Alcohol and Substance Use
CHIP alcohol use research includes interventions addressing alcohol-related HIV risk behaviors in HIV-positive individuals and in men and women in South Africa, as well as alcohol-related obstacles to antiretroviral medication adherence. Another line of CHIP alcohol-related research involves studying the impact of an exercise regimen on college students’ hazardous drinking behavior.
CHIP substance use research comprises risk reduction interventions for injection drug users including interventions for newly released HIV-infected prisoners transitioning back into the community, and high risk HIV-negative and unknown status individuals participating in methadone maintenance drug treatment. Other CHIP research in this domain includes an intervention using exercise to reduce drug use among cocaine users and an intervention using place-based social marketing to reduce youth drug use at parties.
Additionally, CHIP’s recently-hired, renowned health psychologists Rick Gibbons and Meg Gerrard have been conducting The Family and Community Health Study (FACHS), a longitudinal study of psychosocial factors related to the physical and mental health of African American families, for more than 15 years. The largest such study conducted to date in the US, FACHS began with 900 families and has followed them across 6 waves, focusing on the adolescents, who were 10 at Wave 1 (26 at W6), and their parents. An ongoing study, FACHS examines the impact of stressors, such as racial discrimination, environmental risk, and (low) socioeconomic status (SES), as well as buffers, such as racial socialization and racial identity, on outcomes including substance use, obesity, and disease. An offshoot of the research team’s work in this area includes using experimental (lab) methods to examine the effects of discrimination and social exclusion on the willingness of young Black and White adults to engage in risky sex and drug use.
Much of CHIP’s research in this domain has been internationally-based, including research performed (not all currently active) in China, Malaysia, Russia, South Africa, Thailand, Ukraine, and Vietnam.
