Intertest Correlations of the Wechsler Intelligence Scale for Children and Two Picture Vocabulary Tests

Abstract

Problem. This study explores the possibility of substituting a brief picture vocabulary test for the Wechsler Intelligence Scale for Children (WISC) with physically disabled children. This analysis of concurrent validity deals with differences in test difficulty, with correlations between the tests, with the efficiency of predicting WISC scores from picture vocabulary scores, and with some incidental retest data.Subjects. All eligible children in a rehabilitation hospital, from six to sixteen years of age, were tested in the study. By eligible we mean that they were capable of taking the WISC. Their disabilities included such diverse conditions as spina bifida, osteochondritis, arthritis, and rheumatic fever. Conditions such as these frequently involve losses of functions which make it difficult, or even impossible, to administer a test like the WISC. Furthermore, there is always the possibility of penalizing a severely disabled child for

The Peabody Picture Vocabulary Test as a measure of general adult intelligence.

“…The present study is a search for a rapidly administrable test of general intelligence for adults to be used in the various units within a large county hospital. Previous investigations offer little evidence bearing directly on the problem, since most of the work done with the PPVT involves comparisons between children's scores on this test and their scores on other tests, such as the Wechsler Intelligence Scale for Children (Dunn & Brooks, 1960;Moed, Wight, & James, 1963).…”

Relationship of Peabody Picture Vocabulary Test and Wechsler Intelligence Scale for Children in an Educable Retarded Group: A Cautionary Note

“…These findings for recarded Ss are also in general agreement with studies of non-retarded populations. Of 14 such studies, only two (Moed, Wright, & James, 1963;Shipe, 1962) report a mean WISC IQ that is higher than the Peabody IQ.…”

Sex-role preferences in preschool children from five subcultures of the United States

“…There is no test-retest reliability reported in the manual. A testretest reliability coefficient of .88 after one year is reported by a recent study (Moed, Wight and James, 1963) which was done with 29 physi cally disabled children. According to another reviewer (Euros, 1966), "Both coefficients of equivalence and temporal stability appear, there fore, to be adequate for such as a short test" (Piers, 1966, p. 821).…”
