Background: and purpose: Cognitive behavioural therapy (CBT) has gained increasing attention for the treatment of psychological disorders. This study aims to establish the effectiveness of CBT on psychological and physical outcomes in patients with chronic obstructive pulmonary disease (COPD).
Methods: Two waves of electronic searches of the PubMed, Cochrane library, EMBASE, Web of Science and China National Knowledge Infrastructure databases were conducted. Statistical analyses were performed using Revman Manager 5.3 and Stata 12.0 software.
Results: Sixteen randomized controlled trials were eligible. There were significant improvements in anxiety (SMD = -0.23; 95% CI: -0.42 to -0.04; P = 0.02), depression (SMD = -0.29, 95% CI: -0.40 to -0.19, P < 0.01), quality of life (MD = -5.21; 95% CI: -10.25 to -0.17; P = 0.04), and mean visits to emergency departments in the CBT groups. No statistically significant differences were observed in fatigue (SMD = 0.88, 95% CI: -0.58 to 2.35, P = 0.24), exercise capacity (MD = 28.75, 95% CI: -28.30 to 85.80, P = 0.32), self-efficacy (SMD = 0.15, 95% CI: -0.05 to 0.34, P = 0.14), or sleep quality (MD = 1.21, 95% CI: -0.65 to 3.06, P = 0.20).
Conclusion: This meta-analysis suggests that CBT can serve as a complementary therapy to improve anxiety, depression, and quality of life in COPD patients and deserves more widespread application in clinical practice.
