The Ohio Study



Dr. Christopher Browning, Professor, Sociology
Rank at time of award: Professor


Christopher Browning is the director of The Ohio Study, also known as The Adolescent Health and Development in Context (AHDC) project, which focuses on the impact of multiple social contexts – neighborhood, home, school, and peers – on risky behavior (including substance use and delinquency), and mental/physical health outcomes. Collecting data on a large sample of adolescents, ages 11-17 years, in Franklin County, this innovative project combines in-home surveys with a week of smartphone-collected GPS and real-time mini-survey data. For a subsample of participants, saliva and hair are also collected to analyze biological measures of stress. This research will develop our understanding of how the actual places youth go and the people with whom they interact on a daily basis influence their health and behavior. Several other IPR associates contribute to the project, including Catherine Calder, Elizabeth Cooksey, Jodi Ford, Kammi Schmeer, Dana Haynie, and research associate Beth Boettner.
