The validity of the Color Trail Test in the pre-driver assessment of individuals with acquired brain injury

Primary objective: To examine the validity of the Color Trails Test (CTT), a culture- fair analogue of the Trails Test, in the pre-driver assessment of individuals with acquired brain injury (ABI). Research design: Retrospective study. Methods and procedures: 30 participants with ABI completed the CTT and Useful Field of View (UFOV) in a driving rehabilitation clinic. Within the same week an on-road evaluation was conducted by a driving rehabilitation specialist, and a driving instructor. Results: 50% of the participants passed the on-road evaluation and 50% failed. Individuals who passed the on-road test performed the CTT1 and CTT2 faster than those who failed, however the difference between the pass/fail groups was significant only for the CTT1. A correlation analysis between the CTT subtests (CTT1 and CTT2) and the UFOV subtests revealed significant, moderate correlations between these measures. Conclusions: The CTT1 may contribute to the pre-driving screening by rapidly identifying those individuals who are most at risk for unsafe driving behaviors. Further studies are required with a larger representative sample.
