Tóm tắt	A Triangulated Research Diary is a qualitative data collection approach in which a researcher's ongoing reflective diary is used as one strand within a triangulated data collection strategy. The diary records observations, decisions, emotions, and emerging interpretations across the study, while at least one other data source — such as interviews, documents, or observations — is collected in parallel. Cross-checking diary entries against other sources increases the credibility and depth of the findings.	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.
