In this chapter, we briefly trace the history of the neo-charismatic movement and review Bass and Avolio’s full-range leadership theory (FRLT). We present the FRLT as the flame bearer of the movement, and argue that it should be used as a platform to integrate similar leadership theories. We identify conditions that may moderate the factor structure of the FRLT, and review the validity of the Multifactor Leadership Questionnaire – the instrument underlying the FRLT. Furthermore, we identify theoretical deficiencies in the FRLT and propose the addition of a broad class of behaviors labeled instrumental leadership, which, we argue, is distinct from transformational, transactional, and laissez-faire leadership. Finally, we discuss the utility of dispositional variables in predicting the emergence of leadership.
