This second edition is the perfect companion to original theoretical works in nursing for a better understanding of both the theories themselves and the essential questions about nursing theory development. Rather than being a nursing theory survey, the text provides the reader with a deeper understanding of nursing theories through examining them in their conceptual and philosophical contexts. This is a work of international collaboration, with distinguished nurse scholars from the United States, Germany, and Norway, organized around major themes in nursing and health care into which information on specific nursing theories is integrated. It is designed for advanced nursing students, educators, and others interested in nursing theory and concepts.
