Abstract
Objectives: This study aims to explore the potential association among cyberchondria, self-reported temporomandibular disorders (TMDs), somatic symptoms and anxiety, and verify the chain mediating effect of somatic symptoms and anxiety between cyberchondria and self-reported TMDs.
Methods: A cross-sectional study was conducted among community dwellers. A total of 531 participants, ranging in age from 18 to 50 years, were included. They all completed self-report measures of demographic information, the quintessential five TMDs symptoms (5Ts), the somatic symptom scale-8 (SSS-8), the 7-item Generalised Anxiety Disorder Questionnaire (GAD-7) and the short-form version of the cyberchondria severity scale (CSS-12). Statistical analyses were conducted using SPSS, Origin 2021 and Mplus.
Results: The CSS-12 score was higher in participants with self-reported TMDs (p < 0.05). Having systemic diseases, a higher education level, somatic symptoms burden, anxiety and a high level of cyberchondria were significantly linked to self-reported TMDs (p < 0.05). Mediation analysis revealed that cyberchondria has a direct effect on self-reported TMDs (β = 0.129; 95% CI 0.026-0.232). Somatic symptoms burden (β = 0.073; 95% CI 0.031-0.115) and anxiety (β = 0.041; 95% CI 0.010-0.071) respectively mediated the association between cyberchondria and self-reported TMDs. Additionally, somatic symptoms burden and anxiety collectively exhibit a chain mediation effect (β = 0.031; 95% CI 0.005-0.058).
Conclusions: Cyberchondria is associated with self-reported TMDs, mediated by somatic symptoms burden and anxiety. Cyberchondria can both directly and indirectly affect self-reported TMDs. Preventing cyberchondria may be beneficial for reducing the somatic symptoms burden and anxiety associated with self-reported TMDs.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
