INVESTIGATING DEVELOPMENTAL RISK FACTORS IN PRESCHOOLERS

该项目的长期目标是更好地了解 学龄前运动功能正常与发育危险因素 语言、认知、自助和行为领域。具体目标 包括改进和验证新成本效益筛查，这些筛查 结合；1)准确预测风险20对全范围的敏感性 轻度到严重的赤字，30文化公平，4)适用于 说西班牙语的孩子。 在第一年，这项研究将包括抽样593名正常人，200名高危人群(in 两个严重程度分组)210会说西班牙语，并具有可靠性 和效度研究。焦点将是一系列的双重交叉- 用于确定以下各项的最佳项目集的验证研究 进一步研究。在第二年，这项研究将包括对1709名正常人进行抽样， 200人处于危险中(在两个严重程度组中)。210会说西班牙语，会指挥 广泛的决策一致性研究。 四个主要目标是：1)建立等值分数和 通过与标准化标准的比较来确定最佳切割点；2) 通过广泛的双交叉建立预测的准确性 验证研究，3)分析短期预测有效性数据和 启动长期预测效度研究，4)开发和 验证西班牙语版本，5)通过分析以下项目来消除项目偏差 大型少数民族群体数据。

The long-term objective of this project is a better understanding of normal preschool functioning and developmental risk factors in motor, language, cognition, self-help and behavior domains. Specific aims include refinement and validation of new, cost-effective screening which combines; 1) accuracy in predicting risk 20 sensitivity to the full range of mild to severe deficits, 30 cultural fairness, 4) applicability to Spanish-speaking children. In Year 1 the study will include sampling 593 normals, 200 at- risk (in two severity grouping) 210 Spanish speaking, and conducting reliability and validity studies. The focus will be a series of double cross- validation studies serving to identify an optimum set of items for further study. In year 2 the study will include sampling 1709 normals, 200 at-risk (in 2 severity groups). 210 Spanish-speaking, and conducting extensive decision consistency studies. The four primary goals are: 1) to establish equivalency scores and optimum cutpoints by comparisons with standardized criteria; 2) to establish the accuracy of predictions through extensive double cross- validation studies, 3) to analyze short-term predictive validity data and initiate a long-term predictive validity study, 4) to develop and validate a Spanish Version, 5) to eliminate item bias by analyzing of large ethnic minority group data.
