冲动作为一种行为结构，包含了广泛的通常被认为是适应不良的行为。冲动性已被评估使用各种措施，包括自我报告的个性问卷和行为任务，这些措施中的每一个已被进一步细分为单独的组成部分，被认为是代表不同的潜在过程。然而，很少有研究同时使用人格测量和行为任务，因此这些测量之间的关系还没有得到很好的理解。在一项分析中，我们检查了三种广泛使用的人格测量（即，BIS-11，I-7和MPQ）和四个实验室任务测量冲动行为（行为抑制（2），延迟折扣，和冒险）在70名健康成年志愿者。各种自我报告的措施之间的相关性很高，但自我报告与行为任务的措施不相关。在第二个分析中，我们使用99名参与者的四个行为任务的数据进行了主成分分析。两个组件出现，标记为“冲动去抑制”（停止任务和去/不去任务）和“冲动决策”（延迟折扣任务和气球模拟风险任务）。总的来说，这些分析支持其他最近的研究结果表明，自我报告和行为任务可能测量不同的结构，并表明，即使在行为措施，不同的任务测量不同的，也许无关的，冲动行为的组成部分。(c)2005爱思唯尔有限公司保留所有权利。
Impulsivity as a behavioral construct encompasses a wide range of what are often considered maladaptive behaviors. Impulsivity has been assessed using a variety of measures, including both self-report personality questionnaires and behavioral tasks, and each of these measures has been further subdivided into separate components which are thought to represent different underlying processes. However, few studies have employed both personality measures and behavioral tasks, and so the relations among these measures are not well understood. In one analysis we examined correlations between three widely used personality measures (i.e., BIS-11, I-7, and MPQ) and four laboratory-task measures of impulsive behavior (behavioral inhibition (2), delay discounting, and risk taking) in 70 healthy adult volunteers. The correlations among the various self-report measures were high, but self-reports were not correlated with behavioral-task measures. In a second analysis we performed a principal-components analysis using data from the four behavioral tasks for 99 participants. Two components emerged, labeled "impulsive disinhibition" (Stop Task and Go/No-Go task) and "impulsive decision-making" (Delay-Discounting task and Balloon Analog Risk Task). Taken collectively, these analyses support other recent findings indicating that self-report and behavioral tasks probably measure different constructs, and suggest that even among the behavioral measures, different tasks measure different, perhaps unrelated, components of impulsive behavior.
