Research Interests

Dr. Reback is a Research Sociologist; she joined the staff of Friends Research Institute in 1997. Her research focuses on the intersection of HIV risk behaviors, substance use, sexual identity and gender identity. Dr. Reback was one of the first researchers in the country to link the rise in HIV infection among gay and bisexual men to sexual risk behaviors engaged in while using methamphetamine. Dr. Reback has an extensive background in conducting community-research collaborations, evaluating behavioral treatment therapies, designing and implementing street-based intervention programs for out-of-treatment substance users, and managing large-scale HIV prevention and intervention programs. Additionally, Dr. Reback collaborates with local community-based organizations to adopt, tailor, and transfer evidenced-based interventions into public health and community settings.

Dr. Reback has served as Principal Investigator or Co-Investigator on ethnographic, intervention and epidemiological studies funded by NIDA, CSAT, CDC, CHRP (formerly UARP), California State Office of AIDS, and the City of Los Angeles. Currently, Dr. Reback is Principal Investigator of a NIDA-funded study evaluating contingency management with non-treatment seeking MSM substance users, “Voucher-based Incentives in a Prevention Setting,” a CHRP-funded study to evaluate the efficacy of contingency management for optimizing Post-exposure Prophylaxis (PEP) among stimulant-using MSM, “Optimizing Access to Non-occupational Post Exposure Prophylaxis for HIV Using Contingency Management in Stimulant-Using Men Who Have Sex with Men,” and a CDC-funded project to adapt and transfer the Safety Counts evidence-based intervention for use among high-risk transgender women, “Human Immunodeficiency Virus (HIV) Prevention Projects for Community-based Organization.” Dr. Reback recently completed a CDC-funded study assessing the feasibility and efficacy of an information technology (IT) communication intervention that utilized test-messages for reducing methamphetamine use and high-risk sexual behaviors among out-of-treatment MSM. Dr. Reback currently serves as the Director of seven County-funded contracts for high-risk MSM substance users and transgender women and two City-funded contracts. Additionally, Dr. Reback is the Executive Director of Friends Community Center (www.friendcommunitycenter.org), the FRI’s Los Angeles community site. Dr. Reback’s solid commitment to community research has led her to become a sought-after collaborator. She is currently co-investigator on a NIDA-funded study to evaluate the effectiveness of two interventions that offer to homeless, gay and bisexual men who use stimulants the hepatitis A/B vaccine to see how well each intervention encourages completion of the hepatitis A/B vaccination series (P.I.: A. Nyamathi, UCLA).

Dr. Reback’s community and policy work includes current and past membership on numerous local and national HIV/AIDS and substance abuse task forces and advisory committees. In addition to her work with Friends Research Institute, Dr. Reback is a Research Sociologist with UCLA Integrated Substance Abuse Programs (UCLA ISAP) and a Core Scientist with the UCLA Center for HIV Identification, Prevention and Treatment Services (UCLA CHIPTS).
