A part-form methodology was used to study the effect of varying degrees of multidimensionality on the consistency of pass/fail classification decisions obtained from simulated unidimensional item response theory (IRT) based licensure examinations. A control on the degree of form multidimensionality permitted an assessment throughout the range of…

The aims of the present study were threefold: (1) to test for the equivalency of an hierarchical three-factor structure of the Beck Depression Inventory (BDI) across English and French versions for non-clinical adolescents; (2) given evidence of poor model fit, to validate the factorial structure of the BDI French version across three independent…

This paper explores the effectiveness of the Mantel-Haenszel (MH) statistic in detecting differentially functioning test items when the internal criterion is varied. Using a data set from the 1982 statewide administration of a 150-item life skills examination (the New Mexico High School Proficiency Examination), a randomly selected sample of 1,000…

A commonly accepted rule for developing equated examinations using the common-items non-equivalent groups (CINEG) design is that items common to the two examinations being equated should be identical. The CINEG design calls for two groups of examinees to respond to a set of common items that is included in two examinations. In practice, this rule…

This study examined the relationship between the Collegiate Assessment of Academic Proficiency Critical Thinking test (CAAP-CT) and the College Outcome Measures Program objective test battery (COMP). Focus was on determining: (1) the relationship between the CAAP-CT and the COMP process-oriented subscores and the freshman to sophomore gains in…

A nominal response model-based computerized adaptive testing procedure (nominal CAT) was implemented using simulated data. Ability estimates from the nominal CAT were compared to those from a CAT based upon the three-parameter logistic model (3PL CAT). Furthermore, estimates from both CAT procedures were compared with the known true abilities used…

This study compares the McCarthy Scales of Children's Abilities (MSCA) and the Kaufman Assessment Battery for Children (K-ABC) profiles of successful and unsuccessful preschoolers with learning disabilities. Subjects, 40 preschool students, were tested at the beginning and at the end of the preschool year and were placed into repeating or…

A statistical method has been developed for nested incomplete samples in a longitudinal study in which part of the sample has dropped out in such a way that the data have a nested pattern. A procedure which performed well in a Monte Carlo experiment was extended to a two-factor incomplete design with repeated measures on one factor. Methods…

The Group Assessment of Logical Thinking (GALT) instrument has been widely used to gather cross-cultural data regarding the acquisition of logical thinking skills in adolescent children. This study of West German adolescents using the instrument adds further comparative data regarding the development of logical thinking skills. Additional data…

Forty three-option multiple choice (MC) statements on a midterm examination were converted to 120 true-false (TF) statements, identical in content. Test forms (MC and TF) were randomly administered to 50 undergraduates, to investigate the validity and internal consistency reliability of the two forms. A Kuder-Richardson formula 20 reliability was…

This study compares the results of three psychometric tests which were administered to middle class children in first, third and fifth grades in Puerto Rico and to a similar sample in New York State. The tests used were: (1) the Matching Familiar Figures (MFF) Test, (2) the Intellectual Achievement Responsibility (IAR) Scale, and (3) a paired…

Several methods for estimating item response theory scores for multiple subtests were compared. These methods included two multidimensional item response theory models: a bi-factor model where each subtest was a composite score based on the primary trait measured by the set of tests and a secondary trait measured by the individual subtest, and a…

Whether a developmental dissociation exists between direct and indirect tests of picture memory was studied using 29 second graders and 29 sixth graders given a 1-day retention interval. Sixth graders performed better than second graders when memory was tested directly, but the performance of both groups was comparable when memory was tested…

To investigate the psychometric feasibility of replacing a paper-and-pencil licensing examination with a computer-administered test, a validity study was conducted. The computer-administered test (Cadm) was a common set of items for all test takers, distinct from computerized adaptive testing, in which test takers receive items appropriate to…

According to item response theory (IRT), examinee ability estimation is independent of the particular set of test items administered from a calibrated pool. Although the most popular application of this feature of IRT is computerized adaptive (CA) testing, a recently proposed alternative is self-adapted (SA) testing, in which examinees choose the…
