目的：反应时间受试者内变异性（RT-ISV）升高是ADHD的特征。由儿童行为检查表焦虑/抑郁、攻击性和注意力分量表得分总和定义的情绪自我调节缺陷（DESR）与ADHD的不良结局相关。为了确定DESR是否与RT-ISV升高有差异，我们检查了伴有和不伴有DESR的ADHD儿童以及典型发育儿童（TDC）的RT-ISV。方法：我们在6分钟Eriksen Flanker任务中对比了31名ADHD儿童（无DESR）、34名ADHD儿童（有DESR）和65名TDC儿童的RT-ISV。结果：不考虑DESR，ADHD儿童的RT-ISV显著大于TDC（p < .001）。ADHD的亚组，定义为存在或不存在DESR，彼此之间没有差异。结论：增加的RT-ISV是ADHD的特征，与共病DESR无关。除了在ADHD儿童和成人中的类似发现外，这些结果表明RT-ISV与ADHD的认知而不是情绪失调有关。
Objective: Elevated response time intrasubject variability (RT-ISV) characterizes ADHD. Deficient emotional self-regulation (DESR), defined by summating Child Behavior Checklist Anxious/Depressed, Aggressive, and Attention subscale scores, has been associated with worse outcome in ADHD. To determine if DESR is differentially associated with elevated RT-ISV, we examined RT-ISV in children with ADHD with and without DESR and in typically developing children (TDC). Method: We contrasted RT-ISV during a 6-min Eriksen Flanker Task in 31 children with ADHD without DESR, 34 with ADHD with DESR, and 65 TDC. Results: Regardless of DESR, children with ADHD showed significantly greater RT-ISV than TDC (p < .001). The ADHD subgroups, defined by presence or absence of DESR, did not differ from each other. Conclusion: Increased RT-ISV characterizes ADHD regardless of comorbid DESR. Alongside similar findings in children and adults with ADHD, these results suggest that RT-ISV is related to cognitive rather than emotional dysregulation in ADHD.
