Hope has been described in theoretical terms for many years but the recognition of the importance of hope within the practice of nursing is a more recent phenomenon. Despite the recent growth of references to hope within contemporary nursing literature, it is reasonable to suggest that there remain gaps in the substantive knowledge base and that there appears to be room for both additional research and further discursive literature. Accordingly, this series of six articles will explore the nature of hope, review the existing theoretical and empirical work in several discrete areas of nursing, and provide case studies to illustrate the role that hope plays in clinical situations. This article focuses on the origins, background and definitions of hope. The next article will examine hope within mental health nursing, and further articles will focus on hope within palliative care nursing, hope in gerontological nursing and hope in critical and acute care nursing
