Cognitive profile of patients with burning mouth syndrome in the Japanese population.

The present study investigated which cognitive characteristics, including cancer phobia, self-efficacy, pain-related catastrophizing, and anxiety sensitivity, affect burning mouth syndrome (BMS) symptoms in the Japanese population. A total of 46 BMS patients (44 women and 2 men; mean age, 59.98 +/- 9.57 years; range, 30-79 years) completed a battery of questionnaires, including measures of pain severity, oral-related quality of life (QOL), stress-response, pain-related catastrophizing, self-efficacy, anxiety sensitivity, and tongue cancer phobia. The Pain Catastrophizing Scale (PCS), General Self-Efficacy Scale (GSES), and Anxiety Sensitivity Index (ASI) scores in the BMS patients were compared with the scores of Japanese healthy participants (PCS, n = 449; GSES, n = 278; ASI, n = 9603) reported in previous studies. Catastrophizing and anxiety sensitivity were significantly higher in the BMS patients than in the healthy subjects (P < 0.001). In BMS patients, catastrophizing was significantly correlated with pain severity, stress-response, psychological disability, social disability, and handicap. Cancer phobia was significantly correlated with psychological disability and handicap. Since catastrophizing showed a higher correlation with BMS symptoms than cancer phobia, catastrophizing might be a more significant cognitive factor affecting symptoms than cancer phobia in BMS patients in the Japanese population.
