研究人员已经明确指出，冲动在物质使用障碍中起着关键作用，自我报告测量的比较表明，冲动行为有明显不同的组成部分。然而，相对较少的研究致力于利用实验室的冲动测量来理解这一结构的多维性质，这些测量可能对跟踪随时间的变化更为敏感。许多研究测量了冲动性，但这一结构是使用通常孤立使用的不同类型的实验室冲动性范例在方法论上测量的。因此，重要的是要确定一些最常用的冲动行为测量类型是否解释了独特的差异。在这里，我们在两项研究中使用了因子分析技术来评估三种最常用的行为冲动范式的独立性。首先，使用以前收集的数据进行因子分析(n=204)，其次，专门收集数据以复制和扩展我们最初分析的结果(n=198)。这两项研究都揭示了三个不同的因素，证实了我们的假设，即至少有三个冲动行为成分可以通过这些方法论方法来衡量。这些发现表明，研究人员应该仔细考虑他们对实验室行为冲动指标的选择，所选的指标(S)应该与物质使用障碍和治疗成功相关的特定潜在过程有关。
Researchers have clearly implicated impulsivity as having a key role in substance use disorders, and comparisons of self-report measures suggest there are measurably different components of impulsive behavior. However comparatively little research has been devoted to understanding the multidimensional nature of this construct using laboratory measures of impulsivity that may be more sensitive to tracking changes across time. Many studies have measured impulsivity, but this construct has been measured using methodologically different types of laboratory impulsivity paradigms that are often used in isolation. As a result, it is important to determine whether some of the most frequently used types of behavioral measures of impulsivity account for unique variance. Here, we used factor analytical techniques in two studies to evaluate the independence of three of the most commonly used behavioral impulsivity paradigms. First, a factor analysis was conducted using previously collected data (n = 204), and second, data was gathered specifically to replicate and extend the results of our original analysis (n = 198). Both studies revealed three distinct factors, confirming our hypothesis of at least three components of impulsive behavior that can be measured by these methodological approaches. These findings suggest that researchers should carefully consider their selection of laboratory-behavioral impulsivity measures, and that the measure(s) selected should be related to the particular underlying processes relevant to substance use disorders and treatment success.
