The questionnaire method has always been an important research method in psychology. The increasing prevalence of multidimensional trait measures in psychological research has led researchers to use longer questionnaires. However, questionnaires that are too long will inevitably reduce the quality of the completed questionnaires and the efficiency…

This article extends the procedure outlined in the article by Raykov, Marcoulides, and Tong for testing congruence of latent constructs to the setting of binary items and clustering effects. In this widely used setting in contemporary educational and psychological research, the method can be used to examine if two or more homogeneous…

This article describes an approach to test scoring, referred to as "delta scoring" (D-scoring), for tests with dichotomously scored items. The D-scoring uses information from item response theory (IRT) calibration to facilitate computations and interpretations in the context of large-scale assessments. The D-score is computed from the…

This article is concerned with developing a measure of general academic ability (GAA) for high school graduates who apply to colleges, as well as with the identification of optimal weights of the GAA indicators in a linear combination that yields a composite score with maximal reliability and maximal predictive validity, employing the framework of…

For educators seeking to differentiate instruction, cognitive ability tests sampling multiple content domains, including verbal, quantitative, and nonverbal reasoning, provide superior information about student strengths and weaknesses compared with unidimensional reasoning measures. However, these ability tests have not been fully evaluated with…

Examined the factor structure of the Multidimensional Aptitude Battery (MAB) (D. Jackson, 1984) and the overlap between the MAB and the Wechsler Adult Intelligence Scales-Revised (WAIS-R) using a sample of 85 adults. Results show conditions under which the MAB is a suitable alternative to the MAB. The MAB is not suitable when detailed information…

Although some research has examined the factorial nature of the Multidimensional Aptitude Battery (MAB), none has tested hypotheses relevant to both oblique and orthogonal models via confirmatory factor analysis. Thus, in this investigation, a series of models was tested, which compared the model fit of both oblique/higher order models against a…

This study tested the specificity-generality hypothesis regarding moderation of aptitude test validity by job ability requirement differences using 24,482 Air Force enlistees in 37 jobs. Moderating effects due to job differences were not found, and job ability differences did not moderate the relationship between the amount of "g"…

The academic aptitude at the time of admission to college and level of occupation later in life were collected for 619 male college graduates. The statistically significant relationship indicated that the graduates with higher aptitude scores as compared with those with lower scores were more likely to report higher level occupation.

The purpose of this study was to demonstrate a potential difficulty with relying on null models in LISREL confirmatory factor analytic measurement models and to offer several suggestions for dealing with this concern. Using randomly generated factors in a matrix of 46 aptitude tests, it was shown that this approach is unlikely to reject even…

The relationships were examined between the Ball Aptitude Battery (BAB) and the Comprehensive Ability Battery, Differential Aptitude Tests, and General Aptitude Test Battery. Results showed adequate convergent and discriminant validities for all BAB tests except inductive reasoning, which was factorially complex. (Author/GDC)
