| 目的检验Loewenstein认知评定量表（LOTCA）简体中文版的效度及信度，为其在国内的临床应用提供客观依据。 方法先将LOTCA英文版译成中文，再对2组对象进行测试。病例组（n=35）为脑部疾病患者，男27例，女8例，年龄（61.0±16.7）岁。对照组（n=44）为非脑部疾病的住院患者和陪护人员，男19例，女25例，年龄（55.4±23.7）岁。分别用LOTCA和简易精神状态量表(MMSE) 评定2组对象。将LOTCA结果与MMSE结果作相关性检验，验证LOTCA简体中文版的效度；对LOTCA 2次结果作评定员内部及其之间的相关性分析(ICC)，检验其重复测试信度。 结果LOTCA和MMSE评定结果高度相关(r=0.9852~0.9939)。LOTCA各项内容2次重复测试评定员内部ICC=0.9923(95%可信区间0.9840~0.9960),评定员之间ICC=0.9907（95%可信区间0.9860~0.9940）。病例组和对照组的LOTCA总分分别为（85.05±17.71）和（97.65±16.24）分，两者间差异有显著性意义(P<0.05)。 结论LOTCA简体中文版具有良好的效度、信度和敏感度，可用于临床脑部疾病认知功能的评定。 |
| 英文摘要: |
| Objective To study the validity and reliability of the simplified Chinese version of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA). MethodsThe English version of LOTCA was translated into the simplified Chinese first and then translated back to English to ensure its reliability in Chinese version.The we recruited two groups of volunteers to participate in the study. One group consisted of 36 patients with brain disorders (patient group), The other group consisted of 43 subjects without neurological disorders (control group). All the subjects were assessed with LOTCA and Mini-Mental State Examination (MMSE) within one session and on different days, respectively by two independent raters. Scores of LOTCA and MMSE were analyzed with Spearman correlation coefficient to test the validity of LOTCA. Intra-class coefficients (ICCs) were used to examine the intra-rater and inter-rater reliability of LOTCA. And Mann-Whitney test of non-parameters analysis was used to detect the sensitivity of LOTCA. ResultsThere was high correlation between the scores of LOTCA and that of MMSE (r=0.9852-0.9939). ICCs of LOTCA were 0.9923（P<0.0001）with 95％ interval coefficient 0.9840-0.9963 for intra-rater reliability and 0.9907（P<0.0001）with 95％ interval coefficient 0.9855-0.9941 for the inter-rater reliability. The total scores of LOTCA were 85.05±17.71 in the patient group and 97.65±16.24 in the control group with significant difference between the two groups (P<0.05). ConclusionThe simplified Chinese version of LOTCA is valid, reliable and sensitive. It can be used clinically to evaluate the Chinese subjects with cognitive problems. |
