The All Aspects of Health Literacy Scale (AAHLS), Decisional Conflict Scale (DCS), Social Support Rating Scale (SSRS) and General Self-Efficacy Scale (GSES) were used to evaluate health literacy, decisional conflict, social support and self-efficacy. Path analysis was performed by constructing a structural equation model, and the mediating effect between variables was validated by the bias-corrected nonparametric percentile bootstrap method.Results: Health literacy, social support, and self-efficacy together explained 20.4% of the variance in decisional conflict. (1) Severe decisional conflict group accounted for 82% of overall patients with stable schizophrenia. (2) there were strong and significant negative relationships between decisional conflict and health literacy, social support, self-efficacy and each of their dimensions (r=− 0.14– 0.27, P< 0.01 or P< 0.05). (3) The path analysis showed that health literacy directly affects decisional conflict (β=− 0.282); additionally, health literacy indirectly affects decisional conflict through social support (β=− 0.319), self-efficacy (β=− 0.010) and through the chain mediating effect of social support and self-efficacy (β=− 0.008).Conclusion: Patients with stable schizophrenia have serious decisional conflict in China, and necessary interventions have to be made. This study found that social support and self-efficacy mediate the relationship between health literacy and decisional conflict in patients with stable schizophrenia in China. Healthcare professionals should emphasize health literacy education for patients, and implement pathway-based targeted interventions to improve health literacy, reduce decisional conflict, and promote the recovery of patients with stable schizophrenia.Keywords: stable schizophrenia, decisional conflict, health literacy, mediating role, structural equation model
