A STRUCTURAL EQUATION ANALYSIS OF THE KAUFMAN BRIEF INTELLIGENCE-TESTAND THE WECHSLER ADULT INTELLIGENCE SCALE REVISED

A maximum likelihood confirmatory factor analysis was performed by app lying LISREL VII to the Kaufman Brief Intelligence Test (K-BIT; A. S. Kaufman & N. L. Kaufman, 1990) and Wechsler Adult Intelligence Scale-R evised (WAIS-R; D. Wechsler, 1981). Analyses were designed to determin e which of six hypothesized oblique factor solutions would best explai n the pattern of relationships among different combinations of K-BIT a nd WAIS-R subtests in a neurologically disordered sample (N = 186). Re sults indicated that a 4-factor model including K-BIT Verbal Intellige nce, and WAIS-R Verbal Intelligence, Nonverbal Intelligence, and Freed om From Distractibility factors provided the best fit to the data. The K-BIT Verbal Intelligence factor appeared to have a significant visuo spatial component, calling into question the assumption that the WAIS- R and K-BIT provide equivalent measures of verbal intelligence.
