Summary
Self-efficacy in chronic obstructive pulmonary disease (COPD) patients is predicted by impaired daily activities and disease duration. These factors significantly influence confidence in managing COPD symptoms and behaviors.
Area of Science:
- Pulmonary Medicine
- Rehabilitation Science
- Psychology
Background:
- Chronic obstructive pulmonary disease (COPD) significantly impacts patients' quality of life and ability to perform daily activities.
- Self-efficacy, or the belief in one's ability to succeed in specific situations or accomplish a task, is crucial for managing chronic conditions like COPD.
Purpose of the Study:
- To identify key factors that determine self-efficacy in patients diagnosed with chronic obstructive pulmonary disease (COPD).
- To explore the relationship between clinical measures, psychological factors, and self-efficacy in COPD patients.
Main Methods:
- A cross-sectional study involving 30 male COPD patients and 30 healthy controls.
- Utilized pulmonary function tests, 6-minute walk test (6MWT), dyspnea scales (Borg, MRC), anxiety/depression scales (HADS), Activities of Daily Living Questionnaire (ADL-Q), and COPD Self-Efficacy Scale (CSES).
Main Results:
- COPD patients reported higher depression, dyspnea, and impaired activities of daily living compared to controls.
- Disease duration and ADL-Q scores significantly correlated with all CSES subscales.
- Lung function, 6MWT distance, Borg score, anxiety, and MRC scores showed significant correlations with specific CSES subscales, particularly behavioral risk factors and environmental influences.
- ADL-Q score and disease duration explained 76% of the variance in COPD self-efficacy.
Conclusions:
- Impaired activities of daily living due to respiratory limitations and disease duration are independent predictors of self-efficacy in COPD patients.
- These findings highlight the importance of addressing functional limitations and the patient's experience with the disease duration to enhance self-efficacy and confidence in managing COPD.
