The role of coping styles in temporomandibular disorder patients with myalgia
Abstract Background Patients suffering pain related temporomandibular disorders (TMD) exhibit greater levels of psychological distress, environmental stress, somatic symptoms, anxiety, depression, somatic awareness, pain catastrophizing, and pain coping strategies compared to pain-free controls. However, little is known about psychological factors involved in the different TMD types fulfilling DC/TMD criteria. Furthermore, regardless of the severity, the role of general coping strategies and styles in TMD is not yet well understood. The main goal of this study was to investigate anxiety, personality traits, and coping behavior in a group of dentistry students suffering from temporomandibular disorder with myalgia. Methods A total of 102 participants were recruited for this study. Following clinical evaluation, a mylagic TMD group (24 participants) and a control group (25 participants) were formed. Participants were later assessed in anxiety, stress coping strategies, and personality measures. Results The myalgic TMD group presented greater levels of trait anxiety and neuroticism in comparison to the control group. In addition, participants with myalgia showed higher levels of avoidance coping. Conclusions Avoidance coping strategies are generally considered maladaptive, as they seem to increase perceived stress, a robust predictor of TMD. Interventions to reduce stress levels and prevent maladaptive coping styles, tailored to the needs of myalgic TMD patients, might improve temporomandibular health and prevent the myalgic TMD and its chronification.
