Résumé	A triangulated structured interview applies the triangulation principle — using multiple independent sources, methods, or perspectives to cross-validate findings — to the structured interview format. The researcher administers the same fixed set of questions across different respondent groups, time points, or complementary data sources, then systematically compares the results to confirm, qualify, or explain discrepancies. This strengthens confidence in the accuracy of the data beyond what any single structured interview session could provide.	A Triangulated Survey deliberately combines a structured survey instrument with at least one additional data source — such as interviews, focus groups, observation, or a second survey — so that findings from each source can be cross-validated against the others. Rooted in Denzin's concept of methodological triangulation, the design strengthens credibility by checking whether independent lines of evidence converge on the same conclusions. It is especially common in applied social, educational, and health research.
