One of the core problems of scientific research authorship is honorary authorship. It violates the ethical principle of clear and appropriate assignment of scientific research contributions. The prevalence of honorary authorship worldwide is alarmingly high across various research disciplines. As a result, many academic institutions and publishers were trying to explore ways to overcome this unethical research practice. The International Committee of Medical Journal Editors (ICMJE) recommended criteria for authorship as guidance for researchers submitting manuscripts to biomedical Journals. However, despite (...) the ICMJE guidelines, honorary authorship is still significantly present across various health research disciplines. The aim of this study was to explore the perceptions and knowledge of health care researchers towards honorary authorship according to the ICMJE guidelines across different health care fields in Jordan, which to our knowledge was never explored before. Data from an electronic survey that was distributed among researchers working in different healthcare fields across several major universities in Jordan, revealed that most of the respondents were assistant professors working mainly in the schools of Medicine and Pharmacy. The majority of the respondents (65.5%) were not aware of the ICMJE authorship guidelines. And, around 37% reported the inclusion of an honorary author, in which the most common non-authorship task reported by 73% of the respondents was reviewing the manuscript. Our findings emphasize the need for national academic and research institutions to address the issue of authorship in their educational programs and internal policies. (shrink)
