Effects of cognitive behavioral therapy on anxiety and depression in patients with chronic obstructive pulmonary disease: A meta-analysis and systematic review

Objective Symptoms such as depression and anxiety are common psychiatric symptoms in patients with chronic obstructive pulmonary disease (COPD). Cognitive behavioral therapy (CBT) is still controversial in the treatment of anxiety and depression in patients with COPD. We conducted a meta-analysis and systematic review to evaluate the effect of CBT on anxiety and depression in patients with COPD, with a view to providing some guidance for clinical application. Materials and methods Computer search Web of Science, EMbase, PubMed, Cochrane Library, search time limit from the establishment of the library to August 2019. Collect the randomized controlled trial (RCT) for this topic. Two investigators independently screened the literature according to inclusion and exclusion criteria, extracted the data and assessed the risk of bias in the included studies. Meta-analysis using RevMan5.3 software. Results A total of 10 studies were included in a total of 1278 patients. Meta-analysis shows that CBT can improve depression and anxiety in patients with COPD. Subgroup analysis showed that intervention time >= 8 weeks had significant differences in improving anxiety, while intervention time <8weeks had significant differences in improving depression. Conclusions Cognitive behavioral therapy may possibly relieve depression in COPD patients in a short period of time, and it takes longer to improve anxiety. Therefore, clinical practice can choose the appropriate intervention time according to the patient's psychological condition.
