Weijters, Bert; Geuens, Maggie; Schillewaert, Niels – Applied Psychological Measurement, 2010
The severity of bias in respondents' self-reports due to acquiescence response style (ARS) and extreme response style (ERS) depends strongly on how consistent these response styles are over the course of a questionnaire. In the literature, different alternative hypotheses on response style (in)consistency circulate. Therefore, nine alternative…

Maij-de Meij, Annette M.; Kelderman, Henk; van der Flier, Henk – Applied Psychological Measurement, 2008
Mixture item response theory (IRT) models aid the interpretation of response behavior on personality tests and may provide possibilities for improving prediction. Heterogeneity in the population is modeled by identifying homogeneous subgroups that conform to different measurement models. In this study, mixture IRT models were applied to the…

Pastor, Dena A.; Beretvas, S. Natasha – Applied Psychological Measurement, 2006
The present study illustrates an extension of Kamata's (2001) restricted form of the hierarchical generalized linear model that provides a multilevel longitudinal Rasch measurement model appropriate for use with polytomous responses. This extension can be used to assess average and interindividual change in the latent trait of interest,…

Rost, Jurgen; Carstensen, Claus H. – Applied Psychological Measurement, 2002
Developed a multidimensional Rasch model that is a multidimensional extension of item component models and determined relations to existing multidimensional item response theory models. Applied the model to a questionnaire on students' interest in physics to demonstrate that model parameters can be estimated even when 17 latent dimensions are to…

Hol, A. Michiel; Vorst, Harrie C. M.; Mellenbergh, Gideon J. – Applied Psychological Measurement, 2007
In a randomized experiment (n = 515), a computerized and a computerized adaptive test (CAT) are compared. The item pool consists of 24 polytomous motivation items. Although items are carefully selected, calibration data show that Samejima's graded response model did not fit the data optimally. A simulation study is done to assess possible…

Rost, Jurgen – Applied Psychological Measurement, 1988
A generalized Rasch model is presented for measuring attitudes; it is based on the concepts of Thurstone's method of successive intervals. Benefits of the model are illustrated with a study of students' (N=4,035 fifth through ninth graders) interest in physics. (SLD)
