希—内学习能力测验在中国聋儿中使用的信度和效度

采用经部分修改的希－内学习能力测验（Ｈ－ＮＴＬＡ）量表对全国２１个省、市、自治区１７５８名３－１７岁聋儿逐人测试。样本人群地区分布、家长职业构成与１９９０年全国人口普查资料一致。１７５８名聋儿智商呈现正态分布（ｇ１＝０．０１１Ｐ＞０．０５，ｇ２＝０．０５８Ｐ＞０．０５）。测试员间信度系数０．９８１（Ｎ＝２４），复测信度０．８４１（Ｎ＝１３６），分半信度０．９２７（３－８岁）及０．８５４（９－１７岁）。各分测验得分随年龄增加而增加，小年龄组增加明显，大年龄组增加缓慢。各分测验之间、各分测验和总离差智商之间大多数相关系数有显著统计学意义。智商与学习成绩（语文及数学）相关系数０．２０８（Ｐ＜０．０１Ｎ＝２２４），与教师评语等级相关系数０．４４（Ｐ＜０．０５ｄｆ＝１６），表明经修订的Ｈ－ＮＴＬＡ量表适用于中国听力语言障碍人群进行智力评定。

TI Reliability and validity of H-NTLA on deaf children in China

he revised H NTLA was given to a representative sample of 1758 deaf children from 21 provinces and cities in China,wihin the age range of 3 to 17 years.The distribution of the geography and occupation of their fathers were consistent with data from population sampling in 1990.The reliability between testers was 0 981,the test retest reliability was 0 841.Employing the split half method and the Spearman Brown formula,coefficients of reliability were found to be 0 927in 3 8 year group and 0 854 in 9 17 year group respectively.The distribution of the subjcts'IQ was normal,skewnesshad g1=0 0105 and kurtosis g2=0 0578. In the younger group,the raw score and chronological age correlated closely.In the older age group,where the age difference were smaller,the higher interrelations among the subtests were found,and correlation between the age ratings on each subtest and the IQ for the total test were also significant.The correlation coefficient between their academic achievements (Chinese and Mathematics)and their IQs was 0 208(p<0 01 N=224).The correlation coefficient between teachers rating and IQs was 0 44(p<0 05)
