摘要： 目的研究4 个常用的脑白质病变分级量表的信度。方法本研究连续入选2007 年8 月～2008 年10 月在北京天坛医院神经内科住院的260 例脑白质病变患者，分别用4 个分级量表评分，重测信度和评定者间信度检验用kappa 相关，内容一致性检验用Cronbach α相关。结果4 个量表的重测信度、评定者间信度及Cronbach α系数均达到统计学意义。Ylikoski 量表的评定者间信度和内部一致性信度最好(评定者间信度kappa=0.656，P<0.01；Cronbach α=0.901)。结论4 个量表在评价脑白质病变中各有其优缺点，建议根据研究的侧重点不同来选择适当的分级方法。

Abstract: Objective To study the reliability of the four rating scales which are widely used. Methods 260 consecutive inpatients fromAug. 2007 to Oct. 2008 with white matter lesions were enrolled into the study. Interrater and intrarater reliability of four scales was analyzedby using kappa correlation. Internal consistency was expressed with Cronbach's α. Results All the scales have statistic significant interraterand intrarater reliability. Scale of Ylikoski has the best intrarater reliability and Cranach's α (intrarater reliability, kappa=0.656, P<0.01, Cranach'sα=0.901). Conclusion The four rating scales for white matter lesions have advantage and disadvantage. Disparate rating scales shouldbe used according to purpose of study.
