TRAILS

TRAILS is a prospective cohort study, which started in 2001 with population cohort and 2004 with a clinical cohort (CC). Since then, a group of 2500 young people from the Northern part of the Netherlands has been closely monitored in order to chart and explain their mental, physical, and social development. These TRAILS participants have been measured every two to three years, by means of questionnaires, interviews, and all kinds of tests. By now, we have collected information that spans the total period from preadolescence up until young adulthood. One of the main goals of TRAILS is to contribute to the knowledge of the development of emotional and behavioral problems and the (social) functioning of preadolescents into adulthood, their determinants, and underlying mechanisms.

TRAILS是一项始于2001年的前瞻性队列研究，其初始阶段涵盖人口队列，并于2004年引入临床队列（CC）。自那时起，2500名荷兰北部地区的年轻人被紧密跟踪监测，以描绘并阐释其心理、生理及社会发展的轨迹。这些TRAILS参与者每隔两到三年就会接受问卷调查、访谈及各类测试。迄今为止，我们已收集了涵盖从青春期前期至青年成熟期整个阶段的详细信息。TRAILS的主要目标之一是丰富对青春期前期儿童在成年期情感和行为问题的发展、（社会）功能及其决定因素和潜在机制的认知。
