Telephone surveys had a lower cooperation rate than mobile web surveys among contacted participants. South Korea's PXA had historically used telephone surveys but faced low response rates and operational concerns. Telephone surveys involved trained interviewer calls with identity verification and up to five contact attempts. The article identifies work interruption, shared environments, and reluctance to answer unknown numbers as telephone survey barriers. Interviewer-led telephone surveys may produce more positive scale responses than self-administered surveys.
