The association of imperative and declarative intentional communication with language in young children with autism spectrum disorder: A meta-analysis

摘要

Background: Theoretically, specific pragmatic functions of intentional communication are differentially associated with language use in children with autism spectrum disorder (ASD). The primary purpose of this meta-analysis was to compare the relation of declarative and imperative intentional communication acts (ICAs), respectively, with language skills. We also examined five possible moderators of the separate associations and the difference in associations: metric used to quantify ICAs, expressive versus receptive language, longitudinal or concurrent correlations, within-study interobserver reliability of rating pragmatic function of ICAs, and risk for correlated measurement error.
