[Reliability of the Child Behavior Checklist in a population of 6 to 8-year-old special education students].

66 children attending first grade at a special school for educationally subnormal children were examined medically and psychologically. Classification was done according to ICD-10. In addition, the parents were asked to rate their children's behavior with the "Child Behavior Checklist" by Achenbach and Edelbrock. The most common symptoms rated in this group of 6- to 8-year-old children were lack of concentration, speech and language problems, hyperactivity, demand for attention and arguing. The mean total score (cut-off score: 30) and the number of crucial items (cut-off score: at least two crucial items) differed significantly between the children with and those without psychiatric disorders. No significant correlation was found between the mean total score or the number of crucial items and the sex of the children or the other axes of the Multi-axial Classification of Child Psychiatric Disorders.
