Knowledge considered essential for patients with RA was identified through a series of Delphi rounds among rheumatologists, health professionals (HPs), patients, and then reformulated to construct the knowledge questionnaire. Cross-sectional multicenter validation was performed in 12 rheumatology departments to assess internal validity (Kuder-Richardson coefficient), external validity, acceptability, reproducibility (Lin's concordance correlation coefficient) and sensitivity to change (difference in total score before and after patient education sessions). Associations between patient variables and knowledge levels were evaluated.
