Short forms of the Wechsler adult scales: a systematic review

Abstract

Introduction. Since the appearance of the first WAIS scale, there has been a widespread attempt by researchers in the assessment of cognitive abilities to find short forms that facilitate the clinical practice of professionals in those situations where conditions, either because of the time available or the clinical characteristics of patients, do not necessitate the use of an extensive tool. Objective. To carry out a systematic review of the short forms of up to four subtests extracted from the WAIS-III and WAIS-IV scales. Method. Search for information in the PsycINFO database and systematic review of the information following the PRISMA guidelines. Results. Of the 47 studies found, 36 were selected for full-text revision, of which 13 were finally included in this review: 6 of the WAIS-III and 7 of the WAIS-IV. Different forms achieved good results in the quality criteria established in a variety of samples. Discussion and conclusion. There are several forms that are useful for estimating the IQ, according to the samples and the quality criteria used.

“…The third strategy relies on a regression-based equation to select the subtests that should be used to estimate FSIQ. While a more extensive review of the different methods to validate short forms of the Wechsler intelligence tests is beyond the scope of this study, these methods—that each have their pros and cons—are reviewed in detail in Jiménez-Bascuñán et al ( 2020 ) and Olivier et al ( 2013 ) (see also King and King 1982 ; Levy 1968 ; Silverstein 1990 ). Short forms that reduce the number of items rather than the number of subtests are less reliable than those that combine four or five subtests ( Silverstein 1990 ); therefore, in this study, we compared several sets of subtests of the WAIS-IV-ID to estimate the FSIQ using the regression-based approach.…”
