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.

TRAILS（追踪青少年个体生活调查，全称为TRacking Adolescents' Individual Lives Survey）是一项持续开展的多学科研究，旨在探究青少年与青年成人的心理、社会及躯体发展状况。自研究启动以来，已有超过2700名参与者在约11岁时加入队列。在超过20年的随访周期中，研究团队每2至3年便会通过问卷、访谈、测评及/或躯体测量对这些参与者进行一次评估。研究数据不仅采集自参与者本人，还涵盖其家庭成员、教师、同伴及伴侣的相关信息。TRAILS 由人口队列（TRAILS: POP）与临床队列（TRAILS: CC）两个子队列构成。自2015年起，研究团队通过子代研究项目TRAILS NEXT对参与者的子女开展数据采集与评估工作。
