Studies have shown that personality traits affect cognitive performance; however, little is known about their influence on surgical performance. This study aimed to assess the impact of the Big Five personality traits on medical students' laparoscopic surgical skills.
In this prospective study, medical students' laparoscopic surgical skills were assessed using the Hiroshima University Laparoscopic Surgical Assessment Device (HUESAD). The participants performed the HUESAD tasks 10 times before they underwent training. After completing the simulator training, they performed the tasks 10 times. Thereafter, they answered Big Five personality trait questionnaires (Extraversion, Neuroticism, Openness to experience, Conscientiousness, and Agreeableness).
Academic medical centers.
Forty medical students (10 women) were recruited. The selection criterion was a lack of simulations or clinical experience in laparoscopic procedures.
No significant correlations were found between personality traits and HUESAD assessment scores before training. Laparoscopic surgical skills improved significantly after the training (p < 0.001). The Big Five personality traits were correlated with improved laparoscopic surgical performance after training (r = -0.44, p < 0.05). Moreover, statistically significant positive correlations were observed between Conscientiousness and improvement rates (r = 0.36, p < 0.05).
The results suggest that medical students scoring high on Conscientiousness were more likely to have improved laparoscopic surgical skills, regardless of their initial skills. The ability to predict laparoscopic surgical skills would be useful in designing tailor-made training programs for safe and high-quality operations.
研究表明人格特质会影响认知表现；然而，关于它们对外科手术表现的影响却知之甚少。本研究旨在评估大五人格特质对医学生腹腔镜手术技能的影响。
在这项前瞻性研究中，使用广岛大学腹腔镜手术评估装置（HUESAD）评估医学生的腹腔镜手术技能。参与者在接受培训前进行10次HUESAD任务。完成模拟器训练后，他们再次进行10次任务。此后，他们回答大五人格特质问卷（外向性、神经质、开放性、尽责性和宜人性）。
学术医学中心。
招募了40名医学生（10名女性）。入选标准是缺乏腹腔镜手术的模拟或临床经验。
训练前人格特质与HUESAD评估得分之间未发现显著相关性。训练后腹腔镜手术技能有显著提高（p < 0.001）。训练后大五人格特质与腹腔镜手术表现的改善相关（r = -0.44，p < 0.05）。此外，尽责性与改善率之间观察到统计学上显著的正相关（r = 0.36，p < 0.05）。
结果表明，无论初始技能如何，尽责性得分高的医学生更有可能提高腹腔镜手术技能。预测腹腔镜手术技能的能力将有助于设计量身定制的培训计划，以实现安全和高质量的手术。
