Population cohort
Follow Up
Questionnaires are mailed to parents of twins at ages 0, 2, 3, 5, 7, 10 and 12 years. At ages 7, 9/10 and 12 years, we also ask parents for permission to approach the twins’ teachers. At that same moment, we ask if there are any additional siblings in the family who are in elementary school and whose teachers may be approached. From age 14 onward, adolescent twins and their siblings are invited to provide self-reports (after their parents give permission), largely substituting parental for self-report form this age onward. Once they become adults, the Young NTR (YNTR) twins can opt to join the Adult NTR (ANTR).
