Normative data on trail making test for neurologically normal, Chinese-speaking adults

This study presents normative data on the Trail Making Test Part A and the Chinese version of the Trail Making Test Part B (C-Trails B). The ages of the 110 participants ranged from 21 to 75 (M = 48, SD = 14.7) and years of education from 1 to 20 (M = 12, SD = 5). No gender effects were found on the test scores; however, age and education were significantly associated with scores on both Trails A (p <.01) and C-Trails B (p <.01). Results also suggest a high correlation (Pearson r = .69) between C-Trails B and the Digit Symbol-Coding subtest of the Wechsler Adult Intelligence Scale-Third Edition. In light of our earlier study, this finding provides further evidence that C-Trails B may be equivalent to the standard Trails B. Findings also demonstrate a need for norms adjusted for both age and education for adults whose primary language is Chinese.
