One of the challenges in studying HIV-risk behaviors among gay men is gathering information from a non-biased sample, as traditional probability sampling methods cannot be applied in gay populations. Respondent-Driven Sampling (RDS) has been proposed as a reliable and bias-free method to recruit "hidden" populations, such as gay men. The aim of this study is to assess the feasibility and effectiveness of RDS to sample Latino gay men and transgender persons. This was carried out when we used RDS to recruit participants into a study that investigated community involvement on HIV/AIDS sexual risk behaviors among Latino gay and bisexual men, and transgender (male-to-female) persons in Chicago and San Francisco. The population coverage of RDS was then compared to simulated time-location sampling (TLS). Recruitment differences were observed across cities, but the samples were comparable. RDS showed broader population coverage than TLS, especially among individuals at high risk for HIV.

    • "Theoretically, an equilibrium state would be attained after several waves of recruitment, and unbiased statistical estimates approaching those obtained from random probability sampling would be obtained [33,35]. The RDS design is hence an improvement over the venue-based sampling method commonly used in HIV research targeting MSM [36,37]. "

    ABSTRACT: The HIV prevalence and incidence among men who have sex with men (MSM) are high. Unprotected anal intercourse (UAI) with male regular partners (RP) is an important but under-emphasized risk behavior. The current study aimed to describe the prevalence of UAI with regular partner and the associated multi-dimensional factors with UAI among MSM in Hong Kong, China. Respondent Driven Sampling method was used to recruit participants. A total of 285 participants were recruited, of whom 211 (75.1%) had had anal sex with RP in the last six months and their data were analyzed in this report. Weighed data were presented and logistic regression methods were fit. Participants' high risk behaviors in the last six months included high prevalence of having had UAI with RP (45.8%), having had non-regular male sex partners (NRP: 27.3%) and UAI with such partners (18.9%). Adjusted for socio-demographic variables, factors associated with UAI with RP included: 1) substances use prior to having anal sex (65.7% versus 43.8%; AOR =2.36; 95% CI =1.07-5.18), 2) worry that condom use symbolizes mistrust (67.9% versus 44.3% ; AOR = 2.91; 95% CI =1.19-7.10), 3) a lower perceived degree of the RP's acceptance of condom use (91.7% versus 38.3%; AOR = 22.70; 95% CI =6.20-83.10), and 4) a higher level of impulsivity (61.1% versus 35.0%; AOR =4.02; 95% C I = 1.62-9.97). Two of these four variables, substances use (ORm = 2.28, 95% CI = 1.01-5.16) and perceived lower level of RP's acceptance of condom use (ORm = 17.22; 95% CI = 5.06-58.62) were selected by the forward stepwise logistic regression model. MSM with RP in Hong Kong is subjected to high risk of HIV transmission. Risk factors of UAI are multi-dimensional and interventions need to take into account factors of structural, interpersonal and individual levels.

    • "This recruitment strategy relies on peer referral and dualincentives to recruit members of hidden populations for which a sampling frame of the entire population cannot be obtained. Previous research among Latino gay men has shown this recruitment strategy to provide larger population coverage, and thus more reliable and valid population estimates, than time-location sampling (Ramirez-Valles et al. 2005). In all, 4 invited participants and 96 referred participants completed the survey. "

    ABSTRACT: Male circumcision has received increased attention for its potential to reduce sexual transmission of HIV. Research on the acceptability of circumcision as a means of HIV prevention among men who have sex with men is limited. Men who have sex with men in Bogotá, Colombia, either participated in a focus group in which they shared information regarding their perceptions of circumcision or completed a survey that assessed circumcision experiences, attitudes, beliefs and willingness. Few participants reported they were circumcised, yet most participants reported knowing something about the procedure. Overall, attitudes towards circumcision were mixed: although circumcision was viewed as safe, it was also viewed as unnatural and cruel to babies. Beliefs that circumcision could improve sexual functioning and protect against STIs and HIV were not widely endorsed by survey participants, although focus-group participants discussed the potential impacts of circumcision on the availability of sexual partners and sexual performance. Some focus-group participants and many survey participants reported a hypothetical willingness to get circumcised if strong evidence of its effectiveness could be provided, barriers removed and recovery time minimised.

    • "Qualitative and mixed-methods researchers have developed a variety of innovative approaches to access more diverse and representative samples of hidden populations, although some degree of sampling bias and limitations to representativeness inevitably remain. We have found it most efficacious to combine strategies from a variety of sampling strategies – venue-based sampling (Arcury & Quandt 1999; Stueve et al. 2001; Kelly 2010), targeted sampling (Bluthenthal & Watters 1995; Carlson et al. 1994; Peterson et al. 2008), and respondent-driven sampling (Heckathorn 1997; 2002; Ramirez-Valles et al. 2005; Wang et al. 2005), rather than adhering strictly to one model alone. Our success in utilizing these different sampling strategies has varied. "

    ABSTRACT: Qualitative research is often conceptualized as inherently small-scale research, while larger-scale projects are often assumed to be solely the domain of quantitative researchers, The aim of this paper is to discuss qualitative research done on a comparatively larger scale. In addition to the centrality of a qualitative perspective, the research incorporates some quantitative elements into the design, data collection, and analysis. Larger-scale qualitative research shares some of the challenges and promises of smaller-scale qualitative work. However, there are additional challenges specific to the scale of qualitative research such as data overload, time constraints, and mentoring large research teams. Yet large samples can prove to be essential for enabling researchers to conduct comparative research, whether that be cross-national research or cross-cultural research.
