Questions remain as to whether neuropsychological processing deficits associated with child attention-deficit/hyperactivity disorder (ADHD) are accounted for by co-occurring disorders, especially in clinical samples. The authors examined ADHD and comorbid oppositional defiant, conduct, and reading disorders. Boys with ADHD displayed hypothesized deficits on effortful neuropsychological tasks regardless of categorical or dimensional control of comorbid antisocial behavior problems. The same result held when reading problems were controlled, although boys with ADHD plus reading disorder (n = 16) exhibited specific impairment on linguistic output tasks. Simultaneous control of reading and behavior problems yielded the same result. Overall, results suggest that in a clinical sample, difficulties on effortful neuropsychological tasks that require planning or controlled motor output pertain at least in part to ADHD and are not fully accounted for by comorbid conditions.
与儿童注意力缺陷多动障碍（ADHD）相关的神经心理加工缺陷是否由共病引起，尤其是在临床样本中，这一问题仍有待解答。作者研究了ADHD与对立违抗、品行和阅读障碍的共病情况。患有ADHD的男孩在需要努力的神经心理任务上表现出假设的缺陷，无论对共病的反社会行为问题进行分类还是维度控制都是如此。在控制了阅读问题后，结果依然相同，尽管患有ADHD加阅读障碍的男孩（n = 16）在语言输出任务上表现出特定的损伤。同时控制阅读和行为问题也得到了相同的结果。总体而言，结果表明，在临床样本中，需要计划或控制运动输出的努力神经心理任务上的困难至少部分与ADHD有关，并且不能完全由共病情况来解释。
