对所谓的敏感问题获得有效的答案是调查研究中一个古老的问题。已经开发了各种技术来保证匿名和尽量减少受访者的危险感。两种这样的技术是随机应答技术（RRT）和不匹配计数技术（UCT）。在这项研究中，作者评估了不同实施RRT（使用强迫反应设计）在计算机辅助环境中的有效性，并将RRT的使用与UCT的使用进行了比较。这些技术是根据各种质量标准进行评估的，例如它们提供的流行率估计，它们的易用性以及受访者对这些技术的信任。结果表明，RRT是有问题的几个领域，如有限的信任，他们激发和nonresponse，RRT估计是不可靠的，由于一个强大的错误没有偏见，特别是对于更敏感的问题。然而，与RRT相比，UCT在所有评价指标上表现良好。作者得出结论，在自我管理的调查中，UCT是RRT的一种有前途的替代方法，未来的研究应致力于评估和改进该技术。
Gaining valid answers to so-called sensitive questions is an age-old problem in survey research. Various techniques have been developed to guarantee anonymity and minimize the respondent's feelings of jeopardy. Two such techniques are the randomized response technique (RRT) and the unmatched count technique (UCT). In this study the authors evaluate the effectiveness of different implementations of the RRT (using a forced-response design) in a computer-assisted setting and also compare the use of the RRT to that of the UCT. The techniques are evaluated according to various quality criteria, such as the prevalence estimates they provide, the ease of their use, and respondent trust in the techniques. The results indicate that the RRTs are problematic with respect to several domains, such as the limited trust they inspire and nonresponse, and that the RRT estimates are unreliable due to a strong false no bias, especially for the more sensitive questions. The UCT, however, performed well compared to the RRTs on all the evaluated measures. The authors conclude that the UCT is a promising alternative to RRT in self-administered surveys and that future research should be directed toward evaluating and improving the technique.
