Computer-assisted personal interviewing

From Computer Assisted Personal Interviewing (CAPI) (computer -assisted personal interviewing ) is when an interviewer with a notebook computer on which the questionnaire program runs, the visits interviewee and then together passes through the questionnaire on the screen with her. Technically, it makes no difference whether the interviewer asks the questions and the answers inputs or whether the interviewee considered themselves the screen and uses the keyboard.

Most CAPI systems are variants or derivatives of CATI systems. The following system components can be distinguished:

• The programming environment for the questionnaire and the runtime system for its implementation in the Interview: This system parts are usually identical to those for the CATI application, because it makes no difference whether the computer in call center is standing or on a table between the to- interviewer and the interviewer.

• The address management: While CATI systems, the addresses of a project are managed centrally, must be pre- divided in CAPI systems, the address database, for example, according to regional criteria into packets, which are then passed to different interviewers. The address management supported the allocation of addresses, sending it to the interviewer (usually by means of file transfer or as e- mail attachments ), regular, eg daily Back transfer of addresses with the respective completion status and their merging and evaluation at the central project management. Along with the addresses and the data collected will be sent for the upload.

• Project Statistics: The indicators of the status of the various projects are presented in tables and chart form.

• Language Support: This component supports the transfer of the questionnaire into another language survey.

The components of project statistics and language support are often identical in CATI, CAPI and also in Web -based survey systems.
