项目摘要

DESCRIPTION (provided by applicant): Early life adversity in the form of inadequate caregiving has been linked to greater risk of physical and psychological illness over the lifespan. Self-regulatory ability in response to stress has been proposed as a mechanism linking early family experiences to long-term health. Although well-studied in children, little is known about the extent to which caregiving experiences affect self-regulatory ability into adulthood. In addition, individual differences in cognitive and affective self-regulatory responses to stress may mediate or moderate physiological responses. The current study will address this important potential cognitive pathway linking early caregiving experiences to stress-responding in adulthood. Participants will include 60 young adult men and women; half from high conflict/low affection family environments, and half from low conflict/high affection family environments. A social interaction task will be conducted in which participants role-play making a request from a difficult neighbor (a confederate from the research team). Blood pressure will be taken continuously, and salivary cortisol will be measured before and at 3 timepoints following the role-play. The task will be videotaped and analyzed for negative verbal and nonverbal behavior, and coping styles. Emotional responses and cognitive appraisals of the situation and the confederate will be assessed following the task. We hypothesize that participants from high conflict/low affection family environments will display greater negative affectivity during the role-play, maladaptive coping responses, greater negative cognitive appraisals, and elevated cortisol and blood pressure responses relative to those from low conflict/high affection backgrounds. We also hypothesize that cognitive/affective responses will mediate physiological reactivity. This study will provide important information regarding the role of cognitive and emotional responses to stress as a mechanism linking early caregiving experiences to physiological reactivity and long-term health. An understanding of cognitive and emotional mechanisms underlying psychological and physiological vulnerability will help to articulate and define appropriate targets for psychotherapeutic intervention with individuals rendered vulnerable by inadequate early caregiving.

描述（由申请人提供）：以不足的护理形式的早期逆境与生命周期内的身体和心理疾病的更大风险有关。已经提出了响应压力的自我调节能力，作为将早期家庭经历与长期健康联系起来的机制。尽管在儿童中得到了充分的研究，但对照料经历影响成年能力的程度知之甚少。此外，认知和情感自我调节反应的个体差异可能会介导或中度的生理反应。当前的研究将解决这一重要的潜在认知途径，将早期护理经历与成年后的压力响应联系起来。参与者将包括60名年轻男女；一半来自高冲突/低情感家庭环境，一半来自低冲突/高感情家庭环境。将执行一项社交互动任务，参与者的角色扮演从一个困难的邻居（研究小组的同盟国）提出请求。血压将连续服用，并在角色扮演后3个时间点之前和在3个时间点上测量唾液皮质醇。该任务将进行录像和分析，以了解负面的口头和非语言行为以及应对风格。在任务后，将评估对情况和同盟的情感反应和认知评估。我们假设，来自高冲突/低情感家庭环境的参与者将在角色扮演期间表现出更大的负面情感，适应不良的应对反应，更大的负面认知评估，皮质醇升高和与低冲突/高情感背景的皮质醇和血压反应升高。我们还假设认知/情感反应将介导生理反应。这项研究将提供有关压力的认知和情感反应的重要信息，这是将早期护理经验与生理反应性和长期健康联系起来的机制。对心理和生理脆弱性背后的认知和情感机制的理解将有助于阐明和定义适当的心理治疗干预目标，以使个人因早期护理不足而变得脆弱。
