Evaluation of a Self-Instructional Manual for Conducting Discrete-Trials Teaching with Children with Autism, Summarized Oct 26, 2010

A newly revised training manual may be helpful to teach college students and parents to use applied behavior analysis (ABA) to help children with autism.

ABA is seen by many to be the treatment of choice for children with autism. There is a large need for research-based, low-cost, rapid training to train tutors and parents to conduct discrete trial training with children with autism. This study was designed to see if a revised version of the training book used to teach students to do this type of ABA therapy was useful.

The Use of Intensive Behavioural Intervention for Children with Autism, Summarized Nov 2, 2009

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.

Efficacy of Applied Behavioral Intervention in Preschool Children with Autism for Improving Cognitive, Language, and Adaptive Behavior: A Systematic Review and Meta-Analysis, Summarized Jun 24, 2009

Applied behavioral analysis (ABA) therapies may not be better than standard care in special education for children with autism. The authors looked at 13 research studies on the effectiveness of ABA intervention. These were well run studies that used discrete trial training as part of the behavioral therapy. The studies measured cognitive, language, and adaptive behavior skills. Four of the best studies were compared to similar studies of standard care; however, there were no significant improvements between ABA therapy and the standard care.
