Abstract	The fourth edition of the Wechsler Adult Intelligence Scale (WAIS-IV) is a revised and substantially updated version of its predecessor. The purposes of this research were to determine the constructs measured by the test and the consistency of measurement across large normative and clinical samples. Competing higher order WAIS-IV four- and five-factor models were analyzed using the WAIS-IV's sample of 1,800 normative adults and 411 clinical adults. When all 15 WAIS-IV subtests were considered, both four- and five-factor models were suitable, but the five-factor model provided a better fit. The WAIS-IV PRI differentiated into two composites as follows: POI(Gv) consisting of Block Design, Visual Puzzles and Picture Completion; and FRI(Gf) consisting Matrix Reasoning, Arithmetic and Figure Weights. The five-factor solution included Quantitative Reasoning (RQ), consisting of Arithmetic and Figure Weights, as a narrow ability subsumed under FRI(Gf). Arithmetic, Vocabulary, and Figure Weights subtests had the highest "g" loadings. Cancellation had the lowest "g" loading. The WAIS-IV generally demonstrated full factor invariance between clinical and nonclinical samples. (Contains 6 tables, 2 figures, and 3 notes.) (As Provided).
