Abstract: Over the last century the nursing profession has drawn from numerous theories and disciplines to construct its own theoretical foundations. While this diversity and flexibility may be one of the nursing profession's strengths it may have contributed to nurses' difficulty in explaining the complexities of their every day clinical work. This is a particular challenge for the domain of mental health nursing. This dissertation discusses how nursing models that have credibility at a clinical level can contribute to informing and advancing nursing practice. Models can achieve this by assisting nurses to conceptualise and articulate what it is they do that makes a difference to patient outcomes. Through this process nurses can maintain a distinct professional identity and establish themselves as effective members of multidisciplinary health team. Specifically, the application and limitations of Godkin's (2001) proposed model of a 'healing presence' to the author's own practice in a one-to-one nurse-adolescent client relationship in the mental health nursing is examined. It is claimed that a 'healing presence' provides a meaningful way to understanding the author's own practice. The proposed model of a 'healing presence' embraces the diversity of her background, and allows the author to maintain a nursing identity by providing a nursing framework to critique her practice, furthering her understanding of what it is that 'expert' nurses do and how this impacts on patient outcomes. Also suggested is that a 'healing presence' can contribute to the author's own and other nurses advanced nursing practice by making nursing visible to the multidisciplinary health team and to articulate “what it is that I do 'when I am nursing'”. Through presenting this dissertation, the author wishes to inspire other nurses to examine and understand their own practice.
