To develop and validate a cross cultural version of the Arthritis Impact Measurement Scales 2 (AIMS2) to be used by French speaking populations. ⋯ This cross cultural adaptation of AIMS2 in French is valid, reliable, and responsive in patients with RA in whom MTX therapy is instituted. It would permit international comparison studies. This study provides evidence for construct validity and responsiveness of the original version of the AIMS2, not demonstrated previously.
