Adolescent Health and Development in Context (AHDC) Study, Franklin County, Ohio, Wave 1, 2014-2016

The overarching objective of the
Adolescent Health and Development in Context (AHDC) Project is to collect multilevel,
multi-contextual data on a large sample of 1,405 youth ages 11 to 17 years in
Franklin County, Ohio. The study emphasizes the interplay of social,
psychological, and biological processes in shaping youth developmental outcomes
such as risk behavior and victimization, mental and physical health, and
educational outcomes. The study employs a prospective
cohort design in which the data on youth and caregivers were collected at two
time-points, approximately one year apart. The Wave 1 field period began in spring
2014 and was completed in summer 2016.
Wave 2 was conducted between January and December 2016. Within each
wave, participant data were collected over a weeklong period. An Entrance
Survey with both a focal youth and his or her caregiver was followed by a seven-day
smartphone-based Global Positioning System (GPS) tracking and EMA data
collection period (EMA Week), and a final Exit Survey at the end of the week.
