Wechsler Adult Intelligence

Performances on the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised (WAIS-R) were compared between groups at different ages. We studied 176 subjects (primarily outpatients) who were referred for assessment of cognitive function. Although all age groups tended to obtain lower scores on the WAIS-R, older subjects were penalized more on Performance and Full Scale IQs when the revised form was used. However, interactions suggest that differences in the scores on the WAIS and WAIS-R in a clinical population may reflect an interaction among age, presenting complaint, and other factors.

Literacy Test

The WAIS, the original edition of the Ohio Literacy Test, and its auditory form were administered to 60 male psychiatric inpatients at the time of hospital admission. Correlations were .54 to .70. Tentative results suggest that this auditory form may have some merit as a quick estimator of WAIS Full Scale IQs.

Repeat Assessment

The present study attempted to ascertain the best estimate of true Wechsler Adult Intelligence Scale-Revised (WAIS-R) Full Scale IQ (FSIQ) when confronted with an individual who recently had been administered the WAIS-R. Sixty-five college undergraduate participants were administered the WAIS-R twice within 14 days. WAIS-R summary scores, factor scores, and short-form estimates obtained from the second assessment were compared to FSIQ at the first evaluation. The results indicated that Verbal IQ, the Verbal Comprehension factor score, and subtracting 6 points from the current FSIQ are the least affected by repeat assessment and the most accurate estimates of FSIQ at the first evaluation. Use of these estimates of FSIQ are encouraged when evaluating an individual who has been administered the WAIS-R in the recent past.

Wechsler Adult Intelligence

Although the Escala de Inteligencia Wechsler (EIWA) has remained the only standard Spanish version of the Wechsler Adult Intelligence Scale (WAIS) and is consequently the most often-used intelligence test with Spanish-speaking clients, little information exists on the psychometric properties of the test beyond the information in the test manual (Wechsler, 1968). There is no information on the validity or reliability of commonly used short forms of the test, the two-test version using Block Design and Vocabulary, and the four-test version using Block Design, Vocabulary, Arithmetic, and Picture Arrangement. Using the statistical data in the test manual, the two-test version yielded reliabilities of .94 to .95 across the three standardization age groups and validity ratings of .92 to .93. Values for the four-test version were slightly higher, and all were comparable to those for the WAIS and WAIS–R. The results suggest that the short forms can be used with the same confidence with the Spanish WAIS as on the WAIS.

Bipolar Patients

SummaryThe possible effects of clinical depression on intellectual function were investigated in unipolar and bipolar patients. Ninety-six hospitalized depressed patients completed the Wechsler Adult Intelligence Scale (WAIS) on admission and 34 were retested on remission. The high average full scale IQs found remained relatively stable throughout, consistent with earlier studies indicating a limited relationship between intellectual function and clinical severity of depression. No evidence was found for retarded psychomotor activity in bipolar groups or increased psychomotor activity in unipolar groups on three WAIS subtests of psychomotor function, but full scale IQ increased slightly in hypomania.

Fluid And Crystallized Intelligence

This study investigates Verbal, Performance, and Full Scale IQ change in an institutionalized mentally retarded population. 402 individuals who had received two routine administrations of either the Wechsler Intelligence Scale for Children or the Wechsler Adult Intelligence Scale and who ranged in age from 11 to 44 were included as subjects. They were divided into six groups (two WISC and four WAIS) and changes in scores were studied using a semi-longitudinal methodology. Contrary to the dominant view suggested by previous research, Full Scale IQ did not decrease with age. There were, in fact, slight increments, larger and more consistent in Performance than Verbal IQ. This differential change is discussed in terms of the Horn-Cattell theory of “fluid” and “crystallized” intelligence.

Future Direction

The current study examined the Flynn Effect (i.e., the increase in IQ scores over time) across all editions of the Wechsler Adult Intelligence Scale (WAIS), Wechsler Intelligence Scale for Children (WISC), and Wechsler Preschool and Primary Scale of Intelligence (WPPSI). By reverse engineering the correlation and scale score transformations from each Wechsler edition’s technical manual, we made a mean and covariance matrix using the subtests and age groups that were in common for all editions of a given instrument. The results indicated that when aggregated, there was a FE of 0.44 IQ points/year. This Wechsler instrument used, however, moderates the FE, with the WISC showing the largest FE (0.73 IQ points/year) and the WAIS showing a smallest FE (0.30 IQ points/year). Moreover, this study found that the amount of invariant indicators across instruments and age groups varied substantially, ranging from 51.53% in the WISC for the 7-year-old group to 10.00% in the WPPSI for the 5- and 5.5-year-old age groups. Last, we discuss future direction for FE research based on these results.

Kaufman Brief Intelligence Test

The Kaufman Brief Intelligence Test detects learning problems of young students and is a screen for whether a more comprehensive test of intelligence is needed. A study to assess whether this test was valid as an adult intelligence test was conducted with 20 undergraduate psychology majors. The correlations between the Kaufman Brief Intelligence Test's Composite, Vocabulary, and Matrices test scores and their corresponding Wechsler Adult Intelligence Scale-Third Edition test scores, the Full Scale ( r = .88), Verbal ( r = .77), and Performance scores ( r = .87), indicated very strong relationships. In addition, no significant differences were obtained between the Composite, Vocabulary, and Matrices means of the Kaufman Brief Intelligence Test and the Full Scale, Verbal, and Performance means of the WAIS–III. The Kaufman Brief Intelligence Test appears to be a valid test of intelligence for adults.
