“…The SF was derived from the American version of the WAIS-R, and likewise, the above-mentioned studies of its psychometric properties were tested on American samples. However, as has been thoroughly discussed and stressed in Lindau and Najstr€ om (2019), neuropsychological test batteries cannot automatically be dislodged from one cultural context to another. Instead, it is necessary to ensure the applicability of the test content, as well as the norms and abbreviations of a scale, to the cultural context in which the battery is to be used.…”

“…Instead, it is necessary to ensure the applicability of the test content, as well as the norms and abbreviations of a scale, to the cultural context in which the battery is to be used. In Lindau and Najstr€ om (2019) the statistical validity of the SF for the WAIS-IV was examined on a Swedish non-clinical sample consisting of 261 individuals ranging in age from 18 to 73 years. In the entire sample, the results were contradictory, showing conformity between Full Scale IQ (FSIQ) of the original version of WAIS-IV and the prorated IQ-values derived from SF, but lacking consistency at the index level.…”

The Wechsler Adult Intelligence Scale, fourth version (WAIS-IV), is a frequently used instrument for neuropsychological assessment. The aim was to assess the degree of conformity between the Scandinavian adaptation of the WAIS-IV and a short form of this scale (SF) in a mixed sample of neurological diagnoses. The SF comprised Block Design, Similarities, Digit Span, Arithmetic, Information, Digit Symbol (in the WAIS-IV named Coding), and Picture Completion, the latter here replaced by Matrix Reasoning. The sample consisted of 150 patients and included multiple sclerosis (n ¼ 27), brain tumor (n ¼ 15), traumatic brain injury (n ¼ 60) and vascular brain damage (n ¼ 48). There was a lack of congruence between the WAIS-IV and the SF in the entire sample, revealing selectively significantly higher scores for the SF on Full Scale IQ (FSIQ) and Processing Speed Index (PSI). On a diagnostic group level, the discrepancies were as follows: in the traumatic brain injury group on FSIQ, Verbal Comprehension Index (VCI) and PSI, in the vascular damage group the FSIQ was significantly higher on SF compared to the WAIS-IV. Since the results revealed several mismatches between the SF and the WAIS-IV, except for the MS and traumatic brain tumor group, there is a lack of interchangeability between these two sets of tests. Thus, generally the SF cannot be recommended as a substitute for the WAIS-IV in this type of mixed Swedish neurological sample. The small sample sizes make the generalizability of this study limited.

“…For example, some chose the subtests according to areas to be assessed or according to characteristics of the sample (Ringe et al, 2002;Ryan et al, 2015). Another precondition has been the presence in the short form of at least one subtest of each index (VCI, PRI, PSI, WMI), to obtain a global vision of the cognitive performance in each domain (Blyler et al, 2000;Lindau & Najström, 2018).…”

“…Nevertheless, it should be noted that these instruments can only be recommended as screening tools that can provide an approximate vision of cognitive functioning and guide subsequent assessment or determine the patient's fit in a specific treatment group (Keefe et al, 2011;Mueller, Schmidt, & Roder, 2015). They should not be used as tools to derive a diagnostic label that may impact the patient's future (Blyler et al, 2000;Grégoire & Wierzbicki, 2009;Lindau & Najström, 2018;van Ool et al, 2018).…”

“…Meanwhile, only one work from the WAIS-IV scale obtained a three-subtest short form to estimate IQ: Block Design-Similarities-Digit Span (Ryan et al, 2015). Finally, eight studies have opted for four-subtest short forms (four of the WAIS-III and four of the WAIS-IV) (Blyler, Gold, Iannone & Buchanan, 2000;Fuentes, Romero, Dasí, & Ruiz, 2010;Grégoire & Wierzbicki, 2009;Lindau & Najström, 2018;Ryan et al, 2015;Schrimsher, O'Bryant, O'Jile & Sutker, 2008;Úbeda et al, 2017;van Ool et al, 2018). The eight forms obtained are different.…”

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.
