Authorship Policies

This policy ensures that contributors who have made substantive intellectual contributions to an article are given credit and that contributors understand their role in taking responsibility and being accountable for what is published.

We also publish an acknowledgements statement at the end of the paper, detailing those who helped in carrying out the research but that have not been recognized as contributors, and for personal expressions of gratitude.

DMJ credits authors and contributors at the end of the paper, giving details of who did what in planning, conducting, and reporting the work. This should include all author contributors and may include non-author contributors.

Based on The International Committee of Medical Journal Editors (ICMJE) Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals that authorship be based on the following four criteria:

  1.  Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
  2.  Drafting the work or revising it critically for important intellectual content; AND
  3.  Final approval of the version to be published; AND
  4.  Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

In addition to being accountable for the parts of the work they have done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their co-authors.

Submitting authors should provide assurance that all authors included on a paper fulfill the criteria of authorship. We also ask for assurance that there is no one else who fulfills the criteria that has been excluded as an author.

As for the corresponding authors:

The corresponding author is the one individual who takes primary responsibility for communication with the journal during the manuscript submission, peer-review, and publication process. The corresponding author typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and disclosures of relationships and activities are properly completed and reported, although these duties may be delegated to one or more co-authors. The corresponding author should be available throughout the submission and peer-review process to respond to editorial queries in a timely way, and should be available after publication to respond to critiques of the work and cooperate with any requests from the journal for data or additional information should questions about the paper arise after publication. Although the corresponding author has primary responsibility for correspondence with the journal, the ICMJE recommends that editors send copies of all correspondence to all listed authors.


As for non-author contributors:

Contributors who meet fewer than all 4 of the above criteria for authorship should not be listed as authors, but they should be acknowledged. Examples of activities that alone (without other contributions) do not qualify a contributor for authorship are acquisition of funding; general supervision of a research group or general administrative support; and writing assistance, technical editing, language editing, and proofreading. Those whose contributions do not justify authorship may be acknowledged individually or together as a group under a single heading (e.g. "Clinical Investigators" or "Participating Investigators"), and their contributions should be specified (e.g., "served as scientific advisors," "critically reviewed the study proposal," "collected data," "provided and cared for study patients," "participated in writing or technical editing of the manuscript").

Because acknowledgment may imply endorsement by acknowledged individuals of a study’s data and conclusions, editors are advised to require that the corresponding author obtain written permission to be acknowledged from all acknowledged individuals.
