Zhrnutie	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.	A longitudinal survey collects structured questionnaire data from the same individuals or units at two or more distinct points in time. By tracking the same respondents across waves, researchers can distinguish genuine change from stable individual differences, establish temporal ordering between variables, and model trajectories of attitudes, behaviors, or outcomes in ways that a single cross-sectional snapshot cannot support.	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.
