密集的社交网络数据收集自2012-2013年居住在康涅狄格州哈特福德的528名注射毒品者的典型受访者驱动样本（RDS）。这个丰富的数据集使我们能够分析大量未观察到的网络节点和关系，以评估RDS估计器的常见假设。结果表明，RDS估计，如随机选择，招生概率成比例的程度，招聘发生在招聘人员的网络关系，违反了几个假设。这些问题源于对同侪征聘过程和动态过于简单化的概念化。我们发现，近一半的参与者是通过在街上分发优惠券招募的。非统一的模式发生在多个招聘阶段与招聘人员的行为（选择和达到改变，通过优惠券等）。和招募行为（接受/拒绝优惠券，未进入研究，将优惠券传递给他人）。与这些模式相关的一些因素也与艾滋病毒风险有关。
Intensive sociometric network data were collected from a typical Respondent Driven Sample (RDS) of 528 people who inject drugs residing in Hartford, Connecticut in 2012–2013. This rich dataset enabled us to analyze a large number of unobserved network nodes and ties for the purpose of assessing common assumptions underlying RDS estimators. Results show that several assumptions central to RDS estimators, such as random selection, enrollment probability proportional to degree, and recruitment occurring over recruiter’s network ties, were violated. These problems stem from an overly simplistic conceptualization of peer recruitment processes and dynamics. We found nearly half of participants were recruited via coupon redistribution on the street. Non-uniform patterns occurred in multiple recruitment stages related to both recruiter behavior (choosing and reaching alters, passing coupons, etc.) and recruit behavior (accepting/rejecting coupons, failing to enter study, passing coupons to others). Some factors associated with these patterns were also associated with HIV risk.
