Racial and ethnic minorities in the United States face numerous health disparities including differential patterns of substance use and a greater burden of negative consequences associated with substance use. Using experimental analogue methods and longitudinal designs, we are currently examining the impact of racism and racial/ethnic identity formation (e.g, racial/ethnic group attachment and awareness of racism) on risk taking propensity and trajectories of substance use and other health-related risk behaviors among racial and ethnic minority youth and young adults. Our research aims to identify distinct vulnerability factors in the emergence and progression of health-related risk behavior among health disparity populations, and has implications for intervention targets that are currently underutilized.

Disparities in access to evidence-based treatments encountered by racial and ethnic minority communities further contribute to health inequity. We aim to address treatment gaps through research that focuses on the availability, efficacy, and effectiveness of evidence-based treatments for substance use and co-occurring psychological conditions with underserved populations.

Our interest in disparate patterns of substance use extends to gender socialization as a socio-cultural determinant of risk. Specifically, we are interested in the extent to which feminine and masculine norms (e.g., beliefs, values, and expectations associated with gender) contribute to differential patterns of alcohol use and risky sexual behavior that have been observed among women and men.
