Respondent driven sampling (RDS) is widely used for HIV behavioral research among sex workers, drug users, and other hidden populations, but has had limited application in immigrant populations in the U.S. In 2010, we used RDS to recruit undocumented Central American immigrant women in Houston, Texas for an HIV behavioral survey. Beginning with three initial participants we recruited 226 women within 16 weeks. Social networks were dense and participants adopted the recruitment system with reasonable ease. Homophily scores indicated moderate within-group preference by country of origin. However, cross-group recruitment was sufficient to achieve a diverse sample that attained equilibrium for all demographic and sexual behavior characteristics. Overall, RDS was easy to implement, attained a large sample in a relatively short period of time, and reached an otherwise hidden population. Our results suggest that RDS is an effective method for recruiting undocumented Latina immigrants for HIV behavioral surveys.
应答驱动抽样（RDS）被广泛应用于性行为者、吸毒者和其他隐蔽人群的艾滋病行为研究，但在美国移民群体中的应用有限。2010 年，我们使用 RDS 方法招募了德克萨斯州休斯顿的无证中美洲移民妇女进行艾滋病毒行为调查。从最初的 3 名参与者开始，我们在 16 周内招募了 226 名女性。社交网络密集，参与者相当容易地采用了这种招募系统。同质性分数表明原籍国之间存在适度的群体内偏好。然而，跨群体招募足以获得一个多样化的样本，该样本在所有人口统计学和性行为特征方面达到了平衡。总体而言，RDS 易于实施，在相对较短的时间内获得了大量样本，并接触到了一个隐蔽的人群。我们的结果表明，RDS 是一种招募无证拉丁裔移民进行艾滋病毒行为调查的有效方法。
