Short report. Narrative competence in Italian preschool children with sex chromosome trisomies.
Preschoolers with sex chromosome trisomies tell markedly weaker stories than peers—screen early and teach narrative structure.
01Research in Context
What this study did
Miller et al. (2022) compared preschool stories from kids with sex chromosome trisomies to stories from matched peers.
They used picture books and open prompts to collect short oral stories.
Trained raters scored each tale for macrostructure, microstructure, and overall coherence.
What they found
Children with trisomies told shorter, simpler stories on almost every measure.
Gaps showed up in story grammar, complex sentences, and overall cohesion.
The deficits were large enough to flag a need for early language services.
How this fits with other research
Newell et al. (2025) saw the same pattern in older Chilean kids with Down syndrome, proving narrative trouble persists across genetic disorders and cultures.
Saravanaperumal et al. (2025) found nearly identical microstructure gaps in Tamil-speaking autistic preschoolers, suggesting shared language-planning issues.
Blom et al. (2016) offers hope: they showed that attention support can shrink macrostructure gaps in kids with plain language impairment, hinting at a treatment angle for SCT.
Why it matters
If you serve preschoolers with genetic or developmental risk, add a quick story-retell probe to your intake. One picture book and five minutes can spot kids who need narrative goals before kindergarten. Target story grammar first, then weave in complex sentences and emotion words. Early work now saves reading-comprehension headaches later.

03Original abstract
BACKGROUND: The neuropsychological profile of children with sex chromosome trisomies [SCTs] is frequently characterised by delays and impairments in language development. However, no studies so far have specifically investigated their narrative competence. AIMS: The aim of the study was to analyse the oral narrative competence of preschool children with SCTs due to the importance of this skill for language development and learning abilities. METHODS AND PROCEDURES: Participants were 34 Italian children with SCTs one-to-one matched by age and sex to typically developing [TD] children. A storytelling task, the Narrative Competence Task, was used to assess the macrostructural and microstructural features of the children's narratives. OUTCOMES AND RESULTS: Children with SCTs showed significantly lower scores than TD peers in all the narrative indices considered, except for mental state lexicon and story length in words. CONCLUSIONS AND IMPLICATIONS: The problems found in narrative competence confirmed the existence of difficulties in the language development of children with SCTs. Narrative difficulties could affect these children's future learning skills and academic achievements.
