Association Between Coping Strategies and Pain-Related Outcomes Among Individuals with Chronic Orofacial Pain.

Abstract

BackgroundChronic orofacial pain is associated with substantial pain-related disability and emotional distress. Understanding the relationship between individuals’ coping strategies and pain-related outcomes is important yet understudied in this population.PurposeTo test the cross-sectional association of three coping strategies (pain catastrophizing, kinesiophobia and mindfulness) to four pain-related outcomes (depression, anxiety, pain intensity, and pain-related disability) among individuals with chronic orofacial pain, after accounting for relevant demographic and clinical variables.MethodsIndividuals (N=303) with heterogeneous chronic orofacial pain (eg, trigeminal neuralgia, other trigeminal neuropathic pain, persistent idiopathic facial pain and other types) completed self-report measures of coping (Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia, and the 15-item Five Facet Mindfulness Questionnaire), pain intensity and pain-related disability (Graded Chronic Pain Scale), and PROMIS measure of anxiety and depression. We conducted 4 two-step hierarchical regressions for each of the four pain-related and emotional outcomes, with the first step including demographic and clinical covariates, and the second step including the three coping variables together.ResultsPain catastrophizing was the only coping variable significantly associated with pain intensity (B=0.362, SE=0.115, p=0.002, 3% variance explained) and pain-related disability (B =0.813, SE=0.162, p<0.001, 7% variance explained). Pain catastrophizing (B=0.231-0.267, SE=0.046-0.051-0.050, p<0.001), kinesiophobia (B=0.201-0.316, SE=0.081-0.084, p<0.001-0.018), and mindfulness (B=0.231–0.306, SE=0.046-0.067, p<0.001) were each independently associated with symptoms of anxiety and depression, with the largest incremental variance added by catastrophizing (5–8%) and mindfulness (5%).ConclusionPain catastrophizing appears to be an important intervention target to improve pain intensity, pain-related disability, anxiety and depression among individuals with chronic orofacial pain. Kinesiophobia and mindfulness may be additional treatment targets for interventions to improve anxiety and depression.
