Alcohol and Substance Use
CHIP alcohol and substance use research includes risk reduction interventions for injection drug users as well as interventions addressing alcohol-related HIV risk behaviors and alcohol-related obstacles to antiretroviral medication adherence in various target populations. Other lines of CHIP alcohol and substance use research involve interventions to reduce excess drinking in college students, interventions using exercise to reduce hazardous drinking behavior and drug use, and a study exploring gender differences in addictive behaviors among returning veterans. New projects in this health domain in FY13 include a laboratory-based study examining the effects of discrimination and social exclusion on the willingness of young Black and White adults to engage in risky sex and drug use, and a second study using meta-analysis to assess alcohol consumption and HIV risk behavior.
Much of CHIP’s past or present research in this domain has been internationally-based, including research performed in China, Malaysia, Russia, South Africa, Thailand, Ukraine, and Vietnam.
Additionally, CHIP’s 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, with a special focus on the adolescents who were age 10 at Wave 1 (age 26 at Wave 6) 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.
