Data Collection

具体目标 数据收集项目的具体目标是： 追踪和定位参与第一波添加健康的受访者，目标是定位92%的 我们的受访者在第四波重新采访。 开发和试用一个90分钟的CAPI/CASI调查工具，在笔记本电脑上管理， 收集物理测量和生物样本的协议，以及记录 并对访谈中获得的空间数据进行地理编码。 进行第四波两个小时的个人采访与原始第一波添加健康受访者在 收集以下数据：反映纵向和新信息的调查数据， 纵向人体测量数据，来自血点和血压监测器的生物数据， 来自DNA的遗传数据和用于纵向空间数据的地理位置。我们的目标是85%的重新面试 率 作为本项目延续的核心数据资源，为项目提供数据， 卫星调查员进行他们拟议的研究，并为整个科学界， 当前和将来的Add Health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.
