[Subgroups of hyperkinetic disorders--explorative studies with reference to questionnaires and immunologic parameters].

In this paper, the main questions examined are: 1. The relationship between clinically diagnosed hyperkinetic syndrome (HKS) and 3 questionnaires for parents (Child Behavior Checklist (CBCL) by Achenbach and Edelbrock, Enzephalopathie-Fragebogen by Meyer-Probst and 10-Item scale by Conners). 2. The relationship between the clinical psychiatric diagnosis and the questionnaires and allergological parameters. In order to answer these questions, a sample of 122 psychiatric patients with "extraversive" behavior disturbances (HKS: N = 104, other "extraversive" disorders, mainly conduct disorders (EVD): N = 18) was examined prospectively and sequentially. The preliminary results are: a) The children with HKS, the children with EVD and the children with HKS and conduct disorder could be differentiated by several subscales (Especially by "introversive" symptoms) of the CBCL and the Fragebogen by Meyer-Probst. The Conners scale showed significant differences between the groups on only one item. b) The children with HKS, especially those without conduct disorder, had two to three times as many allergies as the children with HKS and conduct disorders or those with EVD.
