T4

Wave 4 of the Middle Childhood Cohort consisted of an online questionnaire and a home visit in which participants were observed while performing several tasks. Additionally, physiological samples were taken (e.g., hair samples). Participants were also asked to take measurements on their own at home for several days after the home visit.
