Paper Assisted Interviewing(PAI)
Prior to the 1980s, essentially all survey data collection that was done by an interviewer was done via ‘paper-and-pencil interviewing’, which came to be known as PAPI.
PAPI still is used in instances where data are being gathered from a relatively small sample on an accelerated start-up time basis, and/or the time and effort it would take to program (and test) the instrument into a computer-assisted version simply is not justified.
In order the answers are representative; the respondents should be selected as a random sample.
For the interview the following characteristics are applied:
- It is clear who answers
- Percentage of completed interviews is higher than the return of the questionnaire
- It is hard to skip a question
- Interviewer gives the respondent more comfort than the actual questionnaire (for example, he fills in the questionnaire himself)
- Problem may be the feeling of non-anonymity with sensitive questions (respondent is in direct contact with the interviewer)
- Expensive technology
- Time duration demands lead to a smaller size of the examined sample
- Trained interviewers are needed
