研究男同性恋者艾滋病毒风险行为的挑战之一是从无偏见的样本中收集信息，因为传统的概率抽样方法不能应用于男同性恋人群。响应者驱动抽样（RDS）已被提出作为一个可靠的和无偏见的方法来招募“隐藏”的人群，如男同性恋者。本研究的目的是评估RDS的可行性和有效性的样本拉丁美洲男同性恋者和变性人。我们使用RDS招募参与者参与一项研究，该研究调查了芝加哥和旧金山弗朗西斯科拉丁裔男同性恋和双性恋男性以及变性人（男性对女性）对艾滋病毒/艾滋病性风险行为的社区参与。然后将RDS的人口覆盖率与模拟时间-地点抽样（TLS）进行比较。各城市的招聘情况存在差异，但样本具有可比性。RDS比TLS显示出更广泛的人群覆盖率，特别是在艾滋病毒高风险人群中。
One of the challenges in studying HIV-risk behaviors among gay men is gathering information from a non-biased sample, as traditional probability sampling methods cannot be applied in gay populations. Respondent-Driven Sampling (RDS) has been proposed as a reliable and bias-free method to recruit "hidden" populations, such as gay men. The aim of this study is to assess the feasibility and effectiveness of RDS to sample Latino gay men and transgender persons. This was carried out when we used RDS to recruit participants into a study that investigated community involvement on HIVAIDS sexual risk behaviors among Latino gay and bisexual men, and transgender (male-to-female) persons in Chicago and San Francisco. The population coverage of RDS was then compared to simulated time-location sampling (TLS). Recruitment differences were observed across cities, but the samples were comparable. RDS showed broader population coverage than TLS, especially among individuals at high risk for HIV.
