A structural equation analysis of the Kaufman Brief Intelligence Test and the Wechsler Adult Intelligence Scale-Revised

Article Abstract:

It is hypothesized that Wechsler Adult Intelligence Test-Revised (WAIS-R) and Kaufman Brief Intelligence Test (K-BIT) provide equivalent measures of intelligence in a neurologically disordered sample. This proposition is tested using six latent-variable models. The predictive validity of the six hypothesized oblique factor solutions is evaluated. Findings suggest that a four-factor model consisting of K-BIT Verbal Intelligence, WAIS-R Verbal Intelligence, Nonverbal Intelligence, and Freedom From Distractibility provided a better fit to the research data.

Computation of Wechsler Adult Intelligence Scale-Revised factor scores: equal and differential weights

Article Abstract:

Factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) are commonly computed using procedures involving equally weighted sums of the subtests that load the highest on the estimated factor. It is contended that this approach is flawed because the factor scores generated do not have discriminant validity. The statistical consequences of using equal weights in estimating the WAIS-R factors scores are examined.

Psychometric adequacy and comparability of the short and full forms of the Personality Assessment Inventory

Article Abstract:

The adequacy and comparability of the full and short forms of the Personal Assessment Inventory (PAI) were evaluated through a study in terms of a wide range of psychometric characteristics. Results of the 421 participants who completed the full form as part of a neuropsychological evaluation indicated slightly lower internal consistency reliability of the short form compared with the full form.
