Current diagnostic criteria specify that ADHD involves difficulties with inattention and/or hyperactivity/impulsivity. Researchers using factor analysis have consistently found support for an inattention factor in both children and adults. Findings have been mixed regarding whether hyperactivity and impulsivity reflect one or two dimensions. To date, no study has examined the merits of separating hyperactivity and impulsivity factors to predict socioemotional and academic outcomes in young adults.
The current study examined self-reported ADHD symptomatology data from 1,096 college students. Subsets of the sample completed a variety of outcome measures.
The prediction of outcomes provided support that complemented confirmatory factor analysis for the separation of the hyperactivity and impulsivity constructs. Impulsivity uniquely predicted more outcomes than hyperactivity alone.
Results were consistent with the conceptualization of ADHD as primarily a disorder of behavioral inhibition. Future research using alternative outcomes and clinical populations should be conducted.
目前的诊断标准规定，注意力缺陷多动障碍（ADHD）涉及注意力不集中和/或多动/冲动问题。使用因子分析的研究人员在儿童和成人中均一致发现对注意力缺陷因子的支持。关于多动和冲动是否反映一个或两个维度的发现结果不一。迄今为止，尚无研究探讨将多动和冲动因素分开以预测青年成年人的社会情感和学业结果的优点。
本研究从 1096 名大学生中检查了自我报告的 ADHD 症状数据。样本的子集完成了各种结果测量。
对结果的预测提供了支持，这对多动和冲动结构分离的验证性因子分析提供了补充。冲动性比单纯的多动性更能预测更多的结果。
结果与将 ADHD 主要概念化为行为抑制障碍的概念一致。应进行使用替代结果和临床人群的未来研究。
