Absolute alpha power was calculated using the fast Fourier transform and by averaging within the power spectra of the alpha band (8\u201313\u2005Hz). The participants rated their subjective sleep quality on a scale of 1\u201310 for the past 7 nights. Bayesian linear mixed models evaluated the unique and moderating effects of sleep quality, group (abstinent, non-abstinent), eye condition (open, closed), and electrode location on resting-state alpha power.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Results indicated that subjective sleep quality did not differ between groups and that alpha power was decreased in the non-abstinent group. However, in the abstinent group only, better sleep quality was associated with decreased alpha power. There was no evidence of a relationship between sleep and alpha power in the non-abstinent group. This effect was similar across eye conditions, but was stronger at the right, posterior, and superior electrodes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These results could indicate a return to homeostasis during early abstinence or that those currently using might not get as much benefit from sleep, highlighting resting-state alpha power as a potential target for addressing sleep-related issues.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15500594261450039","type":"journal-article","created":{"date-parts":[[2026,5,12]],"date-time":"2026-05-12T04:20:47Z","timestamp":1778559647000},"page":"341-350","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["The Effects of Abstinence status and Sleep Quality on Resting State Alpha Power in Cocaine Use Disorder"],"prefix":"10.1177","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0910-3095","authenticated-orcid":false,"given":"Heather E.","family":"Webber","sequence":"first","affiliation":[{"name":"University of Texas Health Science Center at Houston"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3770-8144","authenticated-orcid":false,"given":"Danielle A.","family":"Kessler","sequence":"additional","affiliation":[{"name":"University of Texas Health Science Center at Houston"},{"name":"Department of Surgery, University of Colorado, 12631 East 17th Avenue, Room: 6111, Aurora, CO, 80045, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3561-4614","authenticated-orcid":false,"given":"Joy M.","family":"Schmitz","sequence":"additional","affiliation":[{"name":"University of Texas Health Science Center at Houston"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3447-6539","authenticated-orcid":false,"given":"Scott D.","family":"Lane","sequence":"additional","affiliation":[{"name":"University of Texas Health Science Center at Houston"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2822-3754","authenticated-orcid":false,"given":"Robert","family":"Suchting","sequence":"additional","affiliation":[{"name":"University of Texas Health Science Center at Houston"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,5,11]]},"reference":[{"issue":"9","key":"e_1_3_2_2_2","first-page":"38","article-title":"Sleep disorders in substance abusers: How common are they?","volume":"6","author":"Mahfoud Y","year":"2009","unstructured":"Mahfoud Y, Talih F, Streem D, Budur K.
