Research on Correction Method of Response Effects in the Item Count Technique

间接提问方法，包括物品清点技术，经常被用来调查非法或社会不受欢迎的行为。本研究探讨了影响题数估计的漏报效应产生的原因及纠正方法。调查结果显示，通过要求清单中不适用项目的数量以及普通项目计数答复中适用项目的数量，可以抑制少报效应。

Indirect questioning methods including the item count technique are often used to investigate illegal or socially undesirable behaviours. In this research, the cause and correction method of the underreporting effect, which disturbs the item count estimates, are explored. The survey results revealed that the underreporting effect could be suppressed by requiring the number of non-applicable items among the list in addition to the ordinary item count response, the number of applicable items.
