Telephone Interviewing: A Reappraisal and a Field Experiment

A review of 25 empirical evaluations of telephone interviewing indicated that the method compares favorably with face-to-face interviewing in terms of the range of subject matter that can be covered, length of interview, response rates, quality of data, and, most conspicuously, cost. In order to surmount some of the limitations of previous empirical comparisons of the two interviewing methods, a field experiment was conducted wherein 93 interviewers administered either face-to-face or telephone interviews to 470 similarly selected household respondents. Although the two methods did not differ significantly in terms of response rates, codeability of data, or reporting on sensitive issues, they did differ somewhat in interview length and the sex composition of the samples obtained.
