Interpretative phenomenological analysis

Interpretative phenomenological analysis (IPA) is a qualitative form of psychology research. IPA has an idiographic focus, which means that instead of producing generalization findings, it aims to offer insights into how a given person, in a given context, makes sense of a given situation. Usually, these situations are of personal significance; examples might include a major life event, or the development of an important relationship. IPA has its theoretical origins in phenomenology and hermeneutics, and many of its key ideas are inspired by the work of Edmund Husserl, Martin Heidegger, and Maurice Merleau-Ponty. IPA's tendency to combine psychological, interpretative, and idiographic elements is what distinguishes it from other approaches to qualitative, phenomenological psychology. Sometimes IPA studies involve a close examination of the experiences and meaning-making activities of only one participant. Most frequently they draw on the accounts of a small number of people (6 has been suggested as a good number, although anywhere between 3 and 15 participants for a group study can be acceptable). In either case, participants are invited to take part precisely because they can offer the researcher some meaningful insight into the topic of the study; this is called purposive sampling [i.e. it is not randomised]. Usually, participants in an IPA study are expected to have certain experiences in common with one another: the small-scale nature of a basic IPA study shows how something is understood in a given context, and from a shared perspective, a method sometimes called homogeneous sampling. More advanced IPA study designs may draw together samples that offer multiple perspectives on a shared experience (husbands and wives, for example, or psychiatrists and patients); or they may collect accounts over a period of time, to develop a longitudinal analysis. In IPA, researchers gather qualitative data from research participants using techniques such as interview, diaries, or focus group.
