Factors influencing self-management in Parkinson's disease: A cross-sectional study.

This study aimed to identify factors influencing self-management in patients with Parkinson's disease (PD) based on social cognitive theory. A cross-sectional design was used; data were collected at three tertiary medical centers in Korea from a convenience sample of 356 PD patients. Higher self-management scores were associated with higher education level, having a religion, and higher family income. Self-management score was positively correlated with activities of daily living, self-efficacy, and social support, and negatively correlated with non-motor symptoms. Hierarchical regression analysis revealed that demographic factors and non-motor symptoms explained 26.2% of the variance in self-management in PD. The explanatory power increased by 7.5% when self-efficacy was added, and by 6.7% when social support was added. Assessment of self-management in patients with PD should consider self-efficacy and social support, along with demographic factors and non-motor symptoms. Self-management programs that reflect these factors may be useful for improving self-management in PD patients.
