Pivotal Response Group Treatment for Parents of Young Children With Autism

This is a research study examining the effectiveness of pivotal response treatment group (PRTG) in targeting language skills in young children with autism. Research has demonstrated that behavioral interventions, such as Pivotal Response Training (PRT), lead to improvements in the core symptoms of autism. The purpose of this study is to further examine the effectiveness of teaching pivotal response treatment to parents of children with autism in a group format. To determine the effectiveness of pivotal response training group (PRTG) it will be compared to another parent education group by conducting a randomized controlled 12-week trial.
