受访者驱动抽样（RDS）为难以接触到的人群提供了一种招募策略。然而，RDS面临着后勤和理论方面的挑战，这些挑战威胁着全球环境下的效率和有效性。我们提出了对传统RDS的创新适应，以克服在招募国际旅行的男男性行为者（MSM）的大型代表性样本时遇到的障碍。“国际旅行研究告知预防”或“I-TRIP”研究采用了新颖的方法，为参与者提供了电子和纸质优惠券的选择，以推荐招募人员，并修改了二级奖励结构，从小额现金奖励到定期大额现金抽奖。还实施了分阶段转诊限制从3次增加到10次，并逐步增加70种种子。共有501名参与者参加了多达13波的增长。在选择转诊方式的参与者中，81%的人选择了电子转诊。在电子招聘的参与者中，轮到他们招聘时，90%的人选择继续使用电子推荐。电子转诊的平均登记转诊次数为0.91次，而纸质优惠券的平均登记转诊次数为0.56次。推荐滞后时间的中位数，即从招聘人员得到推荐到被推荐的人参加研究之间的时间间隔，电子推荐为20天（IQR 10-40），纸质优惠券为20天（IQR 8-58），抽奖活动为20天（IQR 10-41），小额现金奖励为33天（IQR 16-148）。招募国际旅行的男同性恋者需要最大限度地利用已知的灵活的RDS工具，同时也需要创新来提高招募效率。电子推荐成为招募这些难以接触的人群的主要优势，这些人群具有较高的社会经济地位，地理上分散且流动性强。这些改进可能会提高RDS在具有相似特征的目标人群中的表现。
Respondent-driven sampling (RDS) offers a recruitment strategy for hard-to-reach populations. However, RDS faces logistical and theoretical challenges that threaten efficiency and validity in settings worldwide. We present innovative adaptations to conventional RDS to overcome barriers encountered in recruiting a large, representative sample of men who have sex with men (MSM) who travel internationally. Novel methodological adaptations for the “International Travel Research to Inform Prevention” or “I-TRIP” study were offering participants a choice between electronic and paper coupons referrals for recruitment and modifying the secondary incentives structure from small cash amounts to raffle entries for periodic large cash prize raffle drawings. Staged referral limit increases from 3 to 10 referrals and progressive addition of 70 seeds were also implemented. There were 501 participants enrolled in up to 13 waves of growth. Among participants with a choice of referral methods, 81% selected electronic referrals. Of participants who were recruited electronically, 90% chose to remain with electronic referrals when it was their turn to recruit. The mean number of enrolled referrals was 0.91 for electronic referrals compared to 0.56 for paper coupons. Median referral lag time, i.e., the time interval between when recruiters were given their referrals and when a referred individual enrolled in the study, was 20 days (IQR 10–40) for electronic referrals, 20 days (IQR 8–58) for paper coupons, 20 days (IQR 10–41) for raffle entries and 33 days (IQR 16–148) for small cash incentives. The recruitment of MSM who travel internationally required maximizing known flexible tools of RDS while at the same time necessitating innovations to increase recruitment efficiency. Electronic referrals emerged as a major advantage in recruiting this hard-to-reach population who are of high socio-economic status, geographically diffuse and highly mobile. These enhancements may improve the performance of RDS in target populations with similar characteristics.
