Σύνοψη	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.	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.
