本研究探讨了评分方法，教育和语言使用的内部一致性的Folstein简易精神状态检查（MMSE）的影响。受过培训的双语工作人员在参与者家中进行MMSE，作为圣安东尼奥老龄化纵向研究家庭评估组合的一部分。受试者包括833名居住在社区的墨西哥裔美国人（MA）和欧洲裔美国人（EA）老年人，年龄在65岁及以上，居住在三个社会文化上不同的社区在圣安东尼奥，德克萨斯州。MMSE的三种评分方法进行了检查：仅连续7分，仅拼写，和连续7分或拼写，以较高者为准。根据评分方法，EA的平均MMSE评分+/-标准差范围为27.7+/-2.4至28.5+/-1.9，MA的平均MMSE评分+/-标准差范围为25.6+/-3.2至27.2+/-2.9，MA的平均MMSE评分+/-标准差范围为22.5+/-4.5至25.5+/-3.5。在三个种族语言亚组中，仅使用连续7观察到最低平均分、最大变异系数和最高α系数。按教育水平分层显示，所有三种评分方法的α系数在高中毕业生中始终低于教育程度较低的群体。序列7是唯一的评分方法，在所有种族，语言和教育亚组中产生了可接受的高α系数。因此，临床医生在进行MMSE时应使用仅连续七次的方法，并警惕受教育程度较高的EA和MA老年人，特别是精通英语的EA和MA中假阴性的可能性增加。
This study examined the effect of scoring method, education, and language usage on internal consistency of the Folstein Mini-Mental State Examination (MMSE). Trained bilingual staff administered the MMSE in participants' homes as part of the San Antonio Longitudinal Study of Aging home-based assessment battery. Subjects included 833 community-dwelling Mexican-American (MA) and European-American (EA) elders, aged 65 and older, residing in three socioculturally distinct neighborhoods in San Antonio, Texas. Three methods of scoring the MMSE were examined: serial sevens only, spelling only, and serial sevens or spelling, whichever was higher. Mean MMSE scores+/-standard deviation ranged from 27.7+/-2.4 to 28.5+/-1.9 for EAs, from 25.6+/-3.2 to 27.2+/-2.9 for MAs interviewed in English, and from 22.5+/-4.5 to 25.5+/-3.5 for MAs interviewed in Spanish, depending on scoring method. Across the three ethnic-language subgroups, the lowest mean scores, largest coefficients of variation, and highest alpha coefficients were observed using serial sevens only. Stratification by educational level showed that alpha coefficients for all three scoring methods were consistently lower in high school graduates than in less-educated groups. Serial sevens only was the only scoring method that yielded acceptably high alpha coefficients across all ethnic, language, and education subgroups. Thus, clinicians should use the serial sevens-only method when administering the MMSE and be alert to the increased potential for false-negatives in more highly educated EA and MA elders, particularly in EAs and MAs proficient in English.
