Authorship should convey appropriate credit and establish appropriate responsibility for work done and published.1 For many years, JAMA has asked all authors to sign an authorship responsibility statement certifying that they have met the following criteria:
I have participated sufficiently in the conception and design of this work and the analysis of the data (when applicable) as well as the writing of the manuscript, to take public responsibility for it. I believe the manuscript represents valid work. I have reviewed the final version of the manuscript and approve it for publication. Neither this manuscript nor one with substantially similar content under my authorship has been published or is being considered for publication elsewhere, except as described in an attachment. If requested, I shall produce the data upon which the manuscript is based for examination by the editors or their assignees.
We also have signature forms for financial disclosure, copyright
