Forty-four emotionally disturbed and 112 elementary school children were administered the Children's Dysfunctional Cognition Scale (CDC) for purposes of standardizing the instrument. Results indicate that the CDC is reliable and valid. The scale differentiates between normal and disturbed populations and is highly correlated with teacher's ratings…

Special education tests evaluated by M. Thurlow and J. Ysseldyke with regard to technical adequacy were reevaluated using the same criteria. There was disagreement of 11 of the 30 tests used in both evaluations, demonstrating that current test standards are vague enough that experts disagree. (Author/CL)

A paradoxical phenomenon of decreases in reliability as the number of elements averaged over increases is shown to be possible in multifacet reliability procedures (intraclass correlations or generalizability coefficients). Conditions governing this phenomenon are presented along with implications and cautions. (Author)

Reviews the Kaufman Assessment Battery for Children, an individually administered test of intelligence and achievement. Finds it to be of high overall quality. (FL)

The Pre-Reading-Screening Procedures and the Slingerland Screening Tests for Identifying Children with Specific Language Disability were administered to 1021 grade one to six students. Results indicated that reliability and validity coefficients were acceptable and that educational programing decisions could confidently be based on the test…

This study was performed to resolve the question of comparability of manual dexterity scores obtained on wooden and plastic versions of the USES pegboard. Currently authorized equipment, either plastic or wooden, may be used with the confidence that scores are not affected by the type of equipment used. (Author)

In most selection validation research, only the upper and lower tails of the criterion distribution are used, often yielding misleading or incorrect results. Provides formulas and tables which enable the researcher to account more accurately for the distribution of criterion within the middle range of population. (Author/RW)

A direct proof is given for the generalized Spearman-Brown formula for any real multiple of test length. (Author)

Testing showed the dynamometer to be a sufficiently accurate instrument for recording force-time and force-displacement curves. (GW)

This paper discusses the results of a study comparing the psychometric qualities of two forms of a survey, one administered in paper-and-pencil format and the other administered in Web format. The survey addressed the topic of college course anxiety and was used to survey a sample of undergraduate students (n=36). The psychometric qualities…

This study compared the effectiveness of the recently-developed Early Screening Profiles (ESP) with the Kaufman Assessment Battery for Children (K-ABC), two screening tests designed to measure the cognitive, language, motor, and social development of preschool children. The tests were administered in counterbalanced order to a sample of 29…

Undifferentiating response sets, defined as "overuse" of any category of a Likert scale, were identified using a combination of simple criteria, such as whether a single-category response set involved more than four items, and statistical criteria based on D. Andrich's (1978) measurement model for Likert scales (the Rating Scale model). Data were…

The purpose of the study was to compare reliability estimates for a test composed of stimulus-dependent testlets as derived from item scores, testlet scores, and under the univariate generalizability theory and multivariate generalizability theory designs, as well as to determine the influence of the number of testlets and the number of items per…
