Abstract
This study examined childhood behavior problems in schizophrenic patients and their healthy siblings. Childhood Behavior Checklist (T. Achenbach, 1991) ratings were obtained from retrospective maternal reports, for 4 age periods: birth to 4 years, 4 to 8 years, 8 to 12 years, and 12 to 16 years. The results indicated that the patients had a variety of childhood behavior problems when compared to their siblings and that the various types of problems differed in their developmental course. Cluster analysis was conducted on the childhood behavior ratings for the schizophrenic patients, and 2 subgroups emerged. Cluster I showed more pronounced behavioral problems than Cluster II, and some of these problems were apparent in early childhood and increased with age. Cluster I also demonstrated greater neuromotor abnormalities in childhood.Keywords
