Current profiles and early predictors of reading skills in school-age children with autism spectrum disorders: A longitudinal, retrospective population study

The ‘poor readers’ scored low on all assessments, as well as showing more severe autistic behaviours than ‘skilled readers’. Group differences between ‘skilled readers’ and ‘hyperlexics/poor comprehenders’ were more subtle: these subgroups did not differ on autistic severity, phonological processing or non-verbal intelligence quotient, but the ‘hyperlexics/poor comprehenders’ scored significantly lower on tests of oral language.

When data from age 3 were considered, no differences were seen between the subgroups in social skills, autistic severity or intelligence quotient. Importantly, however, it was possible to identify oral language weaknesses in those that 5 years later presented as ‘poor readers’ or ‘hyperlexics’.
