Longitudinal Effects of Extended Childhood Intervention

描述（由申请人提供）：本延续研究将调查在芝加哥纵向研究中，在高度贫困社区长大的一大群儿童（93%为非洲裔美国人）参与一项已建立的联邦资助的儿童早期干预与30岁以下成人健康之间的联系。解决了五个主要问题：（a）参加CPC学前教育计划是否与20至25岁后更好的教育成就，经济自给自足，社会行为，健康状况和行为以及心理健康有关？(b)参与4至6年的扩展干预的效果是否大于参与不太广泛或不系统的干预？(c)参与计划的估计效果是否因儿童和家庭风险、计划属性和邻里因素而异？(d)认知优势、家庭支持和学校支持机制的干预效果是否持续到30岁？（e）参与CPC计划的经济效益是否继续超过成本，超过多少？通过将该项目进一步扩展到成年期，拟议的研究将记录早期干预在广泛的很少调查的结果中的影响和成本效益。没有其他的研究公共资助的幼儿教育项目一直持续到第三个十年。研究样本的902个程序和487个比较组的参与者分别代表了原始样本的91%和89%。在接下来的五年里，我们将从教育、司法系统、公共援助和社会服务记录中获得并分析一套全面的新数据，对整个样本在29/30岁时进行跟踪采访，并分析来自多个来源的现有数据。关键的长期目标是：（a）增加有关早期干预对成年期影响的知识，包括其时机和持续时间;（B）确定早期干预影响整个生命过程中的福祉的持久机制;（c）确定干预相对于其他社会计划的成本效益。

DESCRIPTION (provided by applicant): This continuation study will investigate links between participation in an established, federally-funded early childhood intervention and adult well being up to age 30 for a large cohort of children (93% African American) in the Chicago Longitudinal Study who grew up in high poverty neighborhoods. Five major questions are addressed: (a) Is participation in the CPC preschool program associated with greater well being for educational attainment, economic self-sufficiency, social behavior, health status and behavior, and mental health 20 to 25 later?, (b) Are the effects of participation in extended intervention for 4 to 6 years greater than participation in less extensive or unsystematic intervention?, (c) Do the estimated effects of program participation vary by child and family risk, program attributes, and neighborhood factors?, (d) Do the cognitive advantage, family support, and school support mechanisms of intervention effects persist to age 30?, and (e) Do the economic benefits of participation in the CPC program continue to exceed costs and by how much? By further expanding the project into adulthood, the proposed study will document the impact and cost- effectiveness of early intervention across a wide range of rarely investigated outcomes. No other studies of publicly-funded early childhood programs have continued through the third decade. The study sample of 902 program and 487 comparison-group participants represents 91% and 89% of the original sample, respectively. Over the next five years, we will obtain and analyze a comprehensive set of new data from educational, justice system, public aid, and social-service records, conduct follow-up interviews for the entire sample at age 29/30, and analyze existing data from multiple sources. The key long-term goals are (a) to increase knowledge about the adulthood effects of early intervention, including its timing and duration, (b) to identify the enduring mechanisms through which early interventions affect well being over the life course, and (c) to determine the cost effectiveness of intervention relative to other social programs.
