Following pilot testing, the 17-item Children's Health Ratings Scale was group administered to approximately 1,200 fourth- through sixth-grade students. The internal consistency reliability, concurrent validity, and construct validity of the scale were examined utilizing various statistical methods, including calculation of the alpha coefficient, factor analysis, and other correlational techniques. The scale was found to be reliable with an alpha coefficient of .83. Concurrent validity was supported by the finding that higher scale scores were associated with higher ratings on a single, general health item and with lower ratings on single items concerning pain, health worry, and the presence of sickness. Correlations between scores on the Children's Health Ratings Scale and sex, grade level, and a measure of response bias were of low magnitude and presented no serious threat to instrument validity. Five factors were identified for interpretation during factor analysis. A post hoc validity study compared the mean scale scores of a group of asthmatic children and a subsample from the scale development study. Suggestions for further study are presented.
在进行预试验后，对大约1200名四至六年级学生进行了集体施测，使用的是包含17个条目的儿童健康评定量表。运用多种统计方法，包括计算阿尔法系数、因子分析及其他相关技术，对该量表的内部一致性信度、同时效度和结构效度进行了检验。结果发现该量表具有可靠性，阿尔法系数为0.83。量表得分越高，在单一总体健康项目上的评分越高，而在关于疼痛、健康担忧和患病情况的单一项目上的评分越低，这一发现支持了同时效度。儿童健康评定量表得分与性别、年级水平以及反应偏差测量之间的相关性较低，对工具效度没有构成严重威胁。在因子分析过程中确定了五个可用于解释的因子。一项事后效度研究比较了一组哮喘儿童的平均量表得分与量表编制研究中的一个子样本的得分。文中还提出了进一步研究的建议。
