In recent years, theorists and practitioners have become critical of the popular conceptualization of leadership as composed of task and relationship types of behaviors for two reasons: (a) other leadership behaviors, such as creating a mission and vision and employee empowerment, are not included in this conceptualization, and (b) under a strict definition of leadership, task-oriented behaviors are more "management" than truly "leadership" behaviors. Gill's (R. Gill, 2006, Theory and Practice of Leadership, Thousand Oaks, CA: Sage) conceptualization of leadership may give researchers and practitioners an alternative way to approach the measurement of leadership behaviors. The current study acquired evidence to support the validity of a measure of the leadership behaviors presented by Gill, which include vision and mission; shared values; strategy; empowerment; and influence, motivation, and inspiration. In comparing the new measure to a preexisting measure of leadership and these measures' respective relationships with organizational commitment, organizational citizenship, and CWBs, results showed support for the criterion and construct validity of the new assessment tool.
