Attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) often co-occur. Factor analyses of ASD traits in children with and without ASD indicate the presence of social and restrictive-repetitive behaviour (RRB) factors. This study used exploratory factor analyses to determine the structure of ASD traits (assessed using the Social Communication Questionnaire) in children with ADHD. Distinct factors were observed for 'social' and 'rigidity' traits, corresponding to previous factor analyses in clinical ASD and population samples. This indicates that the split between social-communicative and RRB dimensions is unaffected by ADHD in children. Moreover, the study also finds that there is some overlap across hyperactive-impulsive symptoms and RRB traits in children with ADHD, which merits further investigation.
注意缺陷多动障碍（ADHD）与自闭症谱系障碍（ASD）常常同时出现。对患有和未患有ASD的儿童的ASD特征进行因素分析表明，存在社交和限制性重复行为（RRB）因素。本研究采用探索性因素分析来确定患有ADHD的儿童的ASD特征结构（使用社交沟通问卷进行评估）。观察到“社交”和“刻板性”特征的不同因素，这与先前在临床ASD和人群样本中的因素分析结果一致。这表明社交沟通和RRB维度之间的划分不受儿童ADHD的影响。此外，该研究还发现，患有ADHD的儿童的多动冲动症状与RRB特征之间存在一些重叠，这值得进一步研究。
