Normative comparisons are an integral component of neuropsychological test interpretation and provide the basis for an inference of abnormal function and impairment. In order to remedy a deficit of normative standards for a large number of neuropsychology tests, Mitrushina, Boone, Razani, and D'Elia (2005) used the meta-analysis of studies that…

In a cross-validation of results from L. O. Graue et al. (2007), standard psychological assessment instruments, as well as tests of neurocognitive and psychiatric feigning, were administered under standard instructions to 24 participants diagnosed with mild mental retardation (MR) and 10 demographically matched community volunteers (CVH). A 2nd…

A. S. Kaufman (1994) recommended that clinicians substitute Symbol Search, a new subtest, for the Coding subtest when calculating Performance and Full Scale IQs on the Wechsler Intelligence Scale for Children-III. Tables are provided for accurate derivation of IQs, percentile ranks, and confidence intervals when this substitution is made. (SLD)

Although attention has been given to the intellectual functioning of children with attention-deficit/hyperactivity disorder (ADHD) relative to their non-ADHD peers, few studies have examined intellectual functioning in adults with ADHD. The purpose of the current investigation was to examine differences in intellectual ability between adults with…

The incremental validity of factor scores from the Wechlser Intelligence Scale for Children-III (WISC-III) in predicting scores on the Wechsler Individual Achievement Test (WIAT) was studied in 283 nonreferred children and 636 referred for evaluation. The Full Scale IQ of the WISC-III was the best predictor of WIAT achievement. (SLD)

Composite reliability and standard errors of measurement were computed for prorated Verbal, Performance, and Full-Scale intelligence quotient (IQ) scores from a seven-subtest short form of the Wechsler Adult Intelligence Scale-Revised. Results with 1,880 adults (standardization sample) indicate that this form is as reliable as the complete test.…

Validity of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) intersubtest scatter as an indicator of cognitive impairment due to brain dysfunction was studied with 316 brain-damaged men. When compared with the WAIS-R standardization sample, intersubtest scatter was not greater for normal persons of similar intelligence quotient. (SLD)

Whether external validity of intelligence quotient (IQ) scores from the Wechsler Intelligence Scale for Children--Revised is moderated by reading ability was studied with 382 Canadian elementary school students. Little evidence was found that IQ scores had less concurrent validity for poor readers. Implications for remedial services provision are…

The predictive power of the short-form Wechsler Adult Intelligence Scale of P. Satz and S. Mogel to provide equivalent information about IQ scores and age-corrected scale scores was not differentially affected by the side of the lesion for 63 patients with brain tumors. (SLD)

The concurrent validities of 3 short forms of the Wechsler Adult Intelligence Scale (WAIS) were compared for their prediction of full-scale IQ for 145 male and 159 female psychiatric inpatients. Results support previous research showing better predictive accuracy for L. C. Ward's (1990) seven-subtest short form than the others. (SLD)
