In health professions education, we are often interested in researching change over time, for example the development of professional identity or the adoption of new practices. Taking a longitudinal qualitative approach to such research can provide valuable insights. In this article, we present some longitudinal qualitative methods to support researchers interested in getting started with this type of research. We discuss what longitudinal qualitative approaches offer, consider the challenges and suggest how to go about it. We also highlight some specific ethical considerations that may arise in longitudinal studies.
