Caroline Barbara Terwee

Caroline Barbara Terwee's indexed work centers on standards for evaluating the measurement properties of health status questionnaires, a line of inquiry anchored by her 2006 proposal of quality criteria for these instruments, which remains her most-cited contribution. Much of her subsequent research operationalizes that framework through the COSMIN guidelines, checklists, and risk-of-bias tools for systematic reviews of patient-reported outcome measures, where she is frequently the senior author, and through content validity evaluation via Delphi consensus. Related work extends this methodology to selecting outcome measurement instruments for Core Outcome Sets and to appraising specific instruments such as pain severity scales in low back pain. Earlier and collaborative contributions include the international consensus study that established a taxonomy and terminology for measurement properties and the original COSMIN checklist for assessing methodological quality, both of which underpin the later guidelines. Her co-authored textbook *Measurement in Medicine* and involvement in the COMET Handbook further reflect this methodological focus. No software, datasets, patents, or grants are indexed beyond her publications. Taken together, the named works trace a sustained effort to standardize how researchers select, evaluate, and report outcome measurement instruments, with Caroline B. Terwee's contributions spanning foundational criteria through practical guidance.
