The role of social media for patients with temporomandibular disorders: A content analysis of Reddit.

Abstract

Social media is frequently used to discuss health topics among users. Reddit is a popular social media platform particularly suit for discussion about chronic illness because of its anonymity that allow users to express uninhibited feelings. Temporomandibular disorders (TMD) represent a chronic painful disorder which has been rarely studied in terms of social media discussion. By exploring how Reddit is used to discuss about TMD, we aim to raise awareness to clinicians involved in TMD management about the online discussion on this topic. A quantitative content analysis was performed on a pool of most relevant threads and comments about the topic "TMJ" on Reddit. Following a codebook, two independent coders assessed multiple clinically relevant variables. A third subject resolved eventual discrepancies. Reddit is mostly used by subjects with TMD asking for advice to other users about symptoms and treatment modalities. The most discussed causes of TMD were bruxism and dental occlusion, and the most discussed treatments were oral appliance therapy and complementary and alternative treatments. The most favourable opinions about treatment modalities were for self-care and behavioural therapy while the least favourable opinions were for surgery and irreversible dental treatments. Reddit represents an excellent data-mining platform to retrieve valuable information about health-related discussion by the community. Our findings suggest an overall alignment of such discussion with evidence-based science about TMD; however, to further increase this trend, we encourage healthcare provider to take an active role in the digital spread of scientifically valid information.
