International application of PROMIS ® computerized adaptive tests: US versus country-specific item parameters can be consequential for individual patient scores

Item response theory (IRT) is increasingly used to create item banks as the basis for computerized adaptive testing (CAT) for measuring patient-reported outcomes (PROs) (Cappelleri et al., 2014, Chang, 2007, Edelen and Reeve, 2007, Nguyen et al., 2014, Reeve et al., 2007). With CAT, after a starting item, subsequent items are selected by the computer based on participants ’ responses to previous items (Embretsen and Reise, 2000, Thissen and Wainer, 2001). With CAT, reliable scores can be obtained with only a few relevant questions (Cook et al., 2005).
