The effects of extended time on the writing performance of university students with learning disabilities (LD) was examined. Thirty-eight students (19 LD; 19 non-LD) completed a collection of cognitive, linguistic, and literacy measures, and wrote essays under regular and extended time conditions. Limited evidence was found to support the…

In administration of individually administered intelligence tests, items are commonly presented in a sequence of increasing difficulty, and test administration is terminated after a predetermined number of incorrect answers. This practice produces stochastically censored data, a form of nonignorable missing data. By manipulating four factors…

In tests with time limits, items at the end are often not reached. Usually, the pattern of missing responses depends on the ability level of the respondents; therefore, missing data are not ignorable in statistical inference. This study models data using a combination of two item response theory (IRT) models: one for the observed response data and…

A historical increase in the number of factors purportedly measured by commercial tests of cognitive ability may result from four distinct pressures including: increasingly complex models of intelligence, test publishers' desires to provide clinically useful assessment instruments with greater interpretive value, test publishers' desires to…

Formulas for estimating the validity of random short forms were applied to the standardization data for the Wechsler Adult Intelligence Scale-Revised, the Minnesota Multiphasic Personality Inventory, and the Marlowe-Crowne Social Desirability Scale. These formulas demonstrated how much "better than random" the best short forms of these…

The Kaufman Brief Intelligence Test (K-BIT) (A. S. Kaufman and N. L. Kaufman, 1990) was compared with short forms of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) using results from 64 referrals to a neuropsychology service. Advantages of each test are noted and their use discussed. (SLD)

The validity of a four-subtest short form of the third edition of the Wechsler Intelligence Scale for Children (WISC-III) and the Kaufman Brief Intelligence Test (K-BIT) was evaluated with 42 adolescent offenders. Findings support the clinical use of the short form as a good estimate of WISC-III full-scale IQ. (SLD)

The Satz-Mogel Abbreviation of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) was compared with a 7-subtest short form of 130 healthy and 40 neurologically impaired older adults. Both short forms were found similar for normal or impaired adults in comparison with the full WAIS-R. (SLD)

Eight subtests were selected from the Wechsler Intelligence Scale for Children--Third Edition (WISC-III) to make a short form for clinical use. Results with the 2,200 children from the WISC-III standardization sample indicated the adequate reliability and validity of the short form for clinical use. (SLD)

Validity and reliability were calculated from data in the standardization sample of the Wechsler Adult Intelligence Scale--Revised for 565 proposed short forms. Time saved in comparison with use of the long form was estimated. The most efficient combinations were generally those composed of subtests that were quick to administer. (SLD)

The calculations of D. Schretlen, R. H. B. Benedict, and J. H. Bobholz for the reliabilities of a short form of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) (1994) consistently overestimated the values. More accurate values are provided for the WAIS--R and a seven-subtest short form. (SLD)

This study used 126 young adult black and white male inmates to test the comparability of the Pauker and Statz and Mogul short forms with the standard Wechsler Adult Intelligence Scale (WAIS). The Pauker form was superior with this population. Findings should not be generalized to other ages, races, or to women. (Author/CP)

Techniques for constructing short forms of tests are discussed, and an example is given using the Wechsler Adult Intelligence Scale-Revised. Reliability and validity estimation equations are presented. (GDC)

The concurrent validity of 2 brief intelligence tests, the Matrix Analogies Test-Short Form (MAT) and the Kaufman Brief Intelligence Test (K-BIT) with the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) using a sample of 50 urban students. The MAT and K-BIT appeared equally useful as screening tests. (SLD)

Compared area scores from short-form version of Stanford-Binet Intelligence Test (Fourth) with those from long form for 33 gifted children. Found three of five mean difference contrasts were significantly different and correlation coefficients between corresponding area scores and Test Composite were statistically significant. Suggests that…
