DESCRIPTION (provided by applicant): This study investigates early social and physiological processes involved in the development of self regulation and its relation to infant-mother attachment and cognitive development in high risk infants who vary in their level of neonatal medical risk. The research has a longitudinal design that follows infants from hospital discharge until they are 2 years (corrected for gestational age) and involves data collected from children and families using multiple methods in multiple contexts. The study has 4 specific aims: (1) to examine 3 preverbal predictors of high risk infants' self-regulation, including neurophysiological modulation (early cardiorespiratory processes), quality of mutual regulation (parent-infant interaction), and infant self regulatory disposition (temperament), (2) to investigate parent-infant interaction quality over time as a mediator of the relation between infant/maternal characteristics and infants' cognitive and social outcomes, (3) to identify whether infants varying in risk levels and temperament are differentially susceptible to negative parenting associated with chronic maternal depression, and (4) to identify relations among attachment, cognitive abilities, and self-regulation in high risk infants. The proposed investigation will advance the field of developmental psychopathology by examining longitudinal processes involved in the development of early self-regulation and will extend our knowledge in 3 ways: (1) identification of how infants' perinatal medical risks and early heart rate variability directly and indirectly predict developmental outcomes, (2) testing a model that specifies parent-infant interaction quality as a mediator of the relation between infant neonatal risks, maternal depressive symptoms, and infant developmental outcomes, which has implications for preventive interventions with high risk infants, and (3) identification of relations among self-regulational capacities, attachment relationships and cognitive development in high risk infants, which may provide suggestions for extending developmental follow-up evaluations of NICU graduates to include screening dyadic interactions.

描述（由申请人提供）：本研究调查了新生儿医疗风险水平各异的高危婴儿中自我调节发展所涉及的早期社会和生理过程及其与母婴依恋和认知发展的关系。该研究采用纵向设计，跟踪婴儿从出院到 2 岁（根据胎龄进行校正），并涉及在多种情况下使用多种方法从儿童和家庭收集的数据。该研究有 4 个具体目标：(1) 检查高危婴儿自我调节的 3 个语言前预测因素，包括神经生理学调节（早期心肺过程）、相互调节质量（亲子互动）和婴儿自我调节倾向（气质），(2) 随着时间的推移，研究亲子互动质量作为婴儿/母亲特征与婴儿认知和社交之间关系的中介因素。 结果，（3）确定不同风险水平和气质的婴儿是否对与慢性母亲抑郁相关的消极养育方式有不同的易感性，以及（4）确定高风险婴儿的依恋、认知能力和自我调节之间的关系。 拟议的研究将通过检查早期自我调节发展所涉及的纵向过程来推进发展精神病理学领域的发展，并将以三种方式扩展我们的知识：（1）确定婴儿的围产期医疗风险和早期心率变异如何直接和间接预测发育结果，（2）测试一个模型，该模型指定亲子互动质量作为婴儿新生儿风险、母亲和母亲之间关系的中介因素。 (3) 确定高危婴儿的自我调节能力、依恋关系和认知发展之间的关系，这可能为扩大 NICU 毕业生的发育随访评估以包括筛查二元相互作用提供建议。
