概要	In vivo coding is a qualitative first-cycle coding strategy in which the researcher uses the participants' own words or short phrases verbatim as code labels, rather than imposing researcher-generated or theoretical language. The technique preserves the voice, meaning, and conceptual priorities of participants, making it especially valuable in grounded theory, phenomenology, and any study where honouring the emic (insider) perspective is central to analytic integrity.	Phenomenology is a qualitative research approach that investigates how participants live through and make sense of a specific experience. Rooted in the philosophy of Edmund Husserl and extended by Martin Heidegger, it aims to reveal the essential structures of lived experience rather than to measure or predict outcomes. The two most widely applied variants are Husserl's transcendental phenomenology, which seeks universal essences, and Heidegger's hermeneutic phenomenology, which emphasises interpretation within context.
