Purpose: This study aimed to identify the level of safety performance among mental health hospital workers and the factors associated with it. Methods: A cross-sectional survey was conducted with 425 workers (physicians, nurses, allied health professionals, and administrative staff) across 12 mental health hospitals in two cities in South Korea. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficients, and multiple regression analysis with SPSS. Results: The mean safety performance score was 3.90 out of 5. Factors significantly associated with safety performance included safety knowledge (β=.42, p<.001), safety climate (β=.26, p<.001), safety motivation (β=.18, p<.001), and education level (β=.07, p=.021). The model explained 67.3% of the variance in safety performance. Conclusion: Improving safety performance in mental health hospitals requires an integrated approach that enhances workers' safety competencies and cultivates a positive organizational safety climate. These findings can inform the development of tailored patient safety education programs and organizational safety management strategies for mental health hospital settings.
