Popular Autism Treatment Lacks Scientific Evidence

AUSTIN, Texas — One of the most popular intervention therapies for children with autism spectrum disorders (ASD) lacks scientific support according to a literature review published by University of Texas at Austin Mark O'Reilly and an international team of scientists. The researchers reviewed 25 major studies on sensory integration therapy (SIT) to see if the current evidence base supports use of this therapy in the education and rehabilitation of children on the autism spectrum. Their conclusion that research does not support the use of SIT means providers who work with children with ASD will need to reassess their education and treatment strategies. Many agencies serving children on the autism spectrum are mandated to use research-based, scientifically valid interventions, but several previous surveys indicate SIT remains one of the most common intervention choices. In one study, 99 percent of ed occupational therapists reported using it. "According to the Diagnostic and Statistical Manual of Mental Disorders, or DSM, a person has to have severe communication and social deficits as well as restrictive and repetitive behaviors to be diagnosed with ASD," said O'Reilly, interim chair of the College of Education's Department of Special Education. "SIT was proposed as a way to help with these symptoms.
