A classic text is back with fresh, comprehensive nursing theories, critiques, and philosophies. Nursing Theorists and Their Work, 9th Edition provides you with an in-depth look at 39 theorists of historical, international, and significant importance. This new edition has been updated with an improved writing style, added case studies, critical thinking activities, and in-depth objective critiques of nursing theories that help bridge the gap between theory and application. In addition, the six levels of abstraction (philosophy, conceptual models, grand theory, theory, middle-range theory, and future of nursing theory) are graphically depicted throughout the book to help you understand the context of the various theories.
