Patient outcome data are an important factor in healthcare. Reports by the Institute of Medicine between 1999 and 2001, as well as recent research by Linda Aiken and her colleagues have added more emphasis to measures that can be taken to improve patient outcomes. Because of the role they play in healthcare facilities, nurse leaders are in a position to take the lead in improving patient outcomes. There is evidence to suggest that nurse leaders' transformational leadership behaviors are associated with positive patient outcomes. The purpose of this project was to identify the effect of transformational leadership skill-building training on nurse leaders' behavior in the acute care setting. The project included assessments of nine nurse leaders by those nurses which are supervised by the nurse leaders. The results indicated the nurse leaders' behavior score of 3.1 was in the transformational range (3.0-3.75.) Transformational leadership skill-building training followed the assessment process. A post training evaluation by the previous assessors followed the training. The distribution of the transformational leadership behavior scores did not change following the training.
