Performances of adult patients on the Bellevue Intelligence Scales and the Revised Stanford-Binet

The Wechsler Intelligence Scale for Children and the Revised Stanford-Binet.

“…That the performance scale does not correlate as well with the Binet as does the verbal scale is to be expected in the light of the lesser proportion of such material in the Binet. This same trend, of the performance correlation being lower than the verbal, has been found with the adult Wechsler scale and the Binet [1,2]. In Table 2 are listed mean IQ scores, standard deviations, and ranges of scores of the total population and of the subgroups.…”

“…Similar studies are found in the literature, wherein the Stanford-Binet, Form L, 1937 Revision, is compared to the Wechsler-Bellevue Intelligence Scale for Adults [1,3] and for Adolescents [2,6]. In some of these studies, provisional scales of equivalent scores were computed for Wechsler-Bellevue IQ's from a knowledge of Stanford-Binet IQ's.…”

The use of the Wechsler-Bellevue scales with normal and abnormal persons.

“…1. Means of subtexts for the groups have been used as the only (4,5,8) or partial (11,20) basis for the comparison.of groups. This method is especially vulnerable and unreliable when the age and intelligence as well as cultural background factorsare poorly controlled or not controlled at all.…”

Chapter II: Current Construction and Evaluation of Intelligence Tests

“…A number of studies (2,4,7,8,9,10,35,46,56) comparing old and revised Stanford-Binet, short and long forms of Stanford-Binet, Stanford-Binet with Kuhlmann-Anderson, Kuhlmann Tests of Mental Development, Wechsler Bellevue and Kent EGY Tests have appeared. They agree that tests cannot be used interchangeably and that caution must be exercised in interpreting IQ's because of the dissimilar variability of different tests.…”
