摘要
目的 :评价电话版常识 -记忆 -注意测验 (TelephoneInformation -Memory -Concentrationtest ,T-IMCT)应用的信度和效度。方法 :痴呆病人共 65例 ,对照组健康老年志愿者 67例。采用修改后T -IMCT在面访两周之后对全部受检对象电话访问一次。结果 :时间重测信度相关系数为 0 93 (P <0 0 1) ,评定员重测信度相关系数为 0 90 (P <0 0 1)。面访和电话访问评分的相关系数为 0 92 (P <0 0 1)。T -IMCT电话评定痴呆的敏感性为 80 % ,特异性为 80 6%。T -IMCT与MMSE的相关系数为 0 89(p <0 0 1)。结论 :T -IMCT具有良好的信度和效度 ,可以应用于痴呆的筛查。
Objective:To examine the reliability and validity of the telephone version of Information-Memory-Concentration Test (T-IMCT) in screening dementia when administered by telephone To evaluate the relation of the face-to-face and the telephonic interview for assessing the cognitive status Methods:T-IMCT was adapted from Information-Memory-Concentration test for the telephonic interview 65 subjects with dementia and 67 normal control subjects were examined by an experienced clinician, including clinical, neuropsychological and instrumental examination (CT or MRI) T-IMCT was administrated by telephone after 2 weeks, comparing the score from face-to-face interview with telephonic interview 20 subjects were administered the test twice by the same doctor to measure the test-retest reliability, and another 20 subjects were administered the test by two doctors to measure the inter-rater reliability Informants supervised the subjects to insure the authenticity of assessment administered by telephone Results:T-IMCT achieved a sensitivity of 80% and specificity of 80 6% in differentiating demented from healthy control subjects There was a high correlation between face-to-face interview and telephonic interview, Pearson’s correlation coefficient was 0 92 (P<0 01) T-IMCT also demonstrated satisfactory inter-rater reliabilities (r=0 90,P<0 01) and test-retest reliabilities (r=0 93,P<0 01) The total T-IMCT scores were correlated with MMSE (r=0 89,P<0 01) Conclusion:The findings suggest that the T-IMCT is a valid assessment tool for screening dementia by telephone The scale was readily acceptable and considered being a useful adjunct in screening of dementia
