Updating, Expanding, and Interpreting Perry Preschool Data through Midlife

描述（由申请人提供）：本项目的目标是收集，扩增和分析HighScope佩里学前教育计划（PPP）的数据，以调查这种有影响力的早期干预对中年各种结果的影响。佩里学前教育方案是针对弱势非裔美国人人口。通过随机分配的方法进行评估，参与者一直被跟踪到40岁。男孩和女孩花在佩里身上的每一美元的年回报率都在7-10%之间。它在减少犯罪方面特别有效，并对许多其他成果产生了有益的影响，这些成果经受住了严格的检验和统计审查。 佩里的前几次数据收集了非常有限的关于健康和个性的信息，没有关于风险规避、时间偏好、幼儿经历以及退休计划、储蓄和资产头寸的信息，这反映了它最初对促进认知和教育的重视。我们寻求支持，以补充数据集收集信息，同时和回顾性的，对老龄化样本的关键结果。我们将从两个主要的美国调查（HRS，健康和退休调查，和PSID，收入动态的小组研究），以便于与美国老龄化人口中可比人员的结果进行比较。我们将收集有关幼儿的信息，以补充现有的（但以前未使用的）佩里关于早期家庭环境质量的数据。我们还将收集一组生物标志物的客观健康数据，这些生物标志物指示主要调控系统的生理活动，以及使用新创建的适应性测试的认知数据。初步调查数据将补充有关犯罪和死亡原因的行政数据。 有了这种独特的资源，该项目将研究补充弱势非洲裔美国儿童的早期生活环境的中年影响。它将有助于我们理解成人健康的发展起源，并将探索衰老的根源。它将确定早期生活经历影响成年结果的机制，并将调查出生后三年干预时补救措施是否可以持续。它将开发和应用方法来分析小规模实验的数据，并在最初的抽样计划中产生多种结果和变化。使用增强的实验数据，它将增加以前的分析效益成本和回报率的佩里计划，包括利益，如果有的话，对健康和心理健康的人和社会。 在与普利兹克财团在芝加哥大学的伙伴关系，并利用资金，我们将超越元分析比较PPP的结果和机制与其他主要的幼儿计划，包括初学者计划，护士家庭伙伴关系计划，和芝加哥亲子中心。

DESCRIPTION (provided by applicant): The goal of this project is to collect, augment and analyze data on the HighScope Perry Preschool Program (PPP) in order to investigate the effects of this influential early intervention on a variety of outcomes through midlife. The Perry Preschool Program was targeted towards a disadvantaged African American population. Evaluated by the method of random assignment, participants have been followed through age 40. The annual rate of return to each dollar spent on Perry is in the range of 7-10% for both boys and girls. It was especially effective in reducing crime and has had beneficial effects on numerous other outcomes, which survive rigorous testing and statistical scrutiny. Reflecting its initial emphasis on promoting cognition and schooling, previous waves of the Perry data collected very limited information on health and personality and no information on risk aversion, time preferences, early childhood experiences, and plans for retirement, savings and asset positions. We seek support to supplement the dataset by collecting information, both contemporaneously and retrospectively, on key outcomes for an aging sample. We will draw questions from two major US surveys (HRS, the Health and Retirement Survey, and the PSID, the Panel Study of Income Dynamics), to facilitate comparison with outcomes for comparable persons in the aging US population. We will collect information on early childhood which will supplement existing (but previously unused) Perry data on the quality of early home environments. We will also collect objective health data on a set of biomarkers indicating physiological activity across major regulatory systems, and cognitive data using newly created adaptive tests. Primary survey data will be augmented with administrative data on crime and cause of death. Armed with this unique resource, the project will study the midlife effects of supplementing the early life environments of disadvantaged African American children. It will contribute to our understanding of the developmental origins of adult health, and it will explore the roots of aging. It will identify the mechanisms through which early life experiences affect adult outcomes, and it will investigate whether remediation can be sustained when intervening three years after birth. It will develop and apply methods to analyze data from small scale experiments, with multiple outcomes and alterations in the initial sampling plan. Using the enhanced experimental data, it will augment previous analyses of the benefit-cost and rate of return of the Perry Program to include the benefits-if any-on health and mental health both to persons and to society. In partnership with the Pritzker Consortium at the University of Chicago, and leveraging funding with it, we will go beyond meta-analysis to compare the PPP outcomes and mechanisms with those found for other major early childhood programs, including the Abecedarian Program, the Nurse Family Partnership Program, and the Chicago Parent-Child Centers.
