Computer-assisted personal interviewing

Computer-assisted personal interviewing (CAPI) is similar to computer-assisted telephone interviewing, except that the interview takes place in person instead of over the telephone.

- The respondent sits in front of a computer terminal and answers a questionnaire on the screen by using the keyboard or a mouse.
- Help screens and courteous error messages are provided.
- The colorful screens and on and off-screen stimuli add to the respondent's interest and involvement in the task.
- This method has been classified as a personal interview technique since an interviewer is usually present to serve as a host and to guide the respondent as needed.
- This approach is used in shopping malls, preceded by the intercept and screening process described earlier.
- It is also used to conduct business-to-business research at trade shows or conventions.

For example, CAPI is used as the method of data collection for the British Crime Survey.

Advantages

This form of interview is substantially cheaper when a large number of respondants is required, because

There is no need to recruit or pay surveyors.
There is no need to transcribe the results into a computer form. The computer program can be constructed so as to place the results directly in a format that can be read be statistical analysis programs such as PSPP or DAP.
The program can be placed on a web site, potentially catching a world wide audience.
