Calibration of the PROMIS physical function item bank in Dutch patients with rheumatoid arthritis.
<h4>Objective</h4>To calibrate the Dutch-Flemish version of the PROMIS physical function (PF) item bank in patients with rheumatoid arthritis (RA) and to evaluate cross-cultural measurement equivalence with US general population and RA data.<h4>Methods</h4>Data were collected...

An incomplete longitudinal anchored design was used where patients completed all 121 items of the item bank over the course of three waves of data collection. Item responses were fit to a generalized partial credit model adapted for longitudinal data and the item parameters were examined for differential item functioning (DIF) across country, age, and sex.<h4>Results</h4>In total, 690 patients participated in the study at time point 1 (T2, N = 489; T3, N = 311).
