Nursing specialty organizations such as the Oncology Nursing Society, the AACN, and the Emergency Nurses Association have created programs for leadership development and, along with the American Nurse Credentialing Center, offer certifications in leadership. The numbers of books and manuscripts on nursing leadership have also increased in recent years. A cursory search of the CINAHL data base using the search term ‘‘leadership development’’ yielded 109 publications from January 1, 1996, to December 31, 2000; 316 from 2001 to 2005; and an increase to 440 from 2006 to 2011.
