About
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 validation of composites
Current Stage in the OMERACT Process
This methods-focused group is applying the OMERACT Filter to composite measures, using the Clinical Disease Activity Index (CDAI) as an example. Their findings will guide how future composites are developed and evaluated.

Looking Ahead
The group is preparing a publication of our findings from OMERACT 2025 and drafting updated guidance on how to put composites through the OMERACT Filter. This will serve as a key methodological resource for groups considering composite outcomes.
