Developmental coordination disorder (DCD) is a neurodevelopmental disorder characterized by deficits in performing motor tasks. Research suggests social skills are also altered. To investigate (1) whether the presence of DCD affects social responsiveness, (2) whether the co-occurrence of autism spectrum disorder (ASD) affects social responsiveness in children with DCD, and (3) whether there is an association between motor performance and social responsiveness in children with DCD. Based on parental reports, children aged 5 to 15.5 years were assigned to one of three groups: DCD only (noASD, = 67), DCD and suspected ASD (sASD, = 13), and DCD and confirmed ASD (cASD, = 22). Parental answers to the Social Responsiveness Scale (SRS-2) and the DCD-Questionnaire (DCD-Q) were compared to norm values using one sample -tests, and between groups using ANOVA and MANOVA. Pearson correlation coefficients explored the relationship between the SRS-2 and DCD-Q in the total group and per group. Compared to norm values, difficulties in all areas of social responsiveness were reported in children with DCD, regardless of group (<0.001). Compared to the noASD group, more unfavorable SRS-2 total T-scores and poorer DCD-Q scores were observed in sASD and cASD groups. Only in the total group, motor performance showed significant weak to moderate associations with the SRS-2 total T-score and all subscales except for ‘social motivation’ (=-0.306 to -0.405; ≤ 0.02). Social responsiveness difficulties are more common in children with DCD and are more severe in the ASD groups. Motor performance and social responsiveness are weak to moderately associated.

发育协调障碍儿童的社会反应能力

发育协调障碍（DCD）是一种神经发育障碍，其特征是执行运动任务时出现缺陷。研究表明社交技能也会改变。旨在调查 (1) DCD 的存在是否影响社会反应能力，(2) 自闭症谱系障碍 (ASD) 的同时出现是否影响 DCD 儿童的社会反应能力，以及 (3) 运动表现与社交反应之间是否存在关联。 DCD 儿童的社会反应能力。根据家长报告，5 至 15.5 岁的儿童被分配到三组之一：仅 DCD（无 ASD，= 67）、DCD 和疑似 ASD（sASD，= 13）以及 DCD 和确诊 ASD（cASD，= 22） 。使用单样本测试将父母对社会反应量表 (SRS-2) 和 DCD 问卷 (DCD-Q) 的回答与正常值进行比较，并使用方差分析和多元方差分析在各组之间进行比较。Pearson 相关系数探讨了总组和每组中 SRS-2 和 DCD-Q 之间的关系。与正常值相比，患有 DCD 的儿童在所有社会反应能力方面都存在困难，无论哪个组（<0.001）。与 noASD 组相比，sASD 和 cASD 组观察到更不利的 SRS-2 总 T 分数和较差的 DCD-Q 分数。仅在整个组中，运动表现与 SRS-2 总 T 分数和除“社交动机”之外的所有分量表（=-0.306 至 -0.405；≤ 0.02）表现出显着的弱至中度关联。社交反应困难在患有发展性协调障碍 (DCD) 的儿童中更为常见，并且在自闭症谱系障碍 (ASD) 群体中更为严重。运动表现和社交反应能力弱到中度相关。NCT05092893 ()
