Treatments for autism: parental choices and perceptions of change.

Empirically conducted studies of the efficacy of various treatments for autism are limited, which leaves parents with little evidence on which to base their treatment decisions (Kasari, Journal of Autism and Developmental Disorders, 32: 447-461, 2002). The purpose of this study was to examine the types of treatments in current use by families of children with ASD. In addition, parents' perceptions of improvement in their child's functioning were explored.
