概要	Descriptive Phenomenology, systematised by Amedeo Giorgi at Duquesne University, is a rigorous qualitative method for uncovering the general psychological structure of a lived experience. Drawing directly on Husserl's transcendental phenomenology, Giorgi's four-step procedure — epoché, whole reading, meaning-unit discrimination, and transformation into disciplinary language — produces a stable, replicable description of what makes an experience essentially what it is, without theoretical interpretation or causal explanation.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
