Study objectives: Multidisciplinary pulmonary rehabilitation has been the most suitable treatment for chronic obstructive pulmonary disease (COPD). This clinical trial studied the prevalence of anxiety and depression and the effect of a pulmonary rehabilitation program on anxiety and depression levels of 46 COPD patients (mean ± SD age, 62 ± 11 years; 34 men and 12 women). Design: The participants underwent a 12-week treatment program: 24 sessions of physical exercise, 24 sessions of physiotherapy, 12 psychological sessions and three educational sessions. All patients were evaluated at baseline and at completion of the rehabilitation program through three instruments: Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and 6-minute walking distance (Tcam6'). Results: Patients demonstrated significant statistical improvements, including reduced anxiety and depression, and increased endurance: BAI 16.4 ± 6.9 vs. 6.8 ± 5.3 (p < 0.001); BDI: 16.9 ± 8.7 vs. 7.5 ± 6.6 (p < 0.001); Tcam6": 335.7 ± 83.4 vs. 441.6 ± 100.8 (p < 0.05). Conclusions: COPD patients presented high prevalence of anxiety and depression levels. The pulmonary rehabilitation program was able to improve patient exercise performance, and to reduce anxiety and depression levels.
