This paper describes a flexible, multi-stage, nonprobability sampling process used in a study of persons recently diagnosed as HIV-positive (PRDH). From July 2007 to June 2008, we used venue and chain-referral sampling strategies to recruit PRDH in the US. We sought equal distributions (n = 20) of eligible PRDH from four self-identified subgroups: gay or bisexual men (GBM), heterosexual men (HM), heterosexual women (HW), and male-tofemale transgender women (TGW). We categorized 30 sampling venues as websites, health clinics, or other networks. For 359 volunteer respondents, website venues proved more productive compared to health clinics and other sources. Website venues were most efficient for sampling recently diagnosed GBM and HW. Passive sampling methods were less effective in recruiting HM and TGW. Sampling approaches should be flexible and tailored to reach sub-categories within hidden populations. The sampling process itself produced valuable knowledge about social networks of hidden HIV populations.
