ResearchProjects

There is an urgent need for new research approaches to advance intervention science. This project employed a new, potent, and innovative research methodology, the Multiphase Optimization STrategy (MOST), a framework for developing highly efficacious, efficient, scalable, and cost-effective interventions. This study recruited a large population of African American/Black and Latino persons living with HIV/AIDS (PLHA) in the U.S. who are not sufficiently engaged in HIV primary care and not taking antiretroviral therapy (ART). The study addressed a vulnerable population of PLHA, including critically important subpopulations of men who have sex with men (MSM) and substance users; it developed an efficient and cost effective intervention to increase engagement along the HIV care continuum for these vulnerable groups.
