Purpose Autism spectrum disorders (ASD) are characterized by early impairments in language and related social communication skills. This investigation explored whether scores on the MacArthur–Bates Communicative Development Inventory (CDI) at ages 2 and 3 years predict outcome at age 9 years in children with ASD and developmental delay (DD).

Method Sixty-two children referred for possible autism at age 2 years, and 19 children with DD, were followed to age 9 years. Vocabulary, prespeech, and gestures scores on CDIs administered at ages 2 and 3 years were used to predict follow-up IQ, language, adaptive skills, and scores on diagnostic measures.

Results CDI scores at ages 2 and 3 did not predict outcome for the DD group. For the ASD sample, CDI receptive and expressive language and late gestures at ages 2 and 3 years predicted a number of follow-up variables, although scores at age 3 years were generally more predictive than scores at age 2 years.

Conclusions The CDI yielded scores that were predictive of outcome, suggesting that this parent report measure may be a quick and informative assessment of early verbal and nonverbal skills in children with ASD.
