Comparisons of the Vocabulary Scores and IQs on the Wechsler Intelligence Scale for Children—III and the Peabody Picture Vocabulary Test—Revised

The Wechsler Intelligence Scale for Children—III and the Peabody Picture Vocabulary Test—Revised were given to 33 children (15 boys, 18 girls) who were enrolled in Grades 3, 4, and 5. The statistically significant correlations of .75, .76, and .60, respectively, between the Peabody Standard Score Equivalents and the Wechsler Vocabulary subtest scaled scores and the Wechsler Verbal and Full Scale IQs suggest that the Peabody appears to be a satisfactory screening test of intelligence for use with children in these grades.

Comparisons of the IQ and vocabulary scores on Wechsler Preschool and Primary Scale of Intelligence-Revised and Peabody Picture Vocabulary Test-Revised

The Wechsler Preschool and Primary Scale of Intelligence-Revised and the Peabody Picture Vocabulary Test-Revised were administered to 51 preschool, kindergarten, first-grade, and second-grade students. Although 2 of 4 Pearson correlations between these two instruments were statistically significant, they may not be of practical significance.

Relationships between Scores on Stanford-Binet IV and Wechsler Intelligence Scale for Children—Revised

Estimations of some relationships among scores on the “General Purpose Abbreviated Battery” of the Stanford-Binet: Fourth Edition and the Wechsler Intelligence Scale for Children—Revised were based on responses of a third-grade class of 11 boys and 12 girls who took both tests. Of 5 Pearson correlations of the total scores and of four pairs of subtests 3 were statistically significant. The Binet IV seems to hold promise for the examiner in the field although there are several points to ponder.

Correlations between Scores on the Wechsler Intelligence Scale for Children-III and the General Purpose Abbreviated Battery of the Stanford-Binet IV:

Estimations of some relationships among scores on the “General Purpose Abbreviated Battery” of the Stanford-Binet: Fourth Edition and the Wechsler Intelligence Scale for Children-III were based on the responses of 14 boys and 18 girls enrolled in Grades 3, 4, and 5 and who took both tests. Of 13 Pearson correlations between the Binet IV composite score and the Wechsler subtest scores and IQs 12 were statistically significant (rs = .45 to .74). The new Wechsler scale appears to be a valid instrument for the 32 children (8–8 to 11–11) who were tested.

Relationships Between Scores on the General Purpose Abbreviated Battery of Stanford-Binet IV, Peabody Picture Vocabulary Test-Revised, Columbia Mental Maturity Scale, and Goodenough-Harris Drawing Test

This study investigated the correlations among the “General Purpose Abbreviated Battery” of the Stanford-Binet IV: Fourth Edition, the Peabody Picture Vocabulary Test-Revised, the Columbia Mental Maturity Scale, and the Goodenough-Harris Drawing Test. A third-grade class of 23 children (11 boys, 12 girls) took all four of the tests, and the intercorrelations of the total scores of the four tests were calculated. The Binet IV and Peabody correlation was statistically significant (p < .01) as was the correlation between Binet IV and Columbia (p < .05). The correlation between Binet IV and Goodenough-Harris was not statistically significant (p > .05).

Relationships between Scores on Stanford-Binet IV and Wechsler Preschool and Primary Scale of Intelligence.

A kindergarten class of 9 boys and 11 girls took the 1986 Stanford-Binet Intelligence Scale (Fourth Edition) and the Wechsler Preschool and Primary Scale of Intelligence. Of 6 correlations of total scores and subtest pairs, only the correlation of total scores was statistically significant (p<.01).

Relationships among scores on the Stanford-Binet IV, Peabody Picture Vocabulary Test-Revised, and Columbia Mental Maturity Scale

This study investigated the correlations among the Stanford-Binet Intelligence Scale (4th Edition), the Peabody Picture Vocabulary Test-Revised, and the Columbia Mental Maturity Scale. A kindergarten class of 21 children (10 boys, 11 girls) took each test, and the intercorrelations of the total scores and the correlation between the Binet IV Vocabulary subtest and the Peabody were calculated. Only the relations between Binet IV and Peabody and between Binet IV Vocabulary and Peabody were found to be statistically reliable.

RELATIONSHIPS BETWEEN SCORES ON WECHSLER PRESCHOOL AND PRIMARY SCALE OF INTELLIGENCE-REVISED AND STANFORD-BINET IV'

The Wechsler Preschool and Primary Scale of Intelligence—Revised and the Stanford Binet-Intelligence Scale: Fourth Edition were given to 51 preschool, kindergarten, first, and second grade students. Twelve of 15 Pearson correlations between Wechsler IQs and composite and area scores of the Stanford-Binet IV were statistically significant. It is apparent that the two tests measure similar, but not identical, concepts.

CORRELATIONS OF SCORES OF MAXIMUM SECURITY INMATES ON WECHSLER ADULT INTELLIGENCE SCALE-REVISED AND PEABODY PICTURE VOCABULARY TEST-REVISED

29 men (15 white, 14 black) who were inmates at a maximum security penitentiary were given the Wechsler Adult Intelligence Scale—Revised and the Peabody Picture Vocabulary Test—Revised on which the full scale IQs correlated .80. This suggests the Peabody would serve as an effective screening test for this population.

Comparison of Kaufman's short form of the McCarthy Scales of Children's Abilities and the Stanford-Binet Intelligence Scales--Fourth Edition.

21 kindergarten children completed the Stanford-Binet-IV (Binet-IV) and the McCarthy Scales of Childrens Abilities. Kaufmans (1977) estimated General Cognitive Index (GCI) was computed from the entire McCarthy scales. There was only one significant difference among the Binet-IV and estimated GCI scores. Abstract/Visual Reasoning was significantly lower than the Kaufman GCI. Correlations of the five Binet-IV Standard Age Scores and the Kaufman GCI ranged from .29 to .67. The correlation between the GCI and the Kaufman estimated GCI was .91.
