Telephone Interview

Telephone interviews continue to provide a cost-effective way to collect data. The usually computer-assisted telephone interviews (CATI) offer the advantage that the interviewer can react to questions and challenge the survey contents if necessary.

Compared to online interviews, telephone interviews have further advantages: Difficult to reach target groups may be easier to reach by telephone. Also, the representativeness of some target groups, e.g. older patients, can be maintained more easily.

For example, CATI is regularly used by us in the context of minute after visit studies, where short interviews are conducted directly after a sales talk.
