The Methods Coordinating Group 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.

Methods subgroups

The Methods Group has several subgroups that conduct empirical research and develop guidelines and recommendations for specific components of research synthesis. The subgroups serve as forums for discussion on research models, and provide advice on specific topics of methodology and methods policy. They also provide training and support to reviewers, editors, and those who wish to undertake a systematic review.

Methods subgroups work within the areas of economic methods, equity methods, implementation process, information retrieval, quasi-experimental design studies, statistics methods, and training. Contact information can be found here.

The subgroups have five general functions:

  • To provide advice on methodology and methods policy
  • To provide training and support
  • To conduct empirical research
  • To monitor the quality of Campbell's systematic reviews
  • To serve as a forum for discussion on research models

The subgroups on methods work closely with the methods groups in our sibling organization The Cochrane Collaboration, to ensure that guidance given by the two organizations is similar.

How can we help you?

Are you working on a Campbell systematic review and in need of consultation regarding a specific methodology? The Methods Group can provide advice on the following topics:
  • 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
