Data Collection Event

3D - Mothers - Spring prekindergarten

Information was collected in cohorts 2 and 3 when children were 4 and 3 years old respectively in September 2016 and were prekindergarten in the spring of 2017 and in the spring of 2018 respectively as well. Socio-demographics, mental and physical health, resources, parenting style, couple life, family life and lifestyle were assessed through questionnaires. During the home visit, a number-to-image matching activity called Mystero was performed with a parent and filmed to code dyadic interactions. A verbal IQ estimate was obtained during the home visit. Head circumference was measured during the home visit.
