This study examined processes of change associated with the positive preschool and kindergarten outcomes of children who received the Head Start REDI intervention, compared to "usual practice" Head Start. In a large-scale randomized-controlled trial (N = 356 children, 42% African American or Latino, all from low-income families), this study tests the logic model that improving preschool social-emotional skills (e.g., emotion understanding, social problem solving, and positive social behavior) as well as language/emergent literacy skills will promote cross-domain academic and behavioral adjustment after children transition into kindergarten. Validating this logic model, the present study finds that intervention effects on three important kindergarten outcomes (e.g., reading achievement, learning engagement, and positive social behavior) were mediated by preschool gains in the proximal social-emotional and language/emergent literacy skills targeted by the REDI intervention. Importantly, preschool gains in social-emotional skills made unique contributions to kindergarten outcomes in reading achievement and learning engagement, even after accounting for the concurrent preschool gains in vocabulary and emergent literacy skills. These findings highlight the importance of fostering at-risk children's social-emotional skills during preschool as a means of promoting school readiness. The REDI (Research-Based, Developmentally-Informed) enrichment intervention was designed to complement and strengthen the impact of existing Head Start programs in the dual domains of language/emergent literacy skills and social-emotional competencies. REDI was one of several projects funded by the Interagency School Readiness Consortium, a partnership of four federal agencies (the National Institute of Child Health and Human Development, the Administration for Children and Families, the Assistant Secretary for Planning and Evaluation in the Department of Health and Human Services, and the Office of Special Education and Rehabilitation Services in the Department of Education). The projects funded through this partnership were designed to assess how integrative early interventions for at-risk children could promote learning and development across multiple domains of functioning. In addition, the projects were charged with examining processes of change and identifying mechanisms of action by which the early childhood interventions fostered later school adjustment and academic achievement. This study examined such processes of change, with the goal of documenting hypothesized cross-domain influences on kindergarten outcomes. In particular, this study tested whether gains in the proximal language/emergent literacy and social-emotional competencies targeted during Head Start would mediate the REDI intervention effects on kindergarten academic and behavioral outcomes. In addition, it tested the hypothesis that gains in social-emotional competencies during preschool would make unique contributions to intervention effects on both academic and behavioral outcomes, even after accounting for the effects of preschool gains in language and emergent literacy skills.
本研究考察了接受“启智计划”REDI干预的儿童与接受“常规做法”的启智计划的儿童相比,在学前和幼儿园阶段取得积极成果所涉及的变化过程。在一项大规模随机对照试验中(N = 356名儿童,42%为非裔美国人或拉丁裔,均来自低收入家庭),本研究检验了这样一种逻辑模型:提高学前儿童的社会情感技能(如情绪理解、社会问题解决和积极的社会行为)以及语言/早期读写技能,将促进儿童进入幼儿园后的跨领域学业和行为调整。为验证这一逻辑模型,本研究发现,REDI干预针对的近端社会情感和语言/早期读写技能在学前阶段的提升,介导了干预对幼儿园三个重要成果(如阅读成绩、学习参与度和积极的社会行为)的影响。重要的是,即使在考虑了学前阶段词汇和早期读写技能的同步提升之后,学前阶段社会情感技能的提升对幼儿园阅读成绩和学习参与度的成果仍有独特贡献。这些发现凸显了在学前阶段培养高危儿童社会情感技能对于促进入学准备的重要性。REDI(基于研究、考虑发展因素)强化干预旨在补充和加强现有启智计划在语言/早期读写技能和社会情感能力这两个领域的影响。REDI是由跨部门入学准备联盟资助的几个项目之一,该联盟由四个联邦机构组成(国家儿童健康与人类发展研究所、儿童与家庭管理局以及卫生与公众服务部规划与评估助理部长办公室、教育部特殊教育与康复服务办公室)。通过该合作关系资助的项目旨在评估针对高危儿童的综合早期干预如何能够促进多个功能领域的学习和发展。此外,这些项目还负责研究变化过程,并确定幼儿干预促进后期学校适应和学业成就的作用机制。本研究考察了此类变化过程,目的是记录对幼儿园成果的假设性跨领域影响。具体而言,本研究检验了启智计划期间针对近端语言/早期读写和社会情感能力取得的进步是否会介导REDI干预对幼儿园学业和行为成果的影响。此外,它还检验了这样一种假设:即使在考虑了学前阶段语言和早期读写技能进步的影响之后,学前阶段社会情感能力的进步对学业和行为成果的干预效果仍有独特贡献。
