Emotion Regulation and Cortisol in Children with Atopy

描述（由申请人提供）：本研究将探讨早期生活经验，暴露于心理社会风险因素和儿童早期疾病事件，影响7岁儿童的情绪调节在二元互动。具体来说，本研究将利用三种不同的方法来评估情绪调节：儿童的生理应激反应（即，皮质醇）、亲子互动的量化观察以及父母对儿童行为的报告。该研究将包括一个低收入，多种族，城市人口的儿童（n=158），在婴儿期多次喘息发作。纵向数据将允许检查的影响，心理社会风险因素和疾病事件在整个儿童期以后的情绪调节。在实验室访问中，每个孩子都将进行静脉穿刺，观看幽默电影，并参与结构化的亲子互动任务。在访视期间，将采集每个儿童的唾液皮质醇5次。本研究的目的是：（1）儿童的生理应激反应、双元情绪调节和父母对儿童情绪调节的感知之间的关系;（2）心理社会危险因素和疾病事件如何预测儿童的生理应激反应和双元情绪调节。本研究的结果将有助于更好地了解早期生活经验如何影响幼儿疾病儿童的亲子互动，并为亲子二元体的干预提供信息。

DESCRIPTION (provided by applicant): This study will examine how early life experiences, evidenced by exposure to psychosocial risk factors and early childhood illness events, affect 7-year-oid children's emotion regulation in dyadic interactions. Specifically, this study will utilize three different methodologies of assessing emotional regulation: children's physiological stress response (i.e., cortisol), quantified observations of parent-child interactions, and parent report of children's behavior. The study will include a low-income, multi-ethnic, urban population of children (n=158) with multiple episodes of wheezing in infancy. Longitudinal data will allow for examination of the impact of psychosocial risk factors and illness events throughout childhood on later emotion regulation. At a laboratory visit, each child will have a venipuncture, watch humorous movies, and participate in a structured parent-child interaction task. Each child's salivary cortisol will be collected 5 times during the visit. Data will be analyzed to examine (1) relationship among Children's Physiological Stress Response, Dyadic Emotion Regulation, and Parent Perceptions of Children's Emotion Regulation and (2) how psychosocial risk factors and illness events predict Children's Physiological Stress Response and Dyadic Emotion Regulation. Results of the present study will contribute to a better understanding of how early life experiences affect parent-child interactions among children with early childhood illness and inform interventions with the parent-child dyad.
