项目摘要

DESCRIPTION (provided by applicant): Mothers play a critical role in facilitating the development of biobehavioral regulation in the child. However, marital conflict is related to a host of negative parenting practices, and marital conflict's effect on parenting behavior is thought to be a key mechanism leading to child maladjustment. Despite strong evidence that conflict and hostility between marital partners spillsover to effect parenting behaviors, mechanisms explaining how affect and mood transfers between dyadic familial relationships remains poorly understood. However, theoretical and empirical frameworks suggest marital conflict to be a major stressor, and responsible for changes in stress responsive physiological systems. To date, no study has examined marital stress physiology as a mechanism by which marital conflict impedes the ability for a child to behaviorally and physiological regulate in the face of challenge. The proposed study aims to fill this knowledge gap by examining the extent to which marital conflict induced maternal stress physiology reduces a mother's ability to respond sensitively to her infant during distress. We will then address the implications for the infant, by examining the degree to which the infant physiologically reacts and recovers from distress with maternal support. Participants will include 150 married parents living with their biological child approximately 6 months of age. Using a randomized controlled design, we will assign couples to engage in either a conflict discussion (N= 75) or a non-conflict discussion (N=75) before engaging in a mother-infant freeplay. After the freeplay, the mother will be asked to soothe her distressed infant (the infant will undergo a standardized laboratory procedure designed to elicit distress). Four saliva samples will be collected from the mother surrounding the marital discussion and four samples will be collected from the infant surrounding the distress task. Samples will later be assayed for cortisol and salivary alpha amylase, markers of the two major components of the psychobiology of the stress response (the hypothalamic pituitary adrenal axis and the autonomic nervous system, respectively). We will first examine if marital conflict induced stress physiology is responsible for reduced sensitivity in maternal caretaking. We will then examine if maternal stress physiology is a mechanism by which maternal stress is transmitted to her infant by examining infant physiological reactivity and recovery to challenge with maternal support. PUBLIC HEALTH RELEVANCE: The proposed study aims to identify the physiological mechanisms by which marital conflict spills over into parenting behaviors and effects infant regulation. Specifically, we will be examining the effects of physiological reactivity surrounding marital conflict on maternal behavior and the infant's physiological reaction to, and ability to recover from distress with maternal support. The identification of physiological mechanisms is relevant because their discovery will provide a deeper understanding of the causes of maternal behavior and the implications for the development of child regulation, and provide the basis for new targets of family-based interventions.

描述（由申请人提供）：母亲在促进儿童生物行为调节的发展方面发挥了关键作用。但是，婚姻冲突与许多负面的育儿习俗有关，婚姻冲突对育儿行为的影响被认为是导致儿童疾病的关键机制。尽管有充分的证据表明，婚姻伴侣之间的冲突和敌对行为会影响育儿行为，但解释了二元家族关系之间的影响和情绪转移的机制仍然很差。但是，理论和经验框架表明，婚姻冲突是主要的压力源，并负责压力响应式生理系统的变化。迄今为止，还没有研究婚姻压力生理，作为一种机制，婚姻冲突阻碍了面对挑战时行为和生理调节的孩子的能力。拟议的研究旨在通过检查婚姻冲突引起的孕产妇压力生理学的程度来填补这一知识差距，从而降低了母亲在痛苦中对婴儿的敏感性反应的能力。然后，我们将通过检查婴儿生理反应并在孕产妇的支持下从痛苦中恢复过的程度来解决对婴儿的影响。参与者将包括150名已婚父母与亲生孩子约6个月大。使用随机控制的设计，我们将分配夫妻进行冲突讨论（n = 75）或非冲突讨论（n = 75），然后再进行母亲freeplay。自由戏剧结束后，将要求母亲抚慰她的苦恼婴儿（婴儿将接受旨在引起困扰的标准化实验室程序）。将从婚姻讨论周围的母亲那里收集四个唾液样本，并将从围绕遇险任务的婴儿中收集四个样本。后来，将分析样品的皮质醇和唾液α淀粉酶，这是应激反应心理生物学的两个主要成分的标志物（分别为下丘脑垂体肾上腺轴和自主神经系统）。我们将首先检查婚姻冲突引起的压力生理学是否导致孕产妇照顾的敏感性降低。然后，我们将检查产妇应激生理学是否是一种机制，通过检查婴儿的生理反应性和恢复以在孕产妇的支持下挑战孕产妇应力。公共卫生相关性：拟议的研究旨在确定婚姻冲突蔓延到育儿行为并影响婴儿调节的生理机制。具体而言，我们将研究围绕婚姻冲突对孕产妇行为和婴儿生理反应的生理反应性的影响，以及在孕产妇支持下从痛苦中恢复过来的能力。生理机制的识别是相关的，因为它们的发现将更深入地了解孕产妇行为的原因以及对儿童调节的发展的影响，并为基于家庭的干预措施的新目标提供了基础。
