IntroductionAccording to Markham, “It could be said that the world is made up of what is relatively measurable and what is relatively unmeasurable. Different schools of thought place different levels of emphasis on what is measurable and what is not measurable.” Qualitative research methodology, unlike quantitative research, is used to discover people's feelings, opinions, behaviors, reasons for behaviors, attitudes and beliefs. This paper aims to review and compare three qualitative research methodologies: Interpretative Phenomenological Analysis (IPA), Discourse Analysis (DA) and Grounded Theory (GT), and identify how they can be applied in coaching research. Interpretative Phenomenological Analysis (IPA) Interpretative Phenomenological Analysis (IPA) is an experiential qualitative methodology developed by Jonathan Smith, for use in new areas of psychological research such as health psychology. Shaw (2010) states that: “The central aim of IPA is to understand what personal and social experiences mean to the people who experience them”. This is achieved through exploring participants' experiences from their personal perspective, the process which they use to make sense of experiences and the meaning they attach to their experiences. The IPA recognizes that this exploration cannot be achieved independently of the researchers' perceptions and worldview of the participant's experience. IPA uses open-ended, non-directive questions within semi-structured interviews or diaries (written, audio, or video) with researchers using the actual transcript to perform the analysis Speech (DA)”. ......half of paper ......lysis in psychology (pp. 187-199).
