A “paper-assisted personal interview” (PAPI) is a commonly used approach to conducting standardized personal interviews. In this method, the interviewer uses a printed questionnaire to ask the interviewee a set of pre-determined questions. The interviewer records the interviewee’s responses by hand or by entering the answers directly into the questionnaire using a computer or other electronic device. This type of interview is often used in research studies and surveys as it helps ensure that all participants are asked the same set of questions in the same way, promoting consistency and objectivity in the data collected. The use of a standardized questionnaire also facilitates data entry and analysis, making it easier to compare and synthesize responses across multiple interviews. Unlike computer-assisted interviews, pen-and-paper methods of data collection require nearly no technical expertise to implement and leave a great deal of flexibility in the implementation of the survey design. Pen-and-paper surveys are also guaranteed to produce a permanent primary record of data collection.
