Abstract

Forced-choice tests, despite being resistant to response biases and showing good operational validities, have psychometric problems if scored traditionally. These questionnaires are generally longer than their normative counterparts, and more cognitively challenging.

Results suggest that the IRT methodology can significantly improve efficiency of existing forced-choice measures so that test takers can do less (complete shorter and easier questionnaire) and test users can get more (bias-resistant instrument of superior psychometric quality).
