Cognitive diversity and team creativity: Effects of team intrinsic motivation and transformational leadership

We theorized and tested an integrated model for the relationship between cognitive diversity and team creativity. This model involves team intrinsic motivation as a mediator and transformational leadership as a moderator. The Hierarchical Linear Modeling results using 62 teams revealed that transformational leadership moderated cognitive diversity's direct effect on team intrinsic motivation and indirect effect on team creativity via team intrinsic motivation, such that the effects were positive when transformational leadership was high, but negative when transformational leadership was low.
