Extreme Binge Drinking during the Transition to Adulthood
R01 AA023504
Role: Co-Investigator

This project will use existing national prospective data from Monitoring the Future (MTF) to examine the development of extreme binge drinking (i.e., consuming 10 or 15 or more drinks in a row) across young adulthood. Specific aims are to (1) examine how extreme binge drinking varies based on patterns of college enrollment and attainment, (2) document normative age-related changes in extreme binge drinking across young adulthood, and the extent to which they vary based on social role statuses and demographic indicators and are associated with trajectories of other substance use, and (3) investigate concurrent associations between reasons for drinking and extreme binge drinking behaviors.

Neurodevelopmental Pathways in Adolescent Health Risk Behavior
R01 HD075806
Keating (PI)
6/2014 – 5/2019
Role: Co-Investigator

The primary aim of this research is to understand the behavioral, cognitive, and neural bases of risk taking, through integrated analyses of age differences, developmental trajectories, and individual differences in psychosocial, neurocognitive and neural imaging assessments.

Building on Bridging the Gap: Environmental Influences on Teen Substance Use 
R01 DA032843
Cavazos-Rehg (PI)
08/2012 – 07/2017
Role: Co-Investigator

This study will provide an in-depth investigation of the processes through which school-based and state-level penalties for adolescent substance use behaviors reduce the substance use behaviors they target. We will further account for community-level exposure to anti-tobacco/drug media campaigns that are designed to also influence adolescent substance use behaviors.

Developmental Models of High-Risk Alcohol Use & Social Roles in Young Adulthood
R01 AA022087
Lee (PI)
2/2014 – 1/2019
Role: Co-Investigator

The long-term objectives of the proposed research are to extend prior research by taking a finer-grained approach with monthly assessments to 1) understand the twists and turns in drinking as they happen as a function of changes in roles and contexts in real time, how different characteristics of social roles influence these relationships, and whom may be most at risk (i.e., moderators of these associations) and 2) test and extend current developmental models of health risks. Understanding how YAs navigate different and simultaneous role transitions and identifying when and for who risk for use and consequences is at its peak can inform interventions by identifying potential mechanisms and optimal timing.

Monitoring the Future: Drug Use and Lifestyles of American Youth
R01 DA001411
Johnston (PI)
8/2012 – 4/2017
Role: Co-Investigator

Monitoring the Future provides the nation with annual indicators of the use of licit and illicit drugs, and related attitudes and beliefs. MTF is an ongoing epidemiological and etiological research and reporting project begun in 1975. In addition to being a basic research study, MTF has become one of the nation’s most relied upon sources of information on emerging trends in illicit drug, alcohol, and tobacco use among American adolescents, college students, and young and middle-aged adults. Nationally representative samples of 8th-, 10th-, and 12th-grade students (about 47,000 students in 400 schools per year) will be surveyed annually from 2013 to 2017.

Monitoring the Future: A Cohort-Sequential Panel Study of Drug Use, Ages 19–55
R01 DA016575
Johnston (PI)
8/2012 – 4/2017
Role: Co-Investigator

An ongoing series of cohort-sequential panel studies to examine changes in substance use and related factors across the life course and across historical period, using large nationally representative samples of high school graduates, from the end of high school through age 55. The study examines social and environmental factors and processes, including life-course transitions that may explain change. The target samples are drawn randomly from graduating classes of high school senior participants from the Monitoring the Future surveys.

State Medical Marijuana Laws, Attitudes and Adolescent Marijuana use in the MTF
R01 DA034244
Hasin (PI)
8/2012 – 7/2017
Role: Co-Investigator

The goal of the proposed research is to examine the effects of medical marijuana legislature on adolescent drug use attitudes and behaviors. The proposed study will involve analyses of Monitoring the Future (MTF) data to investigate the relationship between state medical marijuana laws and adolescent marijuana use, incorporating additional state-level variables from other sources.

Dynamic Links Between Risk Factors, Substance Use and Consequences: Ages 18-35
R01 DA037902
Patrick (PI)
4/2015 – 12/2018
Role: Co-Investigator

This project will move the field toward examining developmental changes in the salience of risk factors across the life course and toward documenting the mechanisms through which long-term substance use consequences emerge. Results will advance our understanding of substance use behaviors with critical health impacts, and will inform the development of interventions that take into account individual behaviors, risk factors, and social roles to find strategies for reducing the negative consequences of drug use in young adulthood.

Examining Developmental, Contextual, and Historical Effects of Civic Engagement during the Transition to Adulthood: An Integrative Interdisciplinary Approach
Spencer Grant #201500138
4/2015 – 3/2018
Wray-Lake (PI)
Spencer Foundation
Role: Co-Investigator

Using nationally representative longitudinal cohort sequential data from Monitoring the Future, this project aims to (1) describe complex, meaningful patterns of developmental change in multiple forms of civic engagement (i.e., social responsibility, volunteering, political actions), (2) identify experiences in high school and across young adulthood that predict developmental change in civic engagement, and (3) investigate variations in developmental patterns and correlates of civic engagement across social groups (e.g., socioeconomic status, ethnicity) and three decades of historical cohorts.

ABCD-USA Consortium: Research Project
U01 DA041106
9/2015 – 5/2020
Role: Co-Investigator

This proposed research project will uncover neural correlates of distinct risk pathways to adolescent substance use and identify temporal relationships between brain maturation, substance use and psychopathology.
