Diagnostic importance of combined parent and teacher ratings on the Revised Behavior Problem Checklist.

ABSTRACT

The Revised Behavior Problem Checklist (RBPC) was completed by parents and teachers for 105 child psychiatry outpatient boys aged 6 to 12 years. In addition, DSM-III diagnoses were determined independent of checklist results, and the children were divided into major diagnostic groups of externalizing, internalizing, and mixed disorders. Combined parent and teacher ratings proved more effective than separate ratings in distinguishing the externalizing and mixed groups from the internalizing group on the RBPC externalizing factors. The overall classification of individual boys with discriminant function analysis increased from 72% to 83% when the ratings of both parents, rather than one parent, were combined with teacher ratings. Enhancing diagnostic accuracy of type of psychiatric disorder by using combined parent and teacher behavior checklist ratings is discussed.
