completed computerised measures of automatic alcohol approach tendencies (stimulus-response compatibility (SRC) task), and two behavioural measures of impulsivity (Go/No-go and delay discounting tasks).Principal component analysis revealed that the two measures of behavioural impulsivity were distinct from each other and from self-reported trait impulsivity, although self-reported non-planning impulsivity loaded on to two factors (trait impulsivity and delay discounting). Furthermore, all measures of impulsivity predicted unique variance in hazardous drinking as did automatic alcohol approach tendencies, although the latter relationship was not moderated by impulsivity.These results indicate that multiple components of impulsivity and automatic alcohol approach tendencies explain unique variance in hazardous drinking.
