Anxiety symptoms, the mismanagement of negative emotions and the association with self-reported bruxism

The aim of this paper was to assess the relationship between anxiety and the mismanagement of negative emotions in people with bruxism symptoms. A total of 192 participants were included and divided into non-bruxism (n = 64) and bruxism (n = 128) groups. The bruxism group was subdivided into sleep bruxism (n = 26), awake bruxism (n = 52), and combined bruxism (n = 50). A non-experimental and cross-sectional descriptive method was used. The self-reported bruxism questionnaire (SBQ), the Beck Anxiety Inventory (BAI) and Coping Strategies Inventory (CSI) were used. Statistical analysis was performed using structural equation modelling and the goodness of fit figures presented adequate values. Results showed a strong positive association between inadequate coping, anxiety symptoms and self-reported bruxism. The model showed that self-criticism and social withdrawal strategies have a direct effect on affective-cognitive and somatic anxiety symptoms; these symptoms predicted the clinical symptoms of bruxism.
