Network-based study design, statistical, and modeling solutions for HIV among populations that use illicit substances: Informing interventions and policy in real-world settings using existing data

The award supports research to develop and apply new statistical and modeling methods to evaluate the spillover effects of HIV interventions among marginalized populations, particularly young black men who have sex with men in Chicago. It involves secondary data analysis and agent-based modeling to improve HIV prevention strategies.

Description

This project aims to develop new methodologies for evaluating spillover effects of HIV interventions in marginalized populations, with a focus on network-based studies and agent modeling. The objective is to evaluate the spillover of HIV interventions among marginalized populations using secondary data analyses and simulation approaches, providing new insights about spillover in network studies in Chicago, Illinois. The project will develop sample size and power formulas, causal methods addressing network dependence and missing data, and conduct pre-deployment evaluation of spillover for HIV interventions including PrEP peer change intervention and PrEP delivery.
