Adolescent Health and Development in Context

The Adolescent Health and Development in Context (AHDC) study is collecting data on a large-scale sample of youth aged 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.

Our collection of rich, multi-contextual data on youth—particularly, detailed, geo-coded data on the activity spaces of contemporary adolescents—will significantly advance research on child and adolescent well-being by providing (1) more comprehensive data on the social contexts of youth development, and (2) data of unprecedented geographic and temporal resolution with which to measure the spatial and social exposures youth experience. These data will enable more rigorous tests of hypotheses regarding the role of social contexts in youth development and facilitate application of new methodological approaches to the measurement of developmental contexts (e.g., youth communities).
