Summary The term ‘oral parafunctional behaviours’ encompasses behaviours that are different from those required for, or associated with, physiological functional needs such as mastication, communication, swallowing or breathing. Previous reports have associated waking‐state oral parafunctional behaviours with biopsychosocial characteristics such as female gender, presence of psychological symptoms, intensity of pain and pain‐related temporomandibular disorders (TMD) diagnosis. However, the findings have been inconsistent, possibly due to methodological limitations and differences. In the present investigation, we aim to determine whether any association is present between waking‐state oral parafunctional behaviours and biopsychosocial characteristics. All participants were investigated using a set of standardised and validated self‐reporting questionnaires and diagnostic criteria for temporomandibular disorders (DC/TMD) examination protocol for clinical characterisation. Univariate analysis found that self‐reported waking‐state oral parafunctional behaviours were statistically significantly associated with presence of anxiety, depression and physical symptoms, pain intensity and TMD diagnosis. However, forward model multiple linear regression analysis indicated that only self‐reported presence of physical and depression symptoms could explain statistically significant portions of the variance in self‐reported waking‐state oral parafunctional behaviours.
