REACH Webinar on Respondent-Driven Sampling April 4
Respondent-driven sampling (RDS), combines “snowball sampling” (getting individuals to refer those they know, these individuals in turn refer those they know and so on) with a mathematical model that weights the sample to compensate for the fact that the sample was collected in a non-random way (www.respondentdrivensampling.org). RDS is used in survey research as a way to sample groups who are often hidden or marginalized for and has been used in several recent Canadian studies. It is quickly becoming a method utilized in HIV surveillance in various locations around the world.
Watch a 30 minutes video presentation by Dr. Greta Bauer, an Associate Professor in the Department of Epidemiology & Biostatistics at The University of Western Ontario, in which she provides us with an overview of RDS, drawing on her experience with three recent survey projects.
