Résumé	Longitudinal Constructivist Grounded Theory combines Kathy Charmaz's constructivist variant of grounded theory — which foregrounds the co-construction of meaning between researcher and participants — with a multi-wave, time-extended data collection design. Rather than capturing a single snapshot, the researcher returns to the same participants across two or more time points, allowing the emergent theory to track how processes, identities, and social meanings develop, shift, or stabilise over time.	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.
