Abstract

Purpose
This study investigates the mediating effects of self-care competence on the relationship between uncertainty and quality of life in stroke patients.
Methods
This study adopts a descriptive research approach using 158 patients diagnosed with ischemic or hemorrhagic stroke through brain Magnetic Resonance Imaging (MRI) or Computed Tomography (CT). The data collection period was from May 20, 2020 to September 29, 2020. The data were analyzed using descriptive statistics, Pearson’s correlation coefficient analysis, and a three-step regression analysis using Baron and Kenny’s method for mediation.
Results
The mean scores for uncertainty, self-care competence, and quality of life were 3.07±0.49, 3.66±1.07, and 3.54±0.93, respectively. Self-care competence was found to completely mediate the relationship between uncertainty and quality of life (z=-5.31, p<.001), and its explanatory power was 77.2%.
Conclusion
To improve the quality of life among stoke patients in uncertain situations, it is necessary to improve their self-care competence and develop step-by-step and differentiated self-care competence enhancement programs through multidisciplinary collaboration.
