Children with Attention-Deficit/Hyperactivity Disorder (ADHD) often struggle with writing composition, possibly due to deficits in executive functions and processing speed. This study examined 518 children with ADHD and 851 controls to assess these effects. Multiple mediation tested whether executive functions (i.e., working memory, inhibition) and processing speed partially mediated the association between inattention and writing composition, controlling for transcription. Results showed inattention negatively predicted writing composition. Executive function accounted for nearly 10%, and processing speed nearly 17%, of the variance in this association. Findings highlight the contributions of executive functions and processing speed to writing difficulties in ADHD.
患有注意力缺陷多动障碍（ADHD）的儿童在写作方面常常存在困难，这可能是由于执行功能和处理速度方面的缺陷所致。本研究对518名患有ADHD的儿童和851名对照组儿童进行了检查，以评估这些影响。多重中介分析检验了执行功能（即工作记忆、抑制能力）和处理速度是否在控制抄写因素的情况下，部分介导了注意力不集中与写作之间的关联。结果显示，注意力不集中对写作有负面预测作用。在这种关联中，执行功能占方差的近10%，处理速度占近17%。研究结果突出了执行功能和处理速度对ADHD儿童写作困难的影响。
