Abstract:

Objective To explore the prediction effect of communicative vocalization on expressive vocabulary in children with autism spectrum disorder (ASD).

Methods From February, 2021 to February, 2022, 40 children with ASD whose expressive vocabularies contained fewer than 20 words were recruited at East China Normal University. Communicative vocalization was assessed using a semi-structured play-based interaction at baseline. Twelve months later, expressive vocabulary was measured with the Putonghua Communicative Development Inventory.

Results Communicative canonical syllable vocalization significantly and positively predicted expressive vocabulary in children with ASD (B = 0.939, β = 0.586, t = 4.655, P < 0.001).

Conclusion Communicative canonical syllable vocalization in children with ASD may predict subsequent development in expressive vocabulary. Clinical interventions should place greater emphasis on fostering communicative canonical syllable vocalization in ASD.

Key words: autism spectrum disorder, communicative vocalization, expressive vocabulary
