ABSTRACT
This chapter focuses on the interviewers and their contribution to achieving interview privacy. Interviewers are key in enforcing the privacy requirement that is part of the protocol for many surveys. Yet achieving and maintaining privacy can be difficult. Measuring between-interviewer variation in interview privacy and the contribution of interviewer characteristics to such variation is essential for identifying modifiable factors for interventions aimed to reduce the presence of a third party and for designing training materials or protocols to aid interviewers in establishing privacy. A weighted two-level logistic regression model was used (respondents in level 1, interviewers in level 2) to estimate the between-interviewer variance and predict the presence of a third party during the interview using interviewer sociodemographic characteristics and attitudes toward privacy. Interviewers varied significantly in the rate of interview privacy; while some interviewers had no private interviews, others conducted all their interviews in a private setting.
