中文洛文斯顿作业疗法认知评定软件的编制及其效度、信度分析

Development of a Chinese application software for Loewenstein Occupational Therapy Cognitive Assessment and its validity and reliability

目的利用软件技术将第二版洛文斯顿作业疗法认知评定（LOTCA）量表开发为中文应用软件系统，并对其标准效度及重测信度进行考察。方法根据第二版LOTCA原版量表的操作、评分方法及基本思想将其转化为计算机软件测试系统。共选取41例脑部伤病患者作为研究对象，将其随机分为A、B两组，分别在2周时间内采取原版LOTCA量表（原版）和软件版测试系统对其认知功能进行测试（2组的测试顺序相反）以分析该系统的标准效度；A组受试者于软件版测试完成2周后再次予以软件版测试以分析其重测信度。结果41例患者软件版与原版LOTCA测试的各项条目得分间均具有较好的相关性（r=0．608～0．983，P〈0．01），配对秩和检验则显示两版测试各条目得分问差异无统计学意义（Z=0．227～1．890，P〉0，05）；A组20例患者前、后2次软件版测试的各条目得分间均具有良好的相关性（r=0．805-0．952，P〈0．01），且配对秩和检验显示2次测试各条目得分间差异无统计学意义（Z=0．378-1．732，P〉0．05）。结论本研究开发的LOTCA中文应用版软件具有较好的标准效度及重测信度，适合应用于我国临床认知功能的康复评定领域。

Objective To develop Chinese application software for Loewenstein Occupational Therapy Cognitive Assessment（LOTCA） and analyze its validity and reliability. Methods The second edition of LOTCA was transformed into the Chinese application software （CAS）. Forty-one patients with brain injuries were randomly divided into A and B groups. The criteria validity of CAS was analyzed with cognitive assessment of computerized and original editions of LOTCA, while the test-retest reliability of CAS was evaluated with CAS again 2 weeks after the first assessment of CAS in group A. Results There was positive correlation between computerized and original edition of LOTCA, the first and second assessments of CAS in group A （ r = O, 608 - 0. 983, P 〈 0.01 ; r = 0. 805 - 0. 952,P 〈 0.01） ,and there was no significant difference in scores of two editions, twice assessments of CAS with Wilcoxon singed rank test（Z=0.227-1.890,P〉0.05; Z=0.378-1.732,P〉0.05）, respectively. Conclusion CASof LOTCA with satisfying criteria validity and test-retest reliability might be worth being used in the clinic work of cognitive assessment and rehabilitation.
