Methodological Expectations of Campbell Collaboration Intervention Reviews (MECCIR)

Download the latest MECCIR conduct standards and MECCIR reporting standards from our journal website.

Methodological Expectations of Campbell Collaboration Intervention Reviews (MECCIR) are standards for the conduct and reporting of Campbell systematic reviews of intervention effects. These standards are based on and adapted from Cochrane MECIR conduct and reporting standards and we gratefully acknowledge the original work of the Cochrane MECIR project team: Rachel Churchill, Julian Higgins, Jackie Chandler, David Tovey and Toby Lasserson.

Each MECCIR conduct or reporting standard is designated as either "mandatory", "highly desirable" or "optional". There may be variation between or (across reviews) within topic-based Campbell Coordinating Groups (CGs) in the emphasis placed by Editors on compliance with (and/or the need for authors to provide justification for non-compliance with) "highly desirable" MECCIR conduct and reporting standards ("highly desirable" means that this should generally be done but that there are justifiable exceptions). The "optional" designation is reserved for those standards that are done at the authors’ discretion.

To publish a review in the Campbell Systematic Reviews journal, there are three documents that must be submitted in succession by the review team: (a) a title registration form, (b) a protocol for the proposed review, and (c) the completed review. The protocol is a detailed plan that explains the rationale and background for the review, its objectives, and the methods (procedures) to be used for conducting the review. It is therefore important for prospective authors to familiarise themselves with MECCIR standards that will apply in the course of conducting and reporting a review (i.e. post-protocol) at least at the protocol development stage and, ideally, at the title registration stage, and to ensure that the protocol describes methods that comply with at least mandatory standards.

MECCIR conduct and reporting standards are living documents that will be updated on an ongoing basis. Proposals for major or minor revisions to MECCIR conduct or reporting standards may be submitted by a CG's Co-chair to the Co-chairs of the Campbell Methods CG at any time. Authors or users of Campbell reviews of intervention effects should channel any proposals for revisions to MECCIR conduct or reporting standards through their affiliated CG.

Please direct enquiries or queries regarding MECCIR conduct or reporting standards to the Managing Editor of your affiliated Campbell CG.
