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）：以照顾不足的形式出现的早年逆境与一生中罹患身心疾病的更大风险有关。人们提出，应对压力的自我调节能力是一种将早期家庭经历与长期健康联系起来的机制。尽管对儿童进行了深入研究，但人们对看护经历对成年后自我调节能力的影响程度知之甚少。此外，对压力的认知和情感自我调节反应的个体差异可能介导或调节生理反应。目前的研究将探讨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反应联系起来。参与者将包括 60 名年轻成年男性和女性；一半来自高冲突/低感情的家庭环境，一半来自低冲突/高感情的家庭环境。将进行一项社交互动任务，参与者进行角色扮演，向难相处的邻居（研究团队的同伙）提出请求。将在角色扮演之前和之后的 3 个时间点连续测量血压并测量唾液皮质醇。该任务将被录像并分析消极的言语和非言语行为以及应对方式。任务完成后将评估对情况和同盟者的情绪反应和认知评估。我们假设，与来自低冲突/高情感背景的参与者相比，来自高冲突/低情感家庭环境的参与者在角色扮演过程中会表现出更大的负面情感、适应不良的应对反应、更大的负面认知评价以及更高的皮质醇和血压反应。我们还假设认知/情感反应将介导生理反应。这项研究将提供关于对压力的认知和情绪反应的作用的重要信息，作为将早期护理经历与生理反应和长期健康联系起来的机制。了解心理和生理脆弱性背后的认知和情感机制将有助于阐明和定义对因早期护理不足而变得脆弱的个体进行心理治疗干预的适当目标。
