Responsiveness and minimal important score differences in quality‐of‐life questionnaires: a comparison of the EORTC QLQ‐C30 cancer‐specific questionnaire to the generic utility questionnaires EQ‐5D and 15D in patients with multiple myeloma

Abstract

All three questionnaires showed an acceptable responsiveness in patients who improved. However, the 15D did not respond optimally in patients who deteriorate and cannot be recommended for use in patients with myeloma.
