Baby's First Years (BFY), New York City, New Orleans, Omaha, and Twin Cities, 2018-2019

The overall goal of the Baby's First Years project is to provide the first definitive understanding of the extent to which household income plays a causal role in affecting children's cognitive, socio-emotional, and brain development early in life for children born into low-income families. Some 1,000 mothers of infants with incomes below the federal poverty line were recruited in four diverse U.S. communities between May 2018 and June 2019. All are receiving monthly cash gifts via disbursement on a debit card for the first 40 months of the child's life. Parents in the high cash gift group (n=400) are receiving a cash gift of $333 per month ($4,000 per year), whereas parents in the low cash gift group (n=600) are receiving a cash gift of $20 per month ($240 per year). In order to understand the impacts of the unconditional cash gift on children's cognitive and behavioral development, the researchers will assess high and low cash gift group differences at age 3 (and, for a subset of measures, ages 1 and 2) on measures of cognitive, language, memory, self-regulation, and socio-emotional development. To understand how family economic behavior, parenting, and parent stress and well-being change in response to the cash gift, the researchers will examine high and low cash gift group differences in family expenditures, food insecurity, housing and neighborhood quality; family routines and time use; parent stress, mental health and cognition; parenting practices; and child care arrangements at child ages 1 and 2. Our four data collection points are referred to as: "Baseline", "Age 1", "Age 2", and "Age 3". The current collection includes data and related materials regarding study design from the Baseline data collection. Additional information on the project, survey design, sample, and variables are available from: The User Guide, which is included in this collection under the "Data and Documentation" tab The project's website: babysfirstyears.com The researchers request that all peer-reviewed papers using BFY Data: be submitted to PubMed https://publicaccess.nih.gov immediately upon acceptance for publication include the following citation to the data in their bibliography: Citation Magnuson, K., Noble, K.G., Duncan, G., Fox, N.A., Gennetian, L.A., and Yoshikawa, H.

《婴儿成长初期项目》的总体目标在于深入探究家庭收入在影响低收入家庭出生儿童早期认知、社会情感及大脑发育中所扮演的因果角色。自2018年5月至2019年6月，研究人员在四个美国多元化社区中招募了约1000名月收入低于联邦贫困线的婴儿母亲。所有受试者都将在前40个月的时间里通过借记卡获得每月的现金赠款。在高现金赠款组（n=400）中，父母每月将获得333美元（每年4000美元）的现金赠款；而在低现金赠款组（n=600）中，父母每月将获得20美元（每年240美元）的现金赠款。为了理解无条件现金赠款对儿童认知和行为发展的影响，研究人员将在儿童3岁时（以及部分衡量指标在1岁和2岁时）对高、低现金赠款组在认知、语言、记忆、自我调节和社会情感发展方面的差异进行评估。为了理解家庭经济行为、育儿方式以及父母压力和福祉如何随现金赠款而变化，研究人员还将考察高、低现金赠款组在家庭支出、食品不安全、住房和社区质量；家庭日常活动和时间分配；父母压力、心理健康和认知；育儿实践以及1岁和2岁儿童的照料安排方面的差异。我们的四个数据收集点分别被称为：“基线”、“1岁”、“2岁”和“3岁”。当前收集的数据包括基线数据收集的相关研究设计和材料。关于项目、调查设计、样本和变量的更多信息，可通过以下途径获取：用户指南，该指南包含在“数据和文档”标签下；项目网站：babysfirstyears.com。研究人员要求所有使用BFY数据的同行评审论文在发表接受后立即提交至PubMed，并在参考文献中包含以下数据引用：引用 Magnuson, K.，Noble, K.G.，Duncan, G.，Fox, N.A.，Gennetian, L.A.，Yoshikawa, H.，《婴儿成长初期》（BFY）。基线公共数据，2018-2019。跨大学政治和社会研究联合会[发行者]，2020-11-16。http://doi.org/10.3886/ICPSR37871.v2。包含以下致谢：致谢本研究使用《婴儿成长初期研究》的数据。本出版物中报告的研究得到了美国国家卫生研究院Eunice Kennedy Shriver国立儿童健康和人类发展研究所的资助，资助编号R01HD087384，以及美国卫生与公众服务部儿童和家庭家庭服务办公室、规划、研究和评估办公室、安妮·E·凯西基金会、比尔及梅琳达·盖茨基金会、Brady教育基金、Chan Zuckerberg倡议（硅谷社区基金会）、儿童福利基金、福特基金会、新奥尔良大都会基金会、Heising-Simons基金会、Jacobs基金会、JPB基金会、路易斯安那基金会、纽约市经济机会市长办公室、Perigee基金、罗伯特·伍德·约翰逊基金会、Sherwood基金会、Valhalla慈善基金会、Weitz家族基金会、W.K.
