Previous research on populations with conduct problems has shown a tendency for these groups to obtain significantly higher Peformance than Verbal Scale IQ's on the Wechsler Intelligence Scales. The purpose of the present study was to update previous research by using DSM III diagnosed patients and the revised Wechsler Scales. Futhermore, the present study analyzed Wechsler subtest scores as well as Scale IQ's. Scores for 330 adolescents admitted to a private psychiatric hospital were investigated. Eighty-four subjects, who were diagnosed Conduct Disorder, Oppositional Disorder, Antisocial Personality Disorder, Adjustment Disorder with disturbance of conduct, or Explosive Disorder, served as the experimental group. Adolescents with other diagnoses, exclusive of these, served as the clinical control group. Results show that male subjects in the experimental group obtained significantly lower mean scaled scores on the Comprehension subtest compared to the Picture Arrangement subtest and significantly lower Verbal than Performance Scale IQ's. Present findings suggest that these patients are especially weak in the knowledge or abilities measured by the Comprehension subtest.
