PROJECT SUMMARY/ ABSTRACT Infant development is largely shaped by caregiver-infant interactions, and such interactions are often impaired in families at risk of maltreatment. During healthy caregiver-infant interactions, caregivers and infants co- construct physiological and behavioral exchanges – known as concordant coregulation – that are thought to support infant adaptation to stress and serve as an important biomarker of risk. In maltreating families, this coregulation manifests as discordance between caregiver and infant physiology and behavior, thereby increasing vulnerability for poor infant development. While evidence suggests discordance in maltreating mother-infant dyads – that is, a negative or absence of association of mother-infant coregulation over time – the extent to which fathers can match their infant’s physiological and behavioral states remains unanswered. Moreover, despite knowledge that fathers are often overrepresented as perpetrators of more severe forms of maltreatment, we lack an advanced understanding of the role of fathers in exacerbating or protecting against maltreatment risk as well as in shaping infant regulatory processes and developmental outcomes. This study will be among the first to examine patterns of mother-infant versus father-infant biobehavioral coregulation among families oversampled for risk. The goal of this study is to advance understanding of the etiology of child maltreatment and infant development in terms of the role of individual and dyadic caregiver-infant regulation and address the following aims: (1) examine patterns of coregulation among mother-infant versus father-infant dyads, and (2) investigate the extent to which patterns of mother-infant versus father-infant coregulation affects maltreatment risk and infant development. Study methods will involve a brief, longitudinal design with self- report, observational, physiological, and behavioral assessments of 60 families from dual-caregiver households with an infant between 6 to 9 months old. This study will have high impact because it will elucidate novel dyadic biobehavioral processes and the role of fathers in affecting maltreatment risk and infant development. Collectively, this work has translational implications for identifying mechanistic pathways to inform maltreatment prevention and intervention programming to promote health and wellness among high-risk caregiver-infant dyads.

项目摘要/摘要 婴儿的发育在很大程度上是由护理人员互动的形成，这种相互作用通常受到损害 在有虐待风险的家庭中。在健康的护理人员相互作用中，护理人员和婴儿共同 构建生理和行为交流（称为一致的基调），被认为是 支持婴儿适应压力并成为重要风险的重要生物标志物。在虐待家庭中，这个 核心调节表现为看护人与婴儿生理和行为之间的不一致，从而表现出 增加婴儿发育不良的脆弱性。虽然证据表明虐待不一致 母亲二元组（即随着时间的流逝，母亲核心调节的负面或没有关联） 父亲可以与婴儿的身体和行为状态相匹配的程度仍未得到答复。 此外，欲望知道，父亲通常会因为更严重的形式的肇事者而过多地代表 虐待，我们对父亲在加剧或保护中的作用中缺乏深入的理解 虐待风险以及塑造婴儿监管过程和发展结果。这项研究 将是第一个检查母子与父亲生物行为的模式的模式之一 在因风险而过采样的家庭中。这项研究的目的是提高对儿童病因的理解 虐待和婴儿的发育在个人和二元护理人员的角色方面 并解决以下目的：（1）检查母亲与父亲侵害的核心调节模式 二元组和（2）研究母子与父亲的核心调节的多大程度 虐待风险和婴儿发展。研究方法将涉及简短的纵向设计 来自双重照顾者家庭的60个家庭的报告，观察，身体和行为评估 婴儿在6至9个月之间。这项研究将产生很大的影响，因为它将阐明新颖 二元生物行为过程以及父亲在影响虐待风险和婴儿发展中的作用。 总的来说，这项工作对识别机械途径的转化含义 虐待预防和干预计划，以促进高风险的健康和健康 护理人员侵入二元组。
