Developing and Measuring IS Scales Using Item Response Theory
Information Systems (IS) research frequently uses survey data to measure the interplay between technological systems and human beings. Researchers have developed sophisticated procedures to build and validate multi-item scales that measure latent constructs. Most studies use classical test theory (CTT), which suffers from several theoretical shortcomings. We discuss these problems and present i...
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 کاملPsychometric Properties of State Level Subjective Vitality Scale based on classical test theory and Item-response theory
The purpose of the present study was to investigate the factor structure and Item-Response parameters of State Level of Subjective Vitality Scale. The research design was correlational, and the statistical population consisted of students of the Shahid Beheshti University of Tehran. Sample group including 240 students were selected through multi-stage sampling and completed Subjective Vitality ...
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 کاملSelection the best Method of Equating Using Anchor-Test Design in Item Response Theory
Explaining the problem. The equating process is used to compare the scores of the two different tests with the same theme. The goal of this research is finding the best method of equating data using Logistic model. Method. we are using the data of Ph.D. test in Statistic major for two consecutive years 92 and 93. For analyzing, we are specifically using the tests of Statistics major ...
