Data Collection

具体目标 数据收集项目的具体目标是： ？跟踪和定位参与第一波Add Health计划的受访者，目标是找到92%的 我们的受访者在第四波中再次接受采访。 ？开发并试行90分钟的CAPI/CASI调查工具，在笔记本电脑上进行管理， 收集物理测量和生物标本的协议和记录程序 并对采访中获得的空间数据进行地理编码。 ？进行为期两个小时的第四波个人访谈，采访最初的第一波加健康受访者 其中收集了以下数据：反映纵向和新信息的调查数据， 纵向人体测量数据、来自血斑的生物数据和血压监测器， 来自DNA的遗传数据，以及纵向空间数据的地理位置。我们的目标是85%的复试 费率。 ？作为本计划项目延续的核心数据来源，为计划和 卫星调查人员进行他们拟议的研究，以及整个科学界 当前和将来添加健康公共用户。

Specific Aims The specific aims of the Data Collection Project are to: ¿ Trace and locate respondents who participated in Wave I of Add Health with a goal of locating 92% of our respondents for re-interview in Wave IV. ¿ Develop and pilot a 90-minute CAPI/CASI survey instrument to be administered on a laptop computer, protocols for collecting physical measurements and biological specimens, and procedures to record and geocode spatial data obtained at the interview. ¿ Conduct a Wave IV two-hour personal interview with original Wave I Add Health respondents during which the following data are collected: survey data reflecting both longitudinal and new information, longitudinal anthropometric data, biological data from blood spots and a blood pressure monitor, genetic data from DNA, and geographic locations for longitudinal spatial data. Our goal is an 85% reinterview rate. ¿ Serve as the core data resource for this program project continuation, providing data for program and Satellite Investigators to carry out their proposed research, and for the entire scientific community of current and future Add Health public users.
