A Case Study of IDP (Interactive Developmental Play Therapy) for School-Aged Children with Autism Spectrum Disorder

This study is a case study that analyzed the effects of Interaction Developmental Play Therapy(IDP) to improve sensory regulation and social adaptation ability of school-age children with autism spectrum disorder. The subjects of the study were five elementary school students belonging to a support organization for children with severe ASD in P city, Gyeonggi-do, who were all diagnosed with autism with a score of 36 or higher in the Childhood Autism Rating Scale(CARS), and were rated below 50 in the Social Mature Scale(SMS). IDP was conducted three times a week from December 2022 to February 2023, a total of 18 sessions, and changes in sensory regulation and social adaptation ability were measured through pre and post-evaluation. In conclusion, IDP can be seen as having a positive effect on the development of sensory regulation ability and social adaptation ability of school-age ASD children.
