Background: Individuals with tinnitus are highly heterogeneous in terms of etiology, manifestation of symptoms, and coping’s mechanisms. Most of these patients are likely to seek hearing health information and social support online via various websites or social media platforms. Indeed, information is easily accessible online. In the absence of evidence-based care, patients with similar symptoms regroup, share experiences, and exchange tips. The present study examines such discussions around tinnitus in Reddit free-texts posts.
Methods: The study uses a cross-sectional design. 130,000 posts were extracted from Reddit’s application programming interface. The 101,000 unique posts were analyzed using automated NLP techniques: hierarchical cluster analysis; unsupervised Machine Learning –Latent Dirichlet Allocation (LDA) — algorithm; and supervised sentiment analysis. After identifying the main topics in the corpus and assessing their sentiment scores, sub-themes are probed in selected topics with LDAs. Reddit users’ interactions are used to measure topics’ cooccurrence in messages and threads.
Results: The cluster and LDA analyses both result in a 16-topic solution with comparable clusters. The sentiment analysis shows heterogeneity among different factors. LDAs ran, e.g., on the Temporo-Mandibular Joint (TMJ) topic, highlights three distinctive sub-themes: teeth and jars; neck and back stress; and muscular and neuralgic pains. Finally, themes overlap emerges from their cooccurrence as suggested by the users’ activity. For instance, the TMJ topic appeared to be often discussed along with the Music Volume topic.
Conclusion: The study maps topics discussed on social media, some not explored in the literature (e.g., supplements, personal timeline). It also investigates topics interconnection in spontaneous discussions. The findings enrich the understanding of patients’ interplay with their conditions and inform the development of appropriate patient-centered strategies to support individuals with tinnitus.
