Tóm tắt	A Remote Focus Group is a synchronous, moderated group discussion conducted via video or audio conferencing rather than in a shared physical space. Participants — typically 5 to 10 people — join from separate locations and discuss a topic guided by a trained moderator. The method preserves the core strengths of in-person focus groups (group interaction, idea building, spontaneous reactions) while eliminating geographic barriers and reducing recruitment costs. It has become a mainstream qualitative data collection approach, especially following the widespread adoption of video conferencing platforms.	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.
