Interpretive phenomenology (IP) is a form of qualitative research used in the social and behavioral sciences, and is being used by nurse researchers and social scientists. It has been 15 years since a text was published on this topic, yet interest in this methodology has risen. A search on PubMed shows that the number of articles published related to IP has increased by 40% over the past 4 years, compared to the previous 11 years. This text expands on current IP knowledge and provides research exemplars to facilitate application of practice; it will be the definitive text on IP. One of the editors, Patricia Benner, is an international expert on IP. Ideal textbook for qualitative research methodology courses, doctoral students, post-doctoral scholars, and IP nurse researchers. Divided into two parts. Part 1 explores IP from a theoretical and philosophical perspective and addresses methodology issues. Part 2 consists of examples of IP studies that address a wide range of research questions so that readers can more easily integrate IP in their research practice. Patricia Benner, a recognized expert on IP, comments on selected chapters.
