This study aimed to investigate the mediating effects of social support and self-efficacy in the relationship between health literacy and self-management behaviors among young and middle-aged patients with CHD after PCI. Methods: A cross-sectional study was conducted among 360 CHD patients aged 18– 59 who after PCI within 1 to 3 months. The data were collected from September 2022 to July 2023 in a tertiary hospital in China. The questionnaires were utilized to gather data on demographic characteristics, social support, self-efficacy, health literacy, and self-management behaviors. The serial mediation model was examined via bootstrapping techniques using SPSS PROCESS v.4.3 macros (Model 6). Results: Participants health literacy was associated with self-management behaviors both directly (β=0.334, P< 0.001) and indirectly through social support (β=0.149, P< 0.001) and self-efficacy (β=0.095, P< 0.001). Social support and self-efficacy serially mediated the association between health literacy and self-management behaviors (β=0.226, P< 0.001), with the total indirect effects accounting for 44.3%, these three mediating paths account for 24.8%, 15.8%, and 3.7% of the overall effect, respectively. Conclusion: Health literacy influences self-management behaviors that the study's findings suggest were significant. Social support and self-efficacy act as mediators in the relationship between health literacy and self-management behaviors. Our findings provide helpful guidance for the future development of targeted and effective psychosocial interventions to enhance CHD patients' self-management, ultimately improving prognosis and quality of life.
