Longitudinal Effects of Extended Childhood Intervention

描述（由申请人提供）：这项继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%的非洲裔美国人）参加联邦政府资助的建立的早期儿童干预与30岁前成人健康之间的联系。研究涉及五个主要问题：(a)参加CPC学前教育方案是否与20至25岁以后在教育成就、经济自给自足、社会行为、健康状况和行为以及心理健康方面的更大福祉有关？(b)参与4至6年延长干预的效果是否大于参与不太广泛或不系统的干预？(c)参与项目的估计效果是否因儿童和家庭风险、项目属性和社区因素而异？(d)干预效果的认知优势、家庭支持和学校支持机制是否持续到30岁？(e)参加CPC计划的经济效益是否继续超过成本，超过多少？通过进一步将该项目扩展到成人，该研究将记录早期干预的影响和成本效益，这些影响和成本效益跨越了广泛的很少被调查的结果。没有其他关于公共资助的早期儿童项目的研究持续到第三个十年。902个项目的研究样本和487个对照组的参与者分别占原始样本的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取和分析一套全面的新数据，对29/30岁的整个样本进行后续访谈，并分析来自多个来源的现有数据。关键的长期目标是(a)增加对早期干预对成年期影响的认识，包括其时间和持续时间；(b)确定早期干预影响生命过程中健康的持久机制；(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.
