Assessment of Random Recruitment Assumption in Respondent-Driven Sampling in Egocentric Network Data.
BACKGROUND One of the key assumptions in respondent-driven sampling (RDS) analysis, called "random selection assumption," is that respondents randomly recruit their peers from their personal networks. The objective of this study was to verify this assumption in the empirical data of egocentric networks. METHODS We conducted an egocentric network study among young drug users in China, in which...
متن کاملModelling the Effect of Differential Recruitment on the Bias of Estimators for Respondent-Driven Sampling
Respondent Driven Sampling has previously been modelled as a random walk on a network. In this document we show that this model can be used to encompass within-group differential recruitment, and examine the implications for bias of several common estimators.
متن کاملRandom Walks on Directed Networks: Inference and Respondent-driven Sampling
Respondent driven sampling (RDS) is a method often used to estimate population properties (e.g. sexual risk behavior) in hard-to-reach populations. It combines an effective modified snowball sampling methodology with an estimation procedure that yields unbiased population estimates under the assumption that the sampling process behaves like a random walk on the social network of the population....
متن کاملRespondent Driven Sampling
Respondent driven sampling (RDS) is a network sampling technique typically employed for hard-to-reach populations (e.g. drug users, men who have sex with men, people with HIV). Similar to snowball sampling, initial seed respondents recruit additional respondents from their network of friends. The recruiting process repeats iteratively, thereby forming long referral chains. Unlike in snowball sa...
متن کاملAssessing respondent-driven sampling.
Respondent-driven sampling (RDS) is a network-based technique for estimating traits in hard-to-reach populations, for example, the prevalence of HIV among drug injectors. In recent years RDS has been used in more than 120 studies in more than 20 countries and by leading public health organizations, including the Centers for Disease Control and Prevention in the United States. Despite the widesp...
