The objective of this correlational descriptive study was to explore the relationship between depression and attention on patients with mild traumatic brain injury (MTBI). The Spanish version of The Stroop Color and Word Test and the Beck Depression Inventory-II were applied to a sample of 64 participants between 19 and 61 years old. The t, chi square and Pearson correlation tests were applied. In the healthy controls there was no significative relation, while in the patients with MTBI a relationship in the condition of the color-word from the Stroop Color and Word Test was identified.
