We investigated whether anxiety, depression, pain sensitivity, and pain intensity modulated functional connectivity related to DMN nodes, CEN nodes, and insula. Resting-state functional magnetic resonance imaging data were collected from 31 females with FM and 28 age-matched healthy controls. Connectivity was analysed with a region-based connectivity analysis between DMN nodes in ventromedial prefrontal cortex (vmPFC) and posterior cingulate cortex, CEN nodes in the intraparietal sulcus (IPS), and bilateral insula. FM patients displayed significantly higher levels of anxiety and depressive symptoms than controls. The right IPS node of the CEN showed a higher level of connectivity strength with right insula in FM with higher pain intensity compared to controls. More anxiety symptoms in FM correlated with higher levels of connectivity strength between the vmPFC DMN node and right sensorimotor cortex. These findings support the theory of altered insular connectivity in FM and also suggest altered IPS connectivity in FM. Interestingly, no change in insular connectivity with DMN was observed.<\/jats:p>","DOI":"10.3390\/jcm9113560","type":"journal-article","created":{"date-parts":[[2020,11,5]],"date-time":"2020-11-05T09:04:34Z","timestamp":1604567074000},"page":"3560","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Exploration of Functional Connectivity Changes Previously Reported in Fibromyalgia and Their Relation to Psychological Distress and Pain Measures"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3587-3568","authenticated-orcid":false,"given":"Helene","family":"van Ettinger-Veenstra","sequence":"first","affiliation":[{"name":"Department of Clinical Neuroscience, Karolinska Institute, S-171 77 Stockholm, Sweden"},{"name":"Center for Medical Image Science and Visualization (CMIV), Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2803-3069","authenticated-orcid":false,"given":"Rebecca","family":"Boehme","sequence":"additional","affiliation":[{"name":"Center for Medical Image Science and Visualization (CMIV), Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"},{"name":"Center for Social and Affective Neuroscience (CSAN), Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6396-5104","authenticated-orcid":false,"given":"Bijar","family":"Ghafouri","sequence":"additional","affiliation":[{"name":"Pain and Rehabilitation Centre, and Department of Health, Medicine and Caring Sciences, Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00e5kan","family":"Olausson","sequence":"additional","affiliation":[{"name":"Center for Medical Image Science and Visualization (CMIV), Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"},{"name":"Center for Social and Affective Neuroscience (CSAN), Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rikard K.","family":"Wicksell","sequence":"additional","affiliation":[{"name":"Department of Clinical Neuroscience, Karolinska Institute, S-171 77 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4316-1264","authenticated-orcid":false,"given":"Bj\u00f6rn","family":"Gerdle","sequence":"additional","affiliation":[{"name":"Center for Medical Image Science and Visualization (CMIV), Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"},{"name":"Pain and Rehabilitation Centre, and Department of Health, Medicine and Caring Sciences, Link\u00f6ping University, S-581 85 Link\u00f6ping, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"160","DOI":"10.1002\/art.1780330203","article-title":"The American College of Rheumatology 1990 Criteria for the Classification of Fibromyalgia","volume":"33","author":"Wolfe","year":"1990","journal-title":"Arthritis Rheum."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/j.semarthrit.2016.08.012","article-title":"2016 Revisions to the 2010\/2011 fibromyalgia diagnostic criteria","volume":"46","author":"Wolfe","year":"2016","journal-title":"Semin.
