Physical, psychological and socio-demographic predictors related to patients' self-belief of their temporomandibular disorders' aetiology.

For each category of self-believed aetiology of the TMD complaint, different associations with physical, psychological and socio-demographic predictors were identified. This may suggest that individual phenotypes play a role in the patient's belief in the cause of the TMD complaint. Determination of phenotypic risk factors associated with aetiological self-belief might help clinicians to provide better treatment, including counselling, to their patients.
