“…The use of only "starred" items in the administration of the S-B may also fall into this category (e.g., Birch, 1955;Wright, 1942). Wolfson and Bachelis (1960) sampled items from selected scales to produce a SF for the WAIS Verbal Scale.…”

“…Scoring times will also differ: some Wechsler subtests are notoriously difficult to score. No evidence is offered on this point, but it is clear that both scoring times and scoring errors could be reduced by judicious choice of subtests and by the use of modified scoring methods (e.g., Blackburn & Benton, 19S7;Carkhuff, 1962;Jastak & Jastak, 1964;Walker, Hunt, & Schwartz, 1965;Wolfson & Bachelis, 1960).…”

Studies are reviewed in which some well-known clinical tests of intelligence are abbreviated to save testing time. Serious methodological problems are evident in most of these studies: samples are often small, unrepresentative, and heterogeneous in composition; and short-form validity is systematically overestimated. It is argued that present statements of the problem do not lead to a unique solution. The general requirement that an abbreviated test should save time while retaining maximum validity cannot be satisfied in the absence of a statement about the relative utility of "time saved" and "validity lost." Future research should benefit by adopting a decision-theoretic approach to the validation of short-form tests.

“…Using selected subtests, as Rabin (1943) did, is not the only method of abbreviating the original scale, nor is it necessarily the best. Wolfson and Bachelis (1960) observed that that method necessarily limits the variety of mental processes sampled, whereas using selected items on each of the subtests (reducing the length of the subtests rather than their number) could tap the whole variety of functions contained in the original scale. They proposed a short form of the Verbal scale of the Wechsler Adult Intelligence Scale ( WAIS ; Wechsler, 1955) based on that premise, and Satz and Mogel (1962) extended their work to the Performance scale of the WAIS .…”

The literature on short forms of individual intelligence tests-Wechsler's scales in particular-is critically reviewed. The review is structured around four choice-points faced by those who study short forms: how to abbreviate the original scale, what kind of subject sample to use, how to estimate IQs on the original scale, and what criteria to apply in evaluating a short form. The review concludes with some reflections based on more than 20 years of research on short forms and the posing of two questions about which little is yet known.Short forms have a long history. Doll (1917) proposed a brief Binet-Simon scale not long after Goddard introduced that scale into the United States and more than 20 years before Wechsler (1939) published the Wechsler-Bellevue Intelligence Scale (W-B). In the present article, however, the focus is on short forms of Wechsler's scales, although most of what follows can be generalized to short forms of any intelligence test constructed along similar lines, that is, as a multitest battery. My purpose is to review what we know about such short forms and how we came to know it, for the benefit of both clinical practitioners and clinical investigators, psychologists who use short forms and psychologists who study them. How Wechsler Viewed Short FormsIn discussing the legitimacy of using short forms, Wechsler (1958) made a distinction based on the use to be made of the results. If all the examiner wants is an IQ for screening purposes, Wechsler observed that there are combinations of three subtests, and even some combinations of two subtests, that may suffice. For anything beyond that, he did not recommend short forms. His view was that an intelligence test should and can give the examiner much more than an IQ (e.g., an evaluation of an individual's strengths and weaknesses), and for that purpose the need was for more testing, not less. Later, Wechsler (1967) appeared to adopt a somewhat harder line, stating that "reduction in the number of [subtests] as a time-saving device is unjustifiable and not to be encouraged" (p. 37) and advising those who ask what one is to do when there is not enough time, to "find the time" (p. 37). How Others Have Viewed Short FormsOthers who have examined the literature on short forms have given them rather mixed reviews. Tellegen and Briggs (1967)

“…Interest in abbreviated forms of the WAIS continues, although the number of publications in this area is moderate. A new approach to the design of short forms was represented in the publication of Wolfson and Bachelis (1960) and in several other reports that followed a similar procedure. The innovation consists of the reduction of the number of items to be administered within subtests, in addition to the reduction of the number of subtests themselves.…”

The past S years of research with the adult Wechsler scales is critically reviewed. Most investigators used the most recently developed scale, the Wechsler Adult Intelligence Scale. Topical coverage includes: comparative validity; short forms; special populations and applications; refinements and critiques; personality correlates; investigations of diagnostic value; special diagnostic groups; and scatter, patterns, and diagnosis. The 197 articles reviewed show that there is no diminution in the number of researches in the area. While the quality of the research has improved, too many investigators repeat the errors contained in earlier studies, despite the periodic publication of these critical reviews.
