A short measure of transformational leadership

This study reports the development of a short measure of transformational leadership: the Global Transformational Leadership scale (GTL). The study sample was 1,440 subordinates who assessed the leader behaviour of 695 branch managers in a large Australian financial organisation. Exploratory and confirmatory factor analysis showed that the GTL measured a single construct of leadership and had satisfactory reliability. Evidence for the convergent and discriminant validity is presented. We conclude that the GTL has a number of potential uses as an assessment and selection tool and in leadership research.
