Personality Traits of Registered Nurses in Various Specialties Abstract Nursing is a very demanding profession, requiring an individual to possess a unique set of skills, knowledge, and personal attributes. Personality traits and characteristics of registered nurses are considered to be of great importance as they often influence patient interaction, work satisfaction, and overall career success. Evidence within numerous other industries suggests personality traits also influence job-fit, performance, and retention of employees. While personality traits of oncology, palliative cancer, critical care, and gerontology nurses have been explored, there is little evidence on how these traits can vary across a spectrum work assignments. This study was conducted to measure normal personality traits of registered nurses in the General Medical Unit (GMU), Surgical Intensive Care Unit (SICU), and Neonatal Intensive Care Unit (NICU). Results may suggest distinct personality traits of nurses in these departments as well as whether these traits influence job performance, satisfaction, retention, and ultimately job-fit among successful nurses within this healthcare organization.
