Veterinary medicine sits at an unusual intersection: much of its clinical and applied research is produced by mixed teams of practicing clinicians, laboratory scientists, epidemiologists, and industry-funded collaborators, often working across a caseload rather than a single funded trial. That mix makes authorship disputes a recurring problem in veterinary publishing, and it is why the American Veterinary Medical Association’s (AVMA) journals — the Journal of the American Veterinary Medical Association (JAVMA) and the American Journal of Veterinary Research (AJVR) — spell out authorship criteria explicitly in their instructions for authors rather than leaving the question to convention.
This guide covers what AVMA journals require for someone to be listed as an author, how that maps onto the wider ICMJE four-criteria framework most biomedical journals use, and — the part that generates the most disputes in practice — which common veterinary-research roles do not on their own qualify a contributor for authorship, including funding-only sponsors, referring clinicians who supplied cases, and technicians who collected data without further intellectual involvement.
What AVMA/JAVMA authorship instructions require
AVMA journals’ instructions for authors, published via AVMA Journals (the platform hosting JAVMA and AJVR), set out a four-part authorship test for contributors. Based on the publicly posted instructions for authors, a qualifying author must have:
- Made a substantial contribution to the conception or design of the study, or to acquisition of the data used in the study, or to analysis and interpretation of that data;
- Been involved in drafting the manuscript or revising it critically for important intellectual content;
- The opportunity to approve the submitted manuscript and all subsequent revised versions; and
- Agreed to be accountable for the validity and integrity of the data and results.
All four conditions must be met — satisfying only the first bullet (a data, design, or analysis contribution) without the drafting/revision, approval, and accountability elements does not qualify someone for authorship. This is substantively the same four-part structure used in the ICMJE recommendations, which is unsurprising: AVMA journals, like most biomedical and clinical-science publishers, position their authorship policy within the broader ICMJE-influenced convention rather than inventing an independent standard. Readers should still treat AVMA’s own instructions-for-authors page as the operative source for a given submission, since journal-specific wording and required forms can be updated between ICMJE revisions.
Each author submitting to JAVMA is also required to complete a separate copy of AVMA’s Copyright Assignment Agreement and Authorship Form, and the corresponding author is responsible for ensuring that a completed form is on file for every listed author before publication. That form-based sign-off is a procedural check, not a substitute for meeting the four substantive criteria above — an author can complete the paperwork and still be an inappropriate inclusion if their actual contribution does not meet the test.
What does NOT qualify someone for authorship
The instructions are explicit that individuals who contributed to a study but do not meet all four criteria should not be listed as authors — they belong in the acknowledgments section instead. In veterinary research specifically, several contributor types come up repeatedly as borderline cases:
Funding-only contributors
A funder, sponsor, or grant-awarding body that provided financial support but had no substantive role in study design, data collection, analysis, or manuscript preparation does not qualify for authorship under the AVMA criteria — the same position ICMJE takes. Instead, the funding source is disclosed in the acknowledgments, along with a statement describing (or disclaiming) any role the funder had in study design, data interpretation, manuscript writing, or the decision to submit for publication. This distinction matters more in veterinary medicine than it might in some other fields because a substantial share of clinical veterinary research — particularly pharmaceutical and nutrition studies — is industry-funded, which makes the funding-disclosure statement a routine, closely scrutinized part of the acknowledgments section rather than a formality.
Referring clinicians and case-supply-only contributors
Veterinary case series and retrospective studies frequently draw cases from multiple referring practices or specialty hospitals. A clinician who referred a case, or whose hospital’s caseload was used, but who did not otherwise participate in study design, data analysis, or manuscript drafting/revision, does not meet the authorship bar on that contribution alone. This is a common source of disputes precisely because referring clinicians often feel an ownership stake in “their” patient’s data — the appropriate resolution under the stated criteria is acknowledgment (and, where merited, an invitation to contribute more substantively so the criteria are genuinely met) rather than automatic authorship.
Data-collection-only technical roles
Veterinary technicians, research assistants, or laboratory staff who performed data collection, sample processing, or specific technical procedures (imaging, laboratory assays, animal handling during procedures) without contributing to study design, analysis and interpretation, or manuscript drafting/revision fall into the same category. AVMA’s guidance explicitly names “individuals who provided technical assistance” and “individuals who performed special tests or research” as acknowledgments-section contributors, not authors, unless their role extends into analysis, interpretation, or manuscript preparation.
