Correlated and factor analyzed WISC-R and Peabody Picture Vocabulary Test (PPVT) scores of 100 adolescent psychiatric patients. The purposes were to explore the factor structure of these scores among a psychiatric sample for comparison with other samples in the literature and to determine whether the PPVT adds sufficient information to an intellectual assessment battery. Three factors emerged that were similar to previously reported factors using other Ss. The PPVT loaded heavily on the factors emerging from the WISC-R, suggesting that the PPVT adds little to information gained from the WISC-R.
