Campbell Methods Coordinating Group

The Methods Coordinating Group (CG) supports the production of Campbell reviews and evidence and gap maps by improving the methodology of research synthesis, and disseminating guidelines for state-of-the-art review methods.

Methods Editors provide reviewers, editorial teams and trainers with advice on locating studies, assessing study quality, integrating study outcomes, and interpreting the results.

  • Information retrieval (e.g., literature searching, publication bias)
  • Study coding (e.g., category construction, coder reliability)
  • Judging research quality
  • Effect size estimation
  • Data synthesis (e.g., models of error, missing data)
  • Research design (e.g., random vs. quasi-experimental designs, place-based random assignment)
  • Economic Methods (e.g., incorporating cost data into systematic reviews)
  • Process and implementation (e.g., incorporating implementation data into systematic reviews)
  • Training in research synthesis
  • Qualitative evidence synthesis
