Flare Assessment in Rheumatoid Arthritis (FLARE-RA) is a patient-reported outcome measure (PROM) to evaluate the flare-related symptoms of individuals with Rheumatoid Arthritis (RA) in the last three months. The present study aimed to demonstrate the translation, cultural adaptation and psychometric properties of the Turkish version of the FLARE-RA. A cross-sectional psychometric analysis study was conducted with a total of 80 patients (61 Women, 19 Men; 49.6 ± 15.4 years). Patients filled-out the Global Health Assessment (GHA), Visual Analog Scale (VAS), Disease Activity Score-28 (DAS-28), Rheumatoid Arthritis Quality-of-Life Questionnaire (RAQoL), Health Assessment Questionnaire (HAQ) in addition to the Turkish FLARE-RA. In addition, participants' Erythrocyte Sedimentation Rate (ESR) and C-reactive protein (CRP) were recorded. Thirty patients refilled the FLARE-RA again, one-week later. In the cross-cultural adaptation, translation procedures and pilot study, each item of the Turkish version of the FLARE-RA was found to be comprehensible. The ICC (two-way random-effect, single-measure model) and alpha values of the Turkish FLARE-RA were 0.97 and 0.96, respectively. The MDC
95 values calculated for the FLARE-RA, FLARE-RA-arthritis, and FLARE-RA-symptoms scores were 2.01, 1.60, and 1.18, respectively. FLARE-RA, FLARE-RA-arthritis, and FLARE-RA-symptoms scores were highly correlated with VAS-rest, VAS-activity, DAS-28, RAQoL, and HAQ scores (r > 0.50). On the other hand, scores of FLARE-RA, FLARE-RA-arthritis, and FLARE-RA-symptoms were moderately correlated with the GHA-patient subscale, GHA-clinician subscale, ESR, and duration of morning stiffness (0.35 < r < 0.50). The present study results demonstrated the reliability and validity of the Turkish FLARE-RA. FLARE-RA is a practical tool to assess the flare of RA patients. [ABSTRACT FROM AUTHOR]- Published
