Do interviewers juggle filtering in surveys? Evidence from a cross-classified multilevel approach
Contemporary survey designs extensively use filtering techniques in personal (face-to-face) as well as telephone interviews. In general, filter questions serve as forks circumventing follow-up questions that do not apply. While the purpose of filter questions is to reduce respondent burden (e.g., Bosley, Dashen, & Fox, 1999), interviewers can exploit these questions to cut interviews short. Such interviewer manipulation could distort the validity of survey data. Analyzing the conditions that encourage such interviewer behavior is the aim of our study.
