Computer Aided Telephonic Interviews

Interviews carried out by telephone are guided by a questionnaire displayed on the screen of a computer. The interviewer records answers via the keyboard to correspond with the pre-coded responses displayed on the screen.

CATI research has considerable advantages:

  • The interviewer is left free to concentrate on the interview itself as the routing instructions are taken care of
  • Data is entered directly and the subsequent transactions of data processing are eliminated – cost and punching errors are reduced
  • The whole process is speeded up because data is entered as it is obtained
  • At intervals during the survey, the researcher can interrogate the computer to examine the results
  • An analysis of results can be obtained immediately after the last interview has been completed
