The project evaluated the reliability of a computer-assisted health education knowledge quiz, a multiple-choice picture identification assessment tool for nutrition and health-related knowledge in preschool age children. Pearson's product moment correlation coefficients were computed to assess overall and componential stability between test/retest scores of 51 children (mean age 3.6 years) enrolled in a Head Start preschool center. Cronbach alpha coefficients were calculated to determine the internal consistency of the subscales. Overall reliability for the computer-assisted quiz was high at .82 (p < .01). For individual subscales, test/retest correlations were highest for Nutrition, Safety, and Environment (r = .56 to .81) and lower but still significant for Dental, Smoking, and Fitness (r = .37 to .48). Results suggest a computer-assisted knowledge quiz can provide a reliable tool to assess health education knowledge in young children. In addition, the computer-assisted test format is highly acceptable to preschool children and enables researchers to administer a more extensive test to young children with brief attention spans in a manner that engages their full cooperation and effort. In this respect it offers several advantages over traditional paper-and-pencil formats.
该项目评估了一种计算机辅助健康教育知识测验的可靠性，这是一种针对学龄前儿童营养与健康相关知识的多项选择题图片识别评估工具。计算了皮尔逊积差相关系数，以评估就读于启蒙学前教育中心的51名儿童（平均年龄3.6岁）重测分数之间的总体稳定性和各部分稳定性。计算了克朗巴赫α系数，以确定各分量表的内部一致性。计算机辅助测验的总体可靠性较高，为0.82（p < 0.01）。对于各个分量表，营养、安全和环境方面的重测相关性最高（r = 0.56至0.81），而牙科、吸烟和健康方面的相关性较低，但仍具有显著性（r = 0.37至0.48）。结果表明，计算机辅助知识测验可以提供一种可靠的工具来评估幼儿的健康教育知识。此外，计算机辅助测试形式深受学龄前儿童欢迎，使研究人员能够以一种能让他们全力配合并投入精力的方式，对注意力持续时间较短的幼儿进行更广泛的测试。在这方面，它比传统的纸笔形式具有几个优势。
