Assessing Language Skills in Children Aged 4 to 6 Years with Autism Spectrum Disorder: A Prospective Study

Area of Science:

• Pediatric Psychology
• Developmental Neuroscience
• Speech-Language Pathology

Background:

• Language impairments are common in children with Autism Spectrum Disorder (ASD), impacting future social development.
• Preschool language skills are critical predictors of social outcomes in children aged 3-6 years.
• Limited research exists on using standardized language tests for preschoolers with ASD.

Purpose of the Study:

• To comprehensively assess receptive/expressive lexicon, comprehension, phonology, and articulation in preschoolers with ASD using standardized tools.
• To evaluate the feasibility of these standardized language assessments in this population.
• To compare standardized test results with developmental batteries and caregiver reports.

Main Methods:

• Forty-seven children with ASD (aged 4-6 years) underwent standardized language tests, developmental batteries, and caregiver reports.
• The dichotomous Rasch model assessed the feasibility and performance of standardized tests.
• Pearson correlations and stepwise linear regression analyzed concordance across assessment methods.

Main Results:

• Standardized language assessments were feasible for most preschoolers with ASD, despite a wide range of abilities.
• Partial, non-equivalent concordance was observed between different assessment methods.
• Each method provided unique, complementary information about language profiles.

Conclusions:

• A multimodal approach combining standardized tests, developmental batteries, and caregiver reports is essential for understanding language complexity in children with ASD.
• Adapted standardized tests offer more precise language profiles than other methods alone.
• This comprehensive strategy aids in identifying specific language strengths and therapeutic targets for preschoolers with ASD.
