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

description: 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.

The Wave 1 field period began in spring 2014 and was completed in summer 2016. 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 Ecological Momentary Assessment (EMA) data collection period (EMA Week), and a final Exit Survey at the end of the week.
The Entrance Survey was collected at a preliminary in-home visit with adolescent participants and their caregivers. It included a wide range of measures across social, economic, psychological, health, and behavioral domains. Both adolescent and caregiver participants reported on geographic location of and experiences at routine activities (e.g. school, work, church, stores, relative's house).
The real-time Ecological Momentary Assessment (EMA) surveys were collected via self-administered survey on project-provided smartphones. The study phones also passively collected GPS spatial coordinates during the seven-day EMA collection period. Youth respondents were prompted up to five times a day, and asked to report on their location, network partner presence, risk behaviors, mood, surrounding social climate, and sleep patterns.
A second visit, the Exit Survey, gathered follow-up information about the EMA week. The youth completed an interactive Space-Time Budget with the interviewer to collect detailed activity data on five days - the three most recent weekdays and two weekend days. The processed GPS data results in summarized stationary and travel periods during those five days, along with activity types and network partner presence. Concurrently, caregivers completed a self-administered survey about perceptions of social climate and safety in their neighborhood and at other routine locations.
description: The Caregiver Neighborhood Data file contains variables about caregivers' opinions of their neighborhoods and neighbors.
The Caregiver Self-Administered Data file contains variables about caregivers' jobs and income, relationships, mental health, drug and alcohol use, religion, and their child's behavior and health.
The Youth Self-Administered Data contains variables about how youths see themselves and their families, their health, drug and alcohol use, opinions about school, their friends, criminal activity, and internet and social media use.
The Demographics Data contains variables about participants' race, citizenship status, education level, age, and gender.
description: Response Rates: For AHDC Wave 1, the AAPOR
Response Rate 3 is 21.3%, which is the number of completed interviews out of the total number of households either determined
or estimated to be eligible. The AAPOR Cooperation Rate 1- the number of
completed interviews out of eligible contacted households - is 88.0%.

study area is a contiguous space within the Interstate 270 loop outerbelt freeway, encompassing a majority of the city of Columbus as well as several
suburban municipalities.
The sampling frame was based on
a combination of a vendor-provided list of households in the study area with
high probability of meeting eligibility criteria and directory data from public
school districts represented in the study area. Households were mailed a letter or postcard describing the study,
followed by interviewer calls to the household to solicit participation in the
study. Once eligibility was confirmed with
the household, one randomly selected youth aged 11-17 and one primary caregiver
(English speaking) were recruited to participate in the study.
The
racial/ethnic identity of the final sample of 1,405 youth is 47% white, 38%
Black, 5% Hispanic/Latino, 8% multiracial, and 2% Asian. The sample closely
approximates the population in the study area with respect to household income
of families with children and youth racial/ethnic composition, with
the exception that the AHDC sample has a somewhat higher percent of youth who
identified as Black compared with the 2009-2013 American Community Survey (ACS)
estimates of the area.
