A complete and detailed book focused on middle range theories. The text examines theories and their applications in clinical nursing research and practice. In this fourth edition, the change of the subtitle to Application to Nursing Research and Practice better reflects the dynamic relationship between theory, research, and practice with an increased emphasis on applications of middle range theories to practice. The authors provide expert advice on selecting the appropriate theory for a nursing research project and developing the critical thinking skills needed to critique theories. Every theory chapter includes examples of the theories and ways they are used in research, as well as sample applications, and critical thinking exercises. Students can go to thePoint to find a related Theory Analysis exercise and practice their critiquing skills by doing the exercise and then comparing it with a crtique done by an expert in the field.
