Interpretative phenomenological analysis

Interpretative phenomenological analysis (IPA) is an approach to psychological qualitative research with an idiographic focus, which means that it aims to offer insights into how a given person, in a given context, makes sense of a given phenomenon. Usually these phenomena relate to experiences of some personal significance, such as a major life event, or the development of an important relationship. It has its theoretical origins in phenomenology and hermeneutics, and key ideas from Edmund Husserl, Martin Heidegger, and Maurice Merleau-Ponty are often cited. IPA is one of several approaches to qualitative, phenomenological psychology. It is distinct from other approaches, in part, because of its combination of psychological, interpretative, and idiographic components.

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 which 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. Typically, these are approached from a position of flexible and open-ended inquiry, and the interviewer adopts a stance which is curious and facilitative (rather than, say, challenging and interrogative). IPA usually requires personally-salient accounts of some richness and depth, and it requires that these accounts be captured in a way which permits the researcher to work with a detailed verbatim transcript.
