受访者驱动抽样(RDS)被广泛采用为评估艾滋病毒和其他性传播感染在难以接触到的人群中的流行率和风险因素的一种方法。如果进行了形成性研究，在几种情况下正确实施RDS的失败本可以避免的。然而，到目前为止，还没有发表的文献涉及在RDS研究准备中使用形成性研究。本文以波斯尼亚和黑塞哥维那的巴尼亚卢卡、泰国的曼谷、黑山的波德戈里察以及东加勒比的圣文森特和格林纳丁群岛、男男性行为者、女性性工作者和注射吸毒者为例，描述了如何利用形成性研究来规划、实施和预测RDS调查的结果，并为开展形成性研究为RDS调查做准备提供了一个针对RDS的问题模板。我们概述案例研究，以说明形成性研究如何帮助研究人员确定RDS方法是否适合特定人群和社会文化背景，并决定导致成功研究结果的实施细节。
Respondent-driven sampling (RDS) is widely adopted as a method to assess HIV and other sexually transmitted infection prevalence and risk factors among hard-to-reach populations. Failures to properly implement RDS in several settings could potentially have been avoided, had formative research been conducted. However, to date there is no published literature addressing the use of formative research in preparing for RDS studies. This paper uses examples from Banja Luka, Bosnia and Herzegovina; Bangkok, Thailand; Podgorica, Montenegro; and St Vincent's and Grenadine Islands, Eastern Caribbean; among populations of men who have sex with men, female sex workers, and injecting drug users to describe how formative research was used to plan, implement, and predict outcomes of RDS surveys and to provide a template of RDS-specific questions for conducting formative research in preparation for RDS surveys. We outline case studies to illustrate how formative research may help researchers to determine whether RDS methodology is appropriate for a particular population and sociocultural context, and to decide on implementation details that lead to successful study outcomes.
