The nursing literature has suggested that the lack of Emotional Intelligence (EI) among nurse leaders has been one of the major contributing factors for nurse dissatisfaction leading to higher rates of nurse turnover and a decline in the rate of nurse retention. Many researchers have also argued that the lack of EI competencies among nurses reduced the art of nursing science to the role of a technician, which has compromised the quality of care, the healthcare outcomes and increased cost. Therefore; the concept of EI has become one of the most essential factors in the success equation necessary for transformational leadership in patient safety and workforce issues as nurse leaders can no longer use outmoded ways to lead organizations. Although some educators and practitioners embraced the construct, yet the nursing research base on the constuct continues to be scarce and requires further investigation in various areas in nursing. The purpose of this capstone project was to measure the level of EI among advanced practice nurses as healthcare leaders’ pre, post and six weeks after an educational intervention on EI. the rationale for the project was to predict the need for more education and training on EI among advanced practice nurses.
