Topic: Language Regression as a Predictor of Outcomes in Children with ASD Through the Preschool Years
Many parents of young children with autism spectrum disorder (ASD) report a loss of previously attained developmental skills – a phenomenon known as regression. One particularly salient skill domain in which these early losses occur is communication. But does a history of early communication regression have an impact on children’s later language outcomes? In order to answer this question, a sample of 129 children with ASD was followed throughout the preschool years. Children were grouped according to their history of regression using three progressively less strict criteria. Results indicated poorer receptive language and a larger discrepancy between receptive and expressive language in the regression group at 44 months but not 66 months, and among those with regression, number of words used before loss was predictive of receptive language at 44 months. Study results overall suggest a subtle and transient effect on language outcomes associated with a regression profile in ASD that is no longer detectable by the time of school entry.
