Item Sum Double-List Technique: An Enhanced Design for Asking Quantitative Sensitive Questions
Social desirability bias is a problem in surveys collecting data on sensitive or private topics (e.g. sexual practices, health, income, deviant behavior) as soon as the respondent’s true status differs from a social norm. If confronted with sensitive questions, respondents often engage in self-prote...

Social desirability bias is a problem in surveys collecting data on sensitive or private topics (e.g. sexual practices, health, income, deviant behavior) as soon as the respondent’s true status differs from a social norm. If confronted with sensitive questions, respondents often engage in self-protective behavior, either by giving socially desirable answers or by refusing to answer at all. Such systematic misreporting or nonresponse leads to biased estimates and poor data quality. To improve the measurement of sensitive topics in population surveys, various indirect questioning techniques have been proposed in the literature. One example, for the measurement of quantitative sensitive characteristics, is the “item sum technique” (IST). In this study we propose an enhanced design for the IST: the “item sum double-list technique” (ISDLT).
