团队共享心智模型的影响因素与效果

采用两种测量方法对团队共享心智模型的影响因素与影响效果进行探讨。多元回归和层次回归分析的结果表明，团队成员沟通得越好，就越有利于形成共享心智模型；如果团队中存在搭便车的行为越严重，就越不利于形成共享心智模型；共享心智模型有利于团队有效运作，取得好的绩效；有共享心智模型的团队，成员的满意度比较高，群体效能感较高，并且团队成员之间的密切关系会延续到工作之外；共享心智模型在团队运行过程变量和团队有效性之间起到中介作用。

Antecedents and Consequences of Shared Mental Model in Work Teams

The present study is to examine some team process related antecedents of shared mental model and the relationship between shared mental model and team effectiveness. The antecedent variables include communication, free riding, and trust. The consequence variables include group efficacy, performance, satisfaction and friendship of team members. Data were collected from 158 MBA and graduate students, 35 teams in a university in Beijing. Two distinct methods were used to measure shared mental model: one was team members' perceived similarity of their mental models; the other was intra-team consistency on task-specific critical strategies. Results showed that communication was positively related to shared mental model and free riding was negatively related to shared mental model. Shared mental model was positively related to team performance, satisfaction and friendship of team members, and group efficacy. Shared mental model mediated the relationship between team process variables and team effectiveness.
