Modeling Mechanisms of Human Immunodeficiency Virus and Sexually Transmitted Infections Contraction Among Serodiscordant Couples

This dissertation seeks to incrementally explain the impact of individual, interpersonal, and environmental levels of risk upon HIV/STI incidents among heterosexual African American serodiscordant couples residing in four metropolitan cities. Using archival data from a cluster-RCT (Project EBAN) and governmental surveillance reports, analytic methods that can model heterogeneous pathways within and across each level of risk were used. Findings from this dissertation revealed unique patterns and pathways via which African American females in serodiscordant relationships contracted HIV/STI.
