Impulsivity is now widely viewed as a multidimensional construct consisting of a number of related dimensions. Although many measures of impulsivity are correlated, most recent factor analyses support at least a two-factor model. In the current paper, these two factors have been labelled reward sensitivity, reflecting one of the primary dimensions of Gray's personality theory, and rash-spontaneous impulsiveness. The evidence supporting the existence of two dimensions of impulsivity is reviewed in relation to substance misuse and binge eating.
冲动性现在被广泛视为一个多维概念，由多个相关维度组成。尽管许多冲动性测量指标相互关联，但最近的大多数因素分析都支持至少一个双因素模型。在本文中，这两个因素被标记为奖励敏感性，反映了格雷人格理论的主要维度之一，以及鲁莽-自发冲动性。本文回顾了与物质滥用和暴饮暴食相关的支持冲动性存在两个维度的证据。
