Title: Using MOST to Optimize an HIV Care Continuum Intervention for Vulnerable Populations
Brief Summary: The present study targets the large population of persons living with HIV/AIDS (PLHA) in the U.S. who are both insufficiently engaged in HIV primary care and not taking antiretroviral therapy (ART), who are mainly African American/Black and Latino. NIH has emphasized the urgent need for new research approaches to advance intervention science, and the proposed project employs a new, potent, and innovative research methodology, the Multiphase Optimization STrategy (MOST), a framework for developing highly efficacious, efficient, scalable, and cost-effective interventions. The proposed study has the highest public health significance: it addresses a vulnerable population of PLHA, including the critically important subpopulations of men who have sex with men (MSM) and substance users; will develop an efficient and cost effective intervention to increase engagement along the HIV care continuum for these vulnerable groups; and addresses two areas highlighted in the August 2015 notice on research priorities from the NIH Office of AIDS Research (NOT-OD-15-137), namely, engaging PLHA in prevention/treatment services, and reducing HIV/AIDS-related racial/ethnic disparities.
