计算机与手册式简明精神分裂症认知评估测验的比较

目的比较简明精神分裂症认知评估测验（Brief Assessment of Cognition in Schizophrenia,BACS）的计算机与手册式版本对精神分裂症患者认知功能评定的结果。方法60例符合DSM-IV诊断标准的精神分裂症患者分为两组，30例先接受计算机BACS测验，4周后接受手册式BACS测验；另30例先接受手册式测验，4周后接受计算机测验。然后将两组数据交叉合并，采用配对t检验，比较计算机及手册式版本BACS的结果有无差异。结果在BACS中7项分测验中，除代币运动（TM）为手工操作外，其它分测验涉及计算机与手册式施测的不同，包括符号编码（SC）、言语记忆（VM）、数字序列（DS）、语义流畅性（CF）、字词流畅性（WF）、伦敦塔（TL）。这些分测验的比较t值分别为-0．339（P-0．736）、-1.901（P=0．062）、-1．549（P=0．127）、0．807（P=0．423）、0．121（P=0．904）、-．744（P=．008），两种版本的5项分测验之间无统计学意义，仅有伦敦塔具有差异性。结论BACS的计算机与手册式版本之间总体上无显著性差异，因此，可以认为BACS计算机化版本是基本成功的，改进后可以推广使用。

Comparison of Manually-administered and Computerized Version of Brief Assessment of Cognition in Schizophrenia

Objective To compare the test results of manually-administered and computerized version of Brief Assessment of Cognition in Schizophrenia(BACS).Methods 60 patients who meeted DSM-IV criteria for Schizophrenia were randomly divided into two groups,with 30 patients receiving computerized version in one group,while 30 patients receiving manual version in another group.After 4 weeks,two groups received different versions respectively.The difference between two groups was determined using paired-sample t-test.Results Except Token Motor Test which is administered manually twice,six BACS subtests,such as Symbol Coding Test(SC),Verbal Memory(VM),Digit Sequencing(DS),Category Fluency(CF),Word Fluency(WF) and Tower of London(TL) have different versions,and the t-test value between manual version and computerized version of six subtests were-0.339(P=0.736),-1.901(P=0.062),-1.549(P=0.127),0.807(P=0.423),0.121(P=0.904),-2.744(P=0.008) respectively,among which results of 5 subtests had no significant difference between two versions,except from Tower of London test with significant difference.Conclusion The test results of BACS computerized version are basically consistent with that of BACS manually-administered version.
