About the Composite Outcomes Working Group
Composite outcomes pose the challenge of being a combination of instruments pulled together into the composite score.
The objectives of the Composite Working Group are to:
1. Reach a common understanding of the concepts and terms used for “composites” at OMERACT
2. Understand key elements in the development and testing of composites
