The study was planned to investigate the effect of a sensory integration therapy program on sensory problems of children with autism. This study was conducted at the Trakya University Training and Research Center for Mentally and Physically Handicapped Children in Turkey. The children were separated into two groups, each comprising 15 children between 7 and 11 years of age with autism, according to DSM-IV criteria. The children in each group were assessed initially on a checklist, Sensory Evaluation Form for Children with Autism, developed to evaluate sensory characteristics of children with autism, and at the end of the study, participants were assessed again on the checklist. Statistically significant differences between groups indicated that the sensory integration therapy program positively affected treated children.
