Even though ethical competence represents a sine qua non competence in nursing practice, no consensus can be found in literature with respect to its definition. The identification of its components and their relationships resulting from this integrative review adds to the clarification of its definition. It paves the way for other studies that will contribute to a better understanding of its development, especially among nursing students and practicing nurses, as well as the factors that may exert an influence. More adapted education strategies can thus be put forward to support its development.
