Study of WAIS-R, Quick Test and PPVT IQS for neuropsychiatric patients.
As expected, the PPVT and various forms of the Quick Test, all tests of receptive vocabulary, overestimated the three IQs of the WAIS-R, often by more than half a standard deviation for a small sample (N = 30) of psychiatric in-patients. A restricted range of scores may have contributed to spuriously high correlations among the various measures of IQ.
