A cognitive-behavioral model of dyspnea: Qualitative interviews with individuals with advanced lung cancer.

Objectives: Shortness of breath, or dyspnea, is the subjective experience of breathing discomfort and is a common, distressing, and debilitating symptom of lung cancer. There are no efficacious pharmacological treatments, but there is suggestive evidence that cognitive-behavioral treatments could relieve dyspnea. For this, understanding the psychological, behavioral, and social factors that may affect dyspnea severity is critical.
