概要	Digital Straussian grounded theory applies the systematic, coding-driven approach of Strauss and Corbin's grounded theory to digital data sources such as online forums, social media, chat logs, and digital documents. It retains the Straussian paradigm model and three-stage coding structure — open, axial, and selective — while adapting sampling strategies, theoretical saturation criteria, and ethical protocols to the unique features of online and digital research environments.	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.
