Consequences Of Asking Sensitive Questions In Surveys

I review selected articles from the survey methodology literature on the consequences of asking sensitive questions in censuses and surveys, using a total survey error (TSE) framework. I start with definitions of sensitive questions and move to examination of the impact of including sensitive questions on various sources of survey error-specifically, survey respondents' willingness to participate in a survey (unit nonresponse), their willingness to respond to next rounds of interviews (wave nonresponse), their likelihood to provide an answer to sensitive questions after agreeing to participate in the survey (item nonresponse), and the accuracy of respondents' answers to sensitive questions (measurement error). I also review the simultaneous impact of sensitive questions on multiple sources of error in survey estimates and discuss strategies to mitigate the impact of asking sensitive questions on measurement errors. I conclude with a summary and suggestions for future research.
