Tóm tắt	A telephone-assisted focus group is a qualitative data collection technique in which a moderator facilitates a structured group discussion among multiple participants connected simultaneously via a telephone conference bridge or audio platform. It preserves the core interactive dynamics of traditional focus groups — group synergy, probing, and spontaneous reactions — while eliminating the need for geographic co-location, making it suitable for hard-to-reach, geographically dispersed, or mobility-constrained populations.	A telephone-assisted semi-structured interview is a qualitative data collection technique in which a researcher conducts a guided conversation with a participant over the telephone, using a pre-designed topic guide that balances predetermined questions with freedom to probe and explore. It combines the flexibility of semi-structured interviewing with the geographic reach and logistical convenience of telephone communication, making it widely used in health, social, and organizational research.
