01Impact factor
Impact factor of Sleep Medicine Research (2026)
The impact factor shown here is the 2-year mean citedness: citations received in a year by the papers Sleep Medicine Research published in the two previous years, divided by the number of those papers. That is the same formula as the Journal Impact Factor, applied to the open citation data of OpenAlex. The journal is not listed in JCR 2024, so it has no official Journal Impact Factor from Clarivate; the value above is how often its recent papers are cited.
Quartile of Sleep Medicine Research
A journal's quartile (Q1 to Q4) is its position within a subject category: Q1 is the top quarter. The official quartiles are published by Clarivate in Journal Citation Reports (by Journal Impact Factor, in Web of Science categories) and by Scimago as the SJR quartile (in Scopus categories). Sleep Medicine Research is not listed in JCR 2024, so it has no JCR quartile. It is indexed in Scopus, so Scimago shows its SJR quartile. ScholarsColab does not show a quartile until it can show the official one; the impact factor and rank above are calculated from open data.

No AI or language model is used. Your words are matched against the titles of 156,503 real published journal papers, by our mentors and by other researchers (shown without names); journals are ranked by how many closely matching papers they published. Indexing comes from the SCIE, SSCI, AHCI, ESCI, Scopus and JCR 2024 lists, matched by journal name; the impact factor is calculated from OpenAlex open data, not the official Clarivate value, and no quartile is shown until the official JCR or SJR quartile can be; review time comes from the dates publishers deposit in Crossref (not every publisher deposits them). Always check a journal’s scope and current indexing before submitting.
