关于注意力缺陷多动障碍（ADHD）的维度与分类性质存在争议。本研究利用验证性因素分析来探讨这一问题。对来自患有ADHD的个体（年龄3-17岁，74%男性，75%高加索人）的大样本（n= 242）的在访谈和评定量表上评定的ADHD症状进行了检查。四个潜在的因素结构进行了测试，以复制以前的研究结果，在一个样本与广泛的年龄范围，并包括只有参与者谁满足DSM-IV-TR诊断标准的ADHD。与执行功能的措施进行相关性，以进一步评估分离性和有效性的衍生因素。这些数据支持一个双因素模型，其中包括一个一般的ADHD因素和两个特定的因素，注意力不集中和多动/冲动。重要的是，个别因素也与执行功能的措施差异相关。这项研究增加了越来越多的文献，表明ADHD的一般组成部分，以及注意力不集中和多动/冲动的维度特征，与不同的执行功能配置文件相关。一般潜在因素的存在禁忌将注意力不集中和ADHD的组合亚型分为不同的疾病。
There is debate regarding the dimensional versus categorical nature of attention-deficit/hyperactivity disorder (ADHD). This study utilized confirmatory factor analysis to examine this issue. ADHD symptoms rated on interviews and rating scales from a large sample of individuals (ages 3–17, 74 % male, 75 % Caucasian) with ADHD were examined (n= 242). Four potential factor structures were tested to replicate prior findings in a sample with a wide age range and included only participants who metDSM-IV-TRdiagnostic criteria for ADHD. Correlations with executive function measures were performed to further assess the separability and validity of the derived factors. The data support a bifactor model with a general ADHD factor and two specific factors, inattention and hyperactivity/impulsivity. Importantly, the individual factors were also differentially correlated with executive functioning measures. This study adds to a growing literature suggesting both a general component to ADHD, as well as dimensional traits of inattention and hyperactivity/impulsivity, associated with distinct executive functioning profiles. The presence of a general underlying factor contraindicates separating the inattentive and combined subtypes of ADHD into distinct disorders.
