Mokken Scale Analysis for Dichotomous Items Using Marginal Models
Peer reviewed Peer reviewed
Direct linkDirect link
van der Ark, L. Andries; Croon, Marcel A.; Sijtsma, Klaas – Psychometrika, 2008
Scalability coefficients play an important role in Mokken scale analysis. For a set of items, scalability coefficients have been defined for each pair of items, for each individual item, and for the entire scale. Hypothesis testing with respect to these scalability coefficients has not been fully developed. This study introduces marginal modelling…

A Test of the Hypothesis that Cronbach's Alpha Reliability Coefficient Is the Same for Two Tests Administered to the Same Sample.
Peer reviewed Peer reviewed
Feldt, Leonard S. – Psychometrika, 1980
Procedures are developed for testing the hypothesis that Cronbach's alpha reliability coefficient is equal for two tests given to the same subjects. (Author/JKS)

Measurement Error and ANCOVA: Functional and Structural Relationship Approaches.
Peer reviewed Peer reviewed
Raaijmakers, Jeroen G. W.; Pieters, Jo P. M. – Psychometrika, 1987
Functional and structural relationship alternatives to the standard "F"-test for analysis of covariance (ANCOVA) are discussed for cases when the covariate is measured with error. An approximate statistical test based on the functional relationship approach is preferred on the basis of Monte Carlo simulation results. (SLD)
