Recruitment and Retention

招聘和保留核心的主要目的是开发和维护一批 供青少年及其父母在所有项目中使用，并确保各项目之间的科目顺畅 随着时间的推移。核心的具体职能是：1)招募18所高中参与研究 通过允许核心筛选和确定符合条件的9年级和10年级学生参加；2)保持良好 在整个研究过程中与高中的关系；3)进行知情同意和 协调各项目的IRB事宜；4)在学校对青少年进行初步筛查，以确定 有资格参加纵向研究的学生；5)招募符合条件的青少年及其家长进入 项目；6)管理和收集所有常见的纸质和铅笔问卷测量(基线至 36个月)，以及30个月大的青少年的可替宁样本；7)跟踪和定位失踪 青少年和家长的行动；8)协调主体流程和主体参与的时间 用于参与多个项目的人员；9)帮助维护来自该项目的数据流的顺畅协调 数据管理、测量和统计核心的核心；以及10)实施小组战略，以 减少研究过程中的消耗。我们将采用招聘和留住相结合的方式 从我们目前对青少年样本的工作中发展出来的程序(在这个样本中，我们已经成功地 通过18个月的跟踪，实现了所有招聘目标，并保留了90%以上的队列)， 这需要与学校、家长和对青少年敏感的程序保持良好的关系。

The primary purpose of the Recruitmcnt and Retention Core is to develop and maintain a cohort of adolescents and their parents for use in all projects, and to ensure the smooth flow of subjects across projects and over time. The specific functions of the core are to: 1) recruit 18 high schools to participate in the study by allowing the core to screen and identify eligible 9 th and 10 th graders for participation; 2) to maintain good relationships with the high schools throughout the course of the study; 3) to conduct informed consents and coordinate IRB matters across projects; 4) to conduct initial screenings of adolescents at schools to identify students eligible for the longitudinal study; 5) to recruit eligible adolescents and their parents into the projects; 6) to administer and collect all common paper and pencil questionnaire measures (baseline through 36 months), as well as cotinine samples from adolescents at 30 months; 7) to track and locate missing adolescents and parents as they move; 8) to coordinate the subject flow and timing of subject participation for those involved in more than one project; 9) to help maintain smooth coordination of data flow from this core to the Data Management, Measurement, and Statistics Core; and 10) to implement panel strategies to reduce attrition over the course of the study. We will use a combination of recruitment and retention procedures developed from our current work with an adolescent sample (in which we have successfully achieved all recruitment goals and retained more than 90% of a cohort through an 18-month follow-up), which requires good relationships with schools, parents, and adolescent-sensitive procedures.
