Diagnostic tests are typically administered in a multiple-choice (MC) format due to their advantages of objectivity and time efficiency. The MC-deterministic input, noisy "and" gate (DINA) family of models, a representative class of cognitive diagnostic models for MC items, efficiently and parsimoniously estimates the mastery profiles of…

On the occasion of Psychometrika's fiftieth anniversary, the past twenty-five years' developments in mental test theory are reviewed. Psychometrika articles treating topics in test theory are listed in a bibliography. (Author/LMO)

The simple practice effects commonly observed when retaking general cognitive ability tests present a potential paradox. If observed score changes reflect real changes in g, we must revisit our understanding of its stability. Conversely, if observed score changes reflect something other than a true change in the underlying latent construct, this…

The interrelationships among halo and leniency rating errors were examined using simulated rating data. As leniency increased, halo decreased when measured by dimension intercorrelations but increased when measured by standard deviations across dimensions. Implications of these results for the use of the various measures are discussed. (SLD)

Tracing the development of the Otis test series, the author argues that there will be a continuing demand for group-administered general mental ability tests in education. He foresees a need for better ways of relating ability test scores with skills and achievements to make them more educationally useful. (Author/JAZ)

Examines psychometric characteristics of the 100-item Trauma Symptom Inventory (TSI) in a sample of 370 psychiatric inpatients and psychotherapy outpatients. Post hoc multiple regression analyses indicated that client age, sex, inpatient versus outpatient status, childhood sexual and physical abuse, and adult sexual assault were unique predictors…

Examined stability of the Kaufman Assessment Battery for 53 at-risk preschool children. Over 9 months the stability coefficients for the global scales ranged from .78 to .88, and for the subtests from .65 to .79. Concluded that scores display adequate stability, but the Simultaneous scale is less stable than the Sequential or Achievement scales.…

The general ability factor (G), as enunciated by Charles Spearman in the model of cognitive functioning, has been the foundation of psychometric theory and test making practices for 80 years. Through these decades, some psychologists disagreed with this theory, especially Godfrey Thompson and E. L. Thorndike. Nevertheless, various aptitude tests…

Employed two strategies used to test prerequisite relationships among intellectual skills to examine the sequence of three types of subtraction tasks. A psychometric validation strategy yielded results similar to instructional validation strategy. Supports the use of the more efficient psychometric approach for validating large numbers of learning…

This paper discusses cognitive and noncognitive variables, and their relationship with each other, in learning and in educational evaluation. The nature of noncognitive learning environment variables is examined. The following instruments that have been widely used in assessing classroom environment are described: (1) the Learning Environment…

This report summarizes the results of research designed to study the psychometric and technological feasibility of adaptive testing to assess spatial ability. Data was collected from high school students on two types of spatial items: three-dimensional cubes and hidden figure items. The analysis of the three-dimensional cubes focused on the fit of…

Data are summarized in Scheuneman's Score x Group x Response frequency table in order to investigate item bias. The data can arise from two different sampling models: (1) multinomial sampling in which a fixed sample size is used and the responses are cross-classified according to score, group, and response; and (2) product-multinomial sampling in…

The scientific concept of intelligence has been heavily influenced by the technology of measurement. The variables which can be measured have been made the operational definition of intelligence. This approach differs from a deductive approach, in which a theory of cognition in general is used to derive the sorts of measurements that must be taken…
