Construct validity was assessed by testing 6 a priori hypotheses against other OARSI\u2010recommended physical function measures. A self\u2010reported Global Rating of Change scale was used to classify participants as worsened, improved, and stable. Participants who worsened in physical function were excluded from all analyses. Responsiveness and MIC were assessed using multiple anchor\u2010based and distribution\u2010based approaches.
