目的：受访者驱动的抽样（RDS）使用长链推荐，即目标人群的成员招募其他成员。我们描述了在肯尼亚基苏木的一项性与生殖健康（SRH）混合方法研究中使用RDS的情况。方法：横断面调查的初始种子从15-19岁居住在城市非正规住区的青少年中选择。参加者可获发最多五张推荐券。结果：在4个社区中，共筛选出18个种子，发放了13489张优惠券，推荐了3381名青少年，优惠券收益率为25%。我们招募了3061名参与者，调查率为23%。中位转诊延迟时间为3天（IQR 1,7）。人口特征在三个社区的第5至第8轮招募和第4至第15轮招募之间达到平衡。结论：我们的研究表明RDS是一种可行和有效的方法来招募大量的青少年样本。虽然我们的研究侧重于性生殖健康，但许多生活在贫困城市环境中的青少年也经历了粮食不安全、住房不稳定和暴力。因此，RDS可以成为一种有价值的招募方法，用于未来的研究，以覆盖弱势青少年，并设计干预措施，解决影响这一服务不足人群的各种健康相关挑战。(c) 2022年Elsevier Inc.出版
Purpose: Respondent-driven sampling (RDS) uses long-chain referral whereby members of the target pop-ulation recruit other members. We describe the use of RDS for a mixed-methods sexual and reproductive health (SRH) study in Kisumu, Kenya.Methods: Initial seeds for the cross-sectional surveys were selected from adolescents aged 15-19 residing in urban informal settlements. Participants were provided up to five referral coupons to distribute.Results: Across four communities, 18 seeds were selected, 13,489 coupons distributed, and 3381 adoles-cents referred, yielding a 25% coupon return rate. We enrolled 3061 participants for a 23% survey rate. Median referral lag time was three days (IQR 1, 7). Demographic characteristics reached equilibrium be-tween recruitment waves 5 to 8 in three communities, and waves 7 to 15 in the fourth.Conclusions: Our study demonstrated that RDS is a feasible and efficient approach for recruiting a large sample of adolescents. Though our research focused on SRH, many adolescents residing in the impover-ished urban environments where our study was implemented also experience food insecurity, housing instability and violence. RDS can therefore be a valuable recruitment approach for future studies to reach vulnerable adolescents and design interventions that address the variety of health-related challenges that affect this underserved population.(c) 2022 Published by Elsevier Inc.
