This study entails longitudinal modeling of dynamic changes in relationships, alcohol and other drug use, and lifestyle over 2–3 years in early adulthood. This longitudinal research builds on existing data that involves a multiethnic sample of 999 youth and families assessed at youth age 11-12, 12-13, 13-14, 14-15, 16-17, 18-19, 22-23, and 23-24 years.

The current study includes collecting DNA to examine genetically informed ecological models of adaptation and maladaptation in the areas of work, education, family, psychological adjustment, alcohol/drug use/ abuse, antisocial and criminal behavior, and high risk sexual behavior. Investigators are including participants' romantic partners to examine early adult intimate relationship dynamics at ages 27-29 to see how these relationships affect risky behaviors, substance use, and emotional health.

This is a subaward from Arizona State University from the National Institute of Alcohol Abuse and Alcoholism. Dr. Mark Van Ryzin assumed the role of Principal Investigator following Dr. Dishion's passing in 2018.
