Author Contributions Statement

ICMJE encourages contributorship policies and notes that some journals request and publish information about each person’s contributions. It separately defines authorship criteria, so a contribution statement should report roles without collapsing contribution and authorship into the same decision.

Quick answer

An author contributions statement identifies who did which parts of a scholarly work. Use the journal’s required contributor taxonomy or wording, and do not treat contribution listing by itself as proof that someone satisfies authorship criteria.

Important caveats

Scope Boundary

["A listed contribution does not by itself establish authorship eligibility; authorship criteria and acknowledgement rules remain separate editorial decisions."]

Further guidance

Content

["Identify contributions using the journal’s required labels, taxonomy or free-text format and make the attribution specific enough to be meaningful."]

Practical Application

List who performed which parts of the work using the journal’s required wording or contributor taxonomy. Keep the contribution statement distinct from authorship qualification: contribution labels document roles, while authorship eligibility still depends on the journal’s authorship criteria.

Purpose

["Use a contributions statement to make individual roles in the work transparent when the journal or publisher requests it."]

Reader Check

Can a reader tell which named contributor performed each stated role, and has the journal’s authorship/disclosure policy been checked separately?

Worked Example

A statement might say that A.B. designed the study, C.D. analyzed the data, and both drafted and revised the manuscript; do not infer from one listed role alone that a person automatically meets every authorship criterion.
