Scoring reliability on the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III).

Nineteen psychologists and 19 graduate students scored two Wechsler Adult Intelligence Scale-Third Edition patient protocols. Mean IQs and indexes were similar across groups, but the ranges for Verbal IQ (VIQ), Performance IQ (PIQ), and Full Scale IQ (FSIQ) on one protocol were 25, 22, and 11 points, respectively. For both protocols taken together, percentages of agreement with the "actual" IQs...

Structural and incremental validity of the Wechsler Adult Intelligence Scale-Fourth Edition with a clinical sample.
