Abstract
Autism characteristics in sixty children (aged from 2 to 8) were assed. Their behavioral symptoms were evaluated using the Autism Treatment Evaluation Checklist (ATEC). ATEC has four main domains of autistic disorders (Speech/Language/Communication, Sociability, Sensory/Cognitive Awareness, and Health/Physical/Behavior) in children with clinical diagnosis by Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and Childhood Autism Rating Scale (CARS) of autism spectrum disorder (ASD). Utilizing ATEC checklist, our study describes significant behavioral observations between autistic children which could effectively contribute to better understanding and treatment during their early intervention stage.
