卒中版蒙特利尔认知评估量表的开发及测评

目的修订适合缺血性脑卒中病人使用的蒙特利尔认知评估量表，并对其信效度进行评价。方法采用文献法、德尔菲法组成专家函询小组，对量表条目进行讨论和修定；对369例符合纳入标准的缺血性脑卒中病人进行问卷调查，应用经典测量理论对量表的信效度进行测评。结果量表总分重测信度为0.94，Cronbach's α值为0.82，Spearman-Brown系数为0.87，Guttman分半信度系数为0.85，表明量表具有较好的信度，相关性分析和探索性因子分析结果显示量表具有较好的结构效度。结论该版本蒙特利尔认知评估量表具有良好的信度、效度，可以作为卒中后认知障碍病人认知功能测评的工具，但仍有进一步改进的空间。
