Sintesi	Comparative grounded theory applies the systematic inductive logic of grounded theory across two or more distinct groups, settings, or time points. Rather than generating a theory grounded in a single context, it builds theory that explains variation and similarity across contexts, producing conceptually richer and more transferable explanatory frameworks than single-site grounded theory studies.	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.
