תקציר	Longitudinal Institutional Ethnography (longitudinal IE) combines Dorothy Smith's sociology of standpoint — institutional ethnography — with repeated data collection over time to trace how institutional texts, relations, and ruling practices shape people's everyday lives across a temporal span. By revisiting the same participants, settings, or documents at multiple time points, it reveals how institutional coordination evolves, accumulates, or intensifies over weeks, months, or years.	Longitudinal grounded theory is a qualitative research design that applies grounded theory's inductive, iterative logic to data collected from the same participants or settings across multiple time points. It is used to build substantive theory that accounts not only for social processes but also for how those processes unfold, shift, and are renegotiated over time. The approach is particularly suited to studying change, trajectory, and temporal experience in social and health research.
