Using classical test theory, item response theory, and Rasch measurement theory to evaluate patient-reported outcome measures: a comparison of worked examples.
OBJECTIVE To provide comparisons and a worked example of item- and scale-level evaluations based on three psychometric methods used in patient-reported outcome development-classical test theory (CTT), item response theory (IRT), and Rasch measurement theory (RMT)-in an analysis of the National Eye Institute Visual Functioning Questionnaire (VFQ-25). METHODS Baseline VFQ-25 data from 240 parti...
متن کاملItem response theory and classical test theory: an empirical comparison
Despite theoretical differences between item response theory (IRT) and classical test theory (CTT), there is a lack of empirical knowledge about how, and to what extent, the IRTand CTT-based item and person statistics behave differently. This study empirically examined the behaviors of the item and person statistics derived from these two measurement frameworks. The study focused on two issues:...

متن کاملPsychometric Properties of the Brief Form of Professor-Students Rapport Scale-based on Classical Test Theory and Item-Response Theory
Introduction: In order to improve the quality of the teaching process, it is necessary to review the professor-student rapport. The purpose of the present study was to investigate the factor structure and item-response parameters of Professor-Students Rapport Scale-Brief (PSRS-B). Methods: In a descriptive-correlation study, 497 students from Shahid Beheshti University of Medical Sciences were ...
متن کاملComparison of classical test theory and item response theory in terms of item parameters
There are two currently popular statistical frameworks for addressing measurement problems namely Classical Test Theory (CTT) and Item Response Theory (IRT). This study is aimed empirically to examine the similarities and differences in the parameters estimated using these two frameworks. For this purpose, firstly the model assumptions and the goodness of fit analyses were checked for IRT. The ...
