Leaders, particularly new leaders, seek to establish high levels of trust, as it has been associated with higher levels of effectiveness and group outcomes. This study is designed to understand how trust changes and develops for leaders in a new role and the implications of that change. Although calls for research on trust over time have been made for the past 2 decades, our knowledge of this phenomenon is still quite limited. The findings indicate that leader and unit performance is a function not only of absolute trust level, but is also affected by the direction and magnitude of change in trust across time periods, with the highest levels of effectiveness being associated with leaders who exhibited an increase in trust from the group over time. The data also suggest that the direction and rate at which trust grew was determined by initial expectations and transformational leadership behaviors.

领导者，尤其是新领导者，寻求建立高度信任，因为它与更高水平的效率和团队成果相关。本研究旨在了解领导者在担任新角色时信任如何变化和发展，以及这种变化的影响。尽管在过去的 20 年里一直在呼吁对信任进行研究，但我们对这种现象的了解仍然非常有限。研究结果表明，领导者和单位的绩效不仅是绝对信任水平的函数，而且还受到跨时间段信任变化的方向和幅度的影响，最高水平的有效性与表现出增加的领导者有关。随着时间的推移，来自团队的信任。
