LONGITUDINAL EFFECTS OF EXTENDED CHILDHOOD INTERVENTION

本延续研究将调查 参与一个既定的，联邦资助的幼儿计划， 成年早期（15至20年后）的社会能力， 在经济上处于不利地位的社区长大的孩子的样本。 讨论了五个主要问题：（a） 参与与更大的社会相关的儿童-家长中心计划 在成年早期的能力？(b)估计延长的影响是什么 干预（4至6年）相对于不太广泛的干预？(c)做 参与计划的估计影响因儿童/家庭风险而异， 项目属性和社区贫困(d)通过什么途径 参与计划的长期效果是什么？（五） 参与者和社会的成本和收益是什么？ 亲子中心计划？25岁以下的社会能力指标 包括教育程度、就业、社会行为（即，犯罪）， 参与社会福利服务和生活质量。同类系列 结果也将得到。 通过将芝加哥纵向研究扩展到成年期， 调查将独特地增加有关预防性措施的影响的知识， 对儿童和家庭的干预。广泛的纵向研究 从幼儿期开始的罕见，特别是对于 中心城市的人口代表性不足。在接下来的五年里，我们 将对1，282名计划和比较组的年轻人进行采访 参与者（93%非裔美国人，7%西班牙裔），获得管理数据 从教育、司法、社会服务体系等方面进行分析和更新 从现有的13年数据库中获取信息。据我们所知， 对一项公共幼儿计划的前瞻性纵向研究， 一直延续到成年。 该研究将提供关于Head长期影响的独特证据。 启动型延长儿童期干预。研究的长期目标 （a）增加关于早期治疗的最佳持续时间和时间的知识 儿童方案，（B）确定谁从早期干预中受益最大， (c)以确定早期干预措施的效果 影响以后的发展，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.
