Rationale and Objectives

To analyze the pattern and longitudinal evolution of honorary authorship in major radiology journals.

Materials and Methods

In this Institutional Review Board-approved study, an electronic survey was sent to first authors of original research articles published in the American Journal of Roentgenology, European Radiology, the Journal of Magnetic Resonance Imaging, and Radiology during 2 years (July 2014 through June 2016). Questions addressed the perception of honorary authorship and contributing factors, as well as demographic information. Univariate analysis was performed by using χ2 tests. Multivariable logistic regression models were used to assess independent factors associated with the perception of honorary authorship.

Results

Of 1839 first authors, 315 (17.3%) responded. Of these, 31.4% (97/309) perceived that at least one coauthor did not make sufficient contributions to merit authorship and 54.3% (159/293) stated that one or more coauthors performed only "nonauthor" tasks according to International Committee of Medical Journal Editors criteria. Of eight factors significantly associated with the perception of honorary authorship on univariate analysis, two were retained by the stepwise multivariate model: having someone suggest adding an author and a coauthor performing only a nonauthorship task.

Conclusion

There has been little variation in the perception of honorary authorship among first authors of original research articles in radiology. The suggestion of adding an author and having coauthors performing only nonauthorship tasks are the two most important risk factors for honorary authorship. Our findings indicate that a prolonged course of transformation of current cultural norms is required to decrease honorary authorship.
