“…Respondent-driven sampling is a form of snowball sampling that gives financial incentives for recruiting others into the study (Heckathorn, 1997;Johnston & Sabin, 2010;Wang et al, 2005). In the process, a researcher first recruits a small number of 'seed' subjects.…”

Sampling is central to the practice of qualitative methods, but compared with data collection and analysis, its processes are discussed relatively little. A four-point approach to sampling in qualitative interview-based research is presented and critically discussed in this article, which integrates theory and process for the following: (1) Defining a sample universe, by way of specifying inclusion and exclusion criteria for potential participation; (2) Deciding upon a sample size, through the conjoint consideration of epistemological and practical concerns; (3) Selecting a sampling strategy, such as random sampling, convenience sampling, stratified sampling, cell sampling, quota sampling or a single-case selection strategy; and (4) Sample sourcing, which includes matters of advertising, incentivising, avoidance of bias, and ethical concerns pertaining to informed consent. The extent to which these four concerns are met and made explicit in a qualitative study has implications for its coherence, transparency, impact and trustworthiness.

“…8,10,11 While RDS has been shown to be efficient in recruiting participants (i.e., in both effectiveness and speed at recruiting), 9,14,16 its promise of yielding representative samples has not always been supported or achieved in research practice. 12,14,17,18 Several difficulties have been identified in implementing RDS, including the possibility that reliance on incentives could motivate individuals to participate in a study even if they do not meet eligibility criteria. For example, individuals could present themselves as men who have sex with men, when in fact they may not actually have ever had sex with another man.…”

What Makes a Respondent-Driven Sampling “Seed” Productive? Example of Finding At-Risk Massachusetts Men Who Have Sex with Men

et al. 2010

Several recent studies have sought to elaborate upon the applicability and validity of respondent-driven sampling (RDS) to find hard-to-reach samples in general and men who have sex with men (MSM) in particular. Few published studies have elucidated the characteristics associated with initial RDS participants ("seeds") who successfully recruited others into a study. A total of 74 original seeds were analyzed from four Massachusetts studies conducted between 2006 and 2008 that used RDS to reach high-risk MSM. Seeds were considered "generative" if they recruited two or more subsequent participants and "non-generative" if they recruited zero or one participant. Overall, 34% of seeds were generative. In separate multivariable logistic regression models controlling for age, race, health insurance, HIV status, and the study for which the seed was enrolled, unprotected anal sex in the past 12 months [adjusted odds ratio (AOR)=6.68; 95% confidence interval (95% CI)=1.27-35.12; p=0.03], cocaine use during sex at least monthly during the past 12 months (AOR=8.81; 95% CI=1.68-46.27; p=0.01), and meeting sex partners at social gatherings (AOR=7.42; 95% CI= 1.58-34.76; p=0.01) and public cruising areas (AOR=4.92; 95% CI=1.27-19.01; p= 0.02) were each significantly associated with increased odds of being a generative seed. These findings have methodological and practical implications for the recruitment of MSM via RDS. Finding ways to identify RDS seeds that are consistently generative may facilitate collecting a sample that is closer to reflecting the MSM who live in all of the communities in a given location or study sample.

CONTEXTO: Os ambientes recreativos noturnos têm conquistado, na atualidade, um protagonismo crescente na vida juvenil, determinando estilos de vida, normalizando o consumo recreativo de álcool/drogas e a adoção de outros comportamentos de risco. OBJETIVO: Delinear o perfil dos jovens portugueses que frequentam ambientes recreativos noturnos e determinar a prevalência de comportamentos violentos relacionados com variáveis sociodemográficas, consumo de álcool e drogas e envolvimento nas atividades recreativas noturnas. METODOLOGIA: Entrevista de 1346 jovens (idade média = 22,49 anos) frequentadores de ambientes recreativos noturnos, de ambos os sexos, em 10 cidades portuguesas, utilizando uma variação da Respondent-driven sampling, entre 2007 e 2010. RESULTADOS: Verificou-se que existe uma relação positiva entre comportamentos violentos, consumo de álcool e drogas e a participação dos jovens na vida recreativa noturna. Conclusões: Sugere-se que a implementação de medidas preventivas neste contexto atenda às características dos jovens apresentadas neste estudo como preditoras de comportamentos violentos.
