Emotion Regulation and Cortisol in Children with Atopy

描述(申请人提供)：这项研究将考察早期生活经历，通过暴露于心理社会风险因素和早期儿童疾病事件，如何影响7岁儿童在二元互动中的情绪调节。具体地说，这项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)，对亲子互动的量化观察，以及父母对儿童行为的报告。这项研究将包括一组低收入、多种族的城市儿童(n=158)，他们在婴儿期有多次喘息。纵向数据将允许检查整个童年时期的心理社会风险因素和疾病事件对以后情绪调节的影响。在实验室参观时，每个孩子都将进行静脉穿刺术，观看幽默电影，并参与有组织的亲子互动任务。每名儿童的唾液皮质醇将在访问期间收集5次。数据分析将检验(1)儿童生理应激反应、二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二元情绪调节。本研究的结果将有助于更好地理解早期生活经验如何影响儿童早期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.
