Internet Gaming Disorder Scale (IGD)

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（Tracking Adolescents' Individual Lives Survey，即青少年个体生活追踪调查）是一项持续开展的多学科研究，聚焦青少年与青年群体的心理、社会及躯体发育状况。自参与者约11岁起，已有超过2700人参与本研究。在超过20年的随访周期中，研究团队每2至3年便通过问卷、访谈、测评及躯体测量等方式对这些参与者进行数据采集。研究数据不仅来源于参与者本人，还涵盖其家庭成员、教师、同伴及伴侣的相关信息。TRAILS包含人群队列（TRAILS: POP）与临床队列（TRAILS: CC）两个子队列。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工作。
