Sibling-Implemented Script Fading to Promote Play-Based Statements of Children with Autism.

We trained three typically developing children to implement a script-fading procedure with their younger siblings with autism. The number of contextually appropriate statements made by the children with autism increased once treatment was initiated. Participants continued to emit higher levels of contextually appropriate statements after the scripts were completely faded and at a 4- or 11-week follow-up. The typically developing siblings were able to implement the script-fading procedure with high levels of fidelity.
