To determine the psychometric properties of a new functional assessment tool, the WeeFIM 0-3 instrument, intended to measure function in young children with physical, cognitive, or developmental impairments from birth to 3 years of age. Specific aims were to determine whether differences exist in WeeFIM 0-3 ratings in children with impairments as compared with those without, controlling for age and gender, and to determine the internal consistency, validity, and hierarchical properties of the instrument.
Cross-sectional study of 173 children with impairments and 354 without impairments.
Controlling for age, children without impairments had significantly higher mean WeeFIM 0-3 ratings than children with impairments. There were no differences in mean ratings by gender. The instrument displayed high internal consistency, construct, and predictive validity; maintained a hierarchy of item difficulty; and discriminant properties.
Further reliability studies are needed to determine the instrument sensitivity and ability to detect change over time.
确定一种新的功能评估工具——WeeFIM 0 - 3量表的心理测量特性，该量表旨在测量出生至3岁有身体、认知或发育障碍的幼儿的功能。具体目标是确定与无障碍儿童相比，有障碍儿童在WeeFIM 0 - 3量表评分上是否存在差异，并对年龄和性别进行控制，同时确定该量表的内部一致性、效度和等级特性。
对173名有障碍儿童和354名无障碍儿童进行横断面研究。
在控制年龄的情况下，无障碍儿童的WeeFIM 0 - 3量表平均评分显著高于有障碍儿童。不同性别的平均评分没有差异。该量表显示出高内部一致性、结构效度和预测效度；保持了项目难度等级；并具有区分特性。
需要进一步进行信度研究，以确定该量表的敏感性以及检测随时间变化的能力。
