本文介绍适于调查敏感性问题的随机化回答法。它是借助于随机化装置以一定概率向被调查者提出陈述,根据回答者答“是”的比例估计人群中敏感性问题的比例。这种方法可避免调查人或在场者知道任一被调查者回答的是哪一种陈述,因而可使被调查者消除心理负担而愿意合作。 This article describes a randomized response method suitable for investigating sensitivity issues. It uses a randomization device to present a survey to the respondent with a certain probability, and estimates the proportion of sensitive questions in the population based on the percentage of respondents who answered “yes”. This method can prevent the investigator or the person in the field from knowing which kind of statement any respondent answers, thus allowing the respondent to eliminate the psychological burden and willing to cooperate.
