普通话版伯明翰认知评估量表的常模及在广州人群中的信度检验

摘要

Objective There are no currently effective cognitive assessment tools for patients who have suffered stroke in China.The Birmingham Cognitive Screen (BCoS) has been shown to be a promising tool for revealing patients' post-stroke cogni-tive deficits in specific domains.The Cantonese version of BCoS has been proved to be an effective tool for the detection of cogni-tive problems in Cantonese speakers.Here we aim to set up normative data for the mandarin version of BCoS and examine its relia-bility in Guangzhou.Methods We recruited a total of 135 healthy individuals in our study.All the subjects were assessed with the mandarin version of the BCoS.Based on the results ,a norm for the Mandarin version of BCoS was set up.We calculated the Cron-bach's alpha to test the internal consistency reliability ,and the test-retest reliability was examined by calculating the Wilcoxon signed rank tests.Results We set up a norm for the Mandarin version of BCoS.The Cronbach's alpha was 0.785 ,which indicated decent internal consistency reliability.Most of the subtests of the BCoS-Canonese version had good test-retest reliability based on the Wilcoxon signed rank tests results.Conclusion This study suggests good reliability of the BCoS-Mandarin version ,which is worthy of clinical promotion.%目的 国内目前缺乏针对脑卒中后认知障碍的测评量表,伯明翰认知评估量表(BCoS)以筛查卒中后认知障碍为目的,其粤语版的信度、效度已经得到检验,本研究拟建立普通话版伯明翰认知评估量表的常模及检验其在广州人群中的信度.方法 在广州地区纳入135例健康老年人,所有受试者均行普通话版伯明翰认知评估量表测评,在此基础上建立普通话版伯明翰认知评估量表常模.本研究通过计算克朗巴赫系数评价该量表的内部一致性,同时对其中的11名受试者进行随访,通过Wil-coxon signed rank检验评价其重测信度.结果 本研究建立了普通话版伯明翰认知评估量表的常模,内部一致性信度检验显示该量表有较好的内部一致性(克朗巴赫系数为:0.785),重测信度检验显示普通话版BCoS量表大多数亚项目有较好的重测信度.结论 普通话版BCoS量表具有较好的信度,适于进一步推广使用.
