The impact of telephone-delivered cognitive behaviour therapy and befriending on mood disorders in people with chronic obstructive pulmonary disease: A randomized controlled trial.

Cognitive behaviour therapy reduced depression symptoms but not anxiety. Befriending reduced depression symptoms in the short term and anxiety symptoms in both the short term and long term. Further research is needed to demonstrate non-inferiority of telephone delivery compared with other formats, and to understand the impact of befriending which has the potential to be a cost-effective support for people with COPD. Statement of contribution What is already known on this subject? Depression and anxiety are common comorbidities in people with chronic obstructive pulmonary disease. Mood disorders are not commonly routinely treated in people with chronic obstructive pulmonary disease. Telephone-administered CBT has been shown to be as effective as face-to-face CBT in reducing depression and anxiety. What does this study add? Telephone-administered CBT can reduce depression symptoms in people with COPD. Telephone-administered befriending can reduce anxiety and depression symptoms in people with COPD. People with COPD who have mood disorders would prefer to have CBT than befriending.
