The study was conducted using a sample of 349 training delegates who completed both an IRT-scored forced-choice and a normative single stimulus version of the questionnaire. Results largely supported the scaling properties, measurements precision and equivalence of the data structures of the two scoring methods.en© 2015 SHL Group Limited, a part of CEB.
