The purpose of this study was the identification of behavioral problems in children with autism disorders. In total 118 mothers of children between three and fifteen years of age responded to the Child Behavior Checklist. Three groups of children were differentiated: children with autism, children with language disorders, and typical schoolchildren. The autism and language disorder groups had significantly higher average total scores than the typical schoolchildren. The language disorder group had higher average scores on aggressive behavior and externalizing behavior. The children with autism disorders had higher average scores on thought problems and lower scores on anxiety. Children with autism showed different behavioral problems in comparison with the two remaining groups of children.
