Objective: To assess the 24-month effects of a pulmonary rehabilitation program (PRP) on anxiety, depression, quality of life and physical performance of COPD patients. Methods: Thirty patients with COPD (mean age, 60.8 ± 10 years; 70% males) participated in a 12-week PRP, which included 24 physical exercise sessions, 24 respiratory rehabilitation sessions, 12 psychotherapy sessions and 3 educational sessions. All patients were evaluated at baseline (pre-PRP), at the end of the treatment (post-PRP) and two years later (current) by means of four instruments: the Beck Anxiety Inventory; the Beck Depression Inventory; Saint George's Respiratory Questionnaire; and the six-minute walk test (6MWT). Results: The comparison between the pre-PRP and post-PRP values revealed a significant decrease in the levels of anxiety (pre-PRP: 10.7 ± 6.3; post-PRP: 5.5 ± 4.4; p = 0.0005) and depression (pre-PRP: 11.7 ± 6.8; post-PRP: 6.0 ± 5.8; p = 0.001), as well as significant improvements in the distance covered on the 6MWT (pre-PRP: 428.6 ± 75.0 m; post-PRP: 474.9 ± 86.3 m; p = 0.03) and the quality of life index (pre-PRP: 51.0 ± 15.9; post-PRP: 34.7 ± 15.1; p = 0.0001). There were no statistically significant differences between the post-PRP and current evaluation values. Conclusions: The benefits provided by the PRP in terms of the indices of anxiety, depression and quality of life, as well as the improved 6MWT performance, persisted throughout the 24-month study period.Keywords: Pulmonary disease, chronic obstructive; Rehabilitation; Exercise; Quality of life; Anxiety; Depression. ResumoObjetivo: Analisar os efeitos, após 24 meses, de um programa de reabilitação pulmonar (PRP) sobre os níveis de ansiedade, depressão, qualidade de vida e desempenho físico em pacientes com DPOC. Métodos: Trinta pacientes com DPOC (idade média, 60,8 ± 10 anos; 70% do sexo masculino) participaram de um PRP com 12 semanas de duração, incluindo 24 sessões de exercício físico, 24 sessões de reeducação respiratória, 12 sessões de psicoterapia e 3 sessões educacionais. Os pacientes foram avaliados na linha de base (pré-PRP), ao término do PRP (pós-PRP) e dois anos mais tarde (momento atual) através de quatro instrumentos: Inventário de Ansiedade de Beck; Inventário de Depressão de Beck; Questionário Respiratório do Hospital Saint George; e teste da caminhada de 6 minutos (TC6). Resultados: A comparação entre o pré-PRP e o pós-PRP revelou uma redução significativa dos níveis de ansiedade (pré-PRP: 10,7 ± 6,3; pós-PRP: 5,5 ± 4,4; p = 0,0005) e de depressão (pré-PRP: 11,7 ± 6,8; pós-PRP: 6,0 ± 5,8; p = 0,001), assim como melhoras na distância percorrida no TC6 (pré-PRP: 428,6 ± 75,0 m; pós-PRP: 474,9 ± 86,3 m; p = 0,03) e no índice de qualidade de vida (pré-PRP: 51,0 ± 15,9; pós-PRP: 34,7 ± 15,1; p = 0,0001). Não houve diferenças estatisticamente significativas entre os resultados do pós-PRP e os do momento atual. Conclusões: Os benefícios obtidos através do PRP sobre os índices de ansiedade, depressão e qualidade de vida, assim como no TC6, persis...

The effect of psychotherapy provided as part of a pulmonary rehabilitation program for the treatment of patients with chronic obstructive pulmonary disease 499The effect of psychotherapy provided as part of a pulmonary rehabilitation program for the treatment of patients with chronic obstructive pulmonary disease* ABSTRACTObjective: To assess the effect of psychotherapy on levels of anxiety and depression, as well as on quality of life and exercise capacity in patients with chronic obstructive pulmonary disease enrolled in a pulmonary rehabilitation program. Methods: A randomized, controlled, blind clinical trial was conducted involving 49 chronic obstructive pulmonary disease patients. Patients were randomized into three groups: those submitted to the complete pulmonary rehabilitation program, which included psychotherapy and an exercise regimen (group 1); those submitted to the program minus physical exercise (group 2); and those submitted to the program minus psychotherapy (group 3). The three groups underwent a 12-week treatment program. All patients were evaluated at baseline and at completion of the pulmonary rehabilitation program through four instruments: The Beck Anxiety Inventory, Beck Depression Inventory and St. George's Respiratory Questionnaire were applied. The distance walked-weight product was also calculated. Results: Statistically significant absolute improvements in exercise capacity were found for groups 1 and 2, although not for group 3 (p = 0.007, p = 0.008 and p = 0.06, respectively). In groups 1 and 2, levels of anxiety and depressions were also significantly reduced (group 1: p = 0.0000 and p < 0.0003; group 2: p = 0.0001 and p = 0.0014), and quality of life was significantly improved (p = 0.0007 and p = 0.002, respectively). Anxiety levels were also reduced in group 3 (p = 0.03), although levels of depression were not, and quality of life was unaffected. Conclusion: Psychotherapy sessions provided as part of a pulmonary rehabilitation program assist patients with chronic obstructive pulmonary disease in coping with disease-related limitations by reducing behavioral symptoms, especially depression, thereby influencing exercise capacity and health-related quality of life.
