本研究探讨了几种不同的程序，以确定发生在简易精神状态检查[MMSE; Folstein，M。F.、Folstein，S. E、& McHugh，P. R.（1975年）。“简易心理状态”：临床医生对患者认知状态进行分级的实用方法。Journal of Psychiatric Research，12，189-198]和改良的简易精神状态检查[3 MS; Teng，E. L.，& Chui，H. C.（1987年）。改良简易精神状态（3 MS）检查。Journal of Clinical Psychiatry，48，314-318]在短期和长期的重测间隔。重测分数取自参加加拿大健康与老龄化研究的老年人样本。（1994年）。加拿大健康与老龄化研究：痴呆症的研究方法和患病率。Canadian Medical Association Journal，150，899-913]，并在间隔5年的两个场合（CSHA-1和CSHA-2）进行了测试。在每种情况下，MMSE和3 MS以大约3个月的间隔施用两次。因此，精神状态测试进行了四次：CSHA-1的第1次和第2次，CSHA-2的第3次和第4次。MMSE和3 MS的平均差异评分和基线评分百分比显示，在短期和长期重测间隔内，组内变化相对较小。一个可靠的变化指数的基础上的线性回归模型控制的实践效果，心理测量误差，由于可靠性低，回归到平均值，并占各种人口变量的影响。因此，该可靠的变化指数提供了比平均重测-测试1差异、基线变化百分比或基于重测-测试1差异评分的可靠变化指数更好的个体参与者发生变化量的估计。提供了变化评分的规范性数据。(c)2004年美国国家神经心理学学会。由爱思唯尔有限公司出版。保留所有权利。
The present study explored several different procedures for determining the amount of change that occurred on the Mini-Mental State Exam [MMSE; Folstein, M. F., Folstein, S. E., & McHugh, P. R. (1975). "Mini-Mental State": A practical method for grading the cognitive state of patients for the clinician. Journal of Psychiatric Research, 12, 189-198] and Modified Mini-Mental State Exam [3MS; Teng, E. L., & Chui, H. C. (1987). The Modified Mini-Mental State (3MS) examination. Journal of Clinical Psychiatry, 48, 314-318] over short and extended test-retest intervals. The test-retest scores were drawn from a selected sample of elderly individuals who participated in the Canadian Study of Health and Aging [Canadian Study of Health and Aging. (1994). The Canadian study of health and aging: Study methods and prevalence of dementia. Canadian Medical Association Journal, 150, 899-913] and were tested on two occasions (CSHA-1 and CSHA-2) separated by 5 years. On each occasion the MMSE and 3MS were administered twice at approximately 3-month intervals. Thus, the mental status tests were administered four times: times 1 and 2 at CSHA-1 and times 3 and 4 at CSHA-2. Mean difference scores and percent of baseline scores showed relatively small group changes over both short and long test-retest intervals for the MMSE and the 3MS. A reliable change index based on a linear regression model controlled for practice effects, psychometric errors due to low reliability, regression to the mean, and accounted for the effects of various demographic variables. Consequently, this reliable change index provided a better estimate of the amount of change that occurred for individual participants than did the mean Retest-Test 1 difference, percent of baseline change, or a reliable change index based on a Retest-Test 1 difference score. Normative data for the change scores are provided. (c) 2004 National Academy of Neuropsychology. Published by Elsevier Ltd. All rights reserved.
