概要	Longitudinal phenomenology applies phenomenological inquiry across two or more time points to capture how participants' lived experience of a phenomenon changes, deepens, or transforms over time. Rooted in the phenomenological tradition of Husserl and Heidegger, it adds an explicit temporal dimension — asking not only what an experience is like, but how it evolves. It is used where a single-point interview would miss the processual, shifting nature of lived meaning.	Interpretive phenomenology is a qualitative research design that investigates the meaning people attribute to their lived experiences by combining phenomenological description with hermeneutic interpretation. Rooted in Heidegger's ontology and systematised for social and human sciences by Max van Manen, it moves beyond description to ask what an experience means within a person's broader lifeworld, cultural context, and situated understanding. The researcher's own interpretive horizon is treated as an analytical resource rather than a bias to eliminate.
