目的：为了确定是否可以从一个简化的11项版本中推导出完整的简易精神状态检查量表（MMSE）范围，该版本旨在测试一个队列中的一般认知功能，其中只有一小部分预计会严重受损或痴呆。使用简单的计算和多重填补，使用来自医学研究理事会认知功能和老化研究的数据，将简化MMSE的特性与完整MMSE评分进行比较。通过假设排除项目的高功能，可以为简化版本生成完整的MMSE评分。在插补评分中，88.8%的评分在其真实值的1分以内。当样本仅限于具有正常认知功能的个体（MMSE总分>= 24/30）时，96.7%的个体被分类在其真实总分的I分之内。该模型工作最好的预测认知水平时，截止分数被用来分类个人到受损与不nonimpaired.Conclusion：全量表MMSE分数可以合理准确地从11项缩写版本。这种简化版本可以应用于其他框架，这些框架需要缩短测试长度，但需要的结果与使用完整版本的研究相当。(C)2011 Elsevier Inc.

Objective: To determine whether the full Mini Mental State Examination (MMSE) scale range can be derived from an abbreviated 11-item version that was designed for testing general cognitive function in a cohort where only a small proportion were expected to be severely impaired or demented.Study Design and Setting: Using simple computation and multiple imputation, the properties of the abbreviated MMSE were compared with the full MMSE score using data from the Medical Research Council Cognitive Function and Ageing Study.Results: Full MMSE scores can be generated for the abbreviated version by assuming high functioning on excluded items. Of the imputed scores, 88.8% were within 1 point of their true value. When the sample was restricted to individuals with normal cognitive functioning (MMSE total score >= 24/30), 96.7% of individuals were classified within I point of their true total score. The model worked best at predicting cognitive level when cutoff scores were used to classify individuals into impaired vs. not nonimpaired.Conclusion: Full-scale MMSE scores can be reasonably accurately derived from an 11-item abbreviated version. This reduced version can be applied within other frameworks that require reduced test length but need results that are comparable to studies where the full version has been administered.
