目的：以实证方式评估受访者驱动抽样 (RDS) 招募方法，该方法。方法：2005 年，国家 HIV 行为监测系统使用 RDS 在西雅图地区招募了 370 名注射吸毒者 (IDU) (NHBS-IDU1)。我们将 NHBS-IDU1 对参与者的居住地区、年龄、种族、性别和最常注射药物的估计值与之前两项调查（RAVEN 和 Kiwi 研究）的相应数据以及 2001 年至 2005 年报告的新诊断出的艾滋病毒/艾滋病患者进行了比较。 结果：与其他数据源的参与者 (22%-25%) 相比，估计 NHBS-IDU1 人口更有可能居住在西雅图市中心 (52%)，年龄超过 50 岁（29% vs. 5%-10%），并报告多个种族（12% vs. 3%-5%）。 NHBS-IDU1 人群的年龄和种族分布与使用市中心针具交换中心的人相似。对 NHBS-IDU1 中跨群体招募频率的检查表明，不同居住地区、种族和最常注射的药物之间的招募存在障碍。结论：NHBS-IDU1 与其他数据源之间年龄和居住地区的显着差异表明，RDS 可能尚未访问西雅图地区注射网络的整个宇宙。需要进一步的经验数据来指导 RDS 生成的样本的评估。安流行病学 2010；20：159-167。 (C) 2010 Elsevier Inc. 保留所有权利。
PURPOSE: To empirically evaluate respondent-driven sampling (RDS) recruitment methods, which. have been proposed as an advantageous means of surveying hidden populations.METHODS: The National HIV Behavioral Surveillance system used RDS to recruit 370 injection drug users (IDU) in the Seattle area in 2005 (NHBS-IDU1). We compared the NHBS-IDU1 estimates of participants' area of residence, age, race, sex, and drug most frequently injected to corresponding data from two previous surveys, the RAVEN and Kiwi Studies, and to persons newly diagnosed with HIV/AIDS and reported from 2001 through 2005.RESULTS: The NHBS-IDU1 population was estimated to be more likely to reside in downtown Seattle (52%) than participants in the other data sources (22%-25%), be older than 50 years of age (29% vs. 5% -10%), and report multiple races (12% vs. 3%-5%). The NHBS-IDU1 population resembled persons using the downtown needle exchange in age and race distribution. An examination of cross-group recruitment frequencies in NHBS-IDU1 suggested barriers to recruitment across different areas of residence, races, and drugs most frequently injected.CONCLUSIONS: The substantial differences in age and area of residence between NHBS-IDU1 and the other data sources suggest that RDS may not have accessed the full universe of Seattle area injection networks. Further empirical data are needed to guide the evaluation of RDS-generated samples. Ann Epidemiol 2010;20:159-167. (C) 2010 Elsevier Inc. All rights reserved.
