冲动是一个多方面的结构，它定义了一系列适应不良的行为风格。本研究旨在通过一系列实验室行为评估来确定青少年冲动行为的不同维度。在一项分析中，研究人员检查了两份自我报告和七项冲动性的实验室行为测量之间的相关性。与自我报告和实验室行为测量之间的相关性相比，两种自我报告测量之间的相关性较高。在第二次分析中，主成分分析仅使用实验室行为测量进行。确定了三个行为维度——“冲动性决策”、“冲动性注意力不集中”和“冲动性去抑制”。这些维度是进一步评估使用相同的样本与验证性因素分析，这确实支持假设，这些是冲动性的重要和独立的维度。这项研究表明，当对青少年参与者进行实验室行为评估时，至少有三种不同的冲动行为亚型。
Impulsivity is a multifaceted construct that defines a range of maladaptive behavioral styles. The present research aimed to identify different dimensions of impulsive behavior in adolescents from a battery of laboratory behavioral assessments. In one analysis, correlations were examined between two self report and seven laboratory behavioral measures of impulsivity. The correlation between the two self report measures was high compared to correlations between the self report and laboratory behavioral measures. In a second analysis, a principal components analysis was performed with just the laboratory behavioral measures. Three behavioral dimensions were identified-"impulsive deci sion-making", "impulsive inattention", and "impulsive disinhibition". These dimensions were further evaluated using the same sample with a confirmatory factor analysis, which did support the hypothesis that these are significant and independent dimensions of impulsivity. This research indicates there are at least three separate subtypes of impulsive behavior when using laboratory behavioral assessments with adolescent participants.
