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
