NLSY Kinship Links: Reliable and Valid Sibling Identification

项目描述（由申请人提供）：该项目旨在利用复杂的数据管理方法开发新的NLSY亲属关系文件，这些文件将对人口统计学、发育学和行为遗传学研究人员以及更广泛的社会/行为科学研究人员具有广泛的价值。我们建议从两个国家纵向调查数据库中新获得的亲属关系信息中创建数据文件，一个是1979年全国青年纵向调查数据（NLSY79, 1979年14-22岁青少年的概率样本），另一个是全国青少年纵向调查数据（NLSYC，对NLSY79中女性所生的所有亲生子女的调查）。我们将使用NLSY79和NLSYC创建兄弟对文件和多级文件。我们在过去三个美国国立卫生研究院资助的项目中使用隐性亲属关系创建亲属关系链接文件的广泛背景为我们提供了独特的经验和才能来开发这些文件，将它们分发给研究团队，并提供技术支持，以促进它们在应用研究环境中的使用。这一努力的成果将是制作四种不同格式的亲属关系档案，一个可用于查阅这些档案的网络系统，并培训一名新的年轻研究人员，为使用这些档案提供技术支助。我们将这些文件的价值记录给数十个，甚至数百个使用NLSY数据集进行家庭研究的研究团队。

DESCRIPTION (provided by applicant): The project is designed to use sophisticated data management methods to develop new NLSY kinship linking files, which will be broadly valuable to demographic, developmental, and behavior genetic researchers, as well as to broader social/behavioral science researchers. We propose to create data files from newly available kinship information in two of the National Longitudinal Survey databases, the National Longitudinal Survey of Youth 1979 data (the NLSY79, a probability sample of adolescents aged 14-22 in 1979), and the National Longitudinal Survey of Youth Children data (the NLSYC, a survey of all biological children born to females in the NLSY79). We will create sibling pair files and multi-level files using the NLSY79 and the NLSYC. Our extensive background creating kinship linking files using implicit kinship links in the three past NIH-funded projects provides us unique experience and talent to develop these files, to circulate them to research teams, and to provide technical support to facilitate their use in applied research settings. The product of this effort will be the production of four kinship link files in a variety of formats, a web-based system available to access the files, and training of a new young researcher to provide technical support in the use of these files. We document the value of these files to dozens, and potentially hundreds, of research teams who conduct family research using the NLSY datasets. PUBLIC HEALTH RELEVANCE: This project involves filling in some critical data gaps in the National Longitudinal Survey of Youth (NLSY79 and NLSY-Children) data, to support research being conducted on many NLSY health behaviors by research teams all over the world. These are both datasets based on family/sibling designs, which can be used to study family influences on health behaviors from many perspectives. But the general "sibling" category is not informative as to type of sibling. Recently, new survey questions have been added, which can help us distinguish the sibling type for the over 12,500 respondents in the NLSY79 survey, and the over 13,000 children in the NLSY-Children survey. We will develop sibling links to distinguish between identical twins, fraternal twins, full, half, and adoptive siblings so that research can be conducted by demographic, developmental, and behavior genetic researchers who focus on family studies.
