The purpose of the study is to test relationships between self-efficacy, functional status, knowledge and depression in chronic obstructive pulmonary disease (COPD) patients. The conceptual model for the study is primarily derived from Bandura’s self-efficacy theory. The study uses an exploratory, correlational design. Data from 230 patients who visit the pulmonary clinics at four major hospitals in Taipei were collected. Measures included the COPD Self-Efficacy Scale, Pulmonary Functional Status Scale, Beck Depression Inventory, COPD Knowledge Scale, and selected demographic and COPD related variables. Data were analyzed with descriptive and multivariate statistical analyses. Results indicated that controlling for extraneous variables of frequency of hospitalization and perception of disease severity, functional status can still explained a significant amount of variance in depression. However, self-efficacy and knowledge have no significant predictive power in depression. The study findings can be used as basis for developing interventions and to be further testing.
