Learning Objective 1: The learner will be able to identify the level and the related factors of self-efficacy in patients with COPD.
Learning Objective 2: The learner will be able to discuss the methods or direction for effective nursing interventions concerns of enhancing the self-efficacy in patients with COPD.
The purpose of this study was to identify the level and affecting factors of self-efficacy in patients with chronic obstructive pulmonary disease (COPD) in South Korea.
l Methods
The study participants were 245 patients with COPD at 6 general hospitals in South Korea. The data collection was conducted from March 1 to November 31 of 2010 by self-reported questionnaire. Self-efficacy of COPD patients was measured by the COPD Self-Efficacy Scale (CSES) developed by Wigal and Creer (1991). Collected data were analyzed by SPSS WIN 18.0 program using percentages, means, t-test, ANOVA, Pearson correlation coefficients, and multiple regression.
l Results
The mean score for CSES was 113.13±27.37. The factors predicting self-efficacy of the patients with COPD were gender (r=-.118, p=.032), educational level (r=.161, p=.006), periods since diagnosed as COPD (r=-.214, p<.001), level of dyspnea (r=-.484, p<.001), FEV1 % predicted (r=.152, p=.009), level of problem oriented coping (r=.153, p=.008), level of affective oriented coping (r=-.171, p=.004), life satisfaction (r=.294, p<.001), and perceived social support (r=.280, p<.001), and these factors explained 31.6% of variance for self-efficacy in COPD patients. Self-efficacy was significantly predicted by level of dyspnea (β=-.429), life satisfaction (β=.235), periods since diagnosed as COPD (β=-.139), total monthly family income (β=-.170), and educational level (β=.158).
l Conclusion
The findings of this study provide baseline data that is helpful to developing the nursing interventions to enhance self-efficacy in patients with COPD. To improve self-efficacy of patients with COPD, health professionals should focus on the predictors identified in this study.
