DESCRIPTION (provided by applicant): The proposed study addresses an under-researched, but likely important implication of sleep variations in a particular social and developmental context: It asks how mothers' sleep deficits arise and what they mean for parenting of toddlers. Toddlers create challenges for parents and many parents of toddlers experience sleep deficits, which could amplify the parenting challenges. The study will test a model in which (1) family stressors along with both family and mothers' individual resources influence (2) family chaos, in terms of fewer predictable routines and more noise, which in turn influences (3) mothers' sleep, in terms of extent, fragmentation, and variability, which influences (4) mothers' state levels of cognitive self-regulation, measured in structured tasks, which in turn influences (5) mothers' parenting of their toddlers. The study will also test a set of hypothesized mother temperament moderators of the paths from chaos to sleep (by trait negative affectivity), from sleep to self-regulation to parenting (by trait effortful control and by trait positive affectivity). The study will follow a sample of 250 mothers from toddler age 30 months to toddler age 36 months, and both continuity and predictors of change will be modeled. The sample will be recruited in two geographical areas and represent a range of socioeconomic levels and both European-American and African-American families. The study will advance knowledge about family environment and mother factors influencing mothers' sleep deficits, about how sleep deficits link to self-regulation and parenting, and about how mother temperament dimensions moderate the paths from environment to mother sleep and from mother sleep to self-regulation and parenting. Ultimately, the study will offer new targets for early childhood clinical and prevention research. PUBLIC HEALTH RELEVANCE: This longitudinal study will show how sleep deficits of mothers of toddlers arise from distal stressors and resources and immediate household chaos, and how they come to be associated with parenting deficits via the key mechanism of cognitive self-regulation. Findings will improve prevention and intervention for sleep and parenting problems, and ultimately for early childhood prevention of behavior problems.

描述（由申请人提供）：拟议的研究解决了睡眠变化在特定社会和发展背景下的研究不足，但可能具有重要意义：它询问母亲的睡眠不足是如何出现的，以及它们对养育幼儿意味着什么。幼儿给父母带来了挑战，许多幼儿的父母都经历过睡眠不足，这可能会加剧养育孩子的挑战。该研究将测试一个模型，其中（1）家庭压力源以及家庭和母亲的个人资源会影响（2）家庭混乱，即可预测的例行公事减少和噪音增加，这反过来会影响（3）母亲的睡眠，在程度、碎片化和可变性方面会影响（4）母亲的认知自我调节状态水平（以结构化任务来衡量），这反过来会影响（5）母亲对孩子的养育方式 幼儿。该研究还将测试一组假​​设的母亲气质调节因素，这些调节因素影响着从混乱到睡眠（通过特质消极情感）、从睡眠到自我调节到养育（通过特质努力控制和特质积极情感）的路径。该研究将跟踪 250 名从 30 个月大到 36 个月大的母亲的样本，并对变化的连续性和预测因素进行建模。样本将在两个地理区域招募，代表不同的社会经济水平以及欧裔美国人和非裔美国人家庭。该研究将加深对影响母亲睡眠不足的家庭环境和母亲因素的了解，了解睡眠不足如何与自我调节和养育联系，以及母亲气质维度如何调节从环境到母亲睡眠以及从母亲睡眠到自我调节和养育的路径。最终，该研究将为幼儿临床和预防研究提供新的目标。 公共健康相关性：这项纵向研究将展示幼儿母亲的睡眠缺陷如何由远端压力源和资源以及直接的家庭混乱引起，以及它们如何通过认知自我调节的关键机制与养育缺陷联系起来。研究结果将改善睡眠和育儿问题的预防和干预，并最终改善儿童早期行为问题的预防。
