This research project will provide an empirical investigation into the realities of respondent driven sampling (RDS) data collection. RDS is a new method for sampling rare or hidden populations. The method starts with the members of the target population and traces their social networks as well as the networks of those to whom they are connected. Although this method is growing in popularity, there is a scarcity of publicly available RDS datasets. As a result, methodological assessments of RDS are very limited. This research project will conduct a theory-drive methodological assessment of RDS. The project will provide a platform to develop design features for RDS studies that minimize potential errors and violations of critical assumptions. By developing appropriate inference strategies, rare or hidden populations will be more fully represented in the data collected by RDS methods. Absent these types of examinations, behavioral and social science data collected through RDS runs the risk of mischaracterizing rare or hidden populations in unknown ways. To the extent that these data inform public policies, rare or hidden populations may benefit from this research. New datasets will be generated and made publicly available to promote methodological research beyond this project.This research project will conduct an empirical assessment RDS within the Total Survey Error (TSE) framework. TSE is a framework in survey methodology that allows for the systematic examination of errors. This project seeks to improve current RDS data collection and inference practices by examining sampling productivity, error properties, and replicability. The investigators will collect data on two rare populations in Los Angeles County for which external probability-based sample data are available. The probably-based data will be used as "gold standards" against which estimates from the RDS collected data will be compared, providing a unique opportunity to assess RDS not only as a sampling method but also as a data collection method. The data sets will empirically inform a simulation study that will examine the effects of various network structures and response propensities on sampling productivity and inferential errors. The project is supported by the Methodology, Measurement, and Statistics Program and a consortium of federal statistical agencies as part of a joint activity to support research on survey and statistical methodology.

本研究将提供一个实证调查的受访者驱动抽样（RDS）数据收集的现实。 RDS是一种新的稀有或隐藏种群抽样方法。 该方法从目标人口的成员开始，追踪他们的社交网络以及与他们有联系的人的网络。 虽然这种方法越来越受欢迎，但公开可用的RDS数据集却很稀缺。 因此，RDS的方法学评估非常有限。 本研究将对RDS进行理论驱动的方法学评估。 该项目将提供一个平台，为RDS研究开发设计功能，最大限度地减少潜在的错误和违反关键假设。 通过制定适当的推理策略，罕见或隐藏的人口将更充分地体现在RDS方法收集的数据。 如果没有这些类型的检查，通过RDS收集的行为和社会科学数据有可能以未知的方式错误描述罕见或隐藏的人群。 在一定程度上，这些数据为公共政策提供了信息，罕见或隐藏的人群可能会从这项研究中受益。 新的数据集将被生成并公开提供，以促进本项目以外的方法学研究。本研究项目将在总调查误差（TSE）框架内对RDS进行实证评估。 TSE是调查方法中的一个框架，可以系统地检查错误。 这个项目旨在通过检查抽样生产率，错误属性和可复制性来改善目前的RDS数据收集和推理实践。 研究人员将收集洛杉矶县两个罕见人群的数据，这些人群的外部基于概率的样本数据可用。 基于概率的数据将被用作“黄金标准”，与RDS收集的数据进行比较，提供了一个独特的机会来评估RDS，不仅作为一种抽样方法，而且作为一种数据收集方法。 这些数据集将根据经验为模拟研究提供信息，该研究将检查各种网络结构和响应倾向对抽样生产力和推理错误的影响。 该项目得到了方法、测量和统计方案以及联邦统计机构联合会的支持，作为支持调查和统计方法研究的联合活动的一部分。
