The Moderating Effect of Type D Personality on the Relationship Between Job Stress and Job Performance in Operating Room Nurses

Purpose : This study aimed to examine the relationship between job stress and job performance among operating room nurses and to investigate whether Type D personality moderates this relationship. Methods : An online survey was conducted with 150 operating room nurses in Korea to examine the moderating effect. Participants completed self-report measures of job stress, job performance, subjective health status, and Type D personality. Hierarchical regression analysis was used to examine the associations among the variables, and the moderating effect of Type D personality was tested using the SPSS PROCESS macro(version 4.2). Results : A significant interaction was found between job stress and Type D personality(β＝-.40, p＝.008), indicating that nurses with Type D personality experienced a stronger negative impact of stress on job performance. For nurses without this personality trait, the association was weaker. Job stress also showed a significant negative effect on job performance( β＝-.25, p＜.001). In addition, nurses who perceived their health as “moderate” had higher performance than those with “poor” health perception(β＝.18, p＝.012). Conclusion : These results highlight the moderating role of Type D personality in the stress-performance relationship. Psychological traits can influence how stress affects work ability, especially in high-pressure environments like operating rooms. Identifying stress-prone personality profiles may help guide tailored interventions. Supportive strategies addressing both stress and personality may enhance performance and promote patient safety. Future research should consider longitudinal designs and explore organizational factors that interact with individual characteristics to impact clinical performance.
