《儿童智力筛查量表》之有效性研究

本文应用比较研究和因素分析研究方法，从几个方面探讨了《儿童智力筛查量表》的有效性.研究结果表明，《筛查量表》与其它标准化的智能测验具有较高的相关，相关在o.n-o.7s之间，对于弱智儿童的鉴别应用表明，该量表具有很高的鉴别力，正确判别率达0.8G以上.特别是有关“争议儿童”的鉴别研究表明，《筛查量表》在弱智鉴别上是比较有效的.因素分析研究的结采还揭示了《筛查量表》具有三大结构，即言语智能因素、操作智能因素和基本生活知识因素.这三个因素的揭示，从理论上支持了《筛查量表》的有效性.

Research on the Validity of Intelligence Screening Scale for Children

The research storted with generally used Validation methodology based on a batch of testing data. The validity of the Intelligence Screening Scale for Children (ISSC) was studied in several aspects, by using comparative analysis and factor analysis, which provided a lot of reliable and valuable information for the application of the scale in practice. Result showed that the ISSC had high correlations with other standardized intelligence tests. The corelation coefficient was 0.71-0.76. The application of the ISSC in screening the mentally retarded children showed a high discrimination ability, the correct-hitting ratio of which was as high as 0.86. Factor analysis showed that the structure of ISSC had three main components, i.e. verbal intelligence factor (VI), operational intelligence factor (OI) and basic living knowledge factor (BLK). This supported the validity of ISSC in theory.
