TRacking Adolescents’ Individual Lives’ Survey (TRAILS)
TRAILS is an ongoing, multidisciplinary study of adolescents and young adults. The study has been following a population cohort and a clinical cohort for over 20 years, during which participants have been examined every 2 to 3 years. The population cohort includes participants who were approximately 11 years, born between 1989 and 1991, and lived in the North of The Netherlands at the time of the baseline assessment in 2001/02. The clinical cohort was recruited a few years after the population cohort, in 2004, and consists of individuals who have been referred to a child psychiatric outpatient clinic in the Northern Netherlands any time before the age of 11.
