Computer-Assisted Personal Interviewing (CAPI)

Computer-assisted personal interviewing (CAPI) refers to survey data collection by an in-person interviewer (i.e. face-to-face interviewing) who uses a computer to administer the questionnaire to the respondent and captures the answers onto the computer.

CAPI method can enhance the quality of survey data in a number of ways:

  • Routeing problems within the questionnaire are eliminated
  • Interviewers cannot miss questions or ask the wrong questions
  • Questions are 'customised' correctly
  • Mathematical calculations can be carried out within the program
  • The computer checks for inadmissible or inconsistent responses
  • Errors from separate data entry are eliminated.
