Authentic Leadership Questionnaire

The Authentic Leadership Questionnaire (ALQ) is the dominant instrument for measuring authentic leadership, a positive leadership construct developed in the mid-2000s by Bruce Avolio, William Gardner, Fred Luthans, and colleagues. Authentic leaders are defined as those who are deeply aware of their own values, transparent in their relationships, balanced in processing information, and guided by an internalized moral compass. Gardner and colleagues' 2005 self-based model in The Leadership Quarterly laid out how leader authenticity develops and shapes followers, and Walumbwa and colleagues' 2008 Journal of Management paper operationalized the construct as a four-dimension higher-order factor and validated the ALQ across samples in the United States and China. The questionnaire measures self-awareness, relational transparency, balanced processing, and internalized moral perspective, and links them to follower trust, citizenship behavior, satisfaction, and performance. It anchored the rapid rise of authentic-leadership research within the positive-organizational-behavior movement.
