Evaluation of a Changing Criterion Intervention to Increase Fluent Responding with an Elementary Age Student with Autism, Summarized Apr 9, 2009

Discrete trial training may help students with autism learn to give fluent answers.

This study looked at the effect of rewards on building fluent response in a student with autism. The intervention worked and taught the elementary school-aged student to give many fluent responses. The student learned rather quickly (4 months) how to give fluent responses. The study was designed to allow the authors to make causal statements about the intervention. The study was limited because it had only one student and no formal data were collected on how well the intervention was done. Read more...

Brief Report: Toward Refinement of a Predictive Behavioral Profile for Treatment Outcome in Children with Autism, Summarized Mar 27, 2009

Future research may allow therapists to know in advance which type of applied behavior analysis (ABA therapy) is most likely to work for any given child with autism.... The authors were able to predict which children would respond to pivotal response training, but not which ones would respond to discrete trial training. The authors note that all children were first exposed to pivotal response training and then to discrete trial training and this may have influenced the results.... Read more...

Treatment Controversies in Autism, Summarized Mar 17, 2009

Research suggests that behavioral autism therapies (discrete trial training and naturalistic strategies) may be most helpful for children with autism.

This review article describes autism therapies and the research behind the therapies. The author calls on parents to avoid sensory integration therapy, diet therapy, and vitamin therapy. She notes that applied behavior analysis (ABA therapy) can improve autism symptoms and some children can make large gains with early ABA intervention. Above all, the therapy should be tailored to the child and the family. She calls for more research and careful thinking in order to find new treatments and test whether or not new treatments work.
