Current taxonomies of intelligence comprise two factors of mental speed, clerical speed (Gs), and elementary cognitive speed (Gt). Both originated from different research traditions and are conceptualized as dissociable constructs in current taxonomies. However, previous research suggests that tasks of one category can be transferred into the…

Investigated optimal two-, three-, four-, and five-test short forms of the Escala de Inteligencia Wechsler para Adultos (EIWA), the Spanish form of the Wechsler Adult Intelligence Scale (D. Wechsler, 1956). Results with 616 adults suggest that use of the EIWA should be limited to research and tracking cognitive changes over time. (SLD)

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 retest stability of four Wechsler Adult Intelligence Scale-Revised (WAIS-R) short forms (Kaufman, Ishikuma, and Kaufman-Packer; Reynolds, Wilson and Clark; Silverstein; Ward) was investigated with 61 subjects aged 75 to 87 years. Short form stability in each instance was comparable to that of the standard WAIS-R. (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)

Five short forms of the revised edition of the Wechsler Adult Intelligence Scale-Revised were compared for use with an inpatient population. Results with 110 psychiatric inpatients are discussed in terms of trade-offs among administration time, accuracy of IQ estimation, and the clinical value of obtaining scores from the full test. (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)

Three short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R), developed in 1991, were cross-validated on 207 male and 133 female adolescent psychiatric inpatients and outpatients. Results show psychometric properties for the short forms that are comparable to those of the WAIS-R standardization sample. (SLD)

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…

Development of an alternate form of Raven's Standard Progressive Matrices Test is described. Reliability analysis with 449 children of differing racial/ethnic backgrounds showed good reliability and comparable predictive validity. The alternate form is a promising research tool. (SLD)

The predictive power of the Split-Half version of the Wechsler Intelligence Scale for Children--Revised (WISC-R) Object Assembly (OA) subtest was compared to that of the full administration of the OA subtest. A cohort of 218 male and 49 female adolescent offenders detained in a Texas juvenile detention facility between 1990 and 1992 was used. The…

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)
