title: The Performance-Verbal IQ discrepancy in differentiated subgroups of delinquent adolescent boys.
abstract: Evidence for Wechsler's Performance-Verbal IQ sign of adolescent psychopathy in the test results of undifferentiated groups of delinquents has been variable. In view of the heterogeneity of delinquency as a clinical syndrome, the validity of Wechsler's sign was reexamined for psychopathic, neurotic, and subcultural delinquent boys defined according to Quay 's behavioral classification system. Only the psychopathic group scored significantly higher on the Performance Scale than on the Verbal Scale. However, the number of adolescents in each group obtaining higher Performance than Verbal IQs did not significantly differ. Additional group comparisons indicated that the psychopaths earned markedly lower scores on the Comprehension subtest that did the other groups. The findings were interpreted in light of characteristics common to most delinquents regardless of personality orientation.
