Purpose: This study examined the influence of nursing students’ competencies in assessment, communication, clinical judgment, and patient safety on evidence-based practice (EBP) competency through simulation training. Methods: Data were collected from in December 11 in 2023 to January 30 in 2024, using a self-report questionnaire. The final participants were 230 nursing students in two universities. Multiple regression, t-test, ANOVA were used for data analysis. Results: The competencies of nursing students who participated in simulation training significantly influenced their EBP competency. The most influential factor on nursing students’ competency of EBP was Clinical Judgment, followed by Communication. Assessment and Patient safety competencies did not have a statistically significant impact on EBP competency. Conclusion: It is crucial for nurses to implement EBP to provide high-quality nursing and advance nursing as a science. However, since EBP competency is difficult to acquire in a short period, education on EBP is necessary from nursing school. Simulation training is considered an effective means to enhance nursing students' competency in EBP. Our study suggests incorporating elements that strengthen competencies in clinical judgment and communication when establishing a simulationbased training program to enhance the EBP competency of nursing students.

Purpose: This study was conducted to provide simulation training on evidence-based practical training and to examine its effects. Method: Data were collected from 83 students at C University, between October 1, 2018 and December 31, 2018. This training was conducted over a 5-week period. Data were analyzed using descriptive statistics, the Friedman test, the Wilcoxon signedrank test, and Repeated Measure ANOVA, all after the normality test. Results: There was a significant difference between the two groups in evidence-based practice beliefs, competence, nursing profession perspective, critical thinking tendencies, and problem-solving ability (p<.001). More specifically, there was a greater improvement in evidence-based practice knowledge, critical thinking tendency, and problem-solving ability than in the existing simulation exercise. Conclusion: Being effective in enhancing the ability to provide evidence-based practice beliefs, competencies, nursing profession perspectives, and, especially in evidence-based practice knowledge, critical thinking tendencies, and problem-solving skills, it is necessary to link evidence-based education and existing simulation training.
