Also known as the Adolescent Health and Development in Context (AHDC) study, the focus of this study was adolescent health and behavior, including real-time location and activities of adolescents (ages 12-16). Each participating youth was required to have one parent/caregiver participate with them. Each parent/caregiver was interviewed and provided information about the household, how the parent/caregiver spent their days and how they thought their youth spent their days. Activity locations were tracked as part of the study.


During the youth interview, the interviewer asked about their friends, where they spent their time away from school and home, and who they spent it with. The youth participant's activity locations were also tracked, similar to the parent/caregiver. At the end of the first visit, the youth participant was assigned a smart phone to carry for seven days with GPS to track their travels and send them five daily EMA’s (environmental momentary assessment in the form of mini-surveys) with questions about their surroundings at that particular moment in time. After the week was completed, the interviewer returned for a second visit and asked additional questions about the week of activities.

Along with the interviews, both the youth and parent/caregiver completed self-administered surveys. By collecting this information via a study-provided smart phone, interviews, and surveys, the researchers hoped to get a real-time glimpse into the daily lives of adolescents.

CHRR designed and conducted The Ohio Study for Dr. Chris Browning, Professor of Sociology at The Ohio State University and Dr. Jodi Ford, OSU College of Nursing, and their colleagues. The first wave of the Ohio Study occurred in 2014, the second wave in 2016, and the third wave began at the end of 2018 and is in-progress.
