Sleep researchers’ rankings of sleep journals

The impact factor is used to rank the quality of scientific journals but has been criticised for a number of reasons. The aim of the study was to investigate sleep researchers’ perceptions of sleep journals to determine whether subjective rankings of journals were in line with the journals’ impact factors. Clarivate's Journal Citation Reports website was used to identify journals containing the words ‘sleep’ or ‘dream’ in the titles with an impact factor since 2018, resulting in 12 journals. A survey including questions about how the respondent would rank these journals (e.g., three most prestigious journals) was developed. A total of 122 sleep researchers completed the survey. Sleep, Sleep Medicine Reviews and Journal of Sleep Research were ranked as the three most prestigious sleep journals, in line with the impact factors of the journals. For the rest of the journals, the subjective rankings and impact factors did not correspond as much.
