The Center for Behavioral Research and Services (CBRS) is a multi-function unit dedicated to psycho-social research and services related to community health and social problems. The establishment of this unit was prompted and facilitated by the 1994 merger of the California State University, Long Beach-based AIDS Research and Education Project and the Long Beach AIDS Network, a community-based HIV service organization originally founded by the City of Long Beach's Department of Health and Human Services. The overall goal of the Center is to conduct social and behavioral research on issues affecting individual and community health and well-being, and to provide related services. The initial focus of the Center has been the coordination and expansion of local HIV research and services targeting under-served populations, including injection and other drug users, their sexual partners, commercial sex workers, others at risk for HIV infection, and persons with HIV. The focus has been broadened to address other community problems and issues such as the prevention of sexually transmitted diseases.
