Guidance for reviewers

A competing interest exists when professional judgment concerning a primary interest (such as patients' welfare or the validity of research) may be influenced by a secondary interest (such as financial gain or personal rivalry). It may arise for the reviewers of a BMJ article when they have a financial interest that may influence-probably without their knowing-their interpretation of an article.

We, the editors of the BMJ, believe that to make the best decision on how to deal with a paper we should know about any such competing interests that reviewers may have. We are not aiming at eradicating competing interests - they are almost inevitable. We will not reject opinions simply because you have a competing interest, but we would like to know about it.

We used to ask authors and reviewers about any competing interests, but we have decided to restrict our request to financial interests. This is largely a tactical move. We hope that it will increase the number of people who disclose competing interests. Our experience, supported by some research data, was that people often did not disclose them.

Please answer the following questions

  1. Have you in the past five years accepted the following from an organisation that may in any way gain or lose financially from the publication of this paper:

    ______  Reimbursement for attending a symposium?

    ______  A fee for speaking?

    ______  A fee for organising education?

    ______  Funds for research?

    ______  Funds for a member of staff?

    ______  Fees for consulting?

  2. Have you in the past five years been employed by an organisation that may in any way gain or lose financially from the publication of this paper?
  3. Do you hold any stocks or shares in an organisation that may in any way gain or lose financially from the publication of this paper?
  4. Have you acted as an expert witness on the subject of your study, review, editorial, or letter?
  5. Do you have any other competing financial interests? If so, please specify.

We are restricting ourselves to asking directly about competing financial interests, but you might want to disclose another sort of competing interest that would embarrass you if it became generally known after publication. The following list gives some examples.

  • A close relationship with, or a strong antipathy to, a person whose interests may be affected by publication of your paper.
  • An academic link or rivalry with somebody whose interests may be affected by publication of your paper.
  • Membership of a political party or special interest group whose interests may be affected by publication of your paper.
  • A deep personal or religious conviction that may have affected what you wrote and that readers should be aware of when reading your paper.

If you want to declare such a competing interest then please add it to your statement.

To learn more about the thinking that has led to this policy please read the editorial Beyond conflict of interest.
