The Swedish driving-license test consists of a theory test and a practical road test. The aim of this paper is to evaluate which Item Response Theory (IRT) model among the one (1PL), two (2PL) and three (3PL) parameter logistic IRT models that is the most suitable to use when evaluating the theory test in the Swedish driving-license test. Further, to compare the chosen IRT model with the indice...
Item response theory (IRT) was used to investigate whether this method could be applied to measure HRD effectiveness. Attention was given to handling missing data, interpretation of IRT-scores, and comparison with a comprehensive model for explaining HRD effectiveness. An acceptable fit was shown. The IRT method provided much information about the performance of HRD programs with respect to com...
Organisation s value chains are part of a wider chain of events – value networks. This paper explores the role of Internet-related technologies (IRT) in improving inter-organisational linkages and information sharing across value networks and the impact it has on the level of product or service delivered to customers. Using case study findings, the paper illustrates how IRT have strengthened an...
objective: this study has used item response theory (irt) to examine the psychometric properties of health-related quality-of-life. method: this investigation is a descriptive- analytic study. subjects were 370 undergraduate students of nursing and midwifery who were selected from tabriz university of medical sciences. all participants were asked to complete the farsi version of whoqol-bref. sa...
conclusions there were significant distinctions in the skin temperature distribution during exercise according to the activity of the area under consideration during exercise, which may be important in the development of physiological models and heat flux analyses for different purposes. results during pre-exercise, all tsk reached a steady-state (p ≤ 0.05), which ensured adequate thermal stabi...
The serial position effect shows that two interrelated cognitive processes underlie immediate recall of a supraspan word list. The current study used item response theory (IRT) methods to determine whether the serial position effect poses a threat to the construct validity of immediate list recall as a measure of verbal episodic memory. Archival data were obtained from a national sample of 4,21...

This lack of awareness extends to the therapeutic tools that effectively reduce or eliminate the problem. Many nonpharmacologic techniques have been proposed...
of the Dissertation Identifying DIF for Latent Classes with the Dirichlet Process by Miles Satori Chen Doctor of Philosophy in Statistics University of California, Los Angeles, 2015 Professor Peter Bentler, Chair In Item Response Theory (IRT), Differential Item Functioning (DIF) occurs when individuals who have the same ability, but belong to different groups, have different probabilities of an...
Psychometrics has recently seen the development of complex measurement models to better represent test and item data. Item Response Theory (IRT), in particular, comprises a set of non-linear latent variable models that appear to have several conceptual and empirical properties that make them more valuable in practice than classical test theory methods. However, IRT-based models typically requir...
