Equating of psychometric scales and tests is frequently required and conducted in educational, behavioral, and clinical research. Construct comparability or equivalence between measuring instruments is a necessary condition for making decisions about linking and equating resulting scores. This article is concerned with a widely applicable method…

This article proposes a new item selection method, namely, the modified maximum global discrimination index (MMGDI) method, for cognitive diagnostic computerized adaptive testing (CD-CAT). The new method captures two aspects of the appeal of an item: (a) the amount of contribution it can make toward adequate coverage of every attribute and (b) the…

The California Psychological Inventory (CPI), the Slosson Intelligence Test (SIT), and the Shipley-Institute of Living Scale (SILS) were administered to undergraduates. The Intellectual Efficiency scale scores were correlated .52 with the SIT scores and .39 with the SILS scores. The SIT and SILS were correlated .49. (Author/GK)

The development of a measure of test anxiety among adolescents, the FRIEDBEN Test Anxiety Scale, is reported. It is a 23-item scale with subscales for Social Derogation, Cognitive Obstruction, and Tenseness. Data regarding replicability and construct validity are reported using responses of 3,858 students in 23 junior high and high schools. (SLD)

Using a factorially complex test on a highly homogeneous population is explored, and a procedure is demonstrated that can statistically justify using a cognitive test on which Cronbach's alpha is low. The example involves 649 accountants (auditors). Results indicate that unbundling test and sample provides justification for using the data. (SLD)
