School-entry language skills as predictors of concurrent and future academic, social, and adaptive skills in kindergarteners with ASD.

Abstract

OBJECTIVE\nThis study compared language profiles of children with autism spectrum disorder (ASD) and typically developing (TD) children at kindergarten-entry and investigated whether kindergarten-entry language scores were predictive of concurrent and future academic achievement, peer interactions, and adaptive skills in children with ASD.\n\n\nMETHOD\nParticipants included 97 children (62 children with ASD; 35 TD children) assessed at kindergarten-entry and -exit. Language abilities were assessed using the Children s Communication Checklist-2 (CCC-2). Children with ASD and TD children s language scores were compared at baseline, and the ASD group was followed longitudinally. Regression analyses were performed to compare language scores between ASD and TD groups and to predict concurrent and future functional skills from kindergarten-entry language scores for children with ASD.\n\n\nRESULTS\nChildren with ASD demonstrated significantly more impairments across all scales of the CCC-2 at kindergarten-entry compared to TD children. Within the ASD group, kindergarten-entry pragmatic language significantly predicted concurrent math and reading achievement. Both syntactic/semanticand pragmatic domains significantly predicted kindergarten-exit reading performance; pragmatics significantly predicted kindergarten-exitmath performance. Pragmatics also predicted concurrent and kindergarten-exit peer play. Syntax/semantics significantly predicted concurrent adaptive communication skills, whereas pragmatics significantly predicted concurrent adaptive daily living and socialization skills, as well as kindergarten-exit socialization skills.\n\n\nCONCLUSIONS\nSchool-entry language abilities can serve as a valuable predictor of functional outcomes across the kindergarten year for cognitively-able children with ASD. Results highlight the need to target early language abilities to maximize academic, social, and adaptive skills.
