Asking Sensitive Behavioral Questions in Telephone Interviews

This article presents the results of a small pilot study to test the feasibility of telephone interviews for collecting highly sensitive data for a study of the etiology of trophoblastic disease. The study design allowed us to compare data from telephone and face-to-face interviews. The results suggest that very sensitive information can be obtained by telephone and that respondents interviewed by telephone may be more willing to report socially proscribed behavior than respondents interviewed face-to-face. A number of unanswered issues are suggested for future research.
