This study tests a handwriting model for children and youth with Autism Spectrum Disorder (ASD) that displays the relationships between handwriting process and product characteristics, and the predictors of these characteristics. Structural Equation Modelling was used to test the model for children and youth with ASD (n = 50) and typically developing peers (n = 50), ages 10 to 15, for a copying and freestyle handwriting task. Findings suggest a generic handwriting model applying to both groups and both handwriting tasks. Unique effects for children and youth with ASD were identified for: (1) high interdependence of handwriting process characteristics, (2) longer pen stroke in air leading to better legibility, and (3) lower scores for executive functions leading to lower scores for legibility.
本研究测试了一个针对自闭症谱系障碍（ASD）儿童和青少年的手写模型，该模型展示了手写过程和产品特征之间的关系，以及这些特征的预测因素。结构方程模型用于测试 ASD 儿童和青少年（n=50）和典型发育同龄人（n=50）的模型，年龄在 10 至 15 岁之间，用于复制和自由书写任务。研究结果表明，该模型适用于两组和两种手写任务。针对 ASD 儿童和青少年，发现了一些独特的影响因素：（1）手写过程特征的高度相互依赖性，（2）在空中的笔锋更长导致更好的清晰度，以及（3）执行功能得分较低导致清晰度得分较低。
