Year 2004
Access date 03.05.2013


In this chapter we provide a basic introduction to IRT modeling (item response theory), including a discussion of the common IRT models used in research, underlying assumptions of these models, and differences between CTT and IRT modeling. The introduction is followed by a demonstration of the information that can be gained by using IRT to evaluate the psychometric properties of a questionnaire.
