THE ABC INTERVENTION IN EARLY HEAD START PROGRAMS: REDUCING THE EFFECTS OF TOX

本研究的主要目的是实施一个循证的亲职干预，玩和学习策略（帕尔斯），以评估的作用，亲职质量在缓冲有毒压力与贫困的儿童。具体而言，该项目将：（1）衡量幼儿接触与贫困有关的危险的15个指标，这些危险构成“有毒压力”，并确定接触这些方面与父母养育质量较低和儿童压力生理生物标志物水平升高的相关程度;（2）实施ABC育儿干预，并记录如何在现有的EHS活动中调整和实施干预;（3）评估帕尔斯育儿干预的有效性。对于第三个目标，家庭将被随机分配到（1）家访服务，在定期提供的服务之外，他们将接受10周的干预，或（2）“一切照旧”的对照条件。这项研究的结果预计将推进应用发展神经科学，并有助于该领域的知识基础的作用，早期的头开始在支持养育和缓冲儿童的毒性压力的影响。

The primary purpose of this study is to implement an evidence-based parenting intervention, Playing and Learning Strategies (PALS) to evaluate the role of parenting quality in buffering children from toxic stress associated with poverty. Specifically, the project will: (1) measure young children's exposure to 15 indicators of poverty related hazards, constituting "toxic stress" and determine the extent to which exposure to these dimensions are associated with lower levels of parenting quality and elevated levels of stress physiology biomarkers for children; (2) implement the ABC parenting intervention and document how the intervention can be adapted and implemented within existing EHS activities; and (3) evaluate the efficacy of the PALS parenting intervention. For the third goal, families will be randomly assigned to either (1) home-visiting services where they will receive 10 weeks of intervention in addition to regularly delivered services or to a (2) 'business as usual' control condition. Results from this study are expected to advance applied developmental neuroscience and contribute to the field's knowledge base regarding the role of Early Head Start in supporting parenting and buffering children from the effects of toxic stress.
