Different possible goals in health research are outlined: quantifying relationships between variables, identifying associations, exploring experience, understanding process, distinguishing representations, comprehending social practices and achieving change. Three important issues in understanding qualitative approaches to research are discussed: the partiality of our view of the world, deductive and inductive approaches to research, and the role of the researcher in the research process. The methodologies of phenomenology, grounded theory, discourse analysis, ethnography, ethnomethodology and action research are illustrated.
