“…Factor sampling. Karras (1963), Nickols (1962), and Nickols and Nickols (1963) selected subsets of Wechsler scales to represent factors established on the basis of analyses by Cohen (1957aCohen ( , 1957bCohen ( , 1959. Maxwell (1959Maxwell ( , 1960 also presented factor analyses which have suggested SFs.…”

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.

“…Cross validation on 197 subjects indicated that a battery of six subtests yielded better results than previously reported in similar efforts. Karras (1963) and Nickols (1962) also reported sundry combinations that seemed to work with the original samples, but were not crossvalidated. The latter investigator suggested that I and PC "might suffice for gross screening tasks."…”

“…Later items in the WAIS series are, in fact, more difficult than those which appear early in the series. Nickols (1962) noted that the composition of the various subtests are not similar one to the other. On some subtests (e.g., PC, I, C, and V), subjects manifest greater proclivity to pass items at a higher level after failing items in the same subtest presented earlier in the series.…”

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.

“…A different line of studies has been concerned with so-called "short forms": abbreviated scales intended to yield close equivalents of the Full Scale IQ. Although originating in a different context, one may view short forms factor analytically as abbreviated "General Factor" measures (e.g., Nickols, 1962).…”

This paper is a reaction to the extensive literature on new Wechsler subtest combinations (e.g., short forms and factor scales). Any new Wechsler composite raises elementary issues of reliability, validity, and score standardization. It is argued that in the past, these issues have not been dealt with in a satisfactory manner. Reliability and validity formulas, appropriate for Wechsler composites, are presented. A modified part-whole correlation formula is offered for use in cases of nonindependent test administration of part and whole. In order to facilitate appropriate clinical use, conversion tables are presented for the transformation of composite scores-including factor scores-into Wechsler Deviation Quotients.
