INVESTIGATING DEVELOPMENTAL RISK FACTORS IN PRESCHOOLERS

该项目的长期目标是更好地了解 正常的学前功能和运动发育危险因素， 语言、认知、自助和行为领域。具体目标 包括改进和验证新、具有成本效益的筛选方法， 结合; 1）预测风险的准确性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 讲西班牙语的孩子 在第一年，研究将包括抽样593名正常人，200名高危人群（ 两个严重性分组）210西班牙语，并进行可靠性 有效性研究。焦点将是一系列的双重交叉- 验证研究，用于确定一组最佳项目， 进一步研究在第二年的研究将包括采样1709正常， 200例处于风险中（2个严重程度组）。210西班牙语和指挥 广泛的决策一致性研究。 四个主要目标是：1）建立等值分数， 通过与标准化标准的比较确定最佳临界点; 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， 启动长期预测有效性研究，4）开发和 验证西班牙语版本，5）通过分析 大少数民族数据。

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.
