Despite its growing role in survey research, the telephone survey has been largely neglected with respect to the design and testing of statistical procedures for assuring response privacy (e.g., randomized response techniques). This paper demonstrates that such procedures are no less feasible to administer in telephone surveys than in face-to-face surveys. Both randomized response techniques and alternatives to randomized response are considered.
