Color Trails Test: a Brazilian normative sample
The present study aims to evaluate psychometric data on the population of Brazil using of the Color Trails Test (CTT). The instrument was applied to 1,942 subjects who came from the north (1.4%), northeast (10.4%), midwest (7.7%), southeast (65.9%), and south (13.9%) regions of Brazil. Ages varied from 18 to 86 years (M = 40.03 years; DP = 16.02), with 386 males (19.9%) and 1,556 females (80.1%). Regarding schooling, 57 (3%) of participants were illiterate, 1.240 (64%) had primary education and 645 (33%) had a high school and/or superior diploma. The length of schooling ranged from 0 to 14 (M = 7.81, SD = 3.51) years. Good accuracy ratings were obtained using Spearman's coefficient on the main measures of the CTT, including time of execution form 1 (0.76) and form 2 (0.82). Regional variations showed that the northeast region had the worst results on the instrument. Males had better performance on the proposed task, with significant differences between age groups and the worst results for ages greater than 60 years. For both sexes, an increase in score was noticed with increasing age, and better performance was found with increasing levels of education. The present results suggest that the CTT can identify attentional disturbances with significant variations in the time of execution.
