Surgeons' personalities have been described as different from those of the general population, but this was based on small descriptive studies limited by the choice of evaluation instrument. Furthermore, although the importance of the human factor in team performance has been recognized, the effect of personality traits on technical performance is unknown. This study aimed to compare surgical residents' personality traits with those of the general population and to evaluate whether an association exists between their personality traits and technical performance using a virtual reality (VR) laparoscopy simulator.
In this study, 95 participants (54 residents with basic, 29 with intermediate laparoscopic experience, and 12 students) underwent personality assessment using the NEO-Five Factor Inventory and performed five VR tasks of the Lap Mentor™ basic tasks module. The residents' personality traits were compared with those of the general population, and the association between VR performance and personality traits was investigated.
Surgical residents showed personality traits different from those of the general population, demonstrating lower neuroticism, higher extraversion and conscientiousness, and male residents showed greater openness. In the multivariable analysis, adjusted for gender and surgical experience, none of the personality traits was found to be an independent predictor of technical performance.
Surgical residents present distinct personality traits that differ from those of the general population. These traits were not found to be associated with technical performance in a virtual environment. The traits may, however, play an important role in team performance, which in turn is highly relevant for optimal surgical performance.
外科医生的性格与普通人群不同，但这是基于小样本描述性研究，评估工具的选择有限。此外，尽管团队绩效中的人为因素的重要性已得到认可，但个性特征对技术绩效的影响尚不清楚。本研究旨在使用虚拟现实（VR）腹腔镜模拟器比较外科住院医师的人格特质与普通人群的人格特质，并评估其人格特质与技术绩效之间是否存在关联。
本研究共纳入 95 名参与者（54 名基础腹腔镜经验、29 名中级腹腔镜经验和 12 名学生），采用 NEO-五因素量表进行人格评估，并完成 Lap Mentor™基本任务模块的 5 个 VR 任务。将住院医师的人格特质与普通人群进行比较，并探讨 VR 表现与人格特质之间的关系。
外科住院医师表现出与普通人群不同的人格特质，表现为较低的神经质、较高的外向性和尽责性，男性住院医师表现出更高的开放性。在多变量分析中，调整性别和手术经验后，没有发现任何人格特质是技术表现的独立预测因素。
外科住院医师具有独特的人格特质，与普通人群不同。这些特征在虚拟环境中与技术表现无关。然而，这些特征可能在团队绩效中发挥重要作用，而团队绩效对于最佳手术表现至关重要。
