We used longitudinal data from 205 members of 53 student teams who competed in a complex business simulation over 10 weeks to test: (1) whether shared leadership and performance were related reciprocally over time; (2) the relative magnitude of those relationships; and (3) whether a shared leadership intervention changes those relationships. We also considered the influence of team members' mean level personality to account for compositional effects. As anticipated, shared leadership and performance were related positively and reciprocally over time. Moreover, the shared leadership to performance relationship grew stronger and positive whereas the performance to shared leadership relationship remained fairly consistent over time. As expected, the intervention positively related to the trajectory of shared leadership. Finally, we did not find evidence for the hypothesized relationships of personality on shared leadership nor the strength of the intervention.

我们使用了来自 53 个学生团队的 205 名成员的纵向数据，这些成员在 10 周内参加了复杂的商业模拟竞赛，以测试：（1）共享领导力和绩效是否随着时间的推移相互关联；(2) 这些关系的相对大小；(3) 共同的领导干预是否会改变这些关系。我们还考虑了团队成员平均水平人格的影响，以解释构成效应。正如预期的那样，随着时间的推移，共享领导力和绩效呈正相关关系。此外，共享领导对绩效的关系变得更加强大和积极，而绩效对共享领导的关系随着时间的推移保持相当一致。正如预期的那样，干预与共享领导的轨迹正相关。最后，
