Handwriting is commonly identified as an area of weakness in children with autism spectrum disorder (ASD), but precise deficits have not been fully characterised. Boys with ASD (n = 23) and matched controls (n = 20) aged 8-12 years completed a simple, digitised task to objectively assess handwriting performance using advanced descriptive measures. Moderate to large associations were identified between handwriting performance and attention, ASD symptoms and motor proficiency. The ASD group demonstrated significantly less smooth movements and significantly greater sizing variability and peak velocity relative to controls. These findings provide a clearer indication of the specific nature of handwriting impairments in children with ASD, and suggest a relationship with core clinical symptom severity, attention and motor behaviours.
书写通常被认为是自闭症谱系障碍（ASD）儿童的一个弱点领域，但具体的缺陷尚未得到充分描述。8至12岁的ASD男孩（n = 23）和匹配的对照组（n = 20）完成了一项简单的数字化任务，以使用先进的描述性测量方法客观评估书写表现。研究发现书写表现与注意力、ASD症状和运动熟练度之间存在中度到高度的关联。与对照组相比，ASD组的动作明显更不流畅，尺寸变化和峰值速度明显更大。这些发现更清楚地表明了ASD儿童书写障碍的具体性质，并表明与核心临床症状严重程度、注意力和运动行为之间存在关联。
