Work group diversity, the degree to which there are differences between group members, may affect group process and performance positively as well as negatively. Much is still unclear about the effects of diversity, however. We review the 1997-2005 literature on work group diversity to assess the state of the art and to identify key issues for future research. This review points to the need for more complex conceptualizations of diversity, as well as to the need for more empirical attention to the processes that are assumed to underlie the effects of diversity on group process and performance and to the contingency factors of these processes.

工作组的多样性。

工作小组的多样性（小组成员之间存在差异的程度）可能对小组的过程和绩效产生正向和负面影响。但是，关于多样性的影响，仍然尚不清楚。我们回顾了有关工作组多样性的1997-2005年文献，以评估最新技术并确定未来研究的关键问题。这项审查指出，需要对多样性进行更复杂的概念化，并且需要更多地经验地关注那些被认为是导致多样性对集体过程和绩效产生影响的过程以及这些过程的偶然性因素。
