Mediating Effect of Shared Decision-Making on the Relationship between Patient Activation and Self-Management in Patients on Hemodialysis: A Cross-Sectional Study
Year: 2025
Type: article
Study design: Observational Study
Abstract: Purpose: This descriptive correlational study aimed to evaluate the impact of patient activation on self-management and explore the mediating role of shared decision-making (SDM) among patients on hemodialysis.Methods: A cohort of 136 participants was recruited from hemodialysis units in Gwangju, South Korea, between August 9 and 22, 2024. Patient activation, self-management, and SDM were assessed using the Patient Activation Measure (PAM-13), the Hemodialysis Self-Management Instrument (HDMI-K), and the 9-item Shared Decision-Making Questionnaire (SDM-Q-9), respectively. Descriptive statistics, Pearson’s correlation analysis, and mediation analysis using the PROCESS macro were conducted to analyze the data. Results: Patient activation, SDM, and self-management were positively correlated with one another. Mediation analysis showed that patient activation significantly predicted both SDM and self-management. SDM also significantly predicted self-management, confirming its partial mediating effect. The final model explained 54.5% of the variance in self-management. The indirect effect of patient activation on self-management through SDM was statistically significant (indirect effect=0.05, 95% confidence interval [CI]=0.02–0.10). The indirect effect of patient activation on self-management through SDM was statistically significant (indirect effect=0.05, 95% CI=0.02–0.10). Conclusion: Patient activation directly and indirectly enhances self-management through SDM, verifying the partial mediating role of SDM. Integrating SDM into nursing interventions is essential for effectively supporting self-management in patients undergoing hemodialysis.
