CAPI surveys: main fields of application

Let’s see now when choosing CAPI technique rather than other techniques is a winning move, if not the only move.

Surveys in shopping centers: you can reach an heterogeneous and wide target. You can interview respondents in an easy and rapid way;

Exit-poll: CAPI methodology is the most used for this specific type of survey. You can still reach an extended target and you don’t have to comply with restrictions based on age or education, for example;

High profile categories: when the target is an high profile professional figure (like MDs) completing the interview can be a difficult task because of their limited availability. This issue can be overcome when the interviewer schedules an appointment and goes to the respondent to interview him/her;

Mistery shopping: CAPI surveys allow mistery client to collect information in a discreet way completing the questionnaire direclty on his/her smartphone as if he/she’d be texting someone.

CAPI surveys: main features

Interviewer and respondent are one in front of the other (face-to-face mode): the data collector has to insert answers with the possibility to confront with the respondent and clarify possible concerns.
Also, CAPI can represent an additional support to data collector: being able to interview various type of people means getting a wider and more representative sample.


The most important benefit is the opportunity to interview everybody. In fact, a CAPI survey guarantees a better quality of collected data.

Also, another considerable benefit is convenience. Data inserted into the mobile device are sent automatically to the server so that they can be immediately available to export or to use for reports.
Convenience, ease of use and interviewer’s presence on field permit to reach a wider target and extremely heterogeneous.
Thanks to most advanced software, like IdSurvey, recording GPS coordinates allows a better but essential control on interviewers work.
Lastly, in mistery shopping surveys, mistery clients can shoot a photo and insert it automatically in the questionnaire.
