The present study is a prospective and descriptive research, with the aim to evaluate the compliance behavior to breathing control strategies and related factors in patients with chronic obstructive pulmonary disease (COPD). Data were collected by convenience sampling method from 36 patients with stable COPD at the OPD of chest medicine and respiratory therapy of two major medical centersin Kaohsiung from March 11 to May 17, 1994. The breathing control training program had been demonstrated two times and each patient needed to practice for 3-5 weeks. By using questionnaire, we collect date about modifying factors, the perseived self-efficacy of brething control, the perceived dyspnea level and the perceived benefits and barriers of breathing control strategies. The validity of the quantitative tools was verified by experts and the reliability was investigated by Cronbach's alpha value to measure it internal consistency. These data were analyzed by SAS/PC＋ 6.04.
The result shows that half of the sujbects (18 patients, 50%) can use purse-lip and abdominal breathing methods correctly. They practiced at least 3 times a day with at least 10 minutes per time. After receiving the training once, the two largest benefits they felt were smoother breathing (25 patients, 69.4%) and better energy (19 patients, 52.8%). The two largest barriers they felt when practicing the strategies were incorrect practicign (20 patients, 55.6%) and being not used to the strategies (18 patients, 50.0%). The main factors affecting the compliance behavior to breathing control strategies are perceived self-efficacy of breathing control and smoking state, and perceived benefits of the breathing control strategies are secondary. With statistical adjustment to the perceived benefits of the breathign control strategies, the odds ratio to patients with lower perceived self-efficacy is 7.1 times better than the higher ones (AOR＝7.1%, 95%CI: 1.3-39.7). With statistical adjustment to the perceived self-efficacy, the odds ratio to patients without smoking is 7.0 times of smoking noes (AOR＝7.0%, 95%CI: 1.2-42.4), and the ratio to patients perceiving at least 3 kinds of benefits is 4.6 times of those who perceived lower than 3 kinds of benefits (AOR＝4.6%, 95%CI: 1.0-22.3).
The research suggestions are: 1) The needs of breathing control to patients with COPD should be emphasized. 2) Those who have a score lower than 86 in their perceived self-efficacy of breathing control and those who do not smoke will be chosen for receiving the breathing control training, and 3) The perceived benefits of breathing control strategies will be the basis of evaluating the effect of patients' practice so as to the breathing controls trategies more efficient clinically.
