The Influence of the Leadership Effectiveness of Nursing Supervisor LMX on the Tendency of Nursing Staff to Leave and Abnormal Events under the Five Personality Traits Regulation Field

This study aims to explore the influence mechanism of nursing supervisors' leader-member exchange (LMX) leadership efficacy on nursing staff turnover intention and the incidence of adverse medical events, while examining the moderating role of the Big Five personality traits in this process. A questionnaire survey was conducted among 376 clinical nursing staff at a medical center in southern Taiwan, with data analyzed using SPSS 25.0. Results indicate that nursing supervisors' LMX leadership efficacy exerts a significant negative influence on nursing staff turnover intention; turnover intention fully mediates the relationship between LMX and adverse events; and among the Big Five personality traits, Extraversion and Conscientiousness exert significant negative moderating effects on the relationship between turnover intention and adverse events. This study highlights the crucial role of personality traits in nursing management, providing empirical evidence and managerial insights for healthcare institutions to reduce turnover rates and enhance patient safety through optimized leadership styles and personnel selection strategies.
