Abstract

PURPOSE
This study was done to investigate the correlation among symptom experience, self-efficacy, depression, and medication adherence in patients with chronic obstructive pulmonary disease (COPD).
METHODS
Participants were 100 patients with COPD recruited in one general hospital in Seoul. A structured questionnaire was used to measure the study variables. Data were analyzed using descriptive statistics, t-test, ANOVA, and Spearman correlation coefficient.
RESULTS
Symptom experience and depression were positively correlated (r=.41, p < .001), symptom experience and self-efficacy were negatively correlated (r=-.21, p=.035). Depression was negatively correlated with self-efficacy (r=-.60, p < .001) and medication adherence (r=-.48, p < .001). Self-efficacy and medication adherence were positively correlated(r=.76 p < .001).
CONCLUSION
Findings from this study indicate that depression and self-efficacy are important variables related to medication adherence in patients with chronic obstructive pulmonary disease. Therefore, depression and self-efficacy should be assessed, and customized nursing interventions should be provided in order to increase medication adherence.
