概要	Interpretive grounded theory is a qualitative methodology that builds substantive theory inductively from data while working from an interpretivist epistemological stance. Developed most fully by Kathy Charmaz, it holds that researcher and participant co-construct meaning, that categories are created rather than discovered, and that the resulting theory is one plausible account among others rather than an objective rendering of social reality.	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.
