We developed a dual-level transformational leadership scale to measure individual-focused behavior at the individual level and group-focused behavior at the group level, and we validated the scale using a sample of 203 members from 60 work groups in a Canadian company. Results show that individual-focused leadership behavior, at the individual level, was positively related to task performance and personal initiative; group-focused leadership behavior, at the group level, was positively associated with team performance and helping behavior. Implications for leadership theory and practice are offered. (Contains 2 tables, 1 figure, and 3 footnotes.)
