Impact factor rankings for sleep research journals between 2005 and 2018

Impact factors and ranking lists of research journals are very often used to judge our career achievements and progression by employers and granting bodies. However, a comprehensive list for the interdisciplinary field of sleep research does not currently exist because our journals tend to be placed into discipline‐specific lists that do not cope well with our historic interdisciplinarity, which embraces many core disciplines. We aimed to build a ranking list specifically for sleep research journals based on the journal impact factor and the google scholar H₅ indices. We then searched for all sleep journals given an impact factor by Thomson Reuters from 2005 to 2018 and all journals given a current H₅ index by Google Scholar. We provide a ranking list specifically for sleep journals that might be useful for researchers to cite when providing context in their applications for employment, promotion and funding.
