The Delis-Kaplan Executive Function System (D-KEFS) Trail Making Test (TMT), a modification of the original TMT, was created to isolate set-shifting (Letter-Number Switching) from other component skills. This was accomplished by including four baseline conditions (Visual Scanning, Number Sequencing, Letter Sequencing, and Motor Speed) and by placing equal numbers of stimuli in the three sequencing conditions. Given that some studies with the original TMT demonstrated a significant effect of education and intellectual functioning on performance, we utilized the D-KEFS national standardization sample to examine the effects of education and vocabulary level-i.e., Vocabulary subtest from the Wechsler Abbreviated Scale of Intelligence (WASI)-on the D-KEFS TMT. The results indicate a significant effect of these variables on each D-KEFS TMT condition. Normative tables for education- and vocabulary-adjusted scaled scores based on the database from the D-KEFS national normative study were generated.
德里斯科尔-卡普兰执行功能系统（D-KEFS）的连线测试（TMT）是对原始 TMT 的修改，旨在将转换（字母-数字转换）与其他组成技能区分开来。这是通过包括四个基线条件（视觉扫描、数字排序、字母排序和运动速度）和在三个排序条件中放置相等数量的刺激来实现的。鉴于原始 TMT 的一些研究表明教育和智力功能对表现有显著影响，我们利用 D-KEFS 全国标准化样本来研究教育和词汇水平（即，来自韦氏智力量表简表（WASI）的词汇分量表）对 D-KEFS TMT 的影响。结果表明，这些变量对每个 D-KEFS TMT 条件都有显著影响。根据 D-KEFS 全国标准化研究数据库生成了基于教育和词汇调整的标化分数的常模表。
