A New Public Data Archive for the PSID Child Development Supplement

项目总结/摘要 收入动态跟踪研究（PSID）是一项具有全国代表性的样本纵向调查 1968年开始的美国家庭。1997年，PSID开始收集关于样本中儿童的广泛数据， 最初的PSID儿童发展补充计划（CDS-I）的一部分，该计划跟踪了一组PSID儿童 0-12岁。第二波是在2002/03年收集的这些儿童（CDS-II），当时他们 年龄在5-18岁之间，第三波在2007/08年（CDS-III）收集了该队列中年龄在 10-18年。到2014年，原始CDS队列中的儿童已经成年，CDS重新启动 作为正在进行的研究，计划每隔5-6年定期收集所有0-17岁儿童的数据 在PSID家庭中度过的岁月。正在进行的CDS的第一轮于2014-2015年进行，下一轮是 计划于2019-2020年。在CDS的所有浪潮中，关于儿童发展，健康和福祉的广泛数据 从儿童的主要照顾者（PCG，通常是每个儿童的母亲）和访谈中收集 年龄较大的儿童（8岁以上）。在各轮CDS中收集了各种其他信息， 包括工作日和周末的时间日记，人体测量，家庭和邻里观察， 唾液样本用于随后的遗传分析（CDS-2014）。所有这些数据都是支持- 收集和记录，并免费分发给研究界， PSID在线数据中心。在这个项目中，我们将创建一个新的CDS在线数据中心，一个公共数据存档 专门专注于CDS，并提供重要的新功能和增强功能，这将有助于 搜索者以最少的启动时间高效地使用来自CDS的数据。具体目标是 项目包括：（1）设计和建设一个新的CDS在线数据中心，提供新的和已建立的数据 用户更容易访问原始CDS和新的正在进行的CDS的所有波;（2）增强新的CDS 在线数据中心通过增加的功能，使数据用户能够轻松地合并来自Core的数据 关于儿童一生的家庭、家庭和父母特征的PSID;（3）宣传 新的CDS在线数据中心对当前和潜在数据用户的可用性。该项目是分- 对PAR-16-149“收集和记录儿童健康和人类发展数据”的答复 设置”，并直接响应NICHD在“为公众创建数据提取网络工具”方面的具体兴趣 使用数据库，例如.这个项目 将便利科学界对NICHD科学使命内的数据进行二次分析， 在NICHD支持下收集。

Project Summary/Abstract The Panel Study of Income Dynamics (PSID) is a longitudinal survey of a nationally-representative sample of U.S. families that began in 1968. In 1997 PSID began to collect extensive data on children in the sample as part of the original PSID Child Development Supplement (CDS-I), which followed a cohort of PSID children aged 0–12 years. A second wave was collected on these same children in 2002/03 (CDS-II) when they were aged 5–18 years and a third wave was collected in 2007/08 (CDS-III) for children in this cohort who were aged 10–18 years. By 2014, children in the original CDS cohort had reached adulthood, and CDS was relaunched as ongoing study in which data collection is planned at regular 5–6 year intervals on all children aged 0–17 years in PSID families. The first round of the ongoing CDS was fielded in 2014–2015, and the next round is planned for 2019–2020. In all waves of CDS, extensive data on children's development, health, and wellbeing were collected from children's primary caregivers (PCGs, typically each child's mother) and from interviews with older children (aged 8+ years). A variety of additional information was collected in all rounds of CDS, in- cluding weekday and weekend time diaries, anthropometric measurements, home and neighborhood observa- tions, and saliva samples for subsequent genetic analysis (in CDS-2014). All of these data have been pro- cessed and documented and are being distributed—free of charge—to the research community through the PSID Online Data Center. In this project, we will create a new CDS Online Data Center, a public data archive that focuses exclusively on CDS and provides important new functions and enhancements that will help re- searchers use data from CDS efficiently and effectively with minimal start-up time. The specific aims of this project are to: (1) design and construct a new CDS Online Data Center to provide new and established data users with easier access to all waves of the original CDS and the new ongoing CDS; (2) enhance the new CDS Online Data Center through added functionality that allows data users to easily incorporate data from Core PSID about children's household, family, and parent characteristics throughout their lifetimes; and (3) publicize the availability of the new CDS Online Data Center to current and prospective data users. This project is sub- mitted in response to PAR-16-149, “Archiving and Documenting Child Health and Human Development Data Sets,” and responds directly to the specific interest of NICHD in “Creating data extraction web tools for public use databases, such as…the Panel Study of Income Dynamics Child Development Supplement.” This project will facilitate secondary analysis by the scientific community of data within the scientific mission of NICHD and collected with NICHD support.
