In May 2015 YOUth was launched: a large-scale, long-term cohort study. YOUth follows children from before birth until the age of 18. This large-scale longitudinal cohort study with repeated measurements consists of two independent but related samples from the general population.
The first entrypoint consists of 3,000 babies who are recruited through their pregnant mothers. The mothers will be tested (including 3D echo’s) at 20 and 30 weeks of pregnancy, their infants at about 5 and 10 months and at about 3 and 6 years of age.
The second entrypoint of children consists of a similar number of 8-10 year olds who are recruited through schools. They will be tested at about 9, 12 and 15 years of age.
In both groups, at each visit behavioral development and brain development is measured using EEG/ERP (in the infants and young children), structural and functional MRI (in the school age children), eye-tracking, behavioral and computer tasks. The focus of the tasks is on behavioral control and social competence, and aimed to track longitudinal changes therein. Parent-child interaction and IQ are measured as well.
In addition, both questionnaires and biological material are obtained from the parents.
