A chain of lower bound inequalities leading to the greatest lower bound to reliability is established for the internal consistency of a composite of unit-weighted scores (such as a test). Algorithms for obtaining various reliability coefficients are presented. (Author/JKS)

"Test Scoring" provides insight into psychometric procedures as used by a professional testing company or in large-scale projects. The book contains an overview of standard test theory, a discussion of factor analytic theory, and an exploration of special applications and problems. (SLD)

Q-technique factor analysis identifies clusters or factors of people, rather than of variables, and has proven very popular, especially with regard to testing typology theories. The present study investigated the utility of three different protocols for obtaining data for Q-technique studies. These three protocols were: (1) a conventional ipsative…

It is argued that the statements and accusations made by Stephen Jay Gould about the use of factor analysis are incorrect and unjustified and that tests properly designed for the purpose can adequately measure a "general" or "g" factor of intelligence, particularly in view of the developments in testing since "The…

The concept of a behavior domain is a reasonable and essential foundation for psychometric work based on true score theory, the linear model of common factor analysis, and the nonlinear models of item response theory. Investigators applying these models to test data generally treat the true scores or factors or traits as abstractive psychological…

This paper reports on a short version of the Student Jenkins Activity Survey (JAS), a multiple choice questionnaire that measures Type A "coronary-prone" behavior in assessing subjects' A/B types. The primary objective was to determine if the short and long forms of the student JAS represent similar measurement instruments. A secondary…

Tested validity of the Portuguese version of the Social Competence and Behavior Evaluation questionnaire. Found results similar to original French-Canadian instrument in stability, internal consistency, and factorial structure. Found associations between teacher's description of social competence and behavioral difficulties in Brazilian…

Correlational analysis, classical test theory, confirmatory factor analysis, and multilevel Rasch modeling were used to refine a measure of adolescents' exposure to violence (ETV). Interpersonal violence could be distinguished from other potentially traumatic events; it was also possible to distinguish three routes of exposure (victimization,…

The advantages of applying confirmatory factor analysis (CFA) to multitrait-multimethod (MTMM) data are widely recognized. However, because CFA as traditionally applied to MTMM data incorporates single indicators of each scale (i.e., each trait/method combination), important weaknesses are the failure to: (1) correct appropriately for measurement…
