团队人格组成、团队过程对团队有效性的作用

Team Personality Composition and Team Effectiveness: The Mediating Effects of Team Process

由于团队对组织的重要性，团队有效性的研究倍受关注。通过对342个大学生短期团队完成决策任务的研究，旨在探讨团队人格组成与团队中间过程对团队有效性的作用机制。研究以自陈式问卷调查收集数据，采用层次回归与结构方程模型进行统计分析。研究结果表明：团队过程变量（协作、信念、凝聚力）在团队人格组成（外向性、宜人性、神经质）与团队有效性之间起中介作用，横断研究的I-P-O整体模型得到验证。

As organizations increasing usage of teams， the success of team management is vital to the survival and development of organizations. Therefore， the research on team effectiveness has gained more and more attention lately. Based on previous literature， our current study examined the mediating role of team process through which team members’ personality composition contributes to team effectiveness. Input-Process-Output (I-P-O) model was used as a key theoretical framework. With a transverse approach， this study supported the I-P-O model.Our 1341 participants were all from a large Southeastern University of China. They formed 342 short-term self-managing teams. Greenland Survival was used as the team task. The data were self-reported. Both hierarchical regression and structural equation modeling (SEM) were applied to test the hypotheses.The relationship between team personality composition and team effectiveness was mediated by team process in this transverse study， namely cooperation， cohesion and potency.This study contributes to the literature of team research in two ways. First， a large sample made it possible to analyze the mediating effect of team process between team personality composition and team effectiveness at the team level， which may enlighten team-level research in the future. Second， the I-P-O model was supported by SEM in our study， the first time with a Chinese sample. In a word， our findings showed that team personality composition significantly explains team processes and team outputs， which calls for more attention to personality factors in future team research and team management practice.
