Studies examining narrative production skills in children with autism spectrum disorder (ASD) have demonstrated variable and inconsistent results. This study aimed to investigate to what extent narrative difficulties in children with ASD reflect difficulties with language.
Accordingly, the spoken narrative skills of 16 children with ASD were compared with those of their 16 chronological age-matched (CAM) and 16 language-matched (LM) peers. A Kruskal-Wallis non-parametric test was then used to examine the differences between groups in regard to NTC, NSG and SI variables .For other studied variables (NTW, number of T-units, ATL and total score), one-way analysis of variances (ANOVA) was also used.
At the level of microstructure, the results showed that productivity (number of total words, total clauses, and T-unites) and syntactic complexity (average of T-unit length and subordination index) were predominantly similar in ASD and LM children. However, children with ASD scored lower than their CAM counterparts ( < 0.001). At the macrostructure level, we found that the total score of story grammar elements and the number of story grammars in the narrative production of children with ASD were lower than those in both CAM and LM children ( < 0.001).
The present study, thus, showed that creating a coherent narrative could be more demanding for children with ASD than productivity and syntactic complexity.
研究自闭症谱系障碍（ASD）儿童的叙事能力，结果显示存在变化且不一致。本研究旨在调查ASD儿童的叙事困难在多大程度上反映了语言困难。
因此，将16名ASD儿童的口语叙事技能与其16名年龄匹配（CAM）和16名语言匹配（LM）的同龄人进行比较。然后使用Kruskal-Wallis非参数检验来检查组间在NTC、NSG和SI变量方面的差异。对于其他研究变量（NTW、T单位数量、ATL和总分），也使用了单因素方差分析（ANOVA）。
在微观结构层面，结果显示ASD儿童和LM儿童在生产力（总单词数、从句总数和T单位）和句法复杂性（T单位长度平均值和从属指数）方面基本相似。然而，ASD儿童的得分低于年龄匹配的同龄人（<0.001）。在宏观结构层面，我们发现ASD儿童叙事中故事语法元素的总分和故事语法数量低于CAM儿童和LM儿童（<0.001）。
因此，本研究表明，对于ASD儿童来说，构建连贯的叙事可能比提高生产力和句法复杂性要求更高。
