“…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.

“…The result is that prorating, while setting the mean IQ of the normative group correctly at 100, tends to inflate the normative standard deviation; in other words, it tends to generate IQ values that are too extreme. This effect may be reflected in some of the reported standard deviations of prorated IQs as compared to Full Scale IQs (e.g., Nickols & Nickols, 1963;Yudin, 1966).…”

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.
