The purpose of this study was to begin exploring the nature of leadership behavior and style, as it relates to team functionality. The extent to which the problems we face grow and become more complex; solutions require multiple perspectives, requiring researchers to be prepared to lead large groups of collaborators from a variety of disciplines. This study sought to explore the self-perceptions of principal investigators related to their leadership style and team functionality. Using the Multifactor Leadership Questionnaire developed by Bass and Avolio (1995) and Lencioni's Team Assessment (2002), it was found that transformational leadership was self-perceived to be used the most in contrast to transactional leadership behaviors. With respect to team functionality, absence of trust and inattention to results showed the greatest concern to principal investigators, yet fear of conflict did not.
