Test-retest stability of the Kaufman Assessment Battery for Children (K-ABC) was investigated over a 5 1/2-month interval for 42 Mexican-American preschool/kindergarten children. Results indicated stability coefficients for K-ABC Global scales and subtests were generally of adequate magnitudes providing some evidence that the K-ABC is a relatively…

The Kaufman Assessment Battery for Children is reviewed in terms of technical and theoretical aspects, the issue of cultural bias, its procedure for comparing cognitive performance and academic achievement, and its predictive validity for academic achievement. The paper concludes by summarizing the test's characteristics that should be considered…

Administered the Wechsler Intelligence Scale for Children, Wechsler Intelligence Scale for Children-Revised, and Wechsler Preschool Primary Scale of Intelligence in a counterbalanced design to randomly selected elementary school children (N=72). Results indicated that the verbal Intelligence Quotients (IQs) were comparable, but the performance and…

Samples in research on individual and group differences may be selected based on whole scores which differ from the population mean. Children are diagnosed in clinical practice with a whole score. These procedures produce regression to the population mean which can affect accuracy and adequacy of part score interpretations. (Author/DWH)

Results indicate that because there is not an equivalent relationship between the WISC and WAIS, classification or retardation level and prognostic formulation using these tests should be made cautiously. (Author/CB)

Assessment of reliability and validity of the Arthur Adaptation of the Leiter International Performance Scale and the Peabody Picture Vocabulary Test when used with preschool language delayed children showed both stable, but the former much more predictive of later functioning on the WISC and a broader measure of intellectual functioning.

Compared the Wonderlic Personal Test and the Wechsler Adult Intelligence Scale for a sample of 30 adults first tested in 1976. The two tests were similar in reliability of clinical classification, but the Wonderlic demonstrated fewer practice effects. Despite its ease of administration, Wonderlic intelligence estimates appear stable. (Author/JAC)

An examination of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtests and intelligence quotients in a diagnostically heterogeneous sample of patients referred for psychological or neuropsychological evaluation found that reliabilities and standard errors of measurement approximated normative group reports. WAIS-R is a reliable…

The WISC-R was investigated by using measures of profile (multivariate) reliability to determine its most reliable dimensions and the precision and similarity of the multivariate structure across age groups. The structure of the WISC-R subscales was stable across age groups. Two strategies for the interpretation of WISC-R profiles are offered.…

Inmates score significantly lower on the second edition (BETA II) than on the first edition (BETA I), regardless of the order of administration. BETA I score distributions were unaffected by the order of administration. BETA II score distributions depended on whether BETA II was administered first or second. (Author)

Wechsler Intelligence Scale for Children-Revised (WISC-R) test-retest data with a six-month interval were obtained for 45 normal l0-year-old children. Verbal IQ estimates were stable, but significant practice effects were obtained on performance and full scale IQ estimates. Discussion focused on test readministration. (Author/RL)

Demonstrates how data smoothing procedures--procedures commonly used in the development of continuous test norms--can provide better estimates of the reliability, uniqueness, and general factor characteristics for the Wechsler Intelligence Scale for Children, third edition, subtests. Suggests that such procedures are applicable to other test…

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.…

Investigation of the stability of Wechsler Adult Intelligence Scale Revised scores of 25 college students over a 4-year period found that global and subtest scores were highly stable. Subtest scores tended to be higher on the retest, but global scores were not despite four years of educational experiences between test administrations. (Author/DB)
