Morphosyntactic profiles among preschoolers with and without speech sound disorders

The aim of the current study was to identify whether certain morphosyntactic constructs are more difficult for children with speech sound disorder than children with typical speech development. In this post-hoc study, we used chi-square analyses to identify group differences on individual questions on a standardised test of expressive morphosyntax. Participants included 80 preschool-age children, 40 with typical speech and language development (TD), and 40 with speech sound disorder and typical language development (SSD). A chi-square analysis revealed group (TD vs. SSD) differences in usage of subject pronouns, irregular past tense verbs, and yes/no interrogative formation. Ordinal logistic regression revealed that phonological awareness was related to irregular past tense verb use. Children with SSD may present with subclinical morphosyntax difficulties. Speech-language pathologists should consider incorporating morphosyntax assessment into test batteries for children with SSD.

Automated summary

This study aimed to investigate differences in morphosyntactic abilities between children with speech sound disorder and typically developing children. The results showed that children with speech sound disorder had difficulties in using subject pronouns, irregular past tense verbs, and forming yes/no interrogative sentences. Furthermore, it was found that phonological awareness was related to the use of irregular past tense verbs.
