项目摘要/摘要
在过去的三十年里,人们对童年的长期后果产生了极大的兴趣
虐待(CM)及其与幸存者及其子女的社会情绪适应的关系之前
研究将心肌梗塞病史与成人人际功能的许多领域联系起来,包括风险增加
对于抑郁、焦虑和父母角色中的问题。尽管越来越多的兴趣反映在
文献中,关于CM可能的相关机制,我们仍然有很多不知道或不了解的地方
对有虐待史的女性的抑郁、焦虑和育儿困难,也没有生理上的
可能支持这些联系的途径。这项拟议的研究旨在确定
CM可能与情绪障碍(如抑郁症)易感性增加有关的机制,如
以及对有虐待史的女性的不那么敏感和更具侵入性的育儿行为。我们将招募
71名第一次怀孕的母亲和她们6个月大的婴儿,一半有自我报告的虐待史,一半有
没有。母亲们将参加实验室评估,以确定她们的生理应激反应
使用标准化的社会压力测试来诱导下丘脑-垂体-肾上腺(HPA)和
交感神经系统(SNS)反应。此外,还有10分钟的亲子自由游戏互动
家庭将被视频记录和编码,以应对敏感和侵入性的育儿行为。鉴于普遍存在的

英文摘要
Project Summary/Abstract
The past three decades have witnessed an explosion of interest in the long-term consequences of childhood
maltreatment (CM) and its association with the socioemotional adjustment of survivors and their children. Prior
research links CM history with numerous domains of adult interpersonal functioning, including increased risk
for depression, anxiety, and problems in the parental role. Despite the growing interest reflected in the
literature, there is still much we do not know or understand about the mechanisms by which CM may be related
to depression, anxiety, and parenting difficulties among women with abuse histories, nor the physiological
pathways that may underpin these associations. The proposed study aims to identify the biological
mechanisms by which CM may be related to increased vulnerability to mood disorders, such as depression, as
well as less sensitive and more intrusive parenting behaviors for women with abuse histories. We will recruit
seventy first time mothers and their 6-month old infants, half with self-reported maltreatment history and half
without. Mothers will participate in laboratory assessments to characterize their physiologic stress response
phenotype using a standardized social stress test to elicit hypothalamic-pituitary-adrenal (HPA) and
sympathetic nervous system (SNS) reactivity. Additionally, a ten minute parent-child free play interaction in the
home will be video-recorded and coded for sensitive and intrusive parenting behavior. Given the pervasive
effects of CM across multiple domains of functioning, this study will make a significant contribution to the
literature by identifying salient intermediate psychobiological variables that mediate the relationship between
CM and adult well-being and parenting behavior.
My training plan has been crafted to provide me with the essential components to successfully implement this
study and prepare me to be an independent investigator and to build a research portfolio that will incorporate
stress biomarkers to the study of parenting behaviors of mothers with maltreatment histories. The first is to
develop a knowledge base of the stress-responsive neuroendocrine axes (HPA and SNS) in order to
investigate their dysregulation in women with a history of CM. The second goal is to expand my knowledge of
the epidemiology and sequela of CM to better understand how maltreatment may impact the wellbeing of
multiple generations. The third goal is to develop the skills, expertise, and training that will facilitate my
successful transition from a mentored investigator into a fully independent research scientist capable of
securing R01 funding. The training articulated in this proposal including the timing, collection and analyses of
stress-induced neuroendocrine data, gaining proficiency in mediational analysis using biomarker data, and
grant writing, will provide the skills to conduct high impact research identifying critical points of early
intervention and, thus, improve prevention efforts aimed at reducing the lifelong burden of CM.
