这篇文章对如何在人口调查中衡量敏感话题的持续辩论有所贡献。我们提出了一种可用于定量敏感变量测量的新技术：项目和技术（IST）。该方法与项目计数技术密切相关，项目计数技术是为测量二分类敏感项目而开发的。首先，我们对我们的新技术进行了描述，并讨论了如何分析IST收集的数据。其次，我们介绍了CATI对德国未申报工作的调查结果，其中IST已被应用。使用实验设计，我们将IST与直接提问进行比较。我们的实证结果表明，IST是一种很有前途的敏感问题数据收集技术。最后，我们讨论了新技术的局限性，并概述了未来研究可能的改进。
This article contributes to an ongoing debate about how to measure sensitive topics in population surveys. We propose a novel technique that can be applied to the measurement of quantitative sensitive variables: the item sum technique (IST). This method is closely related to the item count technique, which was developed for the measurement of dichotomous sensitive items. First, we provide a description of our new technique and discuss how data collected by the IST can be analyzed. Second, we present the results of a CATI survey on undeclared work in Germany, in which the IST has been applied. Using an experimental design, we compare the IST to direct questioning. Our empirical results indicate that the IST is a promising data-collection technique for sensitive questions. We conclude by discussing the limitations of the new technique and outlining possible improvements for future studies.
