Communication performance of about 900 hearing-impaired adults was weakly related to 3 of the 4 content domains assessed by the Communication Profile for the Hearing Impaired: namely communication environment, communication strategies, and personal adjustment. (Author/DB)

The Woodcock Johnson Psycho-Educational Battery (Revised) is reviewed in regard to its application with learning-disabled (LD) adults. Strengths of the revised test are identified as are concerns about the low representation of LD adults in the normative sample and the complex interpretation process. (DB)

The factor structure of the Kaufman Assessment Battery for Children was evaluated with 169 gifted students, aged 6-10. Results tentatively suggested that the factor solution for gifted students is dissimilar to that for the standardization sample, as subtests designed to assess sequential processing did not all load together, nor did those…

While scales assessing psychological well-being have been used both as criterion measures and as variables of interest in their own right, there has been little attempt to deal with the issue of the time-boundedness of perceived well-being. A study was undertaken to examine the combined factor structure of two measures of well-being, the…

Presents a unified concept of test validity that integrates both the scientific and ethical considerations of test interpretation and use. Argues that the appropriateness, meaningfulness, and usefulness of score-based inferences are inseparable, and that this integration is based on construct validity. (FMW)

Two studies evaluated the 10-question Nylander questionnaire as a screening test for autism among adults in British psychiatric hospitals. Both studies found high inter-rater reliability and no false negatives, but the studies resulted in an unacceptably high rate of false positives. (Contains 3 references.) (DB)

Evaluation of mean score differences between the Stanford-Binet Intelligence Scale (Fourth Edition) and the Wechsler Intelligence Scale for Children (Revised) (WISC-R) for 126 children with academic difficulties found the Stanford-Binet composite score was significantly higher than the WISC-R score at the lower end of the ability continuum but…

This study evaluated the external validity of a measure of IQ subtest variability, the profile variability index (PVI), with a sample of 146 children referred for psychological testing. Correlation of PVIs on each intelligence test with achievement scores and indexes of discrepancy between actual and predicted scholastic achievement found…

This tutorial summarizes some of the widely known limitations of tests of statistical significance and then focuses on extracting measures of variation accounted for as a supplement to significance testing. Two measures of variation accounted for, eta squared and omega squared, are discussed. Computational formulas, computational examples, and…

A recommendation to renorm the Bayley Scales of Infant Development is based on (1) high scores obtained on infants in rural North Carolina (N=305); (2) published means for other samples of infants born in the 1970s; (3) recent age placement revisions of items on the Gesell Developmental Examination. (Author/JW)

The original factor structure of the Aberrant Behavior Checklist was cross-validated with a U.S. sample of 470 persons with moderate to profound mental retardation (27 percent nonambulatory). Results replicated previous findings, suggesting that the original five factors (irritability, lethargy, stereotypic behavior, hyperactivity, and…

A table is provided for determining the frequency of occurrence of Verbal-Performance discrepancies on the Wechsler Intelligence Scale for Children-Revised (WISC-R) in profiles of high Intelligence Quotient children. Warnings are offered regarding the adverse effect of subtest substitution or omission when administering the WISC-R to highly…

This paper proposes that instructional validity (i.e., the extent to which teachers actually teach the skills that are tested) should be part of the test development process. The development of a district-wide ninth-grade math exam for General Mathematics I (GMI) in the Charleston County School District, South Carolina, is used to illustrate how a…

Increasingly neuropsychologists are under pressure, particularly in child custody and personal injury litigation, to justify the validity of the tests upon which their assessments are based. Reviews research on the validity of clinical opinions based on tests and concludes that test scores must be used in conjunction with life history and current…

The issue of interpretation of standard test scores of minorities is discussed. The history of the issue is reviewed. The National Academy of Science's decision to reinterpret the scores of minorities is summarized. (YP)
