背景青春期是大脑发育的关键时期，神经发育模型将其定位于额叶、皮质下边缘系统和纹状体的激活，这是一种与冲动性和抑制性控制缺陷相关的模式。本研究采用结构方程模型，探讨青少年冲动性和抑制性控制的自我报告与执行功能的关系。法对434名高中生进行了测试。不经思考的行为通过Barratt冲动量表和Dickman冲动量表进行测量，通过行为激活系统测量奖励敏感度，通过Zuckerman-Kuhlman-Pastija人格问卷测量感觉寻求。通过行为抑制系统评估抑制控制。在威斯康星州卡片分类任务中的表现表明了执行功能。使用样本协方差矩阵指定三个模型，并使用最大似然法估计参数。结果在最终的模型中，冲动和抑制控制预测执行功能，但感觉寻求没有。模型与数据的拟合非常好。结论.抑制性控制和冲动性是执行功能的预测因子。我们的研究结果显示，自我报告措施的有效性，以检查冲动性状之间的关系，而不是其他的认知和行为的调节功能。
Background. Adolescence represents a critical period for brain development, addressed by neurodevelopmental models to frontal, subcortical-limbic, and striatal activation, a pattern associated with rise of impulsivity and deficits in inhibitory control. The present study aimed at studying the association between self-report measures of impulsivity and inhibitory control with executive function in adolescents, employing structural equation modeling. Method. Tests were administered to 434 high school students. Acting without thinking was measured through the Barratt Impulsiveness Scale and the Dickman Impulsivity Inventory, reward sensitivity through the Behavioral Activation System, and sensation seeking through the Zuckerman-Kuhlman-Aluja Personality Questionnaire. Inhibitory control was assessed through the Behavioral Inhibition System. The performance at the Wisconsin Card Sorting Task indicated executive function. Three models were specified using Sample Covariance Matrix, and the estimated parameters using Maximum Likelihood. Results. In the final model, impulsivity and inhibitory control predicted executive function, but sensation seeking did not. The fit of the model to data was excellent. Conclusions. The hypothesis that inhibitory control and impulsivity are predictors of executive function was supported. Our results appear informative of the validity of self-report measures to examine the relation between impulsivity traits rather than others to regulatory function of cognition and behavior.
