The WAIS-III is a well-established tool for assessing intellectual functioning in a wide range of patient populations. However, it may often be impractical to administer the entire WAIS-III protocol due to time constraints or the need to focus the assessment on other specific neuropsychological domains. A solution for this has been the use of abbreviated forms of the . WAIS-III. Wymer, Rayls, and Wagner (2003) developed a clinically derived abbreviated form of the WAIS-III that addresses weaknesses found in previous abbreviated forms and concerns the authors observed during administration of the WAIS-III. This archival study examines the utility of the Wymer, et al. (2003) abbreviation in a large clinical population and also explores the accuracy of using four subtests (Vocabulary, Similarities, Block Design, and Matrix Reasoning) or two subtests (Vocabulary and Block Design) to estimate IQ scores. Results suggest the Wymer, et al. · (2003) short form provides a reliable and valid estimate of scores while reducing administration time by nearly 50%. The four-subtest and two-subtest abbreviations had a high rate of overestimation and therefore should only be used when general estimates of IQ are needed.
