The Social Intervention Group (SIG) is a multidisciplinary research center that works to design, test and disseminate effective interventions and health services to local, national, and international communities, which address the co-occurring problems of HIV, drug abuse, intimate partner violence and trauma among vulnerable populations.

Since 1990, SIG has primarily focused on intervention and prevention research on HIV, drug abuse, IPV and trauma for vulnerable populations. SIG will continue to conduct rigorous research, employing novel intervention approaches to address these co-occurring problems, and using state-of-the-art research designs and analytic methods. SIG leadership and students established the Global Health Research Center of Central Asia (GHRCCA) in 2007 to extend the SIG mission globally. SIG and GHRCCA share key leaders and faculty, and a cross cultural learning approach:  lessons learned in domestic and international projects influence each other and shape new and innovative approaches to community research design and methods.  SIG and its affiliates are currently conducting research in the United States, Central Asia, and Malaysia.
