Year 15 Survey Components
Data collection for the Year 15 follow-up wave began in February 2014, and is projected to end in the spring of 2017. It will roll out in four waves, and include parent interviews, teen interviews and home visits. The target sample for the parent and teen interviews is 3,600 families. The in-home survey will be conducted with a subset of approximately 1,000 teens.
The aims of this wave of data collection are to update information on children’s health and development and collect new data on health and health risk behavior, school performance, and anti- and pro-social behavior; update information on contextual factors, including families, neighborhoods, schools and peers, including retrospective data on family experiences since the last interview; and collect saliva samples from 3,600 teens to be used for future methylation analysis.
Core Parent Interview: 1-Hour Telephone Survey
This survey contains a short section to confirm the primary caregiver’s (PCG) relationship to the child and the amount of time living with the child (Section A), and collects information on the teen's health and behavior (Section B) and education (Section C), family life and parenting (Section D), household structure and family relationships (Section E), non-residential biological fathers (Section F), co-residential biological father or partner (Section G), PCG health and behavior (Section H), social environment and informal support (Section I), housing and programs (Section J), and parent’s education, employment and income (Section K).
Teen Interview: 1-Hour Telephone Survey
This survey contains a short series of confirmation questions about the youth’s living arrangement and introduction (Section A), and collects information on the focal teen’s education (Section B), family relationships (Section C), neighborhood (Section D), health and health behavior (Section E). This survey contains questions used in other national longitudinal studies, including the National Longitudinal Study of Adolescent Health (ADD HEALTH), National Longitudinal Study of Youth (NLSY), and the Panel Study of Income Dynamics (PSID).
Saliva samples for genetic analysis will be collected from teens via mail or during the in-home survey.
During Home Visits, interviewers will take physical measurements of the teen’s height, weight and waist circumference. The Martin and Massey New Immigrant Survey Skin Color Scale will be completed through interviewer observation of the teen. Additionally, at the end of the home visit, the interviewer will complete observations of the neighborhood, home, teen’s appearance and behavior, primary caregiver's behavior, and interactions with the interviewer and teen.
Researchers at Stony Brook University, Penn State University and Brigham and Women's Hospital are collecting data in order to investigate the biopsychosocial determinants of adolescent sleep. As part of this study, teens receiving the Home Visit will also be asked to complete a one-week sleep, physical activity, and multimedia exposure time-use diary. On each of the seven days following the Home Visit, teens will complete a 10-minute web-based survey collecting information on that day’s sleep habits, eating, exercise, and mood. Furthermore, they will be asked to provide actigraphy data during that one-week period immediately following the Home Visit. These teens will be asked to wear two actigraphs simultaneously, one on the hip to collect physical activity data, and one on the wrist to collect sleep data.
Additionally, University of Michigan researchers will assess approximately 300 families in two sample cities, studying how stress and poverty impacts underlying biological mechanisms (such HPA axis and amygdala function) and gives rise to symptoms such as anxiety and depression. Families in this study will participate in a battery of activities at University of Michigan Functional MRI and Psychology labs, including a MRI session, saliva sample collection, cortisol measurement, structured clinical interviews, and tasks measuring reward learning and attention bias, as well as observational behavior measurement. An additional follow-up phone interview will be conducted in two years with these teens. This project will identify how adverse environments sculpt brain, physiological and cognitive-affective development and give rise to psychopathology in adolescence.
