MECCIR (Methodological Expectations of Campbell Collaboration Intervention Reviews) are standards for the conduct and reporting of Campbell Collaboration 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.
MECCIR conduct and reporting standards are intended for both internal and external audiences for the collaboration. They will provide authors and users of Campbell reviews of intervention effects with clear and transparent expectations of review conduct and reporting and facilitate the editorial process. MECCIR conduct and reporting standards should be read in conjunction with Campbell Collaboration Systematic Reviews: Policies and Guidelines, a document which articulates the policies that pertain to the nature and production of Campbell systematic reviews as approved by the Campbell Collaboration Steering Group.
Each MECCIR conduct or reporting standard is designated as either ‘mandatory’, ‘highly desirable’ or ‘optional’. At its meeting in Belfast (15 June 2014), the Campbell Collaboration Steering Group approved the adoption of MECCIR conduct and reporting standards (v.1.0) for implementation in Campbell reviews of intervention effects, effective from 1 October 2014. This means that all new or updated Campbell reviews of intervention effects that proceed to the full review production stage (i.e. following approval of the protocol) after the implementation date of 1 October 2014 will need to comply with all mandatory MECCIR conduct and reporting standards in order to be signed-off for publication in the Campbell Systematic Reviews monograph series (i.e. if a standard is designated as ‘mandatory’, this means that a new or updated review should not be published unless the standard is met). In addition, authors of Campbell reviews of intervention effects that are already in production on 1 October 2014 will be encouraged (but not required) by their host Campbell Coordinating Group to ensure that their reviews comply with all mandatory standards. The underlying principle is that the Campbell Collaboration will move to full implementation of MECCIR conduct and reporting standards as soon as possible.
There may be legitimate variation between or (across reviews) within topic-based Campbell Coordinating Groups (i.e. Crime and Justice CG, Education CG, International Development CG, Knowledge Translation and Implementation CG, Social Welfare CG) in the relative 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 emphasis placed on compliance with ‘highly desirable’ standards will remain at the discretion of each Campbell Coordinating Group. The ‘optional’ designation is reserved for those standards that are done at the authors’ discretion.
To publish a review in the Campbell Systematic Reviews monograph series, 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 as experience of applying these standards in Campbell reviews of intervention effects accumulates and as methods of systematic reviewing, and methods policies of the Campbell Collaboration, evolve. Details of updates will be disseminated via this webpage and other collaboration-wide channels and version number and date of last update will be indicated on this webpage. Proposals for major or minor revisions to MECCIR conduct or reporting standards may be submitted on behalf of a topic-based Campbell Coordinating Group (i.e. Crime and Justice CG, Education CG, International Development CG, Knowledge Translation and Implementation CG, Social Welfare CG) by a Coordinating Group Co-chair at any time. Proposals for revisions should be specific, supported by a clear rationale and submitted to the Co-chairs of the Campbell Methods Coordinating Group. Therefore, authors or users of Campbell reviews of intervention effects should channel any proposals for major or minor revisions to MECCIR conduct or reporting standards through their affiliated topic-based Campbell Coordinating Group.
Major revisions to MECCIR conduct or reporting standards will require recommendation for approval by the Campbell Methods Coordinating Group and approval by the Campbell Collaboration Steering Group. Minor revisions will require approval by the Campbell Methods Coordinating Group Co-chairs, in consultation with the Methods Editors. Classification of revisions as major or minor will be based on collective judgment of the Campbell Methods Coordinating Group Co-chairs, formed in consultation with the Methods Editors and/or other members of the Campbell Methods Editorial Board. At least every three years from the date of implementation of MECCIR standards (1 October 2014), a nominated representative of the Campbell Methods Coordinating Group will convene an ad hoc working group to review current conduct and reporting standards and produce ‘major update’ versions of these documents. This working group will comprise representatives of each Campbell Coordinating Group.
Please direct enquiries or queries regarding MECCIR conduct or reporting standards to the Managing Editor of your affiliated Campbell Coordinating Group in the first instance.
