Tóm tắt	Selective coding is the third and final analytic phase of grounded theory, in which the researcher systematically identifies one central or core category that integrates all other major categories developed during open and axial coding. The outcome is a coherent, data-grounded substantive theory that explains the main social process or phenomenon under study. First formalized by Glaser and Strauss (1967) and later elaborated by Strauss and Corbin (1990) and Kathy Charmaz (2006), selective coding transforms fragmented mid-level categories into a unified theoretical account.	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.
