In 1989, THE JOURNAL instituted new requirements that all authors sign statements of authorship responsibility and financial disclosure,1 in addition to transfer of copyright. We are now receiving an increasing number of manuscripts with authorship attributed to a group. These include multicenter clinical trials, institutional reports, and statements from various councils and collaborative groups.
JAMA has permitted authorship to be attributed to a group, as long as all members of that group meet full criteria for authorship1,2 and sign a statement that each has "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."3 The members of such groups have usually been listed in a box on the first or last page of the article or in the acknowledgment at the end of
