Doing less but getting more: Improving forced-choice measures with Item Response Theory [PDF]
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
