Brief summary
This is a research study examining the effectiveness of a Developmental Reciprocity Treatment Program (DRT-P) in treating social deficits in children with Autism Spectrum Disorders (ASD). Developmental Reciprocity Treatment is an early intervention that applies developmentally-informed teaching methods in naturalistic settings in order to target social and communication deficits. Researchers have begun to develop strategies to investigate the effectiveness of combining a parent training program teaching parents how to implement DRP with in-home, therapist-implemented treatment. To determine the effectiveness of the DRT-P, it will be compared to a delayed treatment group (DTG) by conducting a randomized controlled 24-week trial. This research will allow us to help in the development of therapeutic approaches that can meet the increasing service demands for families. We hope that investigating interventions that aim to improve core deficits will aid in providing better care for children with autism.
