Background: The aim of our study was to assess the prevalence of anxiety and depression in the whole chronic obstructive pulmonary disease (COPD) population and in subgroups according to sex and severity classification. A secondary objective was to evaluate the possible differences between patients with and without a significant high level of anxiety, depression, or both, and finally to find out a correlation between psychological aspects, symptoms, functional parameters, and quality of life (QoL).
Methods: Two hundred and two COPD patients were enrolled.
