In total, 320 TMD patients were involved in the study. The psychological status of each patient was assessed with questionnaires, including the Symptom Checklist\u201090 (SCL\u201090), Epworth Sleeping Scale (ESS), stress questionnaire and Life Orientation Test\u2010Revised (LOT\u2010R). TMD pain, including pain intensity and pain\u2010related disability, was assessed with characteristic pain intensity (CPI) and disability points scales. The associations of psychological and socio\u2010demographic factors with pain intensity and pain\u2010related disability were assessed through logistic regression analyses. Higher pain intensity was significantly associated with more severe anxiety (<jats:italic>P<\/jats:italic> = 0\u00b7004), more severe somatisation (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001), more severe depression (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001), more severe stress (<jats:italic>P<\/jats:italic> = 0\u00b7001) and lower optimism (<jats:italic>P<\/jats:italic> = 0\u00b7025) in univariate regression analyses. However, multiple regression analysis showed that only somatisation was significantly associated with pain intensity (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001). Higher pain\u2010related disability was significantly associated with more severe anxiety (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001), more severe somatisation (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001), more severe depression (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001), more severe stress (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001) and lower optimism (<jats:italic>P<\/jats:italic> = 0\u00b7003) in univariate regression analyses. However, multiple regression analysis showed that only depression was significantly associated with pain\u2010related disability (<jats:italic>P<\/jats:italic> = 0\u00b7003). Among the psychological and socio\u2010demographic factors in this study, somatisation was the best predictor of pain intensity, while depression was the best predictor of pain\u2010related disability.<\/jats:p>","DOI":"10.1111\/joor.12479","type":"journal-article","created":{"date-parts":[[2016,12,30]],"date-time":"2016-12-30T13:36:45Z","timestamp":1483105005000},"page":"187-196","source":"Crossref","is-referenced-by-count":49,"title":["Associations of pain intensity and pain\u2010related disability with psychological and socio\u2010demographic factors in patients with temporomandibular disorders: a cross\u2010sectional study at a specialised dental clinic"],"prefix":"10.1111","volume":"44","author":[{"given":"N.","family":"Su","sequence":"first","affiliation":[{"name":"State Key Laboratory of Oral Disease West China Hospital of Stomatology Sichuan University Chengdu China"},{"name":"Department of Prosthodontics West China Hospital of Stomatology Sichuan University Chengdu China"},{"name":"Department of Social Dentistry Academic Center for Dentistry Amsterdam (ACTA) University of Amsterdam and VU University Amsterdam Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Lobbezoo","sequence":"additional","affiliation":[{"name":"Department of Oral Kinesiology Academic Center for Dentistry Amsterdam (ACTA) University of Amsterdam and VU University Amsterdam MOVE Research Institute Amsterdam Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"van Wijk","sequence":"additional","affiliation":[{"name":"Department of Social Dentistry Academic Center for Dentistry Amsterdam (ACTA) University of Amsterdam and VU University Amsterdam Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.
