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）：本研究调查了涉及自我调节发展的早期社会和生理过程及其与新生儿医疗风险水平不同的高危婴儿的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（校正胎龄），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。该研究有四个具体目标：（1）探讨高危儿自我调节的3个前言语预测因子，包括神经生理调节（早期心肺过程），相互调节的质量（亲子互动）和婴儿自我调节倾向（气质），（2）探讨亲子互动质量在婴儿与父母互动关系中的中介作用。母亲特征与婴儿的认知和社会结果，（3）确定风险水平和气质不同的婴儿是否对与慢性母亲抑郁症相关的消极父母有不同的易感性，（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。 拟议的调查将通过检查参与早期自我调节发展的纵向过程来推进发展精神病理学领域，并将从3个方面扩展我们的知识：（1）确定婴儿的围产期医疗风险和早期心率变异性如何直接和间接预测发育结果，（2）检验一个模型，该模型将父母-婴儿互动质量指定为婴儿新生儿风险、母亲抑郁症状和婴儿发育结果之间关系的中介，这对高危婴儿的预防干预具有意义，（3）探讨高危新生儿自我调节能力、依恋关系与认知发展的关系，为NICU毕业生的发展随访提供参考。
