“…Still another difficulty with the PPVT IQ as a measure of adult intelligence is the presence of a significant nonlinear relationship between the PPVT IQ and the FIQ of the WAIS-R. This result supports Pool and Brown's (1970) finding with the D-WAIS and suggests that when linear regression is used, PPVT IQ scores would tend to misclassify patients according to FIQ. Altogether, the findings of the present study indicate that the PPVT IQ is not a valid or effective estimator of adult intelligence and is interpreted best as a measure of adult vocabulary skills.…”

“…Problems with this clinical inference have been noted. Pool and Brown (1970), for example, cautioned that the PPVT IQ does not accurately classify adult patients according to D-WAIS IQ (Doppelt Short Form), probably in relation to a significant nonlinear cubic relationship between the two IQ scores. PPVT IQ scores also tend to overestimate Wechsler IQ scores for both children (Shaw, Matthews, & Kliive, 1966) and adults (Maloney et al, 1978).…”

Used partial correlation and multiple regression procedures to test the hypothesis that the PPVT IQ assesses more than vocabulary in adults. Ss were 84 inpatients from psychiatry and neurology wards. The relationships between the PPVT IQ and other measures of vocabulary, intelligence, memory, visual‐motor speed and education were examined in the statistical analyses. Although these variables have significant simple correlations with the PPVT IQ, the multivariate analyses show that the Vocabulary Subtest of the WAIS‐R is the only important variable. No other variable or variable combinations are able to account for further PPVT IQ variance after the effect of the Vocabulary Subtest is removed. The results support the use of the PPVT as a test of adult vocabulary, but not adult intelligence, and suggest that the PPVT may be useful as part of language assessment in patients with expressive language disorders.

“…Research on correlations of WAIS Verbal and Full Scale IQ with such tests as the Shipley-Hartford Institute of Living Scale, the Peabody Picture Vocabulary Test, Raven's Progressive Matrices, Ammons' Full Range Picture Vocabulary Test, and the Quick Test shows correlations generally ranging from around .73 (Bartz, 1968;Mack, 1970) to near .90 (Pool & Brown, 1970;Sydiaha, 1967). In light of these findings, the Prifitera and Ryan (Note 1) findings of correlations of -.86 and the present findings of correlations of -.84 between the Luria-Nebraska Intelligence scale and both the WAIS VIQ and FSIQ indicate that the Intelligence scale is likely to provide as good an estimate of WAIS IQ scores as do other brief tests of intelligence currently in use.…”

The present study is an attempt to cross-validate and extend an earlier study of correlations of the Luria-Nebraska Neuropsychological Battery with the Wechsler Adult Intelligence Scale (WAIS). In a sample of 280 psychiatric, neurologic and normal subjects Verbal IQ correlated -.84, Performance IQ -.74, and Full Scale IQ -.84 with the Intelligence scale, results very similar to those of Prifitera and Ryan. Equations for estimating IQ scores from the Intelligence scale were derived that were similar to equations derived by Prifitera and Ryan. Equations for estimating IQ scores were also derived from the first three Luria-Nebraska Neuropsychological Battery scales to emerge in stepwise multiple regression analyses, resulting in improved estimations of IQ. Correlations between individual Luria-Nebraska Neuropsychological Battery scales and WAIS subtests are reported and their implications discussed. The present findings indicate that the Luria-Nebraska Neuropsychological Battery can provide useful estimates of summary WAIS IQ scores.

The Wechsler Adult Intelligence Scale (WAIS) is used only sparingIy in most institutional settings because of its time-consuming nature. I n a search for an adequate but efficient substitute, the authors have instituted three evaluations of the relationships between potential WAIS-substitutes and the WAIS itself. The present report describes the first of these researches-a study of the relationships between the four group ability tests and the WAIS in a mental hospital setting. The four were chosen because they are all relatively short and have shown promise in earlier research. They are the Science Research Associates (5)
