Abstract: Objective: To investigate the mediating effect of emotional regulation self-efficacy on personality traits and anxiety in patients with atrial fibrillation，and to explore the moderating role of psychological flexibility in mediating effect. Methods: 309 patients with atrial fibrillation were investigated with the big five personality inventory，the regulatory emotional self-efficacy scale，the comprehensive assessment of acceptance and commitment therapy processes and the self-rating anxiety scale. Associations between variables were determined by Pearson correlation analysis and tested for mediating as well as moderating effects by PROCESS V3.0. Results: When controlling for gender，the open personality trait had a significant positive predictive effect on anxiety，the self-efficacy of emotion regulation played a partial mediating role in the relationship between the open personality trait and anxiety，and the mediating effect accounted for 71.2% of the total effect; the mediating effect was mediated by the level of psychological flexibility. Conclusion: The open personality trait can influence the development of anxiety in patients with atrial fibrillation by changing the self-efficacy of regulatory emotional. Improving psychological flexibility can strengthen the mediating effect of regulatory emotional self-efficacy on anxiety.
