This document presents a concept analysis of professionalism in nursing. The analysis used Walker and Avant's 8 step method to analyze the concept. Key attributes of professionalism were identified through a literature review and included competence, dedication, ethics, and conduct. A theoretical definition of professionalism in nursing was developed as "characterized by integration of affective, behavioral and cognitive attributes including respect, accountability, truthfulness, autonomy, resilience, specialization and upholding of standards." The analysis provides clarity around professionalism as a concept to help with its assessment and development among nurses.
