الملخص	Triangulated non-participant observation systematically combines two or more independent non-participant observation streams — using multiple observers, different time points, or distinct vantage points — to cross-validate field records of naturally occurring behaviour. The researcher remains outside the setting as a detached observer, and triangulation across sources reduces single-observer bias while strengthening the credibility of descriptive findings.	Multi-source non-participant observation is a qualitative data collection strategy in which a researcher systematically observes naturally occurring behaviour across two or more distinct settings, sites, or data sources without joining or influencing the activity being studied. By deliberately excluding the researcher from participation and drawing on multiple independent observational vantage points, the approach strengthens credibility through methodological triangulation while preserving the unobtrusiveness that protects naturalistic behaviour.
