Abstract:

Objective To analyze the influencing factors of health behaviors in stroke patients， and explore the chain mediating effects of self-efficacy and e-health literacy between the perception of stroke recurrence risk and health behaviors in stroke patients， providing a reference for strengthening the health behavior and reducing recurrence risk in stroke patients. Methods 249 stroke patients were selected as the research objects from March to September 2024 in a tertiary hospital in Shanghai， China. Patients were surveyed using General Information Questionnaire， Stroke Recurrence Risk Perception Scale， Stroke Health Behavior Scale（HBS-SP）， Chronic Disease Self-Efficacy Scale （CDSES）， and the e-health Literacy Scale（e-HEALS）. Pearson correlation analysis was used to explore the correlations among various variables， and SPSS 26.0 software macro program Process Model 6 was used to conduct chain mediation model test. Results The scores of Recurrence Risk Perception， HBS-SP， CDSES and e-HEALS of stroke patients were （42.88 ± 6.48） scores， （68.32 ± 14.13） scores， （6.87 ± 1.55） scores and （27.76 ± 6.06） scores， and all the variables were positively correlated （P < 0.01）. The mediating effect model showed that self-efficacy and e-health literacy played a chain mediating role in the recurrence risk perception and health behavior in stroke patients， with an effect size of 0.488， accounting for 37.22% of the total effect. Conclusions The recurrence risk perception and health behavior of stroke patients are both at a moderate level. In the future， we can establish a mobile management platform to provide comprehensive health management for stroke patients. Further exploration of strategies to enhance stroke patients' self-efficacy and channels for online health education could be pursued to improve their health behaviors.
