摘要	An online structured interview applies the classical structured interview protocol — a fixed set of predetermined questions asked in a fixed order — via internet-mediated channels such as video conferencing, synchronous chat, or email. Every participant receives the exact same questions, enabling systematic comparison across respondents while eliminating geographic barriers. It combines the standardization benefits of face-to-face structured interviewing with the reach, cost efficiency, and scheduling flexibility of online data collection.	An online focus group is a moderated group discussion conducted via internet-based platforms — video conferencing, text chat, or asynchronous forums — to explore shared perceptions, attitudes, and experiences on a defined topic. It inherits the group-interaction dynamics of the traditional focus group while removing geographic barriers and enabling data collection from dispersed or hard-to-reach populations.
