CORE--FIELD RESEARCH AND DATA MANAGEMENT

该核心将提供项目所需的关键主题保留、数据收集、数据管理和数据分析操作。这个核心的核心功能是：-&>与参与临床研究中心的家庭和儿童保持联系--&>；安排与儿童、家长、教师和其他提供数据的人进行数据收集访问。-根据适当的标准和数据收集时间表管理研究方案。-&gt；输入、存储和分析与调查人员合作获得的数据。一个由三名实地审查员组成的小组，每人居住在参与者居住的三个社区，将接受研究方案实施方面的培训和监督。这些审查员将前往参与儿童的家中和/或学校，以获得受试者的同意，并根据三个项目的需要收集数据。这些数据将按惯例传回中央实验室，在那里它们将被输入计算机数据库并安全存储。然后，数据将分发给适当的调查人员，或由核心统计工作人员进行数据分析。

This Core will provide the critical subject retention, data collection, data management, and data analysis operations needed by the projects. The central functions of this core are to: -> maintain contact with the families and children participating in the clinical research center -> schedule data collection visits with children, parents, teachers and others providing data. -> administer the research protocols according to appropriate standards and in accord with the schedule for data collection. -> enter, store, and analyze the data obtained in conjunction with the investigators. A team of three field examiners, each living in the three communities in which the participants reside, will be trained and supervised in the conduct of the research protocols. These examiners will travel to the homes and/or schools of the participating children in order to obtain subject consent and to collect data as dictated by the needs of the three projects. These data will be routinely transferred back to the central laboratory where they will be entered in a computer database and securely stored. The data will then be disseminated to the appropriate investigators or data analysis will be performed by the Core statistical staff.
