This study tested whether the factor structure of the Fear of Sleep Inventory-Short Form (FOSI-SF) differed between women with a history of sexual traumas (ST: including sexual assault and other sexual traumas) and women reporting other Non-ST PTEs. Two samples of undergraduate women who endorsed a history of PTEs (n = 339 and n = 318) completed a battery of questionnaires including the FOSI-SF, as well as other psychological and sleep screening measures. We conducted an exploratory factor analysis in Sample 1 and a confirmatory analysis in Sample 2. In the sample of women endorsing a history of ST, but not those with Non-ST PTEs, four latent factors adequately fit the data: vigilance, fear of the dark, fear of nightmares, and vulnerability. This structure was replicated in the second sample that included only women with a history of ST and showed appropriate convergent and discriminant validity with other study measures. This study illustrates that fear of sleep may differ across PTE, and that for those with a history of ST, the fear of nightmares appears to be distinct from other facets of the fear of sleep construct.<\/jats:p>","DOI":"10.3390\/bs15111462","type":"journal-article","created":{"date-parts":[[2025,10,28]],"date-time":"2025-10-28T09:16:07Z","timestamp":1761642967000},"page":"1462","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Fear of Sleep in Undergraduates with a History of Sexual Trauma"],"prefix":"10.3390","volume":"15","author":[{"given":"Julia","family":"Russell","sequence":"first","affiliation":[{"name":"Department of Psychology, University of Kansas, 1415 Jayhawk Boulevard, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Favour","family":"Oloriegbe","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Kansas, 1415 Jayhawk Boulevard, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8467-7726","authenticated-orcid":false,"given":"Garrett Robert","family":"Baber","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Kansas, 1415 Jayhawk Boulevard, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1884-923X","authenticated-orcid":false,"given":"Anna K.","family":"Quesada","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Kansas, 1415 Jayhawk Boulevard, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nancy A.","family":"Hamilton","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Kansas, 1415 Jayhawk Boulevard, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,27]]},"reference":[{"key":"ref_1","unstructured":"Basile, K.
