The effects of surgeons' leadership on team performance are not well understood. The purpose of this study was to examine the simultaneous effects of transformational, passive, abusive supervision and over-controlling leadership behaviors by surgeons on surgical team performance.
Trained observers attended 150 randomly selected operations at a tertiary care teaching hospital. Observers recorded instances of the four leadership behaviors enacted by the surgeon. Postoperatively, team members completed validated questionnaires rating team cohesion and collective efficacy. Multiple regression analyses were computed. Data were analyzed using the complex modeling function in MPlus.
Surgeons' abusive supervision was negatively associated with psychological safety (unstandardized B = -0.352, p < 0.01). Both surgeons' abusive supervision (unstandardized B = -0.237, p < 0.01), and over-controlling leadership (unstandardized B = -0.230, p < 0.05) were negatively associated with collective efficacy.
This study is the first to assess the simultaneous effects of surgeons' positive and negative leadership behaviors on intraoperative team performance. Significant effects only surfaced for negative leadership behaviors; transformational leadership did not positively influence team performance.
外科医生的领导力对团队绩效的影响尚未得到充分理解。本研究的目的是考察外科医生的变革型、消极、辱骂性监督及过度控制型领导行为对手术团队绩效的同时影响。
经过培训的观察员在一家三级护理教学医院随机选取了150台手术进行观察。观察员记录外科医生表现出的四种领导行为的事例。术后，团队成员完成了经过验证的关于团队凝聚力和集体效能的问卷调查。进行了多元回归分析。数据使用MPlus中的复杂建模功能进行分析。
外科医生的辱骂性监督与心理安全感呈负相关（非标准化系数B = -0.352，p < 0.01）。外科医生的辱骂性监督（非标准化系数B = -0.237，p < 0.01）和过度控制型领导（非标准化系数B = -0.230，p < 0.05）均与集体效能呈负相关。
本研究首次评估了外科医生的积极和消极领导行为对术中团队绩效的同时影响。仅消极领导行为产生了显著影响；变革型领导并未对团队绩效产生积极影响。
