中文字词识别测验的信度和效度

Reliability and validity of Chinese words and vocabulary discerning test

目的检验中文字词识别测验的信度和效度。方法在全国分层比例抽样的1605人中随机抽取224例，完成一般资料的调查表、中文字词识别测验和中国修订韦氏成人智力量表（WAIS—RC）。结果全量表的Cronbachg＇sα系数为0．97，识字分测验的α系数为0．97，词汇分测验的α系数为0．94，量表的分半信度为0．89～0．97，量表的重测信度为0．73～0．94，表明量表具有较好的内部一致性和稳定性；识字分测验得分与全量表总分的相关系数为0．87，词汇分测验与总分的相关系数为0．92，识字与词汇分测验间的相关系数为0．60；全量表总分与韦氏全量表智商的相关系数为0．72。结论量表编制符合心理测量学要求，具有良好的信度和效度。

Objective To test the reliability and validity of Chinese word and vocabulary discerning test （CWVDT）. Methods 244 subjects from 1605 normal subjects from 5 district of China examined based on general meteria, CWVDT and Weichesler adult Intelligence scale-revised in China （WAIS-RC）. Results The Cronbach＇s α coefficients of CWVDT were 0.97, the split-half reliability were 0.89 - 0.97, and the test-retest reliability ranged from 0.73 - 0.94. The correlations between word-subtest and vocabulary-subtest and the total scores were 0.87 and 0.92. The correlation coefficients between two factor scores were 0.60. Significant correlation was found between the total scores of CWVDT and IQ of WAIS-RC（r=0.72）. Conclusion The CWVDT has acceptable psychometrics properties on reliability and validity.
