The role of depression on quality of life in patients with chronic orofacial pain Lauren McKay (22945659) PUREID: 526301547 Depression quality of life chronic orofacial pain psychology oral-health related quality of life clinical psychology Chronic orofacial pain is pain which occurs in the head, mouth, face and/or oral regions for at least three months. Depression is known to co-occur with chronic orofacial pain, and quality of life is also known to be negatively impacted in those experiencing chronic orofacial pain. Little is known about the nature of the relationship between depression, chronic orofacial pain intensity and quality of life, therefore, the current thesis aimed to explore the role of depression on quality of life in patients with chronic orofacial pain.<br><br> First, a narrative literature review was conducted which explored the relationship between depression and pain intensity and depression and quality of life in chronic orofacial pain patients. Theoretical perspectives through which chronic orofacial pain is understood were presented, whilst clinical implications of the available evidence were considered in relation to existing treatment approaches for depression in chronic orofacial pain. Based on the evidence found, a model of depression co-occurring with chronic orofacial pain was presented to develop a better understanding of the relationship between the variables of depression, chronic orofacial pain intensity and quality of life. Specifically, it suggested that depression may mediate and/or moderate the relationship between chronic orofacial pain intensity and quality of life in chronic orofacial pain patients. <br><br>The empirical paper aimed to explore the relationship between chronic orofacial pain intensity, oral health-related quality of life and emotional states (depression, anxiety, and stress) in an adult clinical population. Specifically, it aimed to explore the combined model of depression by investigating both the mediating and moderating role of depression in the association between chronic orofacial pain intensity and oral health-related quality of life. Findings suggested that depression partially mediated the relationship between chronic orofacial pain intensity and oral-health related quality of life. Clinical and research implications of these findings were discussed. <br><br><i>Thesis is embargoed until 31 December 2026.</i> 2026-10-01T16:46:41Z Text Thesis 10.17034/32638245.v1 https://figshare.com/articles/thesis/The_role_of_depression_on_quality_of_life_in_patients_with_chronic_orofacial_pain/32638245 All Rights Reserved Open Access after 2026-12-31
