Data collection for the Year 15 follow-up wave began in February 2014, and is projected to end in late 2017. We anticipate a public data release in mid-to-late 2018.
Data collection rolled out in four waves, and includes 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.
