概要	Longitudinal Straussian Grounded Theory applies the systematic coding procedures of Strauss and Corbin's grounded theory — open, axial, and selective coding — to data gathered across multiple time points. Rather than producing a static snapshot of a social phenomenon, it tracks how processes, identities, or conditions evolve, generating a substantive theory grounded in change over time. It is particularly powerful for studying social processes that unfold across months or years.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
