With the emergence of transformational and transactional leadership study there has been resurgence of interest in the study of leader traits and abilities. The current interest is in those individuals who are able to bring about the transformation of organizations within a rapidly changing environment. The transforming leadership behaviors are different than those studied during the past century of leadership research in that they require visioning, conceptualizing, reframing, articulating, personal advocacy, and purposeful role modeling for employee benefit and growth. This study examined the nature of the relationship between certain thinking and behaving preferences and the demonstration of transactional and transformational leadership behaviors. Utilizing a sample of leaders and their direct reports from the rapidly changing health care industry, the degree of transformative and transactional leadership behaviors was measured by leader and rater forms of the Multifactor Leadership Questionnaire (MLQ). Utilizing the same sample of leaders, the thinking and behaving preferences of these individuals were identified using the Emergenetics\sp{\rm TM} Profile. Multivariate multiple regression was conducted to explore the predictive relationship between the thinking and behaving preferences and the demonstration of transformational and transactional leader behaviors. Results of analyses indicated that the social awareness thinking preference and the behavioral attributes of assertiveness, flexibility, and expressiveness demonstrated predictive ability in the emergence of most transforming leader behaviors as defined by the MLQ
