Abstract

The Wechsler-Bellevue Intelligence Scales were given to 76 schizophrenics, 25 manic-depressives, and 92 normal student nurses. The psychotics scored best in information tests, and lowest in "Digit Symbols" (requiring new associations). The schizophrenic group had higher verbal than performance IQ's; the manic picture is significantly the reverse. An index utilizing the ratio between scores on the tests in which the schizophrenics did best and those in which they scored lowest, serves to distinguish clearly among the 3 groups. This index may be of value in resolving borderline diagnostic problems. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
