摘要
目的:研制测量精神运动功能的方法和标准,用以评估亚临床克汀病的患病率。方法:用初次标准化时(1994)的10项测验,置换其中4项作为本次测验项目。在六大行政区中按人口比例确定样本量,采用分层取样。结果:常模样本取自16个省的7～14岁1690名城市儿童和1742名农村儿童,男女各半,分成8个年龄组,制定城市和农村二种常模。信度和效度检验:30名受试相隔4个月后复测相关系数为045至093。经项目间相关分析保留7项分测验,累积贡献率为678%,经方差极大旋转得到4因素模型。样本的原始成绩随年龄增长且差异显著。经临床试用具有较好的特异性。结论:本测验是测量精神运动功能的有效工具,不仅为诊断亚临床克汀病所用,亦是评估其它脑功能受损的方法。
To provide the method and standard for measuring psychomotor ability and to estimate the prevalence of subcretins. Methods:JPB includes seven subtests. Stratified sampling was used according to population distribution in six districts in China. Results:The normal samples selected from 16 provinces were composed of 1 690 children living in urban and 1 742 in rural areas. These children were divided into 8 groups aged 7～14 years and the gender ration was 1∶1. Reliability and validity were calculatd and the coefficients of retest reliability reached 0.45 to 0.96 4 months later. The cumulative contribution rate reached 67.8%. A four factors model was established based on varmax likelyhood and varmax rotation method. The raw scores increased at successive ages with significant difference ( P <0.05). Some of the clinical reports proved that JPB had good discrimination. Conclusion:JPB is a satisfactory tool for measuring psychomotor ability. It can be applied not only in subcretin, but can also be used to detect brain damage.
