In the 21st century, theories of leadership have re-emerged, with a focus on the leader's value base. Copeland (2014) identified 11 leadership theories situated within the sphere of values-based leadership; however, these all pertained to a business-management focus.In conducting this review, it emerged that within nursing, three main leadership theories appear under the umbrella of the values-based leadership domain. As such, this review went beyond values-based leadership literature, to capture data related to authentic leadership, servant leadership and congruent leadership, aiming to gain a wider understanding of values-based leadership. This paper begins with an overview and definition of values-based leadership and the three leadership theories identified, before describing a literature review that explored each of the theories, supporting a wider understanding from a nursing perspective.
