Learning Objective 1: The learner will be able to understand how self-efficacy influence COPD patients exercise behavior.

Learning Objective 2: The learner will be able to know The change of heart rate variability of COPD patients before and after exercise.

Purpose: Chronic Pulmonary Obstructive Disease (COPD) is an in- curable and high prevalence disease. Government paid 1.3 billion dollars for this population yearly in Taiwan. Besides the physical distress, COPD will cause patients’ psychological distress such as depression and anxiety. Pulmonary rehabilitation and regular exercise have proved the benefits for improving the dyspnea perception and exercise tolerance in COPD patients. However, most of COPD patients couldn’t maintain a regular exercise after pulmonary rehabilitation program. Therefore it’s important to explore key factor that might affect COPD patients’ confidence in maintaining regular exercise. This research is a cross-sectional designed to explore the correlations between Exercise Self-regulatory Efficacy(Ex-SRE), exercise behavior, psychophysiological status (perceived dyspnea, exercise tolerance and the change of heart rate variability before and after exercise). 

Methods: This study will use a convenience sampling and plan to recruit 82 subjects from Ambulatory Department of a Medical Center in northern Taiwan. Recruited Subjects will self-report in Ex-SRE Scale. In addition, the 6 minutes walking distance, HRV and perception of dyspnea before and after walking distance test will be measured in these subjects. Those results of this study will be analyzed by Pearson's correlation coefficient, independent sample t test, liner regression, and multiple regression with the aid of the software package SPSS 18.0.

Results: The research is ongoing.


The results of this proposed study will provide more information for healthcare professionals to understand the key point for COPD patients to maintain regular exercise. And then on the basis of this study, health care professionals can develop an intervention to facilitate the maintenance of regular exercise in COPD patients and further decrease the health care cost.
