The Social Intervention Group (SIG) is a multidisciplinary research center at the Columbia University School of Social Work that focuses on developing and testing effective prevention and intervention approaches and disseminates them to local, national, and international communities. 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.
