The purpose of this research is to apply social and behavioral science methods to the interdisciplinary investigation of HIV/AIDS to improve its understanding, prevention, and treatment and improve the quality of life of persons living with HIV/AIDS.

The Core supported 202 users in 2007 compared to 39 users in 2006 - where 42% of users were CFAR investigators in 2007 versus 12.5% in 2006. Scientific discoveries and public health relevance include: Behavioral/epidemiological research involving discordant couples in Zambia led to important insights into HIV transmission; research on injection drug users in China led to HIV prevention policy changes; effective sexual risk reduction strategies among adolescents have been developed to prevent future HIV transmission; motivational readiness guide effective sexual risk reduction interventions; first behavioral treatment for injection drug use and HIV risk reduction effectively transported to Ukraine; and unique barriers to HIV/AIDS treatment were discovered among rural African American women.
