DESCRIPTION (provided by applicant): The goal in this second revision of our grant is to increase our understanding of the development of very low birth weight (VLBW) children by examining whether five different mutual regulatory (MR) processes observed during a joint play session between mothers and their VLBW (< 1600g) or healthy, term (FT) children at 1 1/2 and 2 1/2 years post term mediate the relation between children's biologic or social risk status and their developmental and behavioral outcomes at 2 1/2 years. Other goals are to evaluate the extent to which VLBW status, co-morbid medical risk, social risk, child gender, and their interactions are related to these MR processes at each age and longitudinally, and to evaluate the stability of MR processes during this time period. Using a microanalytic, computerized scoring system (Child and Caregiver Mutual Regulation System, CCMR), we will code maternal and child affect and behavior from videotapes of the joint play session at each age. Five MR variables (dyadic affect sharing, reparation, synchrony, bi-directionality, and maternal regulatory responsiveness) will be generated using time series analysis and sequential data analytic techniques. The videotapes of the joint play sessions have already been collected as part of a self-funded extension of a larger and completed study of the effect of Neonatal White Matter Disorder (NWMD) on infant neuromotor development from birth to 1 1/2 years post term (RO1 NS33002-01A2, E. Tronick, PI). Using our own funds, we followed 83 (95%) dyads to 2 1/2 years post term. The proposed analyses will be based on the 88 dyads (62% boys, 53% VLBW) that participated in either the lY2 or the 21/2-year visit. At each visit, children's developmental and behavioral functioning (BSID-II MDI & PDI, BRS, language skills) was evaluated, and mothers provided information about demographics, their child's functioning, and their own adaptation. Findings will provide novel information about individual differences in the mother-child relationship in the VLBW population and shed further light on how mother-child interactive processes may mediate the relation between VLBW/medical risk and children's developmental and behavioral outcomes. This information will enhance our ability to design and implement effective prevention and intervention services for VLBW children and their families.

描述（由申请人提供）：我们赠款的第二次修订的目的是通过检查母亲及其VLBW（<1600G）之间的共同游戏期间观察到的五个不同的相互监管（MR）过程，以提高我们对非常低出生体重（VLBW）儿童的发展的理解（VLBW），该过程是在1/2和2 1/2和2 1/2的年龄和2 1/2/2年的孩子之间的发展中的差异（<1600G）和社会上的经验。 2 1/2年的行为结果。其他目标是评估VLBW状况，合并医疗风险，社会风险，儿童性别及其相互作用的程度与每个年龄段和纵向的这些MR过程有关，并在此期间评估MR过程的稳定性。使用微分析，计算机评分系统（儿童和照顾者相互监管系统，CCMR），我们将在每个年龄段的联合游戏会议的录像带中对母亲和儿童的影响以及行为进行编码。 将使用时间序列分析和顺序数据分析技术生成五个MR变量（二元性影响共享，赔偿，同步性，双向方向性和母体调节响应能力）。联合游戏会议的录像带已经被收集，作为对新生儿白质障碍（NWMD）对婴儿神经运动的影响的自资助扩展的一部分，从出生到1 1/2年后（RO1 NS33002-01A2，E.TRONICK，E. TRONICK，PI）。使用我们自己的资金，我们遵循83（95％）的二元组，到期后2 1/2年。拟议的分析将基于参加LY2或21/2年访问的88个二元组（62％男孩，53％VLBW）。在每次访问中，都评估了儿童的发育和行为功能（BSID-II MDI＆PDI，BRS，语言技能），母亲提供了有关人口统计数据，孩子的功能和自己的适应的信息。调查结果将提供有关VLBW人群中母子关系中个体差异的新信息，并进一步阐明了母子互动过程如何介导VLBW/医疗风险与儿童的发育和行为结果之间的关系。这些信息将增强我们为VLBW儿童及其家人设计和实施有效的预防和干预服务的能力。
