冲动和冒险是涉及大量饮酒和酒精问题的多维结构。我们的目的是确定冲动或冒险的具体组成部分，解释了从大学人群中招募的年轻人样本中大量饮酒和问题饮酒的最大差异。参与者（N = 75）完成了一个测试电池，包括两个常用的反应抑制任务（去/不去任务和停止信号任务），延迟折扣程序，和气球锚定风险任务（BART）作为衡量风险承担。参与者还完成了Barratt冲动量表（BIS）作为特质冲动的衡量标准。在分层多元回归模型中，冒险被确定为预测酒精使用和问题的唯一行为措施。在二次分析中，我们证明了冒险行为预测了酒精使用和问题的独特差异，这些差异超过了特质冲动性的解释。结果表明，在年轻人中，冒险行为的测量预测变量的酒精消费和酒精问题，即使在特质冲动的个体差异进行统计控制。然而，行为措施的反应抑制和延迟折扣不预测独特的变化，在年轻的成年人饮酒的社会。(C)2010爱思唯尔爱尔兰有限公司版权所有。
Impulsivity and risk-taking are multi-dimensional constructs that have been implicated in heavy drinking and alcohol problems. Our aim was to identify the specific component of impulsivity or risk-taking that explained the greatest variance in heavy and problem drinking among a sample of young adults recruited from a university population. Participants (N = 75) completed a test battery comprising two commonly used response inhibition tasks (a Go/No-Go task and a Stop signal task), a delay discounting procedure, and the Balloon Analogue Risk Task (BART) as a measure of risk-taking. Participants also completed the Barratt Impulsivity Scales (BIS) as a measure of trait impulsivity. In a hierarchical multiple regression model, risk-taking was identified as the only behavioural measure that predicted alcohol use and problems. In a secondary analysis, we demonstrated that risk-taking predicted unique variance in alcohol use and problems over and above that explained by trait impulsivity. Results suggest that among young adults, a behavioural measure of risk-taking predicts variance in alcohol consumption and alcohol problems, even when individual differences in trait impulsivity are statistically controlled. However, behavioural measures of response inhibition and delay discounting do not predict unique variance in alcohol use in young adult social drinkers. (C) 2010 Elsevier Ireland Ltd.
