The Campbell Collaboration's Coordinating Groups are responsible for the production, scientific merit, and usefulness of Campbell systematic reviews.
There are at present seven Coordinating Groups (with two new ones coming):
The respective groups provide editorial services and support to authors of Campbell reviews and build links with users of systematic reviews.
You can get an overview of the different groups and their officers and roles here.
It is possible to apply to create new Coordinating Groups. View the procedure for registering a Campbell Review Group.
If you would like to get involved in the Campbell Collaboration, or if you are interested in writing a systematic review, please contact the appropriate Coordinating Group.