Statistical consultation without broader involvement
A statistician who ran an analysis at a researcher’s direction, without involvement in study design or interpretation of what the results mean clinically, is a similar borderline case — the same tension covered in more general terms in CASRAI’s guide on biostatistician authorship under ICMJE criteria. AVMA’s instructions specifically list “individuals who provided assistance with the statistical analyses” as an acknowledgments example, reinforcing that statistical execution alone, absent interpretive and drafting involvement, does not clear the bar.
How this compares to ICMJE and general biomedical practice
Researchers moving between veterinary and human-medicine or general biomedical publishing will recognize the AVMA framework immediately — it mirrors the ICMJE’s own four-part test (substantial contribution; drafting or critical revision; final approval; accountability) closely enough that a manuscript prepared to ICMJE authorship standards should generally satisfy AVMA journals’ requirements as well, and vice versa. See CASRAI’s dedicated guide to the ICMJE’s four authorship requirements and the ICMJE vs. COPE comparison for how authorship-qualification criteria (ICMJE’s domain) differ from misconduct-handling and post-publication authorship disputes (more COPE’s domain). The practical implication for veterinary researchers publishing across both veterinary-specific and general biomedical journals is that maintaining a single, ICMJE-consistent internal authorship policy for a research group will typically satisfy both sets of instructions without needing separate rules per venue.
Practical steps for veterinary research teams
- Decide authorship early, against the written criteria — not by seniority or convention. Map each prospective contributor’s actual role against all four AVMA/ICMJE criteria before drafting the byline, rather than defaulting to “everyone who touched the case gets listed.”
- Document funder role explicitly. Even when a sponsor had no editorial role, include the standard disclosure statement in acknowledgments — AVMA journals expect this to be addressed affirmatively, not left silent.
- Distinguish case supply from research participation. If a referring clinician’s involvement is limited to providing a case or caseload, acknowledge rather than list as author, unless their role is expanded to include design, analysis, or manuscript input.
- Use the Copyright Assignment Agreement and Authorship Form as a checkpoint, not a formality. Since AVMA requires each named author to sign a separate copy, use the point of collecting these forms to re-confirm every listed author actually meets all four criteria — not just to collect signatures.
- When in doubt, consult the journal’s current instructions for authors directly. Journal-specific policies are revised periodically; AVMA Journals’ own instructions-for-authors pages for JAVMA and AJVR are the authoritative, current source for a given submission.
Frequently asked questions
Does providing funding automatically exclude someone from authorship in veterinary journals?
Yes, under AVMA’s stated criteria funding alone is not a basis for authorship. A funder who also participates substantively in study design, data interpretation, or manuscript preparation could separately qualify on that basis, but the financial contribution itself is disclosed in acknowledgments, not credited with a byline.
Can a referring veterinarian who supplied case data ever be listed as an author?
Yes, but not on the basis of case supply alone. If the referring clinician also contributes to study design, data analysis or interpretation, or drafting/revising the manuscript, and meets the remaining approval and accountability criteria, they qualify like any other contributor. Case supply without that broader involvement belongs in acknowledgments.
Do AVMA journals use the same authorship standard as ICMJE?
AVMA journals’ instructions for authors set out a four-part test — substantial contribution, drafting/critical revision, approval of the manuscript, and accountability for the work — that closely mirrors the ICMJE’s four-criteria framework used across most biomedical publishing. Always check the specific, current instructions for authors on the journal you are submitting to, since wording and required forms can differ in detail.
What happens to contributors who don’t meet the authorship criteria?
They are named in the acknowledgments section rather than the byline, along with a description of their specific contribution — for example, technical assistance, statistical consultation, or provision of study materials or cases.
Is a signed authorship/copyright form the same thing as meeting the authorship criteria?
No. AVMA requires each listed author to sign a Copyright Assignment Agreement and Authorship Form, but that form documents compliance — it does not itself establish that someone meets the substantive four-part criteria. Research teams should confirm the criteria are met before, not instead of, collecting signatures.
