The Symbol Digit Modalities Test is a substitution task that is the inverse of the Digit Symbol Test. The familiar task of filling numbers in boxes, and the availability of an oral administration, make this a popular screening instrument for brain impairment. Normative data were previously reported for a variety of clinical groups, but complete information on non-clinical samples across age, education, gender, and socioeconomic status is limited. The present study examines the performance of a community-dwelling control sample across age, education, gender, and income groupings. In a multivariate model, these four variables did not impact test performance. These results support the utilization of the SDMT as a robust screening test for adult neuropsychological impairment.
符号数字模式测验是一项替代任务，它与数字符号测验相反。在方框中填写数字这一常见任务以及可采用口头施测的方式，使其成为一种常用的脑损伤筛查工具。此前已报告了各种临床群体的常模数据，但关于不同年龄、教育程度、性别和社会经济地位的非临床样本的完整信息有限。本研究考察了一个社区居住对照样本在年龄、教育程度、性别和收入分组方面的表现。在一个多变量模型中，这四个变量并未影响测验成绩。这些结果支持将符号数字模式测验用作成人神经心理损伤的可靠筛查测试。
