As the largest segment of the health care workforce, nurses have the greatest potential for advancing systems and services to improve health care delivery in the United States. This article presents a framework for nurse administrators to use in developing direct care nurses in their leadership influence competency as a means of increasing their advocacy potential. A systematic review resulted in establishing a nurse leadership influence framework based on the Kouzes and Posner leadership model. The framework includes leadership competencies by nursing professional organizations and was validated by 2 national nurse leader focus groups. Nurse administrators have the opportunity to adopt an evidence-based leadership influence framework to ensure development of advocacy competency in direct care nurses. The impact of nurse administrators systematically adopting a standardized leadership influence framework will result in setting a strong foundation for nurse advocacy. Successful long-term impacts will result in nurses skillfully integrating leadership influence and advocacy into all aspects of daily practice.
