Cognitive & Emotional Mechanisms of Harsh Parenting

描述（由申请人提供）：拟议研究的总体目标是扩展有关过度反应性育儿相关关系的科学知识，着眼于改善针对儿童行为问题的育儿干预措施。根据生物心理社会模型，提出了关于父母对孩子严厉管教的想法和感受以及生理反应的假设。具体目的如下：目的一是检验负面情绪覆盖的普遍性，从不正常的婚姻到问题的母子关系。假设先前的儿童外化问题，互动前儿童相关情绪，期望以及预期情感和心理生理反应与儿童行为和过度反应性纪律的负面偏见评价相关的中介模型。目的2是测试严厉的养育方式与亲子冲突的心理生理反应之间的关系，将生理评估扩展到母亲和幼儿的现场互动中，并包括迷走神经反应性评估（以及皮肤电反应性）。这些关系将在100对母子二人组的样本中进行测试，其中幼儿表现出不同程度的早期外化问题。

DESCRIPTION (provided by applicant): The overarching goal of the proposed study is to expand scientific knowledge regarding the correlates of overreactive parenting, with an eye toward improving parenting interventions that target child conduct problems. Drawing from a biopsychosociai model, hypotheses are offered about how parents' thoughts and feelings about, and physiological responses to, their children relate to harsh discipline. Specific aims are as follows: Aim 1 is to test the generalizability of negative sentiment override from dysfunctional marriages to troubled mother-child relationships. A mediated model in which previous child externalizing problems, preinteraction child-related sentiment, expectations, as well as anticipatory affective and psychophysiological reactivity are associated with negatively biased appraisals of child behavior and overreactive discipline is hypothesized. Aim 2 is to test the relation between harsh parenting and psychophysiological reactivity to parent-child conflict, extending physiological assessment to live interactions of mothers and their toddlers, and including the assessment of vagal reactivity (as well as electrodermal reactivity). These relations will be tested in a sample of 100 mother-toddler dyads in which the toddlers are exhibiting varying degrees of incipient externalizing problems.
