Respondent-driven
Respondent-driven, in the context of research and particularly social science research, refers to a sampling method used to gather data from hidden or hard-to-reach populations. It relies on existing members of the target population (respondents) recruiting others they know who also fit the study criteria. This 'snowball sampling' technique allows researchers to access individuals who might otherwise be inaccessible, such as drug users, sex workers, or individuals with specific medical conditions. The method's success depends on accurately estimating recruitment patterns and adjusting for network size.
Respondent-driven meaning with examples
- The study employed respondent-driven sampling to reach intravenous drug users. Each participant recruited several of their peers, creating a chain of recruitment. This allowed the researchers to collect crucial data on drug use patterns and risk behaviors within a marginalized community, overcoming geographical and social barriers that a traditional survey would face.
- Researchers utilized respondent-driven sampling to study the prevalence of a rare disease. By starting with a small group known to have the condition, they were able to connect with others who had the disease through their established social networks, expanding their sample size and providing data for medical and social understanding.
- To gather data on the experiences of undocumented immigrants, the research team turned to respondent-driven sampling. It allowed them to approach a population that is wary of engaging with official institutions, facilitating in-depth interviews with participants from their trusted community networks, exploring the nuances of their lives.
- The efficacy of a new HIV prevention program was evaluated using a respondent-driven design. By leveraging social networks, they were able to recruit participants at high risk of HIV infection, increasing access to the program, and assessing the impact on behavior change among target individuals in their social environment.
