DESCRIPTION (provided by applicant): This is an application to extend the NICHD Study of Early Child Care and Youth Development (SECCYD) into its fourth phase. The SECCYD is a collaborative, prospective, longitudinal study of a cohort of 1,073 adolescents and their families, first enrolled at one month of age and studied intensively through sixth grade in Phase lll of this cooperative agreement. The primary study aims of Phase IV are (1) to investigate how earlier functioning and experiences, in concert with contextual and maturational factors in adolescence, influence social relationships, health, adjustment, and intellectual and academic development during middle adolescence; and (2) to extend into middle adolescence an intensive and extensive study of patterns of health and human development from infancy onward, which can be used by the broader scientific community to study a wide range of basic and applied questions. Primary data collection in Phase IV occurs when the adolescents are 15 years old, and again, at 16. At 15, a home visit occurs in which parent-adolescent interactions are videotaped and the adolescents and their parents (or parental figures) complete questionnaires and structured interviews. During lab visits at ages 15 and 16, adolescents' achievement is assessed and adolescents complete self-report measures. The age 15 data collection also includes an extensive assessment of the adolescent's cognitive functioning, cortisol reactivity, and physical activity. In addition, yearly examinations of pubertal status and health are conducted. Finally school personnel complete questionnaires and adolescents' school transcripts are coded at the end of middle school and Grade 10. These data, in concert with data from earlier Phases, will be used to test four models of developmental processes.

描述（由申请人提供）：这是一份申请，旨在将NICHD早期儿童保育和青少年发展研究（SECCYD）扩展到第四阶段。SECCYD是一项协作性的、前瞻性的、纵向的研究，研究对象是1073名青少年及其家庭，他们在1个月大的时候首次入组，并在该合作协议的第三阶段深入研究到六年级。第四阶段的主要研究目的是：(1)研究早期的功能和经历如何与青春期的环境和成熟因素相一致，影响青春期中期的社会关系、健康、适应和智力和学业发展；(2)将从婴儿期开始的健康和人类发展模式的深入而广泛的研究扩展到青春期中期，这可以被更广泛的科学界用于研究广泛的基础和应用问题。第四阶段的主要数据收集发生在青少年15岁和16岁时。15岁时，进行一次家访，父母与青少年的互动被录下来，青少年和他们的父母（或父母形象）完成问卷调查和结构化访谈。在15岁和16岁的实验室访问期间，青少年的成就被评估，青少年完成自我报告措施。15岁的数据收集还包括对青少年认知功能、皮质醇反应和身体活动的广泛评估。此外，每年进行青春期状况和健康检查。最后，学校人员完成问卷调查，并在中学和十年级结束时对青少年的学业成绩进行编码。这些数据与早期阶段的数据相一致，将用于测试四种发展过程模型。
