This study examined whether sleep mediates the relationships of pain severity with psychomotor vigilance and attention in patients with fibromyalgia by analysing 80 patients with fibromyalgia. Cognitive performance, pain severity and sleep parameters were determined using the Psychomotor Vigilance Task, Brief Pain Inventory\u2013Short\u00a0Form and sleep diaries of seven consecutive nights, respectively. The patients\u2019 demographic data were analysed for potential confounding factors. After adjustment for these confounders, a series of regression analyses was performed to examine the mediating role of sleep. The results indicated that higher pain severity was strongly associated with poorer sustained attention and lower sleep quality, the total effects of pain severity on psychomotor vigilance and attention were significant (c path: \u03b2\u00a0=\u00a00.23, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.04), and pain severity was a significant sleep quality predictor (a path: \u03b2\u00a0=\u00a0\u22120.33, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.01). When sleep quality was entered into the regression model (a\u2005\u00d7\u2005b path), the effects of pain severity on psychomotor vigilance and attention became non\u2010significant (c\u2032 path: \u03b2\u00a0=\u00a00.15, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.20) after adjustment of age, indicating a complete mediating effect of sleep quality in the pain severity\u2013cognitive performance relationship. In conclusion, sleep quality mediates the pain severity\u2013cognitive performance relationship: pain affects sleep quality, which in turn impairs sustained attention. Our findings provide further insight into the processes underlying the relationship between pain and poor cognitive function. Improved sleep quality may offset the detrimental effects of pain on sustained attention.<\/jats:p>","DOI":"10.1111\/jsr.12843","type":"journal-article","created":{"date-parts":[[2019,3,28]],"date-time":"2019-03-28T12:37:31Z","timestamp":1553776651000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Subjective
