Illness uncertainty and dysphagia in Chinese oral cancer patients: the mediation effect of catastrophic cognition.

Purpose: Dysphagia, a serious symptom of oral cancer, is also the most common. Further, patients who are more uncertain regarding their illness tend to catastrophize, which may affect their rehabilitation and long-term survival rate. Considering this relationship, this study aimed to investigate the occurrence of dysphagia in Chinese patients with oral cancer and explore the correlation between catastrophic cognition, illness uncertainty, and dysphagia.
