Effects of Group-Level Fit on Group Conflict and Performance
将人-环境匹配理论从个体层面扩展到群体层面，研究群体层面的目标匹配和能力匹配如何通过影响任务冲突和关系冲突来预测群体绩效，基于96个团队的数据发现只有目标匹配显著影响绩效且完全由冲突中介。
Departing from the prevailing focus of the person–environment (P-E) fit literature on individual-level outcomes, we apply the fit concept to the group level and develop a theoretical framework that elaborates the nomological network involving group-level goal fit and ability fit. Specifically, we propose that the positive affect exhibited by leaders and members is a predictor of group-level goal fit and ability fit. We expect two types of group-level fit to predict group performance by shaping intermediate interactive dynamics among members, such as task and relationship conflict. Our analyses based on 96 work teams with 898 members provide empirical support for most of our hypotheses. Of the two group-level fit constructs, only group-level goal fit exerts a significant effect on group performance, which is completely mediated by task and relationship conflict. These theoretical and empirical developments highlight the potential and benefit of the group-level application of the P-E fit theory.
