Author Contributions and CRediT

Articles may include a statement and metadata that describe the activities of each person who contributed to the article. An author contributions statement acknowledges the specific contributions of each person. When an author contributions statement is provided it should be tagged using an <sec> element with attribute @sec-type="author-contributions” within <back>. CRediT (Contributor Roles Taxonomy) is a high-level taxonomy that can be used to describe the activities of each person in producing a scholarly output. When CRediT information is provided by the author(s), the CRediT roles should be tagged using the <role> element within <contrib> as part of the article metadata.

Schematron validation rules related to the CRediT taxonomy are listed at JATS-0048

Author Contributions and Acknowledgements

A statement of author contributions may be included in an article as its own acknowledgements section, or as part of the acknowledgements section, in the back of the article before the references list. This statement should be tagged as a paragraph <p> within a <sec> element with attribute sec-type="author-contributions" within <back>. The title of this section should be “Author Contributions” unless the author contributions statement is included with other acknowledgements in one acknowledgements section.

If a statement of author contributions is present and uses CRediT roles, then the CRediT roles should be tagged as metadata in <role> elements. The CRediT metadata in <role> elements must match the author contributions statement.

Depending on the journal’s policy for authorship, it may not be possible for all contributors to be included in the author list in the <contrib-group> in the article metadata. In this situation, the author contributions statement can list all contributors with their CRediT roles (and optionally with their degree of contribution), while the in the article metadata should include CRediT metadata tagged in <role> elements for the contributors who are the authors of the article.

CRediT role metadata

If CRediT information is provided by the author(s), then the <role> element should be used to tag the CRediT information for each contributor in the <contrib> element. Each <role> element should have the name of the CRediT role tagged as text within the <role> element, and have attributes @vocab, @vocab-identifier, @vocab-term, and @vocab-term-identifier that correspond to the CRediT role.

If the Author Contributions statement describes the contributions of each contributor using the CRediT roles, then this information should be used to tag CRediT metadata in <role> elements for each <contrib> in the article metadata.

The list below shows the <role> element tagging for all 14 CRediT Roles.

Degree of Contribution Optional

It is possible for two or more contributors to have the same CRediT role. When more than one contributor has the same CRediT role, each contributor’s degree of contribution may optionally be specified as “equal”, “lead”, or “supporting”. If a degree of contribution is provided, the <role> element should have a @degree-contribution attribute which contains a value of “equal”, “lead”, or “supporting.”

  • degree-contribution="equal"
  • degree-contribution="lead"
  • degree-contribution="supporting"

Examples

Example 1: Incorrect

This example of an Author Contributions statement (which was published in article https://doi.org/10.1080/23294515.2020.1818877) is incorrect. The problems in this example are:

  • The sec-type="author-contributions” attribute was omitted
  • Some text from a submission form (“Please provide…") was incorrectly included in addition to the actual statement that was provided by the authors.
<sec id="S0006" disp-level="1">
<title>Author contributions</title>
<p>Please provide a brief statement regarding the contributions of the listed authors regarding the conception, design, data collection, and/or drafting of the manuscript. (See the International Committee of Medical Journal Editors’ Uniform Requirements for manuscripts for more information: <ext-link ext-link-type="uri" xlink:href="http://www.icmje.org/ethical_1author.html">http://www.icmje.org/ethical_1author.html</ext-link>.) All authors contributed to the drafting and revisions to this manuscript. Ekaterina Pivovarova and Robert Klitzman were also interviewers and integral to the data collection process.</p>
</sec>

Corrected version:

<sec id="S0006" disp-level="1" sec-type="author-contributions">
<title>Author contributions</title>
<p>All authors contributed to the drafting and revisions to this manuscript. Ekaterina Pivovarova and Robert Klitzman were also interviewers and integral to the data collection process.</p>
</sec>

The @id and @disp-level attributes are optional.
