Sinharay, Sandip; Puhan, Gautam; Haberman, Shelby J. – Multivariate Behavioral Research, 2010
Diagnostic scores are of increasing interest in educational testing due to their potential remedial and instructional benefit. Naturally, the number of educational tests that report diagnostic scores is on the rise, as are the number of research publications on such scores. This article provides a critical evaluation of diagnostic score reporting…

Raykov, Tenko – Multivariate Behavioral Research, 2007
A method for point and interval estimation of change in criterion validity of multiple-component measuring instruments as a result of revision is outlined. The procedure is developed within the framework of covariance structure modeling, which complements earlier methods for testing change in composite reliability due to addition or deletion of…

Penev, Spiridon; Raykov, Tenko – Multivariate Behavioral Research, 2006
A linear combination of a set of measures is often sought as an overall score summarizing subject performance. The weights in this composite can be selected to maximize its reliability or to maximize its validity, and the optimal choice of weights is in general not the same for these two optimality criteria. We explore several relationships…

Marsh, Herbert W.; Bazeley, Patricia – Multivariate Behavioral Research, 1999
Evaluated external assessor ratings of the quality of the research team and the proposed research for proposals submitted to the Australian Research Council large grants program. Data from 313 evaluations show that the reliability of the assessments varied systematically with the number of assessors and the score considered. Discusses implication…

Rindskopf, David; Rose, Tedd – Multivariate Behavioral Research, 1988
Confirmatory factor analysis was applied to test second- and higher-order factor models in the areas of structure of abilities, allometry, and the separation of specific and error variance estimates. The estimation of validity and reliability, second-order models within factor analysis models, and the concept of discriminability were also studied.…

Marsh, Herbert W.; And Others – Multivariate Behavioral Research, 1992
Results of a reanalysis of previously published data (B. M. Byrne, 1989) support the correlated uniqueness model, diagnostic tests of the validity of confirmatory factor analysis (CFA), multitrait multimethod (MTMM) solutions, inclusion of external validity in MTMM design, and application of factorial invariance to test stability of CFA-MTMM…
