Tóm tắt	Multi-source Mobile Experience Sampling extends the standard ESM design by simultaneously collecting repeated momentary self-reports from two or more linked informant types — such as patient and caregiver, employee and supervisor, or partners in a dyad — via their smartphones. Signals are delivered concurrently across sources, enabling researchers to examine convergences and discrepancies between informants' real-time experiences and to model interpersonal dynamics at the moment they unfold in daily life.	Multi-source participant observation is a qualitative data collection technique in which the researcher is embedded within a social setting and systematically gathers observational data from multiple vantage points, sites, or informant roles simultaneously. By triangulating across sources, the method strengthens credibility and provides a richer, more complete picture of social phenomena than single-site observation alone.
