Differential item functioning between English, German, and Spanish PROMIS® physical function ceiling items
Our findings support the universal applicability of PROMIS Physical Function items across general populations in Argentina, Germany, and the U.S. The sensitivity analyses indicate that the identification of DIF items was robust for different data analytic decisions. Multiverse analysis is a promising approach to address lack of clear cutoffs in DIF identification
Using bookmarking methods with orthopedic clinicians and patients with fractures produces score interpretation labels for patient-reported outcome measures
