Estimating person parameters via item response model and simple sum score in small samples with few polytomous items: A simulation study.
Background: The Item Response Theory (IRT) is becoming increasingly popular for item analysis. Theoretical considerations and simulation studies suggest that parameter estimates will become precise only by utilizing many items in large samples.Method: A simulation study focusing on a single scale wa...
