An increasing number of students diagnosed with difficulties such as attention deficit hyperactivity disorder and Asperger?s syndrome are being seen in schools. Sensory integration difficulties may be part of the symptomatology of these disorders. These difficulties may result in difficulties with both classroom behaviors and academic performance. This single-case study investigated the effectiveness of art therapy with a 5-year old white male with sensory integration difficulties. Art therapy focused on preart activities using three media. Teacher ratings assessed classroom behavior for improvement. Each of the varied media sessions was compared to control sessions where a nonart experience was offered. Results indicated an increase in positive behaviors after art sessions as well as postponement of the first incidence of negative behaviors. Art therapy was found to be a useful intervention.
