Compared the Performance IQ(PIQ) > Verbal IQ(VIQ) scales of the Wechsler Adult Intelligence Scale with type of crime, ethnicity, and reading disability in a corrections sample of 70 men. Analyses indicated the significant relationships between PIQ > VIQ and type of crime and reading disability may be independent of ethnicity and each other.…

Analysis of correlations between Verbal and Full Scale IQ scores for 231 high-IQ psychiatric outpatients indicated that Verbal IQ appears partially valid as a WAIS short form for this higher IQ group. Results are interpreted in terms of Resnick and Entin's short form validity criteria. (Editor/SJL)

This study tested competing interpretations of IQ deficit in schizophrenic patients. One interpretation (concomitancy hypothesis) holds that IQ loss is a product of schizophrenic symptoms and is remedied as the symptoms remit. The second (prodromal hypothesis) holds that IQ deficit preceeds and facilitates the development of schizophrenic disorder…

Investigated the Luria-Nebraska Intellectual Processes Scale (IPS) as a predictor of Wechsler Adult Intelligence Scale (WAIS) IQs among alcoholic inpatients. Strong correlations were found between IPS and WAIS Verbal IQ and Full Scale IQ; however, the correlation with Performance IQ was only -.41. (NRB)

Examined Shipley-Hartford Scale effectiveness in predicting Wechsler Adult Intelligence Scale-Revised Full Scale intelligence quotients (IQ) in hospital patients (N=156). Analyses revealed overestimation of below average Full Scale IQs, underestimation of above average IQs. Advanced age was associated with low conceptual quotients, suggesting that…

Examined the validity of a subtest combination as an estimate of the Wechsler Intelligence Scale For Children (Revised) Full Scale IQ. Satisfactory correlations were found between the short and full scale IQ. The short form did not allow precise IQ estimation but shows promise as a screening device. (Author)

Estimates were obtained of the effects of ethnic group, sex, education, and clinical diagnosis on WAIS IQ scores of psychiatric patients. Expected IQ scores for segments of the general population were calculated by adding or subtracting these effects from an expected IQ for a White high school graduate. (Author/SJL)

Discusses distinction between statistically significant Verbal-Performance IQ discrepancies and frequencies with which such differences occur in Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample, and compares statistically derived and empirically observed WAIS-R Verbal-Performance IQ frequencies. Delineates implications for…

Compared the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised in a sample of 88 adults. Indices of obtained correlation coefficients suggested a high degree of similarity between the two scales. Results also showed that WAIS IQs were significantly higher than corresponding IQs on the WAIS-R. (WAS)

An estimated ITPA Psychological Quotient (PQ) was compared to the WISC-R Verbal, Performance, and Full Scale IQs of developmentally disabled children, ages 6 to 13. The PQ related strongly to Verbal and Full Scale IQs. Implications for diagnosis and screening are discussed. (Author/SJL)

Explored the relationship between the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) for 37 Native American children. The PPVT-R standard scores correlated significantly with the WISCR-R Verbal IQ, Performance IQ, and Full Scale IQ. The mean PPVT-R standard score was significantly…

Estimated age-adjusted Wechsler Adult Intelligence Scale-Revised intelligence quotient (IQ) scores using linear regression techniques and continuous norming of two samples of psychiatric inpatients (total N=150) in Veteran's Administration hospital. Results support use of estimation procedure in clinical and research settings desiring brief but…

Investigated validity of two- and four-subtest combinations as estimates of Wechsler Adult Intelligence Scale-Revised (WAIS-R) Full Scale IQ among clients of low IQ (N=100). Concluded that the four-subtest form was superior as a screening device when complete administration of the WAIS-R is not feasible. (NRB)

Investigated stability of Wechsler Adult Intelligence Scale-Revised intelligence quotients (IQs) for 52 high school students. One-half of subjects were retested after 3 months; other half after 18 months. Stability coefficients were uniformly high for both retest intervals. IQs for males retested after 18 months increased beyond practice effect.…

Provides initial information on the relationship of the Shipley-WAIS Conversion scores to the WAIS-R (Wechsler Adult Intelligence Scale). Results support the need for new conversion norms for Shipley to WAIS-R scores. The old Shipley to WAIS conversion scores overestimated the WAIS-R scores, particularly among lower-functioning inmates.…
