Early Childhood Behavior Questionnaire (ECBQ)

TRAILS (TRacking Adolescents' Individual Lives Survey) is an ongoing, multidisciplinary research on the psychological, social and physical development of adolescents and young adults. More than 2700 participants have participated since they were about eleven years old. For over 20 years, these participants have been examined every 2 to 3 years, through questionnaires, interviews, tests and/or physical measurements. Data was collected not only from participants, but also their family members, teachers, peers, and partners. TRAILS consists of a population cohort (TRAILS: POP) and a clinical cohort (TRAILS: CC). Since 2015, participants’ children have been measured in the offspring study TRAILS NEXT.
