The Seven Minute Screen (7MS) is a brief cognitive case-finding instrument for dementia. The test is composed of four subtests that assess performance with regard to orientation, memory, visuospatial ability and language. The objective of this study was to describe 7MS performance in a normal sample of people aged 65 years and older.
The subjects were 66 Norwegian community-dwellers who met selection criteria modified from the Mayo Older American Normative Studies standard. Mean age was 73.2 years, age range was 65-93 years, and mean Mini-Mental State Examination score was 29.06, range 26-30.
Analysis of the 7MS subtests revealed relatively modest influence of age, education and gender on test performance. The composite 7MS performance scores were associated with education. Normal performance was expressed as means, standard deviations and percentile values for the age groups 65-74 years and 75 + years.
7MS performance is described for a normal sample. These data have the potential to increase the clinicians' ability to interpret 7MS test results.
七分钟筛查量表（7MS）是一种用于痴呆症的简短认知筛查工具。该测试由四个子测试组成，评估定向、记忆、视觉空间能力和语言方面的表现。本研究的目的是描述65岁及以上正常人群样本的7MS表现。
研究对象为66名符合从梅奥老年美国人常模研究标准修改而来的入选标准的挪威社区居民。平均年龄为73.2岁，年龄范围为65 - 93岁，简易精神状态检查表平均得分为29.06，范围为26 - 30。
对7MS子测试的分析显示，年龄、教育程度和性别对测试表现的影响相对较小。7MS综合表现得分与教育程度相关。以65 - 74岁和75岁及以上年龄组的均值、标准差和百分位数表示正常表现。
描述了正常人群样本的7MS表现。这些数据有可能提高临床医生解读7MS测试结果的能力。
