Objective. This study documents the measurement properties of a brief, self‐administered questionnaire of disease signs and symptoms in patients with rheumatoid arthritis. Methods. The Rapid Assessment of Disease Activity in Rheumatology (RADAR) questionnaire assesses joint pain/tenderness and clinical status. One hundred ninety‐three pairs of RADAR forms were completed by 45 subjects and their assigned clinician evaluators. Results. Subject—clinician agreement (intraclass correlation coefficients [ICC]) for joint pain/tenderness and clinical status ranged from 0.52 to 0.87 ( P = 0.0001), with 83% ≥0.65. The ICC for change in joint scores over 6 months was 0.83 ( P = 0.0001). Conclusion. The 2‐page RADAR questionnaire produces valid estimates of joint count and clinical status that are sensitive to change.
