Abstract
This article reports on a major, large-scale two-year empirical study to investigate intercultural competencies among global leaders and the relationship of these competencies to criteria of high performance global leadership. The study was designed to contribute to the emerging field of global leadership research by identifying and measuring proximal attributes and leadership criteria as suggested by Zaccaro's trait-based leadership model (American Psychologist 62: 6-16, 2007). Only global leaders were included in the study - CEO's, General Managers, Function Heads, or those with Profit and Loss responsibility for their businesses. These 1867 leaders of 13 nationalities were engaged in leading people across cultures - either on international assignment or working from their home base. A set of six intercultural competencies and three criteria of global leadership success were identified and compared across nationalities. The competencies were measured and used to predict success over time. Applications are discussed in terms of global leadership assessment and development.
