LONGITUDINAL EFFECTS OF EXTENDED CHILDHOOD INTERVENTION

这项继续研究将调查 参加一个既定的、由联邦政府资助的儿童早期计划 成年早期的社交能力(课程结束后15到20年) 在经济困难社区长大的儿童样本。 讨论了五个主要问题：(A)是持续时间和时间 参与亲子中心计划与更多的社会 成年初期的能力？(B)延期的估计影响有多大 干预(为期4至6年)相对于范围较小的干预？(C)做 参与计划的估计影响因儿童/家庭风险而异， 项目属性和邻里贫困？(D)有哪些途径可以通过 项目参与实现了哪些非常长期的效果？(E) 对参与者和社会有什么代价和好处 亲子中心计划？25岁以下的社交能力指标 包括教育程度、就业、社会行为(即犯罪) 参与社会福利服务，提高生活质量。相似家庭 也将取得成果。 通过将芝加哥纵向研究扩展到成年人，建议的 调查将独一无二地增加对预防措施效果的了解 针对儿童和家庭的干预措施。广泛的纵向研究 从儿童早期开始是很少见的，特别是对于 中心城市中代表性不足的人口。在接下来的五年里，我们 将对1,282个节目和对比组进行青年采访 参与者(93%的非裔美国人，7%的西班牙裔)，获得行政数据 从教育、司法、社会服务体系等方面进行分析和更新 来自现有13年数据库的信息。我们不知道还有其他 对一项公共儿童早期项目的前瞻性纵向研究 一直持续到成年。 这项研究将为HEAD的长期影响提供独特的证据 启动型儿童扩展干预。这项研究的长期目标 是(A)增加关于早期的最佳持续时间和时机的知识 儿童方案，(B)确定谁从早期干预中受益最大， (C)确定早期干预的效果所通过的途径 影响到以后的发展，以及(D)加强对 项目后环境的作用。

This continuation study will investigate relations between participation in an established, federally-funded early childhood program and social competence in early adulthood (15 to 20 years postprogram) for a large sample of children who grew up in economically disadvantaged neighborhoods. Five major questions are addressed: (a) Is the duration and timing of participation in the Child-Parent Center Program associated with greater social competence in early adulthood? (b) What are the estimated effects of extended intervention (for 4 to 6 years) relative to less extensive intervention? (c) Do the estimated effects of program participation vary by child/family risk, program attributes, and neighborhood poverty? (d) What are the pathways through which the very long-term effects of program participation are achieved? (e) What are the costs and benefits to participants and to society of the Child-Parent Center Program? Indicators of social competence up to age 25 include educational attainment, employment, social behavior (i.e., crime), participation in social welfare services, and quality of life. Similar family outcomes also will be obtained. By expanding the Chicago Longitudinal Study into adulthood, the proposed investigation will uniquely add to knowledge about the effects of preventive interventions for children and families. Extensive longitudinal studies beginning in early childhood are rare, especially for children from under-represented populations in central cities. Over the next five years we will conduct young adult interviews with 1,282 program and comparison-group participants (93% African American, 7% Hispanic), obtain administrative data from educational, justice, and social-service system, and analyze and update information from the existing 13-year data base. We are aware of no other prospective longitudinal studies of a public early childhood program that have continued into adulthood. The study will provide unique evidence about the long-term effects of Head Start-type extended childhood interventions. The long-term goals of the study are (a) to increase knowledge about the optimal duration and timing of early childhood programs, (b) to identify who benefits most from early intervention, (c) to identify the pathways through which the effects of early interventions affect later development, and (d) to enhance theoretical understanding of the role of post-program environments.
