Longitudinal Effects of Extended Childhood Intervention

描述(由申请人提供)：这项继续研究将调查芝加哥纵向研究中在高贫困社区长大的一大群儿童(93%非裔美国人)参加既定的、由联邦政府资助的儿童早期干预措施与30岁以下成年健康之间的联系。讨论了五个主要问题：(A)参加CPC学前项目是否与更好的教育成就、经济自给自足、社会行为、健康状况和行为以及20至25岁后的心理健康有关？(B)参与扩展干预4至6年的影响是否大于参与不太广泛或不系统的干预？(C)项目参与的估计影响是否因儿童和家庭风险、项目属性和邻里因素而异？(D)干预效果的认知优势、家庭支持和学校支持机制是否会持续到30岁？和(E)参加CPC方案的经济收益是否继续超过成本，以及超出多少？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的影响和成本效益，涉及范围广泛的很少调查的结果。在第三个十年中，没有其他关于公共资助的儿童早期项目的研究继续进行。902名计划参与者和487名对照组参与者的研究样本分别占原始样本的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和分析一组全面的新数据，在29/30岁时对整个样本进行后续采访，并分析来自多个来源的现有数据。主要的长期目标是：(A)增加对成人早期干预影响的认识，包括其时机和持续时间；(B)确定早期干预影响生命周期幸福感的持久机制；(C)确定干预相对于其他社会项目的成本效益。

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.
