Join our online Club
Online discussion groups (i.e. the Clubs) are an easily accessible and effective way to learn from each other.
COSMIN Clubs are for researchers involved in clinimetric studies, COSMIN systematic reviews or interested in developing, evaluating and selecting measuring instruments. The Club offers you the opportunity to present your (ongoing) work, receive and give feedback and ask any questions your may have.

Measurement in Medicine
Measurement in MedicinePractical guide for developing and evaluating measurement instruments
We published the book on Measurement in Medicine, based on the COSMIN methodology. It provides practical advice, underpinned by theoretical principles, on developing and evaluating measurement instruments in all fields of medicine.
This is a perfect course book for students and a perfect companion for professionals/researchers in the medical and health sciences who care about the quality and meaning of the measurements they perform.
