In Plain Sight: Sampling Hidden Populations with Adaptive Sampling Methods

Sponsor:
Hamovitch Center for Science in the Human Services, USC School of Social Work Research Clusters of Excellence
Cost:
Free
Details:

Dr. Henry Fisher Raymond, deputy director of the Center for Public Health Research at the San Francisco Department of Public Health and assistant professor of epidemiology and biostatistics at the University of California, San Francisco, will review the basic idea of sampling populations and share some of the approaches that have been used around the world to reach “hidden” populations for research. Respondent driven sampling (RDS), which is in wide use among hidden populations all over the world, will also be discussed. Additionally, Raymond will review the theoretical basis of RDS, including what biases RDS analysis corrects. Some examples of RDS analysis will be shared, and a brief introduction to the implementation of RDS studies will be provided.

Raymond has more than 15 years of experience sampling hard-to-reach populations using state-of-the-art adaptive sampling methodologies, including time location sampling and RDS.

Lunch will be provided.
