摘　　要：目的对EC301计算和数字加工成套测验汉语修订版(EC301-CR)进行信度和效度检验,确定其诊断分界值,为失算症诊断和疗效评定提供有效的测验工具。方法对EC301成套测验量表进行修订,应用修订量表对随机抽取的脑损伤组患者103例和健康人37名进行测验。间隔6周后随机从正常组中抽取24例进行重测。结果 EC301成套测验汉语修订版(28个项目)的Cron-bach'sα=0.907;分半信度为0.744;重测相关系数为0.965;各项目与其所属领域间的相关系数均高于该项目与其他领域间的相关系数;因子分析抽取4个主成分,累计贡献率为69.359%,依次为心算、数字编码转换、笔算和估算以及数字理解,与量表的理论构想基本一致。37名正常人EC301-CR总分的P10为222.6分。结论 EC301-CR总分低于222.6分诊断为失算症。EC301汉语修订版具有良好的信度、效度,是较好的标准化失算症诊断工具。Objective To analyze the reliability and validity of Revised EC301 Calculation and Number Processing Battery in Chinese version（EC301-CR）;To establish diagnostic criteria by EC301-CR for acalculia in order to provide an effective assessment tool clinically.Methods The items of EC301 were adjusted.103 patients with acquired brain injury and 37 normal controls were randomly selected.24 nor-mal controls randomly selected were retested 6 weeks latter.Results The Cronbach＇s coefficient,the split-half reliability and the retest reli-ability coefficients were 0.907,0.744,and 0.965,respectively.The correlation coefficient within subscales was more than the correlation co-efficient between subscales.4 first-order factors were extracted which accounted for 69.359% of the accumulated variance,which were men-tal calculation,number transcoding,written calculation and approximation,and understanding of numbers.Control data（n=37） showed that the P10 of EC301-CR was 222.6.Conclusion The critical value of acalculia is 222.6 in EC301-CR test.Psychometric properties analysis shows that EC301-CR is a reliable and validated instrument for acalculia.
