Research on adolescent development and relationships (young cohort)

The RADAR Young study (RADAR-Y) is a population-based prospective cohort study in which adolescents are followed from age 12 to 18 years. RADAR-Y focuses on the development of (1) adolescent parent and peer relationships, (2) personality and identity, (3) psychopathology and delinquency, (4) substance use, and (5) academic achievement. RADAR-Y has a full family design: 497 adolescents, their parents, a sibling and a friend participate. Families are followed for six years. Each year a full family assessment and three internet assessments (3 month interval) are conducted. All family members and the friend participate in the full family assessment. In the internet assessments the adolescent, the mother, and friend fill out questionnaire data during five consecutive days within one week. Outcome data are collected at each assessment. Additionally, reciprocal reports on family relationships (round robin design) are collected from all family members at each annual assessment. During internet assessments, data on relationship quality are collected each day. In addition, a subsample participated in a lab assessment including (among other things) the Public Speaking Task and Facial Empathy Task. This assessment took place around the fifth annual wave. **ATTENTION: To request this data, please follow the instructions in file 5.

RADAR青年研究（RADAR-Y）是一项基于人群的前瞻性队列研究，追踪对象为12至18岁的青少年。该研究聚焦五大研究方向：(1) 青少年与父母及同伴的关系发展；(2) 人格与身份认同形成；(3) 精神病理与偏差行为；(4) 物质使用情况；(5) 学业成就。

RADAR-Y采用完整家庭研究设计，共计497名青少年及其父母、一名兄弟姐妹与一名好友参与本研究。研究追踪周期为六年，每年开展一次全家庭评估，同时每间隔三个月开展三次互联网评估。全家庭评估需所有家庭成员及受邀好友参与；互联网评估则要求青少年、母亲与好友在一周内的连续五天完成问卷填报。

每次评估均会收集结局数据。此外，在每年度的评估中，所有家庭成员均需填写家庭关系互惠报告（循环设计，round robin design）。在线上评估期间，每日都会采集关系质量相关数据。另有子样本参与了实验室评估，该评估约在第五个年度随访波次开展，内容包含公共演讲任务与面部共情任务等。
