Abstract Respondent driven sampling (RDS) is a sampling method designed for hard-to-sample groups with strong social ties. RDS starts with a small number of arbitrarily selected participants (“seeds”). Seeds are issued recruitment coupons, which are used to recruit from their social networks. Waves of recruitment and data collection continue until reaching a sufficient sample size. Under the assumptions of random recruitment, with-replacement sampling, and a sufficient number of waves, the probability of selection for each participant converges to be proportional to their network size. With recruitment noncooperation, however, recruitment can end abruptly, causing operational difficulties with unstable sample sizes. Noncooperation may void the recruitment Markovian assumptions, leading to selection bias. Here, we consider two RDS studies: one targeting Korean immigrants in Los Angeles and in Michigan; and another study targeting persons who inject drugs in Southeast Michigan. We explore predictors of coupon redemption, associations between recruiter and recruits, and details within recruitment dynamics. While no consistent predictors of noncooperation were found, there was evidence that coupon redemption of targeted recruits was more common among those who shared social bonds with their recruiters, suggesting that noncooperation is more likely to be a feature of recruits not cooperating, rather than recruiters failing to distribute coupons.

受访者驱动抽样中的招聘与招聘合作机制探索

摘要受访者驱动抽样（RDS）是为社交关系较深的难以抽样的人群设计的一种抽样方法。RDS从少量任意选择的参与者（“种子”）开始。种子是发放的招聘优惠券，用于从其社交网络进行招聘。招募和数据收集的浪潮一直持续到达到足够的样本量为止。在随机招募，替换抽样和足够数量的波浪的假设下，每个参与者的选择概率收敛到与他们的网络规模成正比。但是，如果招募不合作，招募可能会突然结束，导致样本量不稳定的运营困难。不合作可能会使征聘马尔可夫假设无效，从而导致选择偏见。在这里，我们考虑两项RDS研究：一名针对洛杉矶和密歇根州的韩国移民；另一项针对密歇根州东南部注射毒品者的研究。我们探讨了优惠券兑换的预测因素，招聘者与新兵之间的关联以及招聘动态中的详细信息。虽然没有找到一致的不合作的预测因素，但有证据表明，与招募者共享社会纽带的人更容易兑现目标招聘者的优惠券，这表明不合作更可能是不合作而不是招募者失败的特征分发优惠券。以及招聘动态中的细节。虽然没有找到一致的不合作的预测因素，但有证据表明，与招募者共享社会纽带的人更容易兑现目标招聘者的优惠券，这表明不合作更可能是不合作而不是招募者失败的特征分发优惠券。以及招聘动态中的细节。虽然没有找到一致的不合作的预测因素，但有证据表明，与招募者共享社会纽带的人更容易兑现目标招聘者的优惠券，这表明不合作更可能是不合作而不是招募者失败的特征分发优惠券。
