School-Age Children With Autism With Limited Expressive Language Skills

This project will address a major challenge to the field of autism research: improving expressive communication in children with autism who have reached school age but have not acquired functional spoken language (non-verbal school aged children with autism; NVSACA). Fifteen children who completed the RO1 ICAN intervention (NCT01018407) at the Kennedy Krieger site and follow-up testing but continue to have minimal functional spoken language will be participants in this study. After eligibility is established, participants will be randomly assigned to a baseline duration of one week, two weeks or three weeks before the start of active treatment. Once the baseline duration is completed, participants begin active treatment one hour of intervention three days per week in the participants' school setting. In month 2, weekly teacher trainings begin. In month 5, weekly parent trainings begin to improve the child's generalization of skills and teach parents the strategies implemented in their child's treatment. Post-baseline and post-treatment assessments will be completed in the lab at a time that is convenient for the participants' families.
