Determination of the Parameters of Six Multiple Choice Tests of Mashhad University of Medical Sciences (1389-90) based on Item-Response Theory (IRT)
Background: According to the industrialization of countries and development of societies, tests and methods are required to employ people in industries and organizations and make the best selection in getting workforce. Interviews, Written tests , and multiple choice tests are common methods used in employing people. Among these methods , multiple choice tests is the easiest one because of th...
متن کاملThe Relationship between Parameters from Two Polytomous Item Response Theory Models
RESPONSE THEORY MODELS Various polytomous IRT models parameterize the probability of response categories differently from each other. For example, the graded response model (GRM) (Samejima, 1969) is based on the cumulative log-odds principle, whereas the generalized partial credit model (GPCM) (Muraki, 1992) is based on the adjacent log-odds principle. It is widely known that these two polytomo...
متن کاملFitting Item Response Theory Models to Two Personality Inventories: Issues and Insights.
The present study compared the fit of several IRT models to two personality assessment instruments. Data from 13,059 individuals responding to the US-English version of the Fifth Edition of the Sixteen Personality Factor Questionnaire (16PF) and 1,770 individuals responding to Goldberg's 50 item Big Five Personality measure were analyzed. Various issues pertaining to the fit of the IRT models t...
متن کاملRandomized Item Response Theory Models
The randomized response (RR) technique is often used to obtain answers on sensitive questions. A new method is developed to measure latent variables using the RR technique because direct questioning leads to biased results. Within the RR technique is the probability of the true response modeled by an item response theory (IRT) model. The RR technique links the observed item response with the tr...
متن کاملA comparison of discriminant logistic regression and Item Response Theory Likelihood-Ratio Tests for Differential Item Functioning (IRTLRDIF) in polytomous short tests.
BACKGROUND Short scales are typically used in the social, behavioural and health sciences. This is relevant since test length can influence whether items showing DIF are correctly flagged. This paper compares the relative effectiveness of discriminant logistic regression (DLR) and IRTLRDIF for detecting DIF in polytomous short tests. METHOD A simulation study was designed. Test length, sample...
