Comprehensive Communication Intervention for Minimally Verbal Children With Autism

Overview The goal of Comprehensive Communication Intervention for Minimally Verbal Children with Autism is to conduct an efficacy study of a promising intervention to increase spoken language in preschool children who are minimally verbal. The proposed study compares a comprehensive communication intervention (JASP- EMT Plus; JEP) to a business as usual (BAU) control group in a randomized controlled trial (RCT) across 4 time points. The study replicates and extends procedures used by Kasari, Kaiser et al (2014) to successfully promote social communication in older minimally verbal children. Intervention components include: (1) Joint Attention, Structured Play, Engagement and Regulation and Enhanced Milieu Teaching (JASP- EMT), (2) applied with systematic parent training, (3) use of speech generating device (SGD) and (4) supplementary direct teaching of foundational skills for language learning as indicated by child entry skills (CORE-DTT; Smith, 2009). Children who remain minimally verbal beyond age 5 are at high risk for persistent, severe communication deficits that impact social development, educational achievement and quality of life (Tager-Flusberg \& Kasari, 2013). Thus, there is an urgent need for effective strategies to promote communication development during the preschool years to ameliorate early communication deficits and prevent persistent minimally verbal status. This study aims to change social communication in minimally verbal preschool children with ASD by applying a naturalistic social communication intervention which teaches the social foundations of communication and functional use of verbal language in play and interaction. In addition, the intervention addresses three factors that may contribute to remaining minimally verbal: lack of an effective mode of speech production, lack of foundational skills for learning language (receptive language, imitation, joint attention), and lack of communication partners to support continued language learning
