सारांश	Triangulated in-depth interviewing applies Denzin's triangulation logic to the in-depth interview method by deliberately combining multiple sources of convergent evidence — different informants, interviewers, time points, or corroborating data types — to strengthen confidence in qualitative findings. Rather than relying on a single interview account, the researcher gathers rich, open-ended accounts from several vantage points and cross-checks them for consistency and divergence, treating agreement as corroboration and disagreement as analytically meaningful.	The multi-source in-depth interview is a qualitative data collection strategy in which extended, open-ended interviews are conducted with participants drawn from two or more distinct source groups — such as providers and clients, managers and staff, or experts and laypeople. Collecting data across diverse informant positions enriches description and enables the researcher to examine a phenomenon from multiple vantage points within a single study.
