We examined the impact of a team leader coaching intervention on episodic team processes (transition, action, interpersonal) and subsequent team performance outcomes within a surgical context. Specifically, we tested whether coaching team leaders (i.e., surgeons) on promoting effective teamwork facilitates team processes and two important outcomes-delays and distractions. Team processes were indexed using detailed observational protocols by subject-matter experts before and during surgeries. We employed an interrupted time series design whereby half of our participants received coaching midway through the longitudinal period and the remaining served as a quasi-control group. Team processes and outcomes were collected from multiple surgeries, per surgeon, both before and after the coaching intervention (N = 223 surgeries total). Results from a multilevel mixed-model (treatment vs. control, over time) structural equation model suggest that teams where the surgeon (team leader) received the coaching intervention exhibited higher-quality team transition processes. Transition processes related positively to subsequent action and interpersonal processes, which in turn yielded improvements in two different surgical team performance outcomes. Theoretical and applied implications are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

团队领导教练干预：调查在外科手术环境中对团队流程和绩效的影响。

我们研究了团队领导教练干预对外科手术背景下的团队过程（过渡、行动、人际关系）和随后的团队绩效结果的影响。具体来说，我们测试了指导团队领导（即外科医生）促进有效团队合作是否有助于团队进程和两个重要的结果——延迟和分心。在手术之前和手术期间，主题专家使用详细的观察协议对团队过程进行了索引。我们采用了一种中断时间序列设计，其中一半的参与者在纵向期间的中途接受了指导，其余的则作为准对照组。团队过程和结果是从每位外科医生的多次手术中收集的，无论是在教练干预之前还是之后（总共 N = 223 次手术）。多级混合模型（治疗与控制，随着时间的推移）结构方程模型的结果表明，外科医生（团队领导）接受教练干预的团队表现出更高质量的团队过渡过程。过渡过程与随后的行动和人际交往过程呈正相关，这反过来又提高了两种不同的手术团队绩效结果。讨论了理论和应用意义。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。这反过来又提高了两个不同的手术团队的绩效结果。讨论了理论和应用意义。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。这反过来又提高了两个不同的手术团队的绩效结果。讨论了理论和应用意义。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
