สรุป	Field-based constructivist grounded theory integrates Kathy Charmaz's constructivist grounded theory with active fieldwork in natural settings. Rather than relying solely on retrospective interviews, the researcher enters the participants' world — observing, interacting, and collecting data where social processes unfold — while simultaneously coding and building theory. The result is a grounded substantive theory that is both empirically anchored in real contexts and epistemologically co-constructed between researcher and participants.	Constructivist Grounded Theory (CGT) is a qualitative methodology developed by Kathy Charmaz that systematically builds mid-range theory from empirical data through iterative coding, memo-writing, and theoretical sampling. Unlike the original objectivist version by Glaser and Strauss, CGT treats both data and theory as co-constructed between researcher and participants, acknowledging the researcher's interpretive perspective as an integral part of the analytic process rather than a source of bias to be eliminated.
