Speech and language profiles in 4-to 6-year-old children with early diagnosis of autism spectrum disorder without intellectual disability

Abstract

Purpose: This study aimed to present speech and language data from a community-representative group of 4-to 6-year-old children with early-diagnosed autism spectrum disorder (ASD) without intellectual disability (ID). Methods: The study group comprised 83 children 4–6 years of age with ASD without ID. They had been diagnosed with ASD before age 4.5 years and had received intervention at a specialized habilitation center. At 2-year follow-up, their language abilities were evaluated comprehensively by two speech–language pathologists using a battery of assessments. Receptive and expressive language and phonology were examined. The phonology evaluation included measures of phonological speech production and of phonological processing. Results: Results revealed that almost 60% had moderate–severe language problems. Nearly half exhibited combined expressive and receptive language problems, of which a majority also had phonology problems. Phonological speech problems were found in 21% of the total group. Conclusion: The findings underscore the importance of considering speech/language disorders in children with ASD without ID, since they usually attend mainstream classes but need specific educational adaptations.
