Difficulties in phonological processing and reading that characterize developmental dyslexia have been suggested also to affect those with attention-deficit/hyperactivity disorder (ADHD). However, it is not known to what extent various intervening factors, such as low intelligence quotient or age, explain the observed difficulties. In this study, the authors investigated the domains of phonological processing, reading, spelling, and arithmetic in 110 adults (ages 18-55 years) in healthy control, dyslexia, and ADHD groups.The aim of the study was specifically to compare domain profiles of participants with ADHD to those in other groups.The results showed that participants with dyslexia had the most generalized difficulties. Participants with ADHD were the least affected, and their difficulties reflected less accurate performance. Furthermore, all the observed differences became nonsignificant when intelligence quotient was controlled for. This suggests that adult ADHD is not related to significant impairments in phonological processing or achievement.
发展性阅读障碍的语音处理和阅读困难被认为也会影响注意力缺陷/多动障碍（ADHD）患者。然而，目前尚不清楚各种干预因素（如智商低或年龄）在多大程度上解释了观察到的困难。在这项研究中，作者调查了 110 名健康对照组、阅读障碍组和 ADHD 组成年人（18-55 岁）的语音处理、阅读、拼写和算术领域。研究的目的是专门比较 ADHD 患者与其他组的领域特征。结果表明，阅读障碍患者的问题最普遍。ADHD 患者受影响最小，他们的困难反映了表现不够准确。此外，当控制智商时，所有观察到的差异均变得无统计学意义。这表明，成人 ADHD 与语音处理或学习成绩的显著损伤无关。
