Résumé

The recent Flare-OA questionnaire measuring flare in knee and hip osteoarthritis (OA) (19 items in 5 domains, numerical rating scale) showed good psychometric properties along with classical test theory. This study aimed to determine its scaling properties by Rasch analysis and to present evidence for a refined scalable version.
