Katherine Karriker-Jaffe, PhD, is a scientist at PHI's Alcohol Research Group. She examines how community and cultural determinants contribute to racial/ethnic and socioeconomic disparities in alcohol and drug use and consequences. More broadly, Karriker-Jaffe's work focuses on understanding the role of neighborhood, family and individual psychosocial factors on the development of health risk behaviors.

Alcohol’s Harms to Others among US Adults: Individual and Contextual Effects

Project aims were to (1) estimate rates, sources and severity of alcohol’s harms to others (AHTO); test hypotheses about gender and other differences in AHTO; (2) examine environmental influences (e.g., urbanicity, disadvantage, alcohol access) to gain insight about preventing such harms; and (3) use study the roles of state alcohol policies (like taxes and availability) and investigate the interplay of influences on events, sources and severity of US harms.

Identifying Modifiable Influences on Alcohol Problems in High-Risk Neighborhoods

The primary aims were to develop and test a socioecological model of relapse and recovery from alcohol problems in order to describe how neighborhood, social network and individual factors independently and interactively predict relapse and recovery from alcohol problems and alcohol use disorder over time.

Individual & Community Influences on AUDs & Other Mental Health Behaviors in Mexican Americans

Goals are to develop a multilevel, bio-psychosocial-ecological model of risk and protective factors for binge drinking, alcohol use disorders (AUDs) and other mental health behaviors in Mexican American young adults (primarily second generation immigrants). The team has expertise in community studies, bio-psychosocial measures, biometrics and genetics to tackle these complex problems. PI: Katherine Karriker-Jaffe

National Alcohol Survey (NAS) Resource Core

The NAS conducts periodic surveys of alcohol use by US adults. Recent design refinements in the 2019-20 NAS include address-based sampling and recruitment to an online survey. It also include large African American and Hispanic oversamples. The team prepares analytic datasets that include geo-referenced contextual data drawn from census and other archival sources. The NAS has been conducted since the mid-1960s. Co-directors: Katherine Karriker-Jaffe, PhD and Thomas K. Greenfield, PhD

Neural Basis of Substance Use Disorders and Suicide in American Indians

The study seeks to identify neural mechanisms, as well as individual and community risk factors, for substance use disorders (SUDs) and suicide in a community sample of American Indians (AI) residing on rural reservations. We emphasize multiple risk factor pathways that emerge in the adolescent and young adult periods which can influence the development of both SUDs and suicidal behaviors. PI: Katherine Karriker-Jaffe

Social, Developmental and Genetic Epidemiology of Alcohol Use Disorders

This international, interdisciplinary team assessed effects of exposure to risk factors in the neighborhood environment, peer context and family system during different phases in the lifecourse on development, severity and social sequelae of alcohol use disorder using longitudinal population data from Sweden.
