使用生态系统理论和阶段顺序建模程序检测调解，本研究探讨了早期发展的背景如何影响学龄前儿童的表现持续注意力和冲动控制的措施。来自1273名欧洲裔美国人和非洲裔美国人参与NICHD早期儿童保育研究的数据被用来确定早期家庭收入需求（INR）和54个月冲动和注意力不集中之间关系的潜在中介。还进行了探索性分析，以确定早期收入，家庭环境，养育压力和结果变量之间的关系是否不同的非裔美国人与欧洲-美国-美国儿童。我们发现适度支持的研究假设，36个月的家庭环境质量介导的INR/注意力的关系。INR占更多的家庭环境得分方差和家庭环境占更多的冲动得分方差的非洲裔美国儿童。家庭环境与欧美人的注意力不集中有关，但与非洲裔美国人无关。版权所有（c）2007约翰威利父子有限公司。
Using Ecological Systems Theory and stage sequential modelling procedures for detecting mediation, this study examined how early developmental contexts impact preschoolers' performances on a measure of sustained attention and impulse control. Data from 1273 European-American and African-American participants in the NICHD Study of Early Child Care were used to identify the potential mediators of the relation between early household income-to-need (INR) and 54-month impulsivity and inattention. Exploratory analyses were also conducted to determine whether the relationships between early income, home environment, parenting stress, and the outcome variables differ for African-American versus European-American-American children. We found modest support for the study hypothesis that 36-month home environment quality mediated the INR/attention relationship. INR accounted for more home environment score variance and home environment accounted for more Impulsivity score variance for African-American children. Home environments were related to inattention in the European-American, but not African-American, group. Copyright (c) 2007 John Wiley & Sons, Ltd.
