요약	A longitudinal research diary is a structured, ongoing record kept by the researcher throughout an extended study, capturing observations, decisions, emerging insights, and methodological reflections at repeated intervals over weeks, months, or years. It functions simultaneously as a reflexivity tool and a secondary data source, documenting how the inquiry evolves, how researcher positionality shifts, and how contextual changes influence the data collection process across time.	The diary method is a data-collection technique in which participants record their thoughts, behaviours, events, or experiences in their own words at regular or event-contingent intervals over a defined study period. By capturing data close in time to the event, diaries reduce retrospective recall bias and give researchers access to the texture of everyday life as it unfolds — something one-off surveys and retrospective interviews cannot provide.	A research diary is a systematic, dated log maintained by the researcher throughout a study to record methodological decisions, emergent observations, analytical hunches, and reflections on researcher positionality. Unlike a participant diary, it is authored by the researcher and functions simultaneously as a data source, an audit trail, and a reflexivity instrument.
