PURPOSE
Research on sensitive and private topics relies heavily on self-reported responses. Social desirability bias may reduce the accuracy and reliability of self-reported responses. Anonymous surveys appear to improve the likelihood of honest responses. A challenge with prospective research is maintaining anonymity while linking individual surveys over time.
METHODS
We have tested a secret code method in which participants create their own code based on eight questions that are not expected to change.
RESULTS
In an ongoing middle school trial, 95.7% of follow-up surveys are matched to a baseline survey after changing up to two-code variables. The percentage matched improves by allowing up to four changes (99.7%).
CONCLUSIONS
The use of a secret code as an anonymous identifier for linking baseline and follow-up surveys is feasible for use with adolescents. While developed for violence prevention research, this method may be useful with other sensitive health behavior research.
目的
敏感和隐私主题的研究很大程度上依赖于自我报告的反应。社会期望偏差可能会降低自我报告反应的准确性和可靠性。匿名调查似乎更有可能获得真实的反应。前瞻性研究的一个挑战是在随着时间的推移将个体调查联系起来的同时保持匿名。
方法
我们已经测试了一种密码方法，参与者根据八个不太可能改变的问题创建自己的代码。
结果
在一项正在进行的中学试验中，在改变多达两个代码变量后，95.7%的随访调查与基线调查相匹配。通过允许最多四个更改（99.7%），匹配的百分比得到提高。
结论
对于将基线和随访调查联系起来的使用密码作为匿名标识符的方法对于青少年来说是可行的。虽然这种方法是为预防暴力研究开发的，但它也可能对其他敏感健康行为研究有用。
