This RCT study investigates the effects of a self-management program on clinical status indexes of COPD patients.


In this study, 50 COPD patients referred to the respiratory clinic participated.


Patients were randomly assigned to control and intervention groups. The control group received standard care, and the intervention group received standard care plus the self-management program. Patients were assessed by spirometry, Modified Borg scale, and 6-minute walking test at the baseline and the end of 12-weeks. Paired t-test, independent t-test, and chi-square were used to analyze variables.


No significant difference was noted in the spirometry indexes mean in the two groups; however, significant differences were noted in dyspnea and exercise tolerance at the end.

Conclusion/Clinical Relevance:

Using the 5A model can lead to increased exercise tolerance and decreased dyspnea in COPD patients. Therefore, this self-management program is recommended as an effective way to improve their functional status.
