Qualitative research essentials for medical education.

This paper offers a selective overview of the increasingly popular paradigm of qualitative research. We consider the nature of qualitative research questions, describe common methodologies, discuss data collection and analysis methods, highlight recent innovations and outline principles of rigour. Examples are provided from our own and other authors' published qualitative medical education research. Our aim is to provide both an introduction to some qualitative essentials for readers who are new to this research paradigm and a resource for more experienced readers, such as those who are currently engaged in a qualitative research project and would like a better sense of where their work sits within the broader paradigm.
