Because of the high cost, venue-based probability sampling of young men who have sex with men (YMSM) is largely inaccessible to social researchers. The aim of this study is to compare the feasibility of implementing geosocial networking application-based (GSNA) and venue-based prob`ability sampling of young men who have sex with men. A cross-sectional survey conducted in Los Angeles in 2017 and 2018 recruited 124 YMSM using both methods. We compared costs and hours of work for each method. Per participant, GSNA-based methods cost approximately 157 USD compared to 383 USD for the venue-based methods. For sample sizes up to 1,000, venue-based methods cost over two times more than GSNA-based methods. Findings indicate that research teams with limited resources may be able to implement probability-based recruitment by using GSNA. By lowering the cost of research and maintaining probability-based methodological rigor, GSNAs can increase the amount of social research with YMSM.

由于成本高昂，社会研究人员基本上无法获得基于地点的与男性发生性关系的年轻人的概率抽样（YMSM）。这项研究的目的是比较实施与男男性接触的年轻人基于地理社交网络应用程序（GSNA）和基于场所的概率抽样的可行性。2017年和2018年在洛杉矶进行的横断面调查使用这两种方法招募了124名YMSM。我们比较了每种方法的成本和工作时间。对于每位参与者，基于GSNA的方法的成本约为157美元，而基于场所的方法的成本为383美元。对于多达1,000个样本的样本，基于场所的方法的成本是基于GSNA的方法的两倍以上。调查结果表明，资源有限的研究团队可能可以通过使用GSNA来实施基于概率的招聘。
