To assess the construct validity of a telephone-administered version of the Mini-Mental State Examination (MMSE).
Validity testing by comparing a telephone version of the MMSE administered first to a face-to-face evaluation done several days later.
Outpatient geriatric assessment center.
100 of 175 consecutive referrals.
MMSE and a brief neuropsychological screening test (BNPS) face-to-face and a telephone version of the MMSE as part of the Adult Lifestyles and Function Interview (ALFI-MMSE).
Test scores of the two MMSE versions correlated strongly for all subjects (Pearson's r = 0.85, P = 0.001) and remained significant for the cognitively intact (P = 0.02) and questionably (P = 0.002), mildly (P = 0.0001), and moderately (P = 0.003) demented. Comparison of the two versions' equivalent 22 items revealed no significant difference for scores of all subjects (P = 0.07) but with a trend toward higher scores in the original version. Diminished hearing, reported either by the subject (P = 0.003) or by the collateral source (P = 0.02) was associated with lower scores on the telephone version. Five individual test items were biased by the route of test administration. Sensitivity and specificity relative to the BNPS were 67% and 100% for the ALFI-MMSE and 68% and 100% for the MMSE, respectively.
The scores on the ALFI-MMSE correlated strongly with the scores of the original version given face-to-face in subjects undergoing geriatric assessment. The results indicate that the ALFI-MMSE could be a useful and economical tool to screen for cognitive impairment.
评估电话版简易精神状态检查表（MMSE）的结构效度。
通过先进行电话版MMSE测试，几天后再进行面对面评估来进行效度测试。
门诊老年评估中心。
175例连续转诊患者中的100例。
MMSE和简短神经心理筛查测试（BNPS）的面对面测试，以及作为成人生活方式与功能访谈（ALFI-MMSE）一部分的电话版MMSE。
两个MMSE版本的测试分数在所有受试者中均呈高度相关（Pearson相关系数r = 0.85，P = 0.001），在认知功能正常者（P = 0.02）、可疑痴呆者（P = 0.002）、轻度痴呆者（P = 0.0001）和中度痴呆者（P = 0.003）中也保持显著相关。对两个版本中相当的22个项目进行比较，所有受试者的得分无显著差异（P = 0.07），但原版得分有更高的趋势。受试者自述（P = 0.003）或旁证者报告（P = 0.02）的听力下降与电话版得分较低有关。五个单项测试项目受测试方式的影响存在偏差。相对于BNPS，ALFI-MMSE的敏感性和特异性分别为67%和100%，MMSE的敏感性和特异性分别为68%和100%。
在接受老年评估的受试者中，ALFI-MMSE的得分与面对面原版MMSE的得分高度相关。结果表明，ALFI-MMSE可能是一种用于筛查认知障碍的有用且经济的工具。
