A modified intensive behavioral therapy (IBI) program has been very helpful for children with autism in a Toronto preschool system.
The Lovaas method of applied behavior analysis (ABA) therapy has been used since the early 1980s to help improve behaviors in children with autism. The Toronto Partnership for Autism Services made some changes to the Lovaas method in their preschool autism treatment program. The Toronto IBI uses discrete trial training to teach language skills. The Toronto IBI therapy also uses the picture exchange communication system (PECS) and teaching schedules. The authors talk about the research related to Lovaas method, IBI, PECS, and teaching schedules. They also describe some practical details about how their therapy program works with children.
