The annual impact factor for the Journal of Clinical Sleep Medicine rose from 3.456 to a new high of 3.586, according to Clarivate, which announced on June 29 the release of the 2020 update to its annual Web of Science Journal Citation Reports. The journal’s 5-year impact factor also rose from 3.855 to 3.952.
The new update is based on 2019 data from more than 12,000 journals in the sciences and social sciences. The impact factor “is a measure of the frequency with which the ‘average article’ in a journal has been cited in a particular year or period,” expressed as a ratio between citations and recent, citable items published. Similarly, the 5-year impact factor is calculated by combining the statistical data available from consecutive years as a ratio between one year of citations and five years of articles.
The Journal of Clinical Sleep Medicine, the official publication of the American Academy of Sleep Medicine, celebrated its 15-year anniversary in 2019. AASM members can contribute to the journal by submitting a manuscript or volunteering to be a manuscript reviewer.
