Performed orthogonal and oblique factor analysis using the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample (N=1,880). Analysis of the variance components for each subtest at every age level revealed a substantial proportion of subtests at a wide range of age levels evidenced high or intermediate levels of specific…

Discusses the significance of confidence intervals around IQ scores based on a misleading interpretation of the standard error of measurement terms provided in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) manual. Presents standard error values and a table for determining the abnormality of verbal and performance IQ discrepancies.…

Changes in the full scale reliability of the WISC-R were computed at three age levels when each subtest was omitted by itself. The same procedure was followed with those subtests which independently had the smallest effect in lowering full scale reliability. Cautions were noted concerning the exclusion of subtests. (Author)

Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of .84 and .69, but analysis of redundancies revealed that only 34 percent of the total WISC subtest variance is redundant with the ITPA and 39 percent of the ITPA subtest variance is redundant with the WISC. (Author)

The relationship between the Slosson (1953) Intelligence Test (SIT) and the Wechsler (1949) Intelligence Scale for Children (WISC) was studied to provide information about the SIT's usefulness as a measure of intelligence, for placement purposes and for screening purposes. (NH)

The purpose of the study was to determine whether WPPSI is a valid and reliable instrument for the measurement of the intelligence of children whose scores fall within the upper range as measured by the Stanford-Binet. The results of this study indicated that there was only a moderate relationship between the two. (Author)

Data from the WAIS, WISC, and WPPSI Standardization samples were used to reappraise validity of all short forms of two, three, four, and five subtests. Results were compared with those given by McNemar's formula. The corrected formula gave lower values and selected "best short forms that differed from McNemar's formula. (Author)

The reliability and stability of the Full Scale IQ scores of retarded adolescents and young adults of three Wechsler Scales were measured. (Author)

A SERIES OF STUDIES SOUGHT TO ASCERTAIN (1) INTER- AND INTRA-RATER RELIABILITY FOR THE HARRIS-GOODENOUGH DRAW-A-MAN TEST, (2) DRAW-A-MAN (DAM) VALIDITY, AND DRAW-A-WOMAN (DAW) VALIDITY. THE DRAWINGS OF 72 STUDENTS IN AN UPPER MIDDLE CLASS WERE SCORED INDEPENDENTLY BY TWO SELF-TAUGHT SCORERS, ONE OF WHOM ALSO RESCORED THE TEST A WEEK LATER. THE…
